Select the specific method of opening the pump

The middle -opening pump is a wide -purpose general machinery and equipment, which is widely used in oil, chemical, electricity metallurgy, mines, ship selection, light industry, agriculture and other fields. The reasonable selection of the pump is a comprehensive technical and economic indicator of the investment and operating costs of the water pump unit and the pump station.

Make it compliance with economic, safe, and applicable standards. Specifically, there are the following aspects: it is necessary to satisfy the requirements of traffic and raising, that is, the operating working -range point point of the pump (the intersection of the performance curve of the equipment characteristic curve and the pump) often maintains it in high -efficiency interval. It saves power and is not easy to damage machines.

The selected mid -pump should be small, light weight, low cost, good performance, and high power. It has good resistance to gas erosion, stable operation, and long service life. The selected pump project has less investment and low operating costs. The middle pump, also known as a single -stage double -absorbing cardiac pump, is the main feature of the transport medium.

The working principle of the operation of the middle pump: The impeller is installed in the pump shell, it is fixed on the pump axis, and the motor is directly driven by the motor. The liquid enters the pump through the bottom valve and inhaled tube. The drainage port on the pump shell is connected to the discharge tube. When the speed of the pump is kept unchanged, its pressure head is related to the diameter of the impeller.
