——-————product structure


1, HW pump is mainly composed of pump cover, impeller, pump body, pump shaft, shaft sleeve and bearing body (caliber < 350mm) or bearing frame (diameter > 400mm) and other main components.

2. The pump cover is connected with the pump body and the water inlet pipe respectively. There should be proper clearance between the pump cover plane and the impeller plane. Too small clearance will produce friction; If the gap is too large, the pressure water in the pump body will backflow and reduce the efficiency of the pump. The actual use of the appropriate gap 0.3~0.7mm(push the pump shaft to the inlet end of the pump). The gap can be adjusted by increasing or decreasing the thickness of the paper pad.

3, the shaft seal device is composed of packing, packing gland, packing ring and packing box on the pump body (100HW, 150HW and 200HW pump without packing ring). Its role is to prevent air inhalation pump and prevent water from the pump too much along the shaft.

4, shaft sleeve to protect the pump shaft. It can be replaced after wear.

5. Pump shaft is supported by single row centripetal ball bearings. The amount of lubricating oil available for bearings should be controlled between the lines of the oil benchmark; It can also be lubricated with grease, which can be added when assembling pumps. In use by removing the front cover and rear cover to supplement.

6. The screw hole on the upper end of the pump body is used for filling water or connecting the vacuum pump to pump air and water.

7, in order to expand the scope of use of the pump, to meet the different requirements of users, can cut the outer diameter of the impeller or change the impeller with different performance (plus letter "A").

8, 100~350HW pump accessories have the inlet and outlet stay bend, live bend, bottom valve and pulley or coupling; The accessories of 400 ~ 650HW pump are inlet and outlet stay bend, check valve and pulley or coupling. Available for users to choose.
