1、 Water pump filter screen of sprinkler is blocked
Because the water pumped into the sprinkler pump can not be all clean tap water, it may be the water drawn from dirty pool or pond. If there are too many impurities in the water, the filter screen is easily blocked by debris, such as sand, plastic bags, branches and other debris. Just remove the filter screen in the tee of the filter screen and clean it to ensure smooth flow, and then the normal work of the filter screen can be resumed It is located at the middle end of the water pump inlet pipe of the sprinkler truck.
2、 The impeller is worn and deformed
Too much sand and gravel during the pumping process of the sprinkler causes wear and deformation of the impeller. Although the impeller rotates normally, it can not enter and exit water normally. At this time, it is necessary to replace the new impeller.
3、 Water pump seal cracks
The solution is to carefully check whether there is a gap in the water pump to drain dew.
4、 There is no water in the pump of sprinkler truck
As a result, the mechanical seal in the water pump is dry burned without water, so the mechanical seal can be replaced.
5、 Insufficient power of transmission shaft
The impeller in the water pump does not reach the normal working speed, so increase the throttle.
