Chemical pump mechanical seal options introduced

No leakage is always the pursuit of chemical equipment , it is this requirement led to the application of magnetic pump expanding . However, truly no leakage is still a long way to go, such as magnetic pump containment shell life issues, pitting the material problems of static trailer seals sealing reliability issues and so on. Now on some basic aspects of seal briefly as follows:
A seal forms for static sealing , it is usually only two forms of gaskets and seals , and O-ring seals Youyi most widely ; For dynamic sealing , chemical pumps rarely used packing seal, mechanical seal based , mechanical seals have single face and double face , balanced and unbalanced type of points , balanced for high pressure sealing medium ( usually refers to pressure greater than 1.0MPA), double end mechanical seal is mainly used for high temperature , easy to crystallize , there viscosity, containing particles and toxic volatile media , double end mechanical seal should insulating liquid is injected into the sealed chamber , the pressure is generally higher than the medium pressure 0.07 ~ 0.1MPA.
2 , the sealing material chemical magnetic pump static sealing materials commonly used Viton, PTFE used under special circumstances materials ; mechanical seal ring material movement configuration is more critical , and not on the best carbide cemented carbide ,vehicle seals high prices on the one hand , the hardness difference between the two is not too unreasonable , so it is best treated differently according to media characteristics .
