Piston rod seals should be considered in the purchase of factors

As we all know, the piston rod seal refers to the seal between the piston rod and the cylinder head to prevent fluid from leaking from the inside of the hydraulic cylinder to the outside. It is one of the most demanding applications in fluid power equipment. The leakage of the piston rod seal will affect the performance of the entire machine equipment. And life, while in severe cases, it will cause environmental problems. In order to meet the needs of the industry for practical sealing solutions, piston rod seals are required to act evenly on the sealing area, have good medium compatibility, high and low temperature resistance, wear resistance, anti-clearance extrusion, low friction, compact structure and Easy to install.

In order to meet the needs of the industry for practical sealing solutions, piston rod seals are required to act evenly on the sealing area, have good medium compatibility, high and low temperature resistance, wear resistance, anti-clearance extrusion, low friction, compact structure and Easy to install.

With the development of science, technology and industry,

Piston rod sealThe design of parts is becoming more and more diversified, but there is often a gap between technical design and processing technology. In order to be able to make their own purchase more satisfactory products, for the current market launch of many piston rod seals, in the purchase of the time or to pay attention to a lot of details and rules.

The importance of piston rod seals and their limit values generally depend on the requirements of special purposes. Generally, the working temperature, viscosity of working medium, working pressure, allowable leakage, movement speed of piston rod, starting friction of piston rod, and requirements of sealing ring on piston rod fit tolerance and groove size of piston rod should be taken into account when selecting. Then when buying in the market, it is necessary to master the quality grade and process of each sealing ring, and grasp the technical characteristics. The quality coefficient is an aspect that every customer must carefully compare.

In addition, the most important thing for the piston rod sealing structure and the sealing ring is to choose according to the actual situation. The model size is also a very important aspect. The model size should be matched completely, and it needs to be carefully compared in the analysis process.
