进口氟塑料离心泵哪家品牌好

进口氟塑料离心泵Product Description:

Connecting mechanism, including pump shaft, impeller, jacking screw, flat key and lock nut; The outer sleeve of the pump shaft is provided with a lock nut, the center of one end of the lock nut is provided with a threaded hole, and the threaded hole sleeve is threaded on the outer side of the threaded part; One side of the lock nut is also threaded with a jacking screw, and the threaded end of the jacking screw is jacking on the outer circumferential surface of the first step shaft; The utility model has the advantages of simple structure, convenient processing, convenient disassembly and assembly, and avoids the phenomenon that the impeller is separated from the pump shaft during reverse rotation

进口氟塑料离心泵:

The new connecting mechanism of a plastic centrifugal pump comprises a pump shaft, an impeller, a top screw, a flat key and a lock nut, which is characterized in that a first step shaft is formed outward at one end of the pump shaft, a second step shaft is formed outward at the center of the other end of the first step shaft, a third step shaft is formed outward at the center of the other end of the second step shaft, and a transition shaft is formed between the third step shaft and the second step shaft, A fourth step shaft is formed outward from the center of the other end of the third step shaft; The outer side of the fourth step shaft is provided with a circumferential groove, the outer circumferential surface of the groove is provided with a first key groove, and the lower side of the flat key is inserted into the first key groove; An impeller is sleeved outside one end of the pump shaft, and a sleeve is formed outside one end of the impeller; The inner wall of the sleeve is provided with a second keyway; The fourth step shaft is inserted into the sleeve, and the upper side of the flat key is inserted into the second keyway; The outer side of the pump shaft is sleeved with a lock nut; The lock nut is fixed at the other end of the impeller; One side of the lock nut is also threaded with a jacking screw.

Principle:

Centrifugal pump uses impeller rotation to make water produce centrifugal movement to work. Before starting the water pump, the pump shell and suction pipe must be filled with water, and then the motor must be started to make the pump shaft drive the impeller and water to rotate at a high speed. The water is centrifugal, thrown to the outer edge of the impeller, and flows into the water pressure pipeline of the pump through the channel of the volute pump shell. In the past, the connection between the impeller and the pump shaft of the plastic centrifugal pump was mostly through hanging bolts or directly using threads; The lifting bolt is located between the pump shaft and the impeller. After a long time, it is difficult to remove the pump shaft after corrosion; If the method of direct threaded connection is adopted, the threaded column on one end of the pump shaft is screwed into the threaded sleeve in the center of the impeller
