 Mechanical seal (mechanical seal) is defined as at least one rotation axis perpendicular to the face in the fluid pressure and elastic compensation mechanism (or magnetic), and supporting the role of keeping under seal with the paste composition of the combined sliding and prevent fluid leakage device. Elastic loading mechanism and the secondary seal is a metallic bellows mechanical seal which we call metal bellows seal. In the light seals, there are supporting the use of rubber bellows for sealing, rubber bellows stretch limited, generally need to meet the load supported by elastic springs. 
 "Mechanical seal" usually been referred to as "mechanical seal." 
 Mechanical seal consists of: 
 There are four main parts. a. The main parts: ring and stationary ring. b. Auxiliary Seal: Seal (with O-, X-shaped, U-shaped, wedge-shaped, rectangular flexible graphite, PTFE-coated rubber O-ring, etc.). c. elastic compensation mechanism: spring, push the ring. d. Transmission Parts: Kei seat and key or playing a variety of screws. Details Come: http://www.qb0595.com
