Select configuration chemical pump mechanical seal (2)

no leakage is always the pursuit of chemical equipment, is expanding the application of magnetic pump. But is there really no leakage is still a long way to go, isolation sets of life issues such as magnetic pump, pitting the important matters, problems, so the reliability of static sealing. Enclosed area is briefly some of the basic situation is as follows:
seal form, usually only two gaskets and seals and type O sealing ring and in the most widely used static seal; Dynamic seal, chemical pump packing seal is scarcely used, mainly by mechanical seal, mechanical seal has single-sided and double-sided, the type of equilibrium and non equilibrium, high pressure medium ( Usually greater than. MPa pressure greater) , the balance of double mechanical seal, it is mainly used for sealing the high temperature viscosity and crystallization, and the particles and volatile toxic medium, the double mechanical seal cavity should be incorporated into the spacer fluid sealing, pressure is generally higher than that of medium pressure. 吗? 。 The MPa is higher.
, sealing materials, chemical raw materials, static sealing magnetic pump commonly used fluorine rubber, special circumstances, it USES the ptfe material, mechanical seal ring material configuration is relatively static key, not cemented carbide for the best, the cemented carbide with high price on the one hand, there is no reason for the difference between the hardness, so the best function of discrimination, according to the media.
