[Three rain valve to recommend the star product - Mechanical seal] Introduction: 1. First seal selection should be clear basis: first job within the autoclave, and the second is the nature of the work material. There is also a device that is operating temperature. 2. it is necessary to clear its non-stainless steel reactor vessel types used in sealed: The sealed reactor known as kettle has two types of seal mechanical seal, packing H8-48 first is mechanical seal, and the second is a mechanical seal Mechanical seals are divided into single letters (ie, single mechanical seal) and dual mechanical seal (ie, double mechanical seal), stand-alone water jacket also includes a full closure, double mechanical seal mechanical seal is more messy, in addition to water jacket ( it is necessary to have a circulating cooling water), but also includes supporting bracket, balance cans. Elastic element and locking ring: they constitute the load, compensation and buffering mechanism H8-65 mechanical seal, to ensure the mechanical seal fitting end face after installation; timely compensation when worn; in by vibration, ran a dampening effect. The elastic member may be a spring, bellows, wave springs and the like. Axial and radial locking ring for the elastic element positioning H8-60 mechanical seal, usually both transmitting torque or torque to overcome functions. [Three rain valve to recommend the star product - Mechanical seal] Introduction: the advantages and disadvantages of various seal: packing offer the cheapest printing chemical mechanical seals, but only the most general use of appropriate conditions and materials; moderate single seal quote GM can use in most conditions; double mechanical seals offer the most expensive, but in the harsh operating conditions it is necessary to use. Secondary seal; play a secondary seal, the secondary seal ring divided compensation and non-compensation of ring seals. It can be an O-ring, V-ring, wedge ring, rectangular ring, etc., used to seal the shaft seal and mechanical seal, mechanical seal and housing.
