Thus the centrifugal force is generated, under the action of centrifugal force, the liquid is dumped along the Blade Runner to the impeller outlet, and the liquid is collected and fed into the discharge tube through the worm shell. The liquid obtains energy from the impeller, increasing the pressure energy and speed energy, and relies on this energy to transport the liquid to the place of work. When an impeller does not allow the liquid to obtain sufficient energy, multiple impellers can be used in series or in parallel to work on the fluid. At the same time that the liquid is dumped to the impeller outlet, a low pressure is formed at the center of the impeller Inlet, and the pressure difference is generated between the liquid in the suction tank and the center of the impeller, and the liquid in the suction tank is continuously operated into the impeller under the action of this pressure difference. In this way, the impeller in the rotation process, one side of the constant liquid, while constantly giving the liquid with a certain amount of energy, the liquid discharge, so that the centrifugal pump work continuously. The medium-open pump is mainly composed of pump body, pump cover, sealing ring and rotor parts. Rotor parts are mainly composed of shafts and impeller mounted on the shaft, impeller retaining sleeve.

S Series Open Pump is a large number of general-purpose machinery and equipment, it is widely used in petroleum, chemical, power metallurgy, mining, ship selection, light industry, agriculture, civil and national defense departments, in the national economy occupies an important position. For this reason, the cavitation problem of the open pump in the S series refers to the pressure of the open pump at the entrance of the P1 equal to or less than the saturated vapor pressure PV of the liquid at the same temperature, the liquid vaporization, the bubble under high pressure, rapid condensation or rupture to produce a very high pressure, highly frequent impact, the pump body strong vibration and noise, And significant reduction in efficiency. Then, in the S series, the pump must reduce the cavitation allowance of the pump itself in order to prevent cavitation. There are several specific methods. Reduce the suction height or increase the height of the inversion, reduce the loss, for this reason, we can try to increase the pipe diameter, minimize the length of the pipeline, elbow and accessories, etc., the cavitation will increase during the operation of the medium open pump, so it is necessary to prevent the water from running under large flow for a long time.
