Magnetic pump manufacturers introduce magnetic pump without leakage method

No leakage is always thought of in chemical machinery and equipment, and it is this kind of regulation that promotes the use of magnetic pumps. As everyone knows, there is a long way to go without leaks, such as the life cycle of the magnetic pump protective cover, the pitting problem of the material, and the credibility of the static seal.

1. Magnetic pump sealing method For static sealing, generally only two methods of rubber sealing ring and sealing ring are available, and the sealing ring is most widely used by O-ring; for dynamic sealing, chemical pump is rarely used for packing sealing, The machine seal is dominant. The machine seal has a single milling surface and a double milling surface, a balanced type and an unbalanced type. The equalization type is suitable for the sealing of the rolling material (generally the water pressure exceeds 1.0MPA), and the double milling mechanical seal is the first. For high temperature, easy crystal, viscosity, particle and its harmful evaporation, double milling mechanical seal needs to introduce isolation liquid into the sealed mouth, the water pressure is generally higher than the material water pressure 0.07 ~ 0.1MPA.

2, magnetic pump rubber seals chemical industry magnetic pump static seal material is generally selected fluorine rubber, the common situation is to use polytetrafluoroethylene material; machine seal dynamic ring material is more important, not hard alloy is the most suitable for cemented carbide The price is not only high, the two have no strength difference and are not scientific, so it is most suitable according to the double standard of material characteristics.
