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.
