00:43Human society is facing a profound transformation in its growth drivers and development patterns.
00:50Solving global development problems for the future
00:54Innovation is the only way.
01:00Wisdom is not as good as accomplishment.
01:04A new narrative of technological revolution is about to unfold in the world today.
01:09Keep abreast of the times
01:10Dare to challenge the forefront
01:13China's development wisdom centered on innovation
01:17Going global
01:19Influencing the world
01:21Embrace the World
01:35This is Xu Rendong's fifth trip to the Maldives within a year.
01:39This archipelago nation in the Indian Ocean
01:42A 1,115-kilometer-long high-speed underwater sightseeing line is about to be laid.
01:48Connect all six main islands of the Maldives
01:53After completion
01:54Maldives will move from Tier 2 to Tier 4.
02:08The construction vessel Emarene was docked in this area of waters
02:11It is the most crucial part of the project.
02:15The world's longest single-strand jointless sea hyacinth fence
02:19It will be laid here.
02:23The interior of the ship is 12 meters in diameter
02:26Giant cable cabin 6 meters high
02:30This is the final inspection before laying.
02:34This is 318.5 kilometers long
02:37220-ton underwater light rail
02:42It is three times the length of a regular sea urchin enclosure.
02:50Xu Rendong is the creator of this sea-light railing.
02:54He must ensure that Haiguanglan undergoes long-distance transportation.
02:57Still intact
03:02Core technologies for manufacturing sea light railings
03:04A Chinese factory 5,000 kilometers away
03:10This is Asia's largest optical fiber preform production base.
03:15It is also the source of Haiguanglan's manufacturing.
03:19This machine jungle
03:21It controls tens of thousands of process parameters in the production of optical fiber preforms.
03:26To ensure that hundreds of valves open correctly
03:29The operator must hang the valve status warning sign.
03:37Each valve
03:38Every temperature must be accurate.
03:42Even the slightest deviation can affect the signal transmission of an ultra-long frieze.
03:48performance
03:52This is the preform of an optical fiber preform.
03:55The main components are high-purity silicon dioxide and refractory dioxide.
04:00To operate at temperatures exceeding 1500 degrees Celsius
04:03Sintered into optical fiber preforms
04:16The entire firing process
04:18The furnace temperature must always be controlled within ±0.1 degrees Celsius.
04:27A two-story sintering furnace
04:30The furnace temperature changed from nearly 300 degrees to 25 degrees.
04:33Up to dozens of temperature control points
04:36Staff must closely monitor
04:42More than twenty hours later
04:46The high-purity airless cannon's light rod has been fired.
04:52There are nearly a thousand factors affecting sintering, including smoke and process parameters.
04:57Previously
04:57This core technology
04:59Always by Corning Incorporated
05:01Friend of Japan
05:02A few major European light preform manufacturers, such as Prisman, control [the market].
05:06In the light stick part
05:07In fact, we have always been a very, very
05:10This is a very important pain point in the development process.
05:16It's this process of controlling the temperature by ±0.1 degrees Celsius.
05:20Chinese engineers have been developing this for over thirty years.
05:24Find each parameter
05:26And their combinations
05:29The digestion and R&D team conducted tens of thousands of experiments.
05:32It consumed hundreds of tons of raw materials
05:38Now
05:39They independently developed a complete set of light rod production processes.
05:42This allows the plant to produce 2,200 tons of optical fiber preforms annually.
05:47If all these light rods are drawn into optical fibers
05:50It can circle the Earth nearly 1,500 times.
05:59Workers are suspending light bars into the Las furnace.
06:04A three-meter-long
06:06200 mm diameter light bar
06:08To achieve uninterrupted operation within 48 hours
06:127500 kilometers
06:14Annealing tubes are the core component
06:18Before Las Vegas
06:20Workshop director Hu Changquan was to clean the annealing tubes.
06:24This is a crucial step in determining Laszlo's continued and outstanding quality.
06:31The light rod melts into a softened state at a high temperature of 2200 degrees Celsius.
06:36After passing through a one-meter-long annealing tube
06:39Gradually cooled to a glass rod with a diameter of 5 mm
06:44At this time, the worker repeatedly pulled.
06:47Cut the glass rod
06:49Repeated for 30 minutes
06:51Let the glass rod gradually shrink
06:54When the diameter reaches more than 100 micrometers
06:56The Lass process officially started
07:05This type of Shiying annealing tube was independently developed by China.
07:07Completely solved the problem of foreign graphite annealing tubes
07:11The defect of excessive dust generation due to high-temperature liquid oxidation.
07:18The pipe diameter is doubled.
07:19It allows for more stable airflow.
07:22This increased Lass speed by 40%.
07:28High-speed rotation of the winding machine
07:30Drives optical fibers at speeds exceeding 3000 meters per minute.
07:34Complete Las
07:38Breakthrough in core optical fiber preform technology
07:42To fiber manufacturing
07:46China has achieved complete self-reliance.
07:56Fiber optic cables like these
07:59China can produce 5 million bolts annually.
08:03Total length 250 million new kilometers
08:07Ranked first in the world
08:21This sea area will be a test site for China's submarine optical cables.
08:25A key station for production and laying capabilities
08:35With Amar's command
08:36The laying of submarine optical cables has officially begun.
08:41Can it be completed successfully?
08:44This is crucial to whether China can enter the international telecommunications infrastructure construction sector.
08:48high-end field
08:50Better serve the international market
08:55Landing craft with tow ropes
08:57We must be the first to land.
09:02Traction ropes on land machinery
09:04The submarine optical cable is moving slowly.
09:09Mobile login deployment method
09:11Unlike direct deployment in deep-sea areas
09:15Staff every five meters
09:16Attach a red buoy to the submarine optical cable
09:20Under the combined action of the buoy and the pulling force
09:23The submarine optical cable is advancing towards the opposite shore at a speed of five meters per minute.
09:30at present
09:3195% of the world's international communications rely on submarine optical cables.
09:36Compared to other communication methods such as satellite
09:39Submarine optical cables have low latency
09:42Long lifespan
09:43Large amount of industrial and information technology
09:45Advantages such as strong confidentiality
09:48The red buoy traced a red line on the sea surface.
09:52underwater
09:53The submarine optical cable is proceeding along its predetermined route.
09:56Slowly extending
09:59Just before this paving project
10:02Google and Facebook had previously made high-profile announcements.
10:05Jointly lay an ultra-high-speed submarine optical cable
10:09The future 5G era
10:10Production and laying of submarine optical cables
10:12It will become a high ground for competition in the information field among countries.
10:17Can Chinese companies join the high-end club of international submarine optical cables?
10:21Victory or defeat hinges on this moment
10:26at this time
10:28Submarine optical cables have reached nearshore areas.
10:58Submarine optical cable landing
11:00Divers remove buoy
11:02Submerge the submarine fiber optic cable into the seabed
11:08The Maldives is the world's largest coral island nation.
11:12During the natural descent of the submarine optical cable
11:14It is very likely that it will hang and touch the coral reef.
11:19Engineers need to bend the submarine optical cable to the maximum extent possible.
11:22Bypassing the coral reef
11:24Protect the marine ecosystem
11:27This forces submarine optical cables to withstand enormous tension.
11:31This improves the flexibility and tensile strength of China's submarine optical cables.
11:35These are all great tests.
11:38Xu Rendong is very confident about this.
11:41Because in their factory
11:43Ensure the submarine optical cable is flexible enough
11:45Has unique skills
11:52Chinese-made submarine optical cables
11:54The optical fiber is made of 27 steel wires.
11:58Armor that can be bent and stretched
12:02Traditional submarine optical cable manufacturing process
12:05It is a two-section dragon horn machine
12:07With 24 steel wires
12:10This three-section dragon horn machine
12:1227-wire braiding method
12:14Original in China
12:17Three-section dragon horn machine
12:19The specifications of the steel wires that each horned dragon uses are different.
12:23The three added steel wires
12:25With 24 other steel wires
12:27A combination of thick and thin materials forms a stable structure.
12:30Improve the flexibility of submarine optical cables
12:33At the same time, it greatly enhances tensile strength.
12:55Submarine scattering
12:57A cliff appeared ahead.
12:59This is an extreme working condition that challenges the bending performance of submarine optical cables.
13:04Nearly 70-degree cliff
13:06For submarine optical cables to be attached to the seabed
13:09The bending radius must be less than 1.5 meters.
13:12Far exceeding the international standard of 3 meters
13:19After nearly 10 hours of firing and repeated adjustments by the divers
13:25Successfully bypassed the cliff
13:33diver
13:34Divers need to install a positioning tag every 15 meters.
13:37In order to track the location and quality of each segment of the submarine optical cable in the future.
13:43One by one, the positioning signs were fixed.
13:45This marks the successful verification of each segment of the submarine optical cable.
13:51Indian Ocean seabed
13:53China's submarine optical cables continue to extend.
13:57It only took 32 days
13:59A 1,115-kilometer submarine optical cable connecting six islands
14:03The entire installation was completed.
14:09Chinese and Maldivian engineers
14:12At the site where the last section of the submarine optical cable was laid
14:15I had an unforgettable New Year.
14:19From this day onward
14:20Maldives becomes the country with the widest communications coverage in South Asia.
14:28Engineers laying facilities in the Maldives
14:28Later, like the entire NPLS engineering team...
14:31and SLT engineers
14:32So those engineers
14:35It is a very, very high
14:37Engineers in the world
14:39This type of optical cable is being laid in the Maldives.
14:42Our three projects have exceeded 1000 kilometers.
14:44We fought this battle for more than five years.
14:46Therefore, in the not-too-distant future
14:48Our goal is not to prohibit this area of the Maldives.
14:51We hope to cross the Pacific Ocean quickly.
14:52Like the vast expanse of the Atlantic Ocean
14:58World Optical Communication Field
15:00China is already a rising force that cannot be ignored.
15:04In terms of broader big data infrastructure construction
15:09China's footprint continues to extend
15:20The workers are installing the world's first PRE 5G prototype.
15:26A laboratory verification of 5G space division multiplexing technology is about to begin.
15:40The devices used in this PRE 5G signal test were ordinary 4G mobile phones.
15:45China's goal is to allow users to switch to 4G phones without having to change their devices.
15:50You can enjoy 5G-like high speeds by replacing only a portion of the base station equipment.
15:56High bandwidth
15:57This is a Chinese solution that benefits both users and the country.
16:07Each phone is downloading at a high speed of about 4 megabytes per second.
16:16Xiang Genomics, a 5G R&D engineer, is the designer of this Chinese solution.
16:21He and his team closely monitored the data traffic of the test phones.
16:26The test lasted nearly two hours
16:28The background data consistently remained at around 1400 MB per second.
16:32Spectrum resource utilization efficiency reached 8 times that of 4G
16:37Then such a test
16:39It uses 5G's MXM space division technology.
16:40Perform a validation process in the design process beforehand.
16:43The purpose of this verification is to facilitate future 5G reuse.
16:46lay a good foundation
16:49Laboratory test successful
16:51Just the first step
16:53400 mobile phones are far from enough to simulate
16:56Complex changes in real-world environments
16:59Camera hard drives need a larger testing ground
17:06Three months later
17:08A grand concert
17:10It's about to begin
17:12Off the field
17:13A black specially made bus
17:16And a 30-meter-high iron tower with nine PRE 5G base stations suspended on it.
17:21They will be with 60,000 fans' mobile phones
17:24First real-world demonstration of 5G spatial division multiplexing technology
17:45This specially designed 5G test vehicle needs to continuously drive around the test site.
17:50He will monitor all signals within a two-kilometer radius of the concert venue.
18:00Real-time data fed back from the base station by camera hardware monitoring
18:04If during peak hours
18:05Mobile data usage at the concert venue remained stable at 300 MB/s.
18:10The verification passed.
18:11How are our preparations going?
18:13The situation of delaying should be prepared by now.
18:16We plan to test point by point.
18:18The test route is the one we drew.
18:20There are a total of 10 points.
18:23From 4G to 5G
18:25Just like traffic speeding up
18:28If we compare signals to vehicles
18:30Roads are likened to bandwidth
18:33Want to speed up
18:34Or widen the road
18:36Either make the car smaller
18:41Space division multiplexing technology uses antennas
18:44Constructing a virtual mapping channel
18:46This is equivalent to setting up multiple virtual roads.
18:49Let more signals run on different virtual roads
18:53Achieving efficient utilization of spectrum resources
18:56This is the creation of Chinese engineers.
19:15The concert reached its climax.
19:18Live mobile phone broadcast
19:20Post on WeChat Moments
19:21Test signal
19:22Very smooth
19:24Completely smooth
19:28Other vehicles please take note
19:29Our speed began to increase
19:31More stringent verification is underway.
19:35At high speeds
19:37Multiple phones quickly approached each other.
19:39mutual signal interference
19:41This will cause a rapid drop in traffic.
19:46Repeated testing
19:48Single user traffic at concert venue
19:50Stable at 30 megabits per second
19:52In-car mobile data
19:54Stable at 40 megabits per second
19:57China's air separation multiplexing technology
19:59First real-world scenario test
20:01Successfully completed
20:06If we use the traditional 4G...
20:08Because spectrum resources are relatively limited.
20:10In many dense scenarios
20:11It will then have problems.
20:13Space division multiplexing technology is particularly effective at this time.
20:15It can operate without changing resources.
20:17Increase this efficiency exponentially
20:215G test vehicles are traveling across the country.
20:24Thousands of large-scale tests are underway

31:01Suddenly divert everyone's attention
31:04Choose the top right corner of the chessboard.
31:06Another robbery situation has emerged.
31:11Rich experience
31:13Let the resolution quickly create a breakthrough.
31:15Secure the victory in one fell swoop
31:34The scene was silent for a full ten minutes.
31:37Dipson was able to concede defeat.
31:40The decision to win the championship
31:51We've finished playing today.
31:52Amazing!
31:53Amazing!
31:54Liu Yongsheng immediately
31:56Video call with the Shenzhen team
31:58Sharing exciting news
32:07The experience of the resolution
32:09Making the Chinese R&D team the focus of the entire event
32:13The two sides in the decisive battle are both opponents
32:15Also friends
32:16Japanese colleagues all spoke with Liu Yongsheng
32:19They exchanged research and development experiences.
32:22This artificial intelligence has pure Chinese origins.
32:25This demonstrates China's strength in scientific and technological research and development.
32:29In the new round of artificial intelligence competition
32:32A large number of Chinese companies have taken the lead and occupied the first tier.
32:38Artificial intelligence is the core of the new round of information technology revolution.
32:42We, China, have a responsibility to work together with our partners around the world.
32:45To collaborate and develop the intelligent brain of our future humankind
32:49As the core driving force of the new round of technological revolution and industrial transformation
32:54The enormous energy unleashed by artificial intelligence
32:57Rapidly cultivating and developing new growth drivers
33:01Towards the Future
33:03China has a responsibility to participate in major scientific projects that are crucial to the future of humanity.
33:08In large-scale scientific projects
33:10On this stage, you can exchange ideas and share experiences with the world's top experts.
33:16Let's work together to build a community with a shared future for artificial intelligence.
33:38Karachi
33:40Pakistan's largest city
33:4325 kilometers outside the city center
33:46The first overseas unit of China's independently developed third-generation nuclear power technology, Hualong One.
33:51Civil engineering is almost a means of survival
33:55This is Pakistan's largest nuclear power plant.
33:58After completion in 2020
33:59Annual power generation will exceed 18 billion kilowatt-hours
34:03It can completely solve the power supply problem in Karachi and the surrounding area.
34:08Supporting one-third of Pakistan's power shortage
34:14Kamran as a Chinese employee
34:17I worked here for four years.
34:20He transported mostly soil from the construction site.
34:24He and his colleagues make 14 trips a day.
34:27A total of 1.6 million cubic meters of soil were transported away over three years.
34:32This is due to the unique mudstone landform here.
34:35It is a problem that has troubled architects all over the world.
34:41Look
34:41This is mudstone.
34:43The special characteristic of this mudstone is that it is afraid of water.
34:45Once this water enters...
34:47It will expand
34:48The strength will be greatly reduced after expansion.
34:50The mudstone here is very soft.
34:52Especially when encountering water
34:56Seemingly hard mudstone
34:57It becomes extremely soft when it comes into contact with water.
35:02Song Fengwei led the Chinese team
35:05It is necessary to be on such a geological structure
35:07Building the world's largest nuclear power plant bedrock
35:13Safety is the primary standard in the construction of Hualong One.
35:17The completed foundation section is 15 meters deep.
35:21Chinese engineers built a huge reinforced concrete cross here.
35:26Locust
35:27Numerous steel bars are tied together using matching straight threaded connectors.
35:32Together
35:33To ensure a solid foundation
35:38The total amount of steel used in the entire river island reached 95,000 tons.
35:44It uses 10% more than the highest standard for nuclear power plant construction in China.
35:51These steel bars
35:53Enough to build 95 30-story buildings
36:02China's latest kidney-resistant concrete formula has also been used here.
36:08Make the foundation strong enough to withstand earthquakes of magnitude 10 or higher.
36:17While fighting against Niyan
36:19Another major project milestone is approaching.
36:24Prefabrication of the river island dome is underway on the other side of the construction site.
36:31Pakistani worker Du Gang is welding the dome.
36:36Four months later
36:37This is the world's largest and heaviest
36:40But it is also the thinnest river island dome.
36:43The hoisting needs to be done here.
36:47The hoisting plan has been completed.
36:49But will it work?
36:51We still need to wait more than 2,000 kilometers away
36:54Latest news from China
37:01Fuqing, China
37:03The Hualong One dome is exactly the same as the one in Karachi.
37:06Hoisting will begin immediately.
37:10The innovative approach of the twin project
37:13The significance lies in sharing technology.
37:15Advancing in step with global partners in the high-end field of nuclear power
37:23Workers are installing 16 hoisting steel wire ropes, each 39 meters long.
37:29The stress difference between each wire rope
37:31It must be kept below 10%.
37:38The river island dome has a diameter of 46.8 meters.
37:41The thickness is only 6 millimeters
37:44Changes in wind speed and direction
37:46This can easily lead to uneven stress on the 16 steel wire ropes.
37:50Caused dome deformation
37:53Unable to land precisely at the narrowest point of the river island.
37:56Guide groove only 10 mm wide
38:01Project Chief Commander Chen Guocai
38:03At this moment, the most important thing is the change in wind speed.
38:07Once the wind speed exceeds 9.8 meters per second
38:10The dome will be unable to be hoisted.
38:12How's the wind speed now?
38:13The highest it reached was 9.3 meters.
38:15Generally, wind speeds exceeding this are considered to be 9.8 meters.
38:17It exceeds 5 degrees.
38:18Right?
38:19no problem
38:19I feel like I've dropped to 7.3.
38:21May
38:25The wind speed at the seaside is unpredictable.
38:28It can often be 2 meters per second
38:30Reaching 13 meters per second in an instant
38:33This is a severe test for Chinese engineers.
38:40In addition to various lifting components such as steel cables
38:43The total weight of the river island dome during hoisting reached 524.6 tons.
38:50Chief crane operator Yang Jianguo is also on his way to the scene.
38:56Despite having directed the hoisting of thousands of large nuclear power components
39:00But this time, the task is to hoist the dome of the world's largest and heaviest nuclear power plant.
39:06It's still a completely new challenge.
39:13Yang Jianguo needs to work with the other four hoisting commanders on site.
39:17Crane operator
39:18and 45 hoisting workers
39:20200 installation workers
39:22tacit cooperation
39:29Attention everyone!
39:31We're ready to hook.
39:333200 hits, pay attention to hooking.
39:38The moment the dome leaves the ground is the most crucial.
39:43Crane operators must be absolutely precise, down to the second.
39:46At 25%
39:4850%
39:5075%
39:51104 force stages
39:53Gradually increase the tension on the 16 steel wire ropes
39:57And the sway range of the lower opening of the dome will be controlled within 200 millimeters.
40:02Only in this way can we ensure that the dome does not deform.
40:07Captain China
40:08The country is paying attention
40:09Remember to pay attention
40:10We need to load to 75%.
40:19The dome was lifted steadily.
40:23When it reaches a height of 6 meters
40:25After confirming stability
40:27Entering the most crucial hoisting stage
40:31at this time
40:32The crane operator needs to lift the dome 63 meters.
40:36Such a long hoisting distance
40:38It tests the crane operator's steady and accurate speed.
40:46crane movement
40:47The speed of coin driving movement
40:49direction
40:50Working radius and other parameters
40:52All measurements were based on the wind speed of that day.
40:58This was the most tense moment for everyone present.
41:04More than 200 installation workers
41:06We're already waiting at the top of the 43-meter-high river island.
41:24200 installation workers
41:25The force must be balanced.
41:27Otherwise, the lateral torque of the 16 steel wire ropes
41:30It will still cause the dome to deform.
41:33This caused the entire project to collapse.
41:42Some people grabbed the guy ropes
41:44Prevent the dome from swaying from side to side
41:46Some people held onto the dome with their hands.
41:49While rotating, it falls to the appropriate position.
41:57Like fishing
41:58The slightest tremor
41:59All of these factors could cause the fishing hook to miss the school of fish.
42:03At a height of nearly 50 meters
42:06The dome under the influence of the wind
42:08Any uncontrollable shaking
42:10All of these factors could lead to the dome not being accurately aligned.
42:16All the experience comes from the accumulation of three generations of nuclear power workers.
42:22China is the only one in the world
42:24A country that has never stopped building nuclear power plants in the past 30 years
42:29The dome accurately fell into the slot
42:34The suspension bridge was a success.
42:42Data from the Fuqing Monitoring Center
42:45They have now been teleported back to Karachi.
42:48Workers in Karachi are now preparing more dome-shaped piles.
42:53skills
42:56There are more than 5,000 Pakistani workers here.
43:00China has already taught them all the nuclear island safety standards it has set.
43:06These workers were mostly local farmers and fishermen.
43:11Even without a job
43:14They are now among the first nuclear power industry technicians in Karachi.
43:20Safety officer Han Cheng
43:22I really like the Chinese name that the Chinese master gave him.
43:26Today is his first official day on the job.
43:29After training
43:30He has mastered all the safety standards of the nuclear island.
43:35construction site
43:37Han Cheng carefully checked whether the protective measures for each worker were in place.
43:45I am very fortunate
43:46My Chinese leaders have been a great help to me.
43:49I am very grateful to all the Chinese people.
43:55Hualong One technology has been exported to the UK and Argentina.
44:00More than 20 countries have expressed their intention to cooperate.
44:05From infrastructure to technological equipment
44:09China is making continuous contributions to global energy development.
44:22Yibin, Sichuan
44:24A special shale gas convoy is advancing deep into the mountains.
44:32The equipment on the vehicle is specifically designed for shale mining.
44:37Shale gas is a clean energy source that is being vigorously developed globally.
44:43China's shale rock has proven reserves of up to 764.3 billion cubic meters.
44:49World's No. 1
44:52However, most shale deposits are concentrated in the ravine-filled southwest.
44:58mountainous areas
44:59Only a workspace the size of a football field can be created.
45:03The shale deposits here are only 4,600 meters deep on average.
45:08Extremely difficult to mine
45:11China is demonstrating its innovative strength.
45:14Developing new energy sources for humanity presents these new challenges.
45:21Before mining
45:22Engineers have applied the latest technology
45:26Reduced the risk of surface and groundwater pollution
45:31It has achieved zero industrial pollution emissions and reduced waste gas emissions.
45:43Today's main subject of excavation is the Apollo 1 train.
45:48This is the world's smallest pressure train.
45:51It's only the size of a regular four-axle truck.
45:54However, it is the world's first and most powerful single-unit pressure train.
46:00Chinese engineers equipped it with helicopter-grade equipment.
46:045600 horsepower turbocharged engine
46:07High-speed gearboxes that can be used on yachts
46:11The world's largest hydraulic booster pump in the oilfield industry
46:15Each one represents the highest level in its field.
46:22This police station requires 22 pressure trains to work together.
46:27Don't let the fact that Apollo 1 was the smallest of the three missions fool you.
46:29But it is equivalent to the strength of two conventional rolling trains.
46:37High-pressure trains pass through high-pressure pipelines
46:39The inclined sand-slurry was injected deep into the earth's crust at a flow rate of 16 cubic meters per minute.
46:46Liquid lamination
46:48Inclined sand fluid will be forced into the cracks.
46:52A large amount of liquid abrasive was released from the crack.
46:54And it is collected through a specific channel.
47:03Workers are connecting pipes
47:05It is the only channel through which slurry is injected deep into the Earth's crust.
47:09It can withstand a pressure of 140 MPa.
47:17Tighten the connection.
47:19To ensure tight and secure pipe connections
47:22When pressing the train
47:24Even a gap as small as one micrometer can cause liquid to leak.
47:28Pipe burst
47:31Command vehicle parked at the police station
47:33The pressing operation of the liquid abrasive will be completed.
47:37Attention all staff
47:38Attention all staff
47:39YS108-H19-1
47:42The press will begin immediately.
47:44Mixed sand truck plus 400 kills in place
47:47As the command was issued
47:49Sand mixing trucks begin industrial production
47:51The train pump injects liquid into the warning cylinder.
47:56As the pressure represented by the red line gradually increases...
48:01The liquid displacement represented by the green line also gradually increases.
48:05Inclined sand fluid is being steadily injected into the deep formation.
48:13Today's wellhead pressure reached 69.9 MPa.
48:17Approximately equivalent to 700 standard atmospheres
48:21This means that each square centimeter can withstand a weight of approximately 700 kilograms.

48:50Apollo 1 successfully completed its mining mission.
48:53What awaited him was Da Xie Ba Kuai.
49:00Chief Engineer Zhang Shuli led the team
49:02Disassemble more than 2,000 parts one by one
49:07This is how to obtain raw data.
49:09Finding defects and improving performance is an unavoidable step.
49:16Turbo engine
49:17piston pump and ultra-high speed gearbox
49:20These three key components
49:22Condition after 300 hours of operation
49:26This is what engineers are most concerned about.
49:36Planetary gears are the core component of a gearbox.
49:45The engineers set the length of each ruler to 20 centimeters.
49:52The tilt angle is designed to be 24 degrees.
49:56The upper and lower parts combine to form a herringbone gear.
50:00This is currently the structure with the strongest load-bearing capacity.
50:05The final gear assembly
50:06Located at the center is the sun wheel.
50:09This causes the three outer planetary gears to rotate.
50:13The planetary wheel and the sun wheel should be closely aligned.
50:16Only then can the forces be balanced.
50:18Instantly reduce engine speed and increase torque
50:21Provide power
50:27Technological breakthroughs like this
50:29There are more than 50 other things related to Apollo.
50:33Behind each item
50:34They all drive the upgrading of an industry.
50:46Workers are disassembling the Apollo 1 injection pump.
50:50Place in the testing station
50:52Restart
50:59Engineer Zhu Xiangying
51:00In a unique way
51:02Test his fatigue tolerance after working under high pressure for 300 hours.
51:11Use a wrench to listen to the operation of each component in the injection pump.
51:16This is a special skill that Zhu Xiangying honed over ten years.
51:21Vibration of mechanical operation
51:22It will be transmitted through the metal wrench
51:25Forming regular sound waves
51:28Zhu Xiangying is able to detect changes in sound waves
51:30Determine whether each component in the massive collapse is functioning properly.
51:37I can hear the door clicking shut.
51:40The sound of the ruler striking back and forth.
51:42The friction sound between the small end of the connecting rod and the bearing plate.
51:44There was also the sound of lubricating oil flowing at high speed.
51:46If it doesn't run smoothly
51:48It will make an unpleasant squeaking sound.
51:50Or the clanging sound of impact.
51:57These are just some of the ingenious techniques.
52:01Besides self-testing
52:02The core is to gain the approval of others.
52:12Apollo 2 is undergoing final assembly.
52:15Pressure equipment produced by this Chinese company
52:19It has gained recognition from American counterparts.
52:24Today is the delivery day.
52:27American businessman Richard Clinton came to pick up the car.
52:33His home state of Texas
52:35It is the first in the world to achieve
52:37Shale tool commercial development areas
52:43After global comparison
52:45They ultimately chose Chinese energy equipment.
52:50Richard Clinton wanted to personally test the power of the pressurized train.
53:01As pressure continues to increase
53:03The output power of the Apollo 2 train was continuously increasing.
53:07This is equivalent to the operational capacity of two conventional rolling mill trains.
53:12High power
53:13Long homework time
53:14Low energy consumption
53:16Apollo 2 fully met the requirements.
53:23Technology determines the future of energy
53:26Technology Creates the Energy of the Future
53:30This is a day worth celebrating.
53:33China is ready
