Fire pump can not suck up the water to the root cause: one, because the bottom valve closed loosely. Two, because there is still air in the fire pump. Three, there is gas accumulation in the water inlet pipe. Four, the gate valve or tap door is not tightly closed. Five, the air pumping machine packing leakage. The above five points are why the fire pump can not suck the water, so how should we solve it?
We need to check whether the check valve of the fire pump is tightened, and whether there is air leakage at the pipeline and joint. If there is air leakage, we need to apply lubricating oil at the joint and tighten the screw after disassembly. Or we open the fire pump, to improve the water pressure, and then the pump body filled with water after the boot. Check the fire pump screw screw is not tight, there is no leakage or water, such as serious water leakage must be removed from the new, easy to crack the pipe; Reduce the head and push the nozzle of the pump into the water 0.5m.
Finally, we should check the oil seal ring of the pumping machine shaft. If there is serious consumption and wear, we should replace it in time.
