If the sprinkler pump does not absorb water, follow these steps to diagnose quickly:
The first step is to check the switch. First check whether the water pump outlet and outlet switch of the sprinkler pump is turned on. The water pump for the sprinkler is a self-priming pump. When the water is used for the first time, the water should be poured.
The second step is to check the filter. When the sprinkling of the water pump is not smooth, check the front section of the suction pipe for debris blocking the water inlet, and then check the inlet pipe line by stage to see if there is a leakage failure.
The third step is to check the degree of vacuum. The height of the water pump used for ordinary sprinklers should be less than 5 meters. Then check whether the water pump oil seal of the sprinkler is damaged or not. The leakage of the pump shaft will affect the vacuum level and the seal should be replaced. When the sprinkler engine speed is too low to reach the required vacuum, adjust the throttle to make the speed at about 1700 rev / min, the engine speed varies depending on the gearbox.
The fourth step is to check the power take off. Check if the sprinkler power take-off is working, and the power take-off and the drive shaft can cause the water pump to stop working.
The fifth step to listen to abnormal noise. Check to see if the speed of the sprinkler's water pump is normal and pay attention to whether there is any abnormal sound or not and determine if the pump cannot rotate properly due to debris. However, it is important to note that the pump cannot be idling for a long time during the test. Otherwise, the service life of the pump will be shortened due to the high temperature of the pump.
If the water pump of the sprinkler does not discharge water, after the detailed inspection according to the above steps, if the fault can not be eliminated, then check whether the outlet filter or the pump body is blocked due to a long time when the uncleaned water tank is too dirty.
It's also important to develop good habits. The water irrigation should be cleaned regularly. In winter, after using the watering vehicle, the water tank and the water in the pump body must be drained to prevent freezing and cracking of the tank body and the water pump.
