[导读]： 杨总前段时间尝试了租赁二手洒水车，但合作出现了一个小问题，让杨总有点心烦意乱，什么问题?那个洒水车的水泵不能吸水。 Mr Yang
Mr. Yang tried to rent a second-hand sprinkler some time ago, but there was a small problem in the cooperation, which made Mr. Yang a little upset. What's the problem? The water pump of the sprinkler can't absorb water.
The main problems of the sprinkler water pump not absorbing water:
1： The most likely problem is that the sprinkler filter is blocked, because the sprinkler can't put clean tap water into the water, which may be dirty pool or pond water, so there are too many water impurities, so the filter is easy to be broken, such as sand and plastic bags. Just take out the filter element in the filter screen and clean it, then it can return to normal operation. This screen is located near the sprinkler.
Second, it may be that the pressure of the sprinkler pump is not enough, which leads to the failure of the sprinkler pump to pump water, which is usually caused by two reasons:
1. Impeller passage or suction pipe is blocked, or impeller is worn or damaged.
2. Insufficient power, low speed. If the impeller is damaged, the pump needs to be replaced. The power is not enough. Just step on the gas.
