Centrifugal pump characteristics and working principle
Centrifugal pump works: Centrifugal pump work, in addition to the pump, but also equipped with suction pipe, the end of the valve, pressure pipes and so on. Centrifugal pump in the pump start, the first filled with water plug to the pump casing water, the suction pipe and pump casing filled with water, and then start the pump. At this point power driven shaft pump, the impeller rotation, filled with impeller flow between the water channel. Under centrifugal force, the center of the impeller is thrown to the outer edge of the impeller, and the water enters the pump casing at a high speed. When water flows from the impeller, it gains energy (kinetic energy and pressure energy). Pipe centrifugal pump features: 1, the pump is vertical structure, import and export of the same caliber, and located in the same center line, the valve can be installed in the same pipeline, compact appearance, small footprint, low investment in buildings, If coupled with the protective cover can be placed outdoors. 2, the impeller is mounted directly on the motor shaft, the axial size is short, compact structure, the pump and motor bearing configuration is reasonable, can effectively balance the pump radial and axial load, thus ensuring the smooth operation of the pump, Small vibration, low noise. 3, shaft seal mechanical seal or mechanical seal combination, the use of imported titanium alloy seal, medium-temperature mechanical seal and the use of hard alloy material, wear-resistant seal, can effectively extend the service life of mechanical seals. 4, easy installation and maintenance, without moving the pipe system, as long as you remove the pump seat nut can extract all the rotor components. 5, according to the requirements of the use of flow and lift needs of the pump string, parallel operation. 6, according to the requirements of the pipeline layout using vertical and horizontal pump installation.
