A horizontal multistage pump

Abstract

The invention relates to the technical field of water supply equipment, and discloses a horizontal-type multistage pump. The horizontal-type multistage pump comprises a base plate. The upper surface of the base plate is fixedly connected with the bottom of a pump body through a support. The right side face of the pump body is fixedly connected with a protection cover. A first driving motor is fixedly installed on the inner wall of the protection cover, and an output shaft of the first driving motor extends to an inner cavity of the pump body. The left side face of the output shaft of the firstdriving motor is fixedly connected with a rotating shaft. Due to the fact that the horizontal-type multistage pump is provided with electric heating panels, scraper blades and electric push rods, theelectric heating panels can heat the inner cavity of the pump body, accumulated ice located on heat transfer plates begins to melt, the electric push rods are used for driving the scraper blades to make contact with the accumulated ice, the accumulated ice is disengaged from the heat transfer plates and then flows out of the pump body through a water outlet hole, the condition that the accumulated ice is generated on the inner wall of the pump body is avoided, the problem that the amount of the accumulated ice inside the multistage pump is large and thus normal operation of the multistage pump can be influenced is solved, the multistage pump can operate normally, and hence normal operation of the water supply equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to a horizontal multistage pump. Background technique [0002] Compared with single-stage pumps, multi-stage centrifugal pumps are different in that multi-stage pumps have more than two impellers, which can absorb and press water in multiple stages, so as to raise the water to a very high position. Increase or decrease the number of stages of the pump impeller as needed. Multistage pumps are mainly used for mine drainage and water supply for cities and factories, and are rarely used for agricultural irrigation. They are only suitable for lifting water in high-lift and small-flow high mountain areas to solve the difficulty of drinking water for humans and animals. There are two types of multi-stage high-center pumps: vertical and horizontal. The pump shaft of the multi-stage centrifugal pump is equipped with two impellers connected in series. Compared with the general...
