Application and characteristics of multistage pump
The multi-stage pump has the characteristics of high power, safe and stable operation, low noise and long service life. For transporting clear water or liquid with physical and chemical properties similar to water, it can also be used to transport oil, corrosive or abrasive media by changing the raw materials of pump overflow parts, sealing methods and adding cooling system.
It is mainly used for pressurized water supply of industry and high-rise buildings, fire-fighting pressurization, long-distance water supply, heating and other cold and warm water circulation pressurization and equipment matching, etc. it is suitable for small boiler water supply.
The multistage pump is multistage and segmented type. The suction inlet is located on the water inlet section in a horizontal direction, and the discharge outlet is vertical and upward on the water section. The lift can be increased or decreased according to the use needs. Whether the water pump device is excellent or not has a great influence on its function. The outlet of each impeller and the inlet and outlet center of the guide wing will reduce the flow of the water pump and the power difference of the head. It is necessary to pay attention to it when repairing the device.
The main parts of multistage pump are: water inlet section, middle section, water outlet section, guide vane baffle, shaft, sealing ring, tail cover and bearing body. The water inlet section, water outlet section and tail cover are made of cast iron, which together constitute the working room of the pump.
