Abstract

The invention relates to the field of water suction pumps, in particular to a multi-structure pump. According to the technical scheme, the multi-structure pump comprises a motor and a pump body; the pump body comprises a water inlet, a water outlet and a water inlet channel, the water inlet and the water outlet are formed in the same horizontal face, the position of the water inlet is higher than the height of the water inlet channel, and the motor is vertically arranged; the water inlet is connected with a first check valve used for preventing remaining water of the water inlet channel from flowing out from the water inlet after the pump is stopped, the water outlet is connected with a second check valve used for avoiding losing of the remaining water of the water outlet after the pump is stopped, and the other end of the second check valve is provided with a water outlet pipeline. According to the multi-structure pump, after the pump is stopped, the remaining water in the pump body can be stored for next-time pump opening, and the problem that when an existing water suction pump is opened, water needs to be irrigated into the water inlet pipeline or the water inlet pipeline needs to be vacuumized is solved.

Description

technical field [0001] The invention relates to the field of water pumps, in particular to a multi-structure pump. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, suspoemulsions and liquid metals, etc., and can also transport liquid and gas mixtures. and liquids containing suspended solids. The technical parameters of pump performance include flow rate, suction lift, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric pumps, vane pumps and other types. Positive displacement pumps use the change in the volume of their working chambers to transfer energy; vane pumps use the interaction between rotating blades and water to transfer energy, and ...
