Hydraulic pump seals
The hydraulic pump seals to prevent leakage of the hydraulic pump working medium as well as to prevent foreign matter from entering institutions of hydraulic components and hydraulic systems.
Hydraulic pump seals as auxiliary hydraulic equipment parts, its role can not be discounted.
Hydraulic pump seals need to consider their work environment, so the selection of high voltage, resistance to chemical attack hulled oil seal lip at the selection of a modified nitrile rubber, with strong oil resistance, abrasion resistance, heat resistance, corrosion and so on.
The sealing material is usually in the hydraulic system of the nitrile rubber, fluorine rubber or the like.
The difference is mainly in:
1. The coefficient of friction of the material;
2. Temperature performance;
3. Withstand performance;
4. Hydrolysis resistance.
A coefficient of friction of the nitrile rubber is generally 1.3-1.5, the friction coefficient of the fluorine-containing rubber is generally in the 1.0-1.3
