[Three rain valve to recommend the star product - Mechanical seal] Description: diverse architecture mechanical seal, commonly used structure generally includes the following components: 1. The locking device (locking screw) 2. 3. resilient locking ring element (spring) 4. transmission mechanism (drive sleeve) 5. Central 6. Friction compensation 7 secondary seal (O-ring) 8. Non-compensation 1. Compensation ring ring ring with non-compensation: Compensation ring is an axial compensation capability sealing ring, it can be rotated ring (ring), it can be a non-rotating ring (stationary ring); seal ring seal H76N-33 machine does not have a non-compensated ring is axial compensation capability, the same can be rotating ring (moving ring) H76N-25 mechanical seal, or non-rotating ring (stationary ring) 2 friction: the ring at the top of the compensation and non-compensation ring inlaid with a pair of seal face, the main seal from the mechanical seal. Under normal circumstances compensate narrow ring of soft material, end; uncompensated manufacturing ring with a hard material, end wider. [Three rain valve to recommend the star product - Mechanical seal] Introduction: mechanical seal classify a variety of ways. According to the number of the seal faces: two single-acting and double-acting (multiple-acting) by way of pressure to uninstall: divided into balanced and unbalanced by the elastic component count: two large springs (single spring), a small spring (multi-spring) , plate spring form of the structure: divided into bulk and cartridge type according to the installation location: divided into built-in and external mounted by movement: rotary and static divided by media leaks direction: into the inner stream and outflow type by application equipment: water pump into use, chemical pumps, slurry with, kettle, etc. H76N-40 _ Yiyang mechanical seal mechanical seal mechanical seal _H76N selected three rain provided by Valve Co., Ltd.
