Abstract
A multi-stage water pump body comprises a pump body, wherein the pump body is matched with a pump cover to form a water pump casing and comprises a semi-circular casing; three semi-circular impeller grooves are formed side by side in the middle of the upper flat surface of the semi-circular casing in an axial direction to form three pump chambers; a semi-circular impeller shaft hole groove is formed in the axial center of the semi-circular casing; a water inlet pipeline and a water outlet pipeline, which are crossed and respectively communicate with the pump chambers, are integrally arranged on two sides of the lower part of the semi-circular casing respectively; external flanges are arranged at the end parts of the water inlet pipeline and the water outlet pipeline; and among the three impeller grooves, the middle impeller groove is a large impeller groove, of which the diameter is greater than those of the impeller grooves on two sides, and the impeller grooves on the two sides are small impeller grooves in the same size. The multi-stage water pump body has the characteristics of being simple and compact in structure, small in size, low in cost and convenient to use and mount, providing multiple stages of pump chambers so as to be made into a multi-stage water pump, improving the pump head and the pumping capacity, and the like.
