First, the clever method to lift the pump in the well
To lift a centrifugal water pump with a bottom valve from a well, the farmer often feels a lot of effort. This is because a large amount of water is trapped in the suction pipe, and the suction hose is also worn out. For this purpose, a rope can be put down in the well for a few minutes before the machine is stopped. The upper end should be fastened to the pump and the lower end should be more than 35 centimeters lower than the bottom valve. Then continue to try to lift the rope, when you feel the pulling rope has obvious resistance, indicating that the rope has caught the bottom valve. At this time, the pump can be stopped, and after a few minutes of waiting, it is estimated that the water in the suction pipe has leaked. It is easier to lift the suction pipe and the bottom valve.
Second, the pump main measures for energy saving
1. Try to shorten the length of the water transmission line, reduce the elbow, and expand the diameter of the outlet pipe.
2. Cancel the bottom valve, eliminate blockages in the pipeline, and increase the pore size of the filter.
3. To prevent the water pump from drawing in air, the water inlet must have a certain depth of submergence, and the water inlet should not be exposed to the surface due to vortices or a lowered water level.
4. The outlet should be as close as possible to the height of the drain to avoid lifting the outlet.
5. Efforts shall be made to reduce the running resistance of the power machine and the water pump. In addition to maintaining a good technical state of the power machine, attention shall be paid to adjusting the axial clearance of the water pump.
Greenhouse Vertical Hydroponics
Greenhouse Vertical Hydroponics allows you to grow fresh vegetables and fruits at much higher crop yields and relatively lower costs. Thus, not only is it a profitable undertaking, but one which has proven of great benefit to humanity. With Greenhouse Hydroponics, plants can be raised out of season resulting in better control and higher yields of crops.
