Blocking fluid in mechanical seal system:
Blocking fluid means that in the double-end face seal mechanical seal, fluid is introduced from the outside, and its fluid pressure is higher than the pressure of the sealed medium, which plays a role of blocking and isolating. In a blocked fluid system, the fluid is divided into liquid and gas. In the past, liquid was often used to block liquid or gas, that is, liquid-sealed liquid or liquid-sealed gas. In order to save the huge blocking liquid system, the blocking gas is used to block the liquid or gas, that is, the gas-sealed liquid or the gas-sealed gas. The spiral groove gas seal and the blocking gas can be used in the system, and the floating sleeve and the blocking gas can be used to block cold. Gas or liquid. In addition, to achieve good blockage, zero leakage or zero escape, the pressure difference between the blocked fluid and the sealed medium needs to be kept within a certain range. Therefore, in the system, a differential pressure control system to control the pressure of the blocked fluid is also required. Sand mill mechanical seal 　　1083.html,
