What is the situation that the water pump of the spray does not discharge water

There are many forms of spray water pump, some of which can be used directly on the back of the body and used as crop growth spray. This is mainly done by manpower, and the water inside is pressed out through a certain pressure. In this case, if water does not flow out, it will be blocked on the one hand and damaged on the other. What are the specific factors?

In addition to the artificial spray water pump, there are also electric ones, which use electric energy to replace manual work and complete the spray work more quickly. If this type of water pump fails to discharge water, there will be more factors. The main problem is the blockage and the problem of the pump. The blockage can be dredged.

The water pump of the spray cannot discharge water after being powered on, which may be caused by power interruption, too low power supply voltage, the pump cannot start normally, the pump impeller is stuck, the pump stator coil is short circuited, the cable is too long or too thin, and so on. These factors will cause the pump to fail to operate normally. Solve the problem from these factors. Check the fuse, control protection switch and protection device to see if it is due to power phase failure or power failure. Understand the problem, To solve the problem.
