Chemical pump how to achieve high sealing state
 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, drain, prevent pollution, improve the environment, play Great effect. How does it achieve high seal? This question can be explained from the following two aspects.
Sealed 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 pumps rarely use packing seal, the mechanical seal-based, mechanical seal and With single and double face, balanced and unbalanced type, the balanced type is suitable for the sealing of high pressure medium (usually the pressure is greater than 1.0mpa). The double facet seal is mainly used for high temperature, easy crystallization, viscosity, containing particles As well as 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, two No hardness difference is not reasonable, it is best to distinguish between the characteristics of the media treated.

The production line is to make the inorganic powder into a soft core board by mixing, stirring and extruding, and the core board is shaped by different heating and pressing through a flexible support transmission system, and then the upper and lower metal sheets are in the continuous heat roller. Composite under pressure. The production line has transformed the com- bustible organic core material in the aluminum- plastic composite panel into a new production process of non-combustible inorganic core material through a unique process, and realized the A2 fireproof performance, inte- grated forming and fully automatic continuous production function.
