The string of multi -level centrifugal pumps and the effects of adjustment on the pump, the strings of multi -level centrifugal pumps, and adjustment methods. When a single multi -level centrifugal pump cannot meet the conveying task, it can be parallel or connected or connected to the multi -level centrifugal pump. Operation in series.

The effects of the pump and the effects of the adjustment method on the pump are connected by the two same type pumps. Although the pressure head is not changed much, the total transport flow is increased. The total pressure head of the tandem is increased, the flow changes are not great, and the total efficiency of the series pump is the same as the single pump efficiency.

When the impeller rotates at a high speed on the axis of the motor, the liquid full of the impeller is under the action of centrifugal force, and it is shaken around the impeller from the faster between the impelios. At the same time, it is attracted to the second -level impeller through the flow channel of the guide shell. This is the principle. All the impeller and the shell will be flowing one by one to further increase the pressure of the liquid. After the impeller is superimposed step by step, you can get a certain raising.
