hardware flow control. It is an ideal choice in the field of industrial automation.
The research and development, manufacturing and sales of high-end bearing steel
are basically monopolized by the world”s bearing giants Timken
of the United States and SKF of Sweden. In the past few years, they established bases
in Yantai and Jinan, Shandong Province, purchased low-end materials from China,
used their core technologies to make high-end bearings, and sold them to the Chinese
market at ten times the price. Adding rare earths during the steelmaking process can make
the original high-quality steel “stronger”. But how to add it is the core secret of the world”s bearing giants.
High-pressure plunger pump 14 “High-pressure plunger pump, a thorn in the throat of China”s
equipment manufacturing industry” (Science and Technology Daily, May 28)
The hydraulic system is one of the key components in the equipment manufacturing industry.
In all engineering fields and wherever there is mechanical equipment, the hydraulic system
is inseparable. The high-pressure plunger pump is the core component of high-end hydraulic equipment and is
called the “heart” of the hydraulic system. The scale of China”s
hydraulic industry has become the second in the world in 2017, but the industry is large but not strong,
especially high-pressure plunger pumps with rated pressures above 35MPa, more than 90% of which rely on imports.
Compared with foreign brands, domestically produced hydraulic piston pumps have a large gap in
technological advancement, working reliability, service life, variable mechanism control function and dynamic
and static performance indicators. They are basically equivalent to those produced abroad in the early 1990s. level.
Aeronautical Design Software 15″Aviation software is in embarrassment, and domestic aircraft design is
under a “tightening curse”” (Science and Technology Daily, May 30)
Since the 1980s, the world”s aviation industry has entered a new stage of digital design, and has now reached a level
of dependence that makes it impossible to design without software. Designing an aircraft requires at least a dozen types
of professional software, all of which are products from European and American countries. Domestic design units not only
have to invest huge sums of money to purchase software, but also wear steel rings on their heads. Once the “spell” is recited, the
entire aviation industry will be paralyzed. According to media reports, when the J-10 aircraft was designed, the entire metal components
of the main load-bearing structure of the main landing gear were commissioned to be manufactured abroad. But after it was built, there was
a problem with the retraction and retraction of the landing gear. There was a 5 mm error, so we had to re-order it. Just this small
error affected the delay of the J-10″s first flight by eight or nine months. Without full digital software support, any slight error may become
a nightmare for the manufacturing industry.
