What should I do if the water pump pressure of the sprinkler is small?

First, the sprinkler pipe filter is clogged, because the water pumped by the sprinkler pump can not all be clean tap water, it may be dirty water or water pumped in the pond, so there are too many impurities in the water, the filter is easy to be mixed The object is blocked, such as sand, plastic bags, branches and other debris, only need to remove the filter inside the filter tee to clean, to ensure smooth, you can resume normal work, the location of the filter in the sprinkler Pump inlet pipe end.

Second, the impeller wears and deforms, causing the impeller of the sprinkler pump to rotate normally but cannot enter and exit the water normally, just replace the new impeller.

Third, there is a gap in the pump seal, which causes air to enter, and the pressure of the sprinkler is insufficient. The solution is to carefully check whether the pump in the work has leaking water.

Fourth, the sprinkler water pump does not work in the water pump, resulting in the phenomenon that the mechanical seal inside the pump is dry and dry, and the mechanical seal can be replaced.

5. The power of the transmission shaft is insufficient, so that the impeller in the pump does not reach the normal working speed, and the throttle can be increased.

How to maintain the sprinkler pump accessories

The water pump of the sprinkler is very important for a sprinkler, so our usual maintenance and maintenance is very important. If the sprinkler does not absorb water, follow these steps to quickly diagnose:

The first step is to check the switch. First check if the water pump suction port and the water outlet switch are open. The water pump is a self-priming pump. The first time you use it, you should pump water.

The second step is to check the filter. When the sprinkler pump is not smooth, check if there is any debris in the front section of the suction pipe to block the water inlet, and then check whether the inlet pipe is sealed one by one to check if there is a gas leakage failure.

The third step is to check the degree of vacuum. The water pumping height of the commonly used water pump should be less than 5 meters. Then check whether the water pump oil seal is damaged. The pump shaft leakage affects the vacuum degree. The seal should be replaced. When the engine speed is too low and the required vacuum is not achieved, The throttle is adjusted so that the speed is around 1700 rpm, and the engine speed varies depending on the gearbox.

The fourth step is to check the power take-off. Check if the power take-off is working, and the force take-off and the drive shaft will be disconnected, which will cause the pump to not work.

The fifth step is to hear the abnormal sound. Check to see if the pump speed is normal. Pay attention to whether there is any abnormal noise and judge whether the pump can not rotate normally because there are debris around the blade. However, it is important to note that the pump cannot be idling for a long time during the test, otherwise the service life will be shortened due to the high temperature of the pump.

If the pump does not discharge water, if the fault cannot be eliminated after detailed inspection according to the above steps, check whether the outlet filter or pump body is blocked due to the dirty tank being dirty for a long time. It is also very important to develop good car habits. The water irrigation should be cleaned regularly. In the winter, the sprinklers should drain the water tank and the water in the pump body to prevent the tank and the pump from freezing.
