[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increases the energy of the liquid, and thus transports the liquid. Water pumps are mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. During the use of the pumping system, since the transported medium belongs to the heavy sewage series (including mud, waste branches, woven bags, rags, etc.), dirt often blocks the pump cavity and entangles the impeller, affecting the efficiency and normal use of the pump body. During maintenance, the entire pump body needs to be disassembled to complete the maintenance work. The maintenance cost is high and the efficiency is low, which is not conducive to the use of the pump body. For this reason, we propose a pump body structure with a quick maintenance function.
