How to choose a pump？

Water pump is a large number of general-purpose machinery and equipment, it is widely used in petroleum, chemical, electric power, metallurgy, mining, ship selection, light industry, agriculture, civil and national defense departments, occupies an important position in the national economy. Therefore, vigorously reduce the pump energy consumption, energy conservation with a very great significance.

The so-called rational selection of pumps, that is, to take into account the pump unit and pumping station investment and operating costs and other comprehensive technical and economic indicators, so that it meets the economic, safety, applicable principles. Specifically, there are the following aspects.

1. Must meet the requirements of the use of flow and head, that is, the requirements of the pump operating point [device characteristic curve and the intersection of the pump performance curve is often maintained in the high-efficiency zone operation, so that both the provincial power and is not easy to damage the machine parts.

2. Selected pumps should be small, light weight, cheap, but also have good characteristics and high efficiency.

3. Good resistance to vapor corrosion performance, which can reduce the depth of excavation of the pump room, but does not make the pump vapor corrosion, smooth operation and long life.

4. According to the selected pump pump station, engineering investment, low operating costs.
