Product Introduction of Fully Automatic High Flow Diesel Engine Pump Station:
The CHW type fully automatic high flow diesel engine pump station is a horizontal, single-stage, single suction, volute mixed flow pump.
Suitable for transporting clean water or other liquids with physical or chemical properties similar to water.
The temperature of the liquid being transported should not exceed 50 ℃.
Widely used in various occasions such as farmland irrigation, industrial and urban water supply and drainage.
The meaning of the model of the fully automatic high flow diesel engine pump station:
Taking 300HW-8A as an example
300- Pump inlet and outlet diameter (mm)
CHW - Diesel Engine Vortex Shell Mixed Flow Pump
8- Design head (m)
A - Cut the outer diameter of the impeller or replace it with an impeller of different performance.
Fully automatic high flow diesel engine pump stationPerformance range:
Flow rate: 70~4500m3/h
Lift: 4~20m
Caliber: 150-650mm
Fully automatic high flow diesel engine pump stationStructural features:
1. The CHW type fully automatic high flow diesel engine pump station is mainly composed of main components such as pump cover, impeller, pump body, pump shaft, shaft sleeve, and bearing body (diameter ≤ 350mm) or bearing frame (diameter ≥ 400mm).
2. The pump cover is connected to the pump body and the inlet pipe respectively. There should be an appropriate gap between the pump cover plane and the impeller plane. A small gap can cause friction; Excessive clearance can cause a large amount of pressure water in the pump body to reflux, reducing the efficiency of the pump. The suitable gap for actual use is 0.3-0.7mm (pushing the pump shaft towards the inlet end of the pump), and the gap can be adjusted by increasing or decreasing the thickness of the paper pad.
3. The shaft seal device consists of packing, packing gland, packing ring, and seasoning box on the pump body (150CHW and 200CHW pumps do not have packing rings). Its function is to prevent air from being sucked into the pump and to prevent excessive water from flowing out along the shaft from the pump
