Pump maintenance considerations

In daily life, the use of pumps is more extensive. A water pump is a machine that is used to deliver or pressurize a liquid. It is the transmission of liquid mechanical energy to the liquid, which increases the energy of the liquid. It can transport liquids and can also transport gas-liquid mixtures or volumes containing suspended solids. When we use the pump, we will encounter maintenance problems. The following will introduce the pump maintenance precautions.

One is not to rely solely on "experience." For example, when a water pump leaks at the end of the valve, some operators will save time. Before each start-up, fill some dry soil with the inlet pipe, and then flush the soil to the bottom valve so that the bottom valve does not leak water. This method looks simple and easy, but it is not enough. Because when the water pump starts to work, the sand in the bottom valve will enter the pump with the water, wear the impeller, pump casing and shaft, etc., seriously affect the service life, the correct method should be to repair the bottom valve, it can not be repaired ,replace.

The second is to find out that the fault should be eliminated in a timely manner, and do not allow the unit to work “with sickness”. For example, when the shaft of the water pump is found to be heavily worn, it is necessary to increase the packing in time, otherwise it will cause leakage of the water pump shaft packing. Leakage of the water pump shaft packing not only makes the unit energy consumption is too large, but there will be cavitation, speed up the damage of the impeller, directly affect the service life of the water pump. For another example, if the pump is found to be in severe vibration, the machine should be shut down immediately for inspection. Otherwise, if the water pump is bent and deformed, a safety accident is likely to occur.

In the maintenance, not only strictly according to the pump maintenance precautions, we must also do maintenance work in daily use. Such as: after each use is over, the regular cleaning of the pump; check the ball bearings to keep clean; prevent debris from entering and so on.
