[Three rain valve to recommend the star product - Mechanical seal] Introduction: basic concepts of mechanical seals: mechanical seal means the action by at least one end face perpendicular to the axis of rotation of the compensation mechanism in fluid pressure and elasticity (or magnetic) of By means of fluid leakage at the secondary seal and mating holding stick combined constituted prevent relative sliding. Compensation secondary seal ring called bellows mechanical seal for metal bellows. 2, the mechanical seal components: There are four main components. a primary seal: ring and stationary ring. b auxiliary seals: seals. c pressing pieces: spring, pushing the ring. d transmission parts: Kei seat shells and keys or screws. [Three rain valve to recommend the star product - Mechanical seal] Introduction: The correct assembly tolerances M74-160 mechanical seal, for the installation of the mechanical seal is necessary, the shaft (sleeve) must have a suitable surface roughness and correct size, but provide little tolerance data M74-110 manufacturer of mechanical seal, these data are critical in terms of installation. Compensation and non-compensation ring ring: compensation ring is sealing ring with axial compensation capability, which can be rotated ring (ring) M74-140 mechanical seal can also be a non-rotating ring (stationary ring); non-compensation does not have the ring ability to compensate axial sealing ring, the same can be rotating ring (ring), or non-rotating ring (stationary ring) M74-120 mechanical seal mechanical seal selection Tianjin _ Rain (certified) _ Heyuan mechanical seal from Tianjin Valve Co., Ltd. offers three rain.
