Sealing characteristics and making materials of heat transfer oil pump

Sealing characteristics and material The seal is made of hard alloy material with high mechanical strength and good wear resistance, which ensures the sealing performance under the condition of high temperature mechanical seal. The imported PTFE is used as the lip seal, which makes the sealing performance take a leap forward in the mechanical seal used in the kettle, which is 25 times more reliable than the rubber seal, and has extremely strong corrosion resistance. The bearing of the hot oil pump is immersed in the conveying medium, and is lubricated and cooled by the conveying medium. Generally, corrosion-resistant, high-strength engineering plastics, corundum ceramics, stainless steel, etc. are used as the production materials. The more commonly used bearings in China are mostly graphite and reinforced plastics. Graphite, especially impregnated graphite, has good self-lubrication, heat-resistant corrosion, low friction coefficient, and a wide range of applications. However, graphite is brittle and has low strength. It is sensitive to shaft bending and local overload, and special attention should be paid. The left end of the pump shaft of the heat transfer oil pump is provided with an impeller, the pump shaft is supported by a sliding bearing, and the right end is provided with an inner magnetic rotor. The bracket connects the pump and the motor and ensures the positional accuracy of the inner and outer magnetic rotors. Thermal oil pumps are generally made of corrosion-resistant, high-strength engineering plastics, corundum ceramics, stainless steel, etc., which have good corrosion resistance and can protect the conveyed medium from pollution. Structural characteristics of heat transfer oil pump The heat transfer oil pump consists of a coupling, a drive motor and a pump. For example, the plastic alloy composed of ultra-high molecular weight polyperfluoroethylene propylene and polytetrafluoroethylene, the former accounts for 0.1%-99.9% by weight, and the latter accounts for 99.9%-0.1% by weight, using dry powder co-grinding or dry powder wet Manufactured by the blending method of co-milling. It can be processed into various products by hot pressing or cold pressing and sintering, which overcomes the shortcomings of PTFE cold flow and easy deformation, and can prolong the service life.
