Overview
1. Purpose:
The HW type pump 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 transported liquid should not exceed 50 ℃. Widely used in various occasions such as agricultural irrigation, industrial and urban water supply and drainage.
The performance range of HW pump: flow rate of 90-9000m '/h, head of 3.5-22m.
2. Characteristics:
Simple structure, reliable use, convenient decoration, high efficiency, small size, and light weight.
3. Transmission mode:
There are direct transmission and variable speed transmission. The commonly used power engines are electric motors and diesel engines. When ordering, the model of the power machine (power, speed) should be clearly specified in order to determine the specifications of the coupling or pulley.
4. Water pump direction:
When looking at the inlet of the water pump (650HW-5, -7, -10 pumps rotate clockwise), the impeller generally rotates counterclockwise

1. The HW type pump is mainly composed of main parts such as pump cover, impeller, pump body, pump shaft, shaft sleeve, and bearing body (diameter<350mm) or bearing frame (diameter>400mm) (Figure 1, Figure 2).
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 packing box on the pump body (100HW, 150HW, and 200HW 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.
4. The shaft sleeve is used to protect the pump shaft. After wear and tear, it can be replaced in a timely manner.
5. The pump shaft is supported by a single row radial ball bearing. Bearings can be lubricated with lubricating oil - the amount of oil should be controlled between the markings of the oil benchmark; Lubricating grease can also be used for lubrication - it can be added when assembling the water pump. Supplement by disassembling and assembling the front and rear covers during use
6. The screw hole on the upper end of the pump body is used for adding water or connecting a vacuum pump for pumping water.
To expand the range of use of the pump and meet different user requirements, the outer diameter of the impeller can be cut or a different performance impeller can be used (indicated by the letter "A").
The accessories of the 8.150-300HW pump include inlet and outlet bends, flexible bends, bottom valves, and pulleys or couplings; The accessories of the 400-650HW pump include inlet and outlet bends, check valves, and pulleys or couplings. Available for users to choose from. 9. The bearing models and packing specifications of the HW pump are shown in Tables 1 and 2.Structural diagram
