Source Title: The Shenzhou 13 crew successfully settled in Tiangong Great Wall Lubricant to guarantee full marks and docking

At 0:23 on October 16th, the Shenzhou 13 manned spacecraft was successfully launched into space at the Jiuquan Satellite Launch Center. This mission followed the “autonomous rapid rendezvous and docking mode” used by Shenzhou 12, and only used after it was put into orbit. Within a few hours, it successfully completed the docking with the Tianhe core module of the Tiangong space station and delivered the three astronauts “Zhai Zhigang, Wang Yaping, and Ye Guangfu” to the Tiangong space station, officially starting a six-month space life.

The Shenzhou 13 manned spacecraft and the Tiangong Space Station have an orbital speed of 7.8 km/s, which is more than 80 times the speed of the high-speed rail, but can complete the rapid docking with millimeter-level accuracy. Compared with other countries that require several days to complete the docking, Shenzhou Ten The efficiency and accuracy of No. 3 can be seen. In fact, there are too many black technologies related to China’s manned spaceflight, and it is even enough to compile a book of “One Hundred Thousand Whys.” We must know that behind China’s aerospace is the comprehensive support of a great country’s huge industrial system. For example, the “micron-level high-clean lubrication” technology developed by Sinopec Great Wall Lubricant has played a key role in this docking.

The crown jewel in the lubrication industry for manned spaceflight

The Shenzhou 13 spacecraft successfully docked with the Tiangong space station, which once again focused the attention of the Chinese people on China’s manned space station project. The fruitful achievements of China’s aerospace industry and the astronauts’ work on the space station have become talks that everyone talks about. It just so happens that reports about a certain space station’s frequent failures and disordered environment are also common in newspapers, forming a sharp contrast with very contrasting effects. This fully shows that the aerospace industry is a manifestation of a country’s comprehensive national strength and requires the support of a huge industrial system. , Every link is a representative of the world’s most advanced technology. Therefore, there are many countries that can launch artificial satellites, and there are only a handful of countries that have independently completed manned spaceflight, especially the construction of space stations.

Back to ten years ago, on November 3, 2011, the whole country was in joy, because on this day, “Tiangong 1” and Shenzhou 8 spacecraft rendezvous and docked, and China became the third after the United States and the Soviet Union to master this core black technology. The country has also paved the way for the construction of China’s space station. In fact, the entire docking technology has been independently developed by China. It is required that the operation of all sub-systems such as navigation, braking, and control of the spacecraft and the space station need to exceed the mechanical clock and reach a very high level of precision and stability to ensure that it is foolproof.

Great Wall Lubricants has previously successfully provided high-quality lubrication support from the Dongfanghong-1 satellite to the Chang’e lunar exploration project and the Shenzhou series spacecraft. In this Tiangong docking project, in order to meet the nearly harsh requirements of the Tiangong system for lubrication, Great Wall Lubricant has carried out a thorough upgrade of the lubricant plot, using advanced molecular distillation technology to finely separate the base oil to produce Micron-level high-cleaning performance special lubricants ensure that the entire docking action is generally smooth. It is worth mentioning that the large temperature difference and strong radiation in outer space can easily damage the chemical structure of the oil. The “Tiangong-1” is designed to operate for only two years, so the life expectancy of lubricants is relatively low, but at that time, Great Wall Lubrication Oil has taken into account the needs of the long-term development of China’s aerospace, and forward-looking positioning of the lubricating oil life index to meet the “high standard” of 50,000 hours of continuous operation, not only far exceeds the requirements of the “Tiangong-1”, but also for today’s “Tiangong” The long-term service of No. 2 in orbit has laid a solid foundation for science and technology. In the words of Dr. Chunhui Zhang, deputy general manager of Sinopec Great Wall Lubricant Company, “Only one refill is required, and there is no need to change the oil during the period.” This promise seems to be light and windy, but it comes from Sinopec Great Wall Lubricant Service Aerospace nearly 70 years. Carry the confidence and self-confidence of precipitation.

To escort major powers to witness the great era of renaissance

Behind the great achievements of mankind, there are always one or more great countries.

There is no doubt that the manned space project is the epitome of national power. From aerospace measurement and control, launch vehicle engines, life support systems, heaven and earth return systems to precision gyroscopes, motion mechanisms, sealing systems, energy systems… the black technology needed for manned spaceflight is probably not just a few pages to describe in detail. Lubricating oil is one of the key technologies that is not conspicuous but indispensable in this huge “list”. Thoughts have been extended from aerospace engineering. Nuclear power plants, large hydropower stations, ocean-going ships, large transport aircraft, high-speed railways…Almost all of the major powers, high-end equipment and key projects that Chinese people can imagine, precision lubrication has its irreplaceable value. .

Who can imagine that for the Fuxing high-speed rail with a speed of 350 kilometers per hour, the gearbox lubricant needs to ensure that the continuous driving of 600,000 kilometers is trouble-free, and at the same time, it must also consider the impact of various unfavorable factors caused by the complex landforms of the high-speed rail and the temperature difference between north and south. The most important thing is that because China’s high-speed rail is leading the world, the lubricant market does not yet have shelf products that can be matched. The development and quality control capabilities of Sinopec Great Wall lubricants service for China Aerospace Refining make it possible to support Fuxing.

Who would know that in the Baihetan Hydropower Station, which brought the world’s hydropower into the “millions of single-unit era”, a single 1 million kilowatt water turbine unit has a rotor weight close to 2,000 tons. After power generation is started, the rotor will always keep running at high speed. Lubricating such a “big guy” is self-evident to the test of lubricant performance. At present, the 16 units of Baihetan Hydropower Station all use the “Great Wall TSA46 (A-Grade) Turbine Oil” independently developed by Great Wall Lubricants, and they are operating in good condition…

Therefore, as long as you have a little understanding of the demand scenarios for precision lubrication and high-end lubrication, it is not difficult to find that it is not an exaggeration to call manned spaceflight supporting lubrication the jewel in the lubricating grease industry. It is Great Wall Lubricants, which has developed more than 50 aerospace lubrication products in 7 categories, and has almost witnessed the highlight moment of every milestone in China’s aerospace. With a “100 points” score of 0 lubrication accidents, it has escorted nearly 400 launch missions. , To grow into the most trustworthy comrade-in-arms and partner of China’s aerospace industry. The stories of Great Wall Lubricants serving the major powers of the country are even more numerous.

From long-life lubrication, environmental protection lubrication to outer space lubrication, we can find Great Wall Lubricant in almost every flash of the great rejuvenation era. It is the millions of successful companies that are like Great Wall Lubricants that enable Made in China to overcome all difficulties and strive for self-improvement, forming the core of the power of the era of national rejuvenation.
