Chemical pump mechanical seal

Chemical pump is a new type of energy-saving equipment, its design needs to strictly comply with international standards, these products are characterized by a rational layout, the user experience is good. Nowadays, these kinds of products have great significance in industrial, urban water supply, drainage and other aspects. In the meantime, chemical pump related topics have also drawn increasing attention. For example, "Chemical Pump Mechanical Seals" recently received great attention. Chemical pump mechanical seal leak-free is the eternal pursuit of chemical equipment, it is this requirement contributed to the growing use of chemical pumps. However, there is still a long way to go without leakage, for example, the life span of the chemical pump isolation sleeve, the problem of pitting corrosion of the material, the reliability of the static seal, and the like. Now on the sealing of some of the basic situation is briefly described as follows: 1, the sealing form For the static seal, usually only two forms of seals and seals, and O-ring seal again the most widely used; for dynamic seals, chemical Pump seldom used packing seal to mechanical seal-based, mechanical seal and single-sided and double-sided, balanced and unbalanced type, balanced type for high pressure medium seal, double-sided machine seal is mainly used for high temperature, Easy to crystallize, viscous, containing particles and toxic volatile medium, double seal should be injected into the sealed chamber isolation liquid, the pressure is generally higher than the medium pressure 0.07 ~ 0.1MPa. 2, sealing material Chemical magnetic pump static sealing materials generally use fluorine rubber, special circumstances only use PTFE material; mechanical seal ring static material configuration is more critical, not cemented carbide on the best cemented carbide, high price On the one hand, the difference between the two hardness is not reasonable, so it is best to distinguish between media characteristics. In summary, we can initially understand the chemical pump mechanical seal information. Understanding such information is of paramount importance both for the use of chemical pumps and for the protection of chemical pumps and should attract the user's attention.
