Chemical Pump Usage: Chemical pumps are widely used in chemical, petroleum, metallurgy, light industry, synthetic fiber, environmental protection, food, medicine and other departments, to improve product quality, reduce run, run, drip, leak, prevent pollution and improve the environment, play significant role.
Chemical pump seal state two high side note:
1, the sealing material
Chemical pump static sealing materials commonly used Viton, PTFE used under special circumstances materials; mechanical
Glass-to-metal seals ring material movement configuration is more critical, and not on the best carbide cemented carbide, high prices on the one hand, two who did not have the hardness difference is unreasonable, so the most
Good dielectric characteristics under different treatment.
2, seal the form
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 and a 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
Hermetically sealed connectors is mainly used for high temperature, easy to crystallize, the viscosity, containing particles and toxic volatile media, double end mechanical seal shall be sealed chamber spacer fluid injected, the pressure is generally higher than the medium pressure
0.07 ~ 0.1MPa.
