Water supply pressure stations are an effective measure to alleviate insufficient water supply pressure in the city. The core is to improve the pump station, and the core of the pump station is the pump. The choice of water pump not only affects whether the water supply pressure station can work normally, but the reasonable selection of the selected type is directly related to the operating cost of the pump station.

Domestic general water supply pressure stations usually use centrifugal pumps. The centrifugal pump has the advantages of simple structure, no pulse infusion, and simple flow adjustment. According to the actual situation of the project, the category of centrifugal pump is first selected for the following considerations.

(1) Determine which characteristic pump is determined according to the characteristics of the medium. Such as water pump, corrosion -resistant pump, or chemical process pump and impurities pump. When the medium is highly toxic, valuable or radioactive, etc., if it is not allowed to leak substances, it is necessary to consider choosing a leak -free pump (such as shielding pump, magnetic pump, etc.) or two -end -end mechanical seal with leakage collection alarm device. If the medium is liquefied hydrocarbon and other volatile liquids, the low -vapor erosion balance should be used, such as cylindrical pumps.

(2) Select the horizontal pump and vertical pump according to the on -site installation conditions.

(3) Select single suction pumps, dual suction pumps, or small traffic centrifugal pumps according to traffic.

(4) Use single -level pumps, multi -level pumps, or high -speed centrifugal pumps according to the high and low.

After the above items are determined, the appropriate pump series can be selected according to the characteristics of different series pumps in various pumps and the conditions of the production plant. After the type, series and materials are selected, the model of the pump is determined according to the samples provided by the pump manufacturer and related parameters
