first change the structure of the centrifugal pump, replace the ordinary impeller with a double suction impeller, in order to reduce the flow rate through the impeller, so as to reduce the NPSH of the centrifugal pump; It should also be noted that booster booster booster pumps should be installed in front of large high lift pumps to increase the inlet pressure so that the maximum load does not exceed 5 times the force that the sample can bear. The installation height of centrifugal pump is also required. The higher the installation height is, the lower the pressure at the medium inlet of the pump body will be. If you want to increase the pressure at the inlet, you should relatively reduce the installation height of the pump. Reasonable planning of the installation height is also an effective solution to the problem of cavitation. There are also requirements for the resistance of the suction pipe. The more elbows, valves and other components are set in the pipe, the resistance is mainly determined by using selection technology. The volatile content of the material in the vacuum state will increase, and the pressure will become low. Reducing some components required for installation and increasing the diameter of the suction pipe as much as possible are factors to prevent cavitation. As for the geometric size of the pump, increasing the potential of medical devices and medical packaging cannot be underestimated. The flow area at the inlet of the large pump will reduce the speed at the inlet of the impeller. Even if the kinetic energy and static pressure energy can be transformed into each other, the total value is unchanged. This auto manufacturer also smells the innovative opportunities contained in the changes in market trends, and the method can effectively prevent cavitation of the centrifugal pump

therefore, there is no need to worry about the shortcomings of centrifugal pumps. As long as there are certain ways to solve them, the shortcomings will become minor, so that centrifugal pumps can be better used
