Characteristics and Application of Piston Rod Seal
Author:
With the continuous development of science and technology and industry of the times, the requirements for reciprocating motion are also constantly improved. In our development of some construction industry and car body industry, we will use them.Piston rod sealIts existence is extremely important, thatPiston rod sealWhat are its characteristics and what applications do they have?
Piston rod sealRing It is a kind of sealing element that can be divided into Glea ring and Stern seal. It is a symmetrical cross-section slip ring with no filling material. In addition, it is a combined seal formed by combining a circular sealing ring with an elastic element,Piston rod sealIt can also be used as a one-way seal.
Piston rod sealThere are many functions of the piece, including using a combined seal, and then generating prestress from the circle shape, and then playing a compensation role for the initial state and the working state, and then because of its small friction, under pressure loadPiston rod sealHas a very high pressure resistance and compression stability, it has a very good anti extrusion performance,Piston rod sealThe leak is small,Piston rod sealIt also has the function of pumping,Piston rod sealThe form does not produce resistance to friction and does not lead to premature wear of the sealing lip. andPiston rod sealThe wear resistance is very high and will not cause the oil system to crawl and other characteristics.
The combination of the hydraulic piston rod is the structure of the seal. It is the main sealing ring made of PTFE filler, and the other is a circular elastic seal, which plays the role of a secondary seal.
Piston rod sealThere are many combination applications, including avoiding mutual contact between metals, it also greatly improves the bearing capacity and can withstand a certain lateral force, and becausePiston rod sealThe friction of the assembly is very small, so it is suitable for high-pressure and high-speed systems.
