How to deal with the inability of the cutting sewage pump to absorb water:
Firstly, check if the water pump you have selected is equipped with self priming function. If not, replace it with one with self priming function. Or install a bottom valve, and the first time the tank water enters, it can also form a certain self suction capacity. Generally, 2 meters is not a problem. The end cause is the presence of air in the pump body or the accumulation of air in the inlet pipe, or the unsatisfactory filling and suction of the bottom valve is not tightly closed, the packing of the air extractor is severely leaking, and the gate valve or flap valve is not tightly closed. Solution: First increase the water pressure, then fill the pump body with water, and then turn it on. At the same time, check whether the check valve is tight and whether there is any air leakage in the pipeline and joints. If any air leakage is found, apply lubricating oil or mixed paint to the joint after disassembly, and tighten the screws. Check the oil seal ring of the pump shaft, and if it is severely worn, replace it with a new one. Pipeline leaks water or air. It is possible that the nut was not tightened tightly during installation. If the leakage is not severe, it can be applied to the area where the air or water is leaking, or to the area where the asphalt is stirred. Temporary repairs can be done with damp mud or soft clay. If there is water leakage at the joint, a plate can be used to tighten the nut. If the leakage is severe, it must be disassembled and replaced with a cracked pipe; Reduce the head and press the nozzle of the water pump 0.5m underwater.
