Sealing components are the most important devices for current and future mechanical and industrial equipment. Sealing components have two main functions. One is to prevent leakage of grease, water and gases; the other is to protect against dust.
1. Lip Optimization: under peripheral pressure, the lip and groove surface fit more closely, and the higher the pressure, the better the lip sealing.
2. The fan-shaped supporters, in the premise of increasing the strength of the sealing ring, can shrink and expand in radial direction with the sealing ring.
How to make a good oil seal?
Three factors affect the production of oil seals.
How to get useful oil seals?
You need to know the working environment.
Housing, shaft and width dimensions
Operating temperature, pressure and physical environment
(heat, ozone, chemical, etc.)
