Two kinds of pumps are made of three parts. One is well on the part, which comprises a motor, a bearing box and a pump seat, used for supporting power, weight, nitric pump water diversion. Two is in the same transmission part, including the water delivery pipe, transmission shaft and bearing bracket, etc., from the transmission power and compliance. Three is the underground part, including the leaf Han, pump shell, Ye Hanzhou, etc., is the body of the pump, the water absorption, water extraction.
The working principle of the well pump is basically the same as that of the general horizontal centrifugal pump. The power is driven by the driving shaft to drive the pump impeller to rotate, the vacuum is formed at the inlet of the impeller, and the well water is sucked. In order to reduce the energy loss of the water conveyance, the high speed water flow from the blade is eliminated by the flow guiding shell, and then flows along the water pipe to the farmland through the water head.
Well pump has the following advantages:
1. The straw has the advantages of simple structure, the material and process requirements is not high, easy to manufacture.
2. high efficiency.
3. The engine installed in the wells, convenient installation.
4. Leaves immersed in water, do not need to water before starting.
5. The price is cheap.
