Agricultural water pumps are widely used. How to properly use and maintain agricultural water pumps is essential for irrigation, drainage, and the normal operation and life of the pumps.
Installation of water pump
The installation and calibration of the water pump is the critical first step. Although the water pump unit has been calibrated before leaving the factory, it will cause varying degrees of deformation or looseness due to transportation and assembly. Therefore, the water pump must be installed while installing. Correction.
1. Installation steps
2. Precautions for water pump installation
Starting, running and stopping of the water pump
The starting, running and stopping of the water pump should be carried out in strict accordance with the operating regulations.
1. Start
2. Operation
3. Stop
Turn off the power after gradually closing the gate valve of the discharge line.
Third, the maintenance and maintenance of the water pump
In addition to using the pump strictly in accordance with the installation and operation instructions, two points should be noted: one is to avoid relying only on "experience". For example, when the bottom valve of the water pump leaks, some operators try to save trouble. Before each startup, fill some dry soil into the inlet nozzle, and then flush the soil to the bottom valve to prevent the bottom valve from leaking. This method looks simple and easy to implement, but it is not desirable. Because when the water pump starts to work, the sand and soil in the bottom valve will enter the pump with the water, which will wear the impeller, pump casing and shaft, which will seriously affect the service life. The correct method should be to overhaul the bottom valve. Replace in time. The second is to eliminate the fault in time and avoid letting the unit work "ill". For example, when the water pump shaft packing is found to be worn seriously, it is necessary to increase the packing in time, otherwise it will cause the water pump shaft packing to leak air. Leakage of the water pump shaft packing not only causes excessive energy consumption of the unit, but also causes cavitation, which accelerates the damage of the impeller and directly affects the service life of the water pump. For another example, if the water pump is found to vibrate severely, it should be shut down immediately for inspection. If the water pump shaft is bent and deformed, a safety accident is likely to occur.
After the pump unit and pipeline have been used for a period of time, the following maintenance work should be done:
