[Three rain valve to recommend the star product - Mechanical seal] mechanical seal (mechanical seal) is defined by at least one axis of rotation perpendicular to the face of the compensation mechanism under fluid pressure and elasticity (or magnetic) role and secondary seal fluid leakage with holding means affixed under the combined constituted prevent relative sliding. Elastic loading mechanism and secondary seal is metallic bellows mechanical seal we called metal bellows seal. In light seal H76-45 mechanical seals, as well as the use of rubber bellows mechanical seal as secondary seal, rubber bellows stretch limited, generally need to be supplemented to meet the load spring stretch. "Mechanical seal" that is often referred to as "mechanical seal." [Three rain valve to recommend the star product - Mechanical seal] Introduction: principles outlined by a pair of mechanical seal is cartridge mechanical seal or several vertical axis relative to the end face of elastic sliding in fluid pressure and compensation mechanism ( under or magnetic) merged with the role of maintaining the secondary seal affixed to achieve the seal device leakage resistance. Commonly used by mechanical seal stationary ring (stationary ring) a rotating ring (ring) 2, the elastic element 3, spring seat 4, 5 set screws, rotating ring secondary seal 6, 8 and stationary ring seals and other auxiliary elements composition, anti-rotation pin 7 is fixed on a stationary ring gland 9 to prevent rotation. Rotating ring and stationary ring often also based on whether they have the ability to compensate axial ring and called compensation or compensation ring.
