Chemical pump uses: 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, improve the environment, play Great effect. How does it achieve high seal? This question can be explained from the following two aspects. 1. Sealing 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 pumps rarely use packing seal, the main mechanical seal , Mechanical seal has a single end and double end, balanced and unbalanced type, balanced type for high pressure medium seal (usually refers to the pressure greater than 1.0MPa), double end machine seal is mainly used for high temperature, easy to crystallize, there is Viscosity, containing particles and toxic volatile medium, double-ended machine seal should be injected into the sealed chamber isolation fluid, the pressure is generally higher than the medium pressure 0.07 ~ 0.1MPa. 2. Sealing material Chemical 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 is the best on the cemented carbide, the price is high On the one hand, the hardness difference between the two is not reasonable, so it is best to distinguish between media characteristics.
