What are the influencing factors of seals

Seals play a vital role in the integrity of hydraulic and pneumatic components. If the seals of a hydraulic and pneumatic component product are not up to standard, then this hydraulic and pneumatic component product is not a good product. Therefore, in order to avoid this situation, we need to understand the factors that affect the product.

1. Pressure is an important factor affecting the quality of the product. The level of pressure and the length of the pressure cycle change have a great impact on product damage (such as extrusion). The higher the pressure, the greater the impact of other factors on the performance of the product, such as temperature, speed, material of the product, the gap between the piston and the cylinder, and the gap between the piston and the cylinder head.

2. Temperature is the same as friction. It is difficult to describe the higher service temperature and lower service temperature of a product material, because this is the result of the comprehensive influence of a series of factors. For the working temperature of the piston and the piston rod are different, they should be selected differently.

3. Product surface roughness, surface characteristics, pressure, medium, temperature, material, type of seal and movement speed are all influencing factors.

4. Surface treatment. Experience shows that the characteristics of the surface of the cylinder piston and piston rod have a great influence on the life of the product. Surface properties are often defined by the value of surface roughness RA, which is the arithmetic mean of the absolute value of the surface shape deviation from the center line. However, these values ​​cannot fully represent the influence of the surface condition on the product, because even under the same roughness, different surface shape features can cause different degrees of wear on the product.

To sum up, there are many factors that affect seals, which requires us to take corresponding countermeasures and preventive measures after detailed understanding to avoid affecting the use of equipment and causing losses to enterprises.
