The new sealing method of piston rod seal will replace the conventional sealing method
2020-03-03
Piston rod sealing is a difficult task in all hydraulic components. If the sealing work is not done well, or when the piston rod seal is damaged, oil leakage may occur, which will affect the normal operation of the piston rod, and even pay a lot of work to replace them and bear the loss of shutdown. Because of the leakage of hydraulic oil, this work is quite expensive. Therefore, its perfection is a problem that people are very concerned about.

The difference between piston rod seal and piston seal should not be confused
2020-03-03
There is a word difference between the piston rod seal and the piston seal, but the effect is very different. The difference between the piston seal and the piston rod seal is also a necessary knowledge of the piston rod. Before understanding this problem, in order to facilitate understanding, we first look at what is the piston and the piston rod.

Application of ultra-high pressure seal
2020-03-01
Ultra-high pressure seals are also divided into static seals and dynamic seals. With the development of sealing technology, new materials, new structures and special processes have been developed. Products with high technical content, ultra-high pressure resistance, long life, low friction, and no leakage. If according to the composition of the hydraulic system, the ultra-high pressure seal is divided into pipeline seal and hydraulic component seal, hydraulic cylinder, hydraulic motor, hydraulic pump, hydraulic valve and so on are common in hydraulic components.

The importance of ultra-high pressure seals for future development
2020-02-28
Ultra-high pressure sealing problem is a very difficult problem in the industry, especially for pressure vessels and other products with high safety requirements, in addition to realizing the design function, but also pay attention to safety. In recent years, mechanical and electrical products at home and abroad are generally developing towards high pressure, high speed and high performance. Some products require hydraulic system pressure to exceed 80MPa or even reach 200MPa. This requires matching seals with ultra-high pressure resistance, long life and other properties.

How to judge the service life of ultra-high pressure sealing ring
2020-02-27
The technical level, quality and performance of ultra-high pressure sealing ring directly affect the quality and operation reliability of the supporting host products. Especially in the production process, the medium has flammable, explosive, toxic and corrosive properties. A large number of leaks not only endanger the safety of the device, but also pollute the environment in a large range, which puts forward higher requirements for the sealing of production equipment, therefore, the correct use and accurate judgment of its life is also the focus of the work.

What are the factors that affect the performance of ultra-high pressure seals
2020-02-26
Ultra-high pressure sealing ring is widely recognized because of its advantages of low leakage and long life. With the rapid development of national economic construction, it has made continuous progress, and various institutions have appeared according to different working conditions. However, no matter what kind of structure, there is a sealing end face (friction surface) composed of a moving ring and a static ring, a buffer compensation mechanism, and an auxiliary seal and a transmission mechanism.
