The difference between vertical centrifugal pumps and vertical pumps: vertical centrifugal pumps are a kind of centrifugal pumps. From the perspective of centrifugal pumps, they are improved from the performance of vertical centrifugal pumps, making their performance much higher than The vertical centrifugal pump is more stable during operation. Compared with similar domestic products, the vertical centrifugal pump has the advantages of simple structure, good self-priming performance (self-priming height up to 5m), strong sewage discharge capacity, relatively energy-saving, and convenient maintenance. It is the first domestic product in the sewage pump series. . All indicators are leading domestically and have reached the international advanced level. It has broad application market development prospects. UHMWPE has the following excellent properties:
1. Strong wear resistance: The wear resistance of UHMWPE ranks first among plastics, 4 times higher than nylon 66 and PTFE, and 7-10 times higher than carbon steel and stainless steel.
2. Strong impact resistance: The impact strength of UHMWPE ranks first among general engineering plastics, 5 times that of (acrylonitrile/butadiene/styrene) copolymer, and can be maintained at minus 196°C Stability, which is a feature that any other plastic does not have.
3. The casing of the vertical centrifugal pump (that is, the pump body and the pump cover) constitutes the working chamber of the pump. The impeller, shaft and rolling bearing are the rotor of the pump. The suspension bearing component supports the rotor part of the pump, and the rolling bearing receives the radial force and axial force of the pump.
4. In order to balance the axial force of vertical centrifugal pumps, most pumps are equipped with sealing rings before and after the impeller, and there are balance holes on the back cover of the impeller. Because some pumps have little axial force, the back of the impeller There is no sealing ring and balance hole.
