Problems solved by technology

[0003] At present, when the multistage centrifugal pump is working, each impeller generates an axial force pointing to the direction of the impeller inlet. The number of impellers installed on the central shaft of the multistage centrifugal pump is large, so the axial force is very large, so it will pass through the balance drum, The balance disc type and the impeller symmetrical installation type (self-balancing type) balance the axial force of the multi-stage centrifugal pump. The self-balancing multi-stage centrifugal pump will generate heat. In order to ensure that the centrifugal pump is in a suitable working environment, a cooling fan will be installed. Heat dissipation, but the current cooling fan will also start when the temperature is not high, and cannot adjust the power according to the temperature, wasting resources

Abstract

The invention discloses an energy-saving self-balancing multi-stage centrifugal pump, comprising a protective casing, a centrifugal pump body is arranged inside the protective casing, a temperature sensor is arranged on the inner wall of the top of the protective casing, and an outer wall on one side of the protective casing is provided with a plurality of There are several heat dissipation ports, and a heat dissipation fan is arranged on one side of the plurality of heat dissipation ports. A sealing plate is hinged on the inner wall of each heat dissipation port, and an inclined surface is formed on one side of the bottom of each heat dissipation port. The bottom of the sealing plate and the inclined surface are connected A dust removal mechanism is arranged between, and a connecting plate is fixedly connected to the outer wall of the top of each sealing plate. The invention can detect the temperature in the protective casing by setting the temperature sensor, and adjust the power of the cooling fan according to the temperature data, so as to save energy. The sealing plate seals the heat dissipation port, so that other garbage such as external dust and impurities will not enter the protective casing.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to an energy-saving self-balancing multistage centrifugal pump. Background technique [0002] Centrifugal pumps work by rotating the impeller to cause centrifugal motion of water. Before the pump is started, the pump casing and the suction pipe must be filled with water, and then the motor is started, so that the pump shaft drives the impeller and the water to rotate at a high speed. The basic structure of the centrifugal pump is composed of six parts: the impeller, the pump body, the pump shaft, the bearing, the sealing ring, and the stuffing box. [0003] At present, each impeller of the multi-stage centrifugal pump generates an axial force directed towards the inlet of the impeller. The number of impellers installed on the central shaft of the multi-stage centrifugal pump is large, so the axial force is very large. The balance disc type and the impeller symmetrical in...
