Principles outlined edited by a pair of mechanical seal is cartridge mechanical seal or several vertical axis relative to the end face of sliding under the pressure of the fluid and elastic (or magnetic) compensation mechanism of action to maintain the seal affixed to merge with auxiliary achieve stop leak The shaft sealing device. 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 65-250 (I) B mechanical seals, anti-rotation pin 7 is fixed on a stationary ring gland 9 to prevent rotation. One of the basic components of mechanical rotating ring and stationary ring often also based on whether they have the ability to compensate axial ring and called compensation or compensation ring on how to choose the pump mechanical seal is a precision mechanical seals, the structure is more complex 65-250 (I) mechanical seals, a variety of pumps, reaction synthesis reactor, turbine compressors, submersible motors and other key components of the device. Sealing performance and service life depends on many factors 65-250 (I) A mechanical seal, such as the accuracy of selection, the machine, the correct installation and so on. First, the selection of the method according to the working condition of the mechanical seal and the different nature of the medium, there is high temperature, low temperature mechanical seals, high pressure, corrosion-resistant mechanical seals, mechanical seals and anti-particle medium mechanical seals adapt easily vaporized light hydrocarbons media etc., should be selected mechanical seal types and materials of different structures depending on the use. Selection of the main parameters are: the seal chamber pressure (mpa), fluid temperature (℃), working speed (m / s), the characteristics of the fluid and the installation space effectively sealed. The basic principles of selection are: mechanical seals _65-315 (I) water pump mechanical seal _ Shi Yuan (certified merchants) provided by Anguo City Pump Co., Ltd. Shi Yuan.
