Basic concepts of mechanical seals (seal): vibration motor [1] A mechanical seal refers to a device that prevents fluid leakage, consisting of at least one pair of end faces perpendicular to the rotating shaft. These end faces are kept in contact and slide relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, as well as with the cooperation of auxiliary seals. The elastic loading mechanism and auxiliary seals of metallic bellows in mechanical seals are called metal bellows seals. In lightweight seals, rubber bellows are also used as auxiliary seals. Due to the limited elasticity of rubber bellows, springs are generally required to meet the loading elastic force.
The term "mechanical seal" is commonly abbreviated as "seal".
Composition of a mechanical seal (with emphasis on the following four types of components):
a. Main components: rotating ring and stationary ring.
b. Auxiliary sealing parts: gaskets (including O-rings, X-rings, U-shaped, wedge-shaped, rectangular flexible graphite, PTFE-covered rubber O-rings, etc.).
c. Elastic compensation mechanism: springs, thrust rings, vibrating screens.
d. Drive components: spring seats and keys or various screws.
