The sealing characteristics and production materials of heat transfer oil pumps

The sealing characteristics of the heat-conducting oil pump and the material made of the heat-conducting oil pump The sealing characteristics of the heat-conducting oil pump and its material The seal is made of cemented carbide materials with high mechanical strength and good wear resistance to ensure the sealing performance of the mechanical seals used in the high temperature kettle. Imported polytetrafluoroethylene is used as the lip seal, which makes the sealing performance a leap in the mechanical seal of the kettle. The reliability is 25 times higher than that of the rubber seal, and the corrosion resistance is extremely strong. 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 materials. The more commonly used bearings in China are mostly graphite and reinforced plastics. Graphite, especially impregnated graphite, has good self-lubricity, heat-resistant corrosion, low friction coefficient, and a wide range of applications. However, graphite is brittle and low in strength. It is very sensitive to shaft bending and local overload, so special attention should be paid. The left end of the heat transfer oil pump shaft is equipped with an impeller, the pump shaft is supported by a sliding bearing, and the right end is equipped with an inner magnetic rotor. The bracket connects the pump and the motor and ensures the position accuracy of the inner and outer magnetic rotors, and the wire drawing machine. Hot oil pumps generally use corrosion-resistant, high-strength engineering plastics, corundum ceramics, stainless steel, etc. as materials, which have good corrosion resistance and can prevent the transported medium from being polluted. The structural characteristics of the heat transfer oil pump The heat transfer oil pump is composed of a coupling, a drive motor and the pump. For example, a plastic alloy composed of ultra-high molecular weight polyperfluoroethylene propylene and polytetrafluoroethylene, the former accounts for 0.1% to 99.9% by weight, and the latter accounts for 99.9% to 0.1% by weight, using dry powder co-milling or dry powder wet Manufactured by the blending method of method co-milling. It is processed into various products by hot pressing or cold pressing sintering, which overcomes the shortcomings of cold flow and easy deformation of PTFE, and can extend the service life.
