High-efficiency energy-saving large-flow self-priming pump with wear-resistant middle-opening impeller

Abstract

The efficient energy-saving large-flow self-priming pump comprises a plate body, a base is fixedly installed on the plate body, a pump body is fixedly installed on the base, a driving motor is fixedly installed on the pump body, and an output shaft of the driving motor penetrates through a driving hole in the pump body. A driving motor is arranged in the pump body, an impeller is fixedly installed on an output shaft of the driving motor, a water outlet pipe is fixedly connected to the pump body, a water inlet is formed in the pump body, and the water inlet is connected with a filtering assembly through a water inlet pipe. The negative pressure is formed in the pump body, water flow can be sucked through the water inlet pipe on the water inlet, the sucked water flow can be discharged through the water outlet pipe through extrusion of the impeller, impurities in the water flow can be filtered through the filtering assembly, impact and load of the impurities on the impeller are reduced, and the efficient and energy-saving effects are achieved.

Description

technical field [0001] The invention relates to the technical field of self-priming pumps, in particular to a high-efficiency, energy-saving, large-flow self-priming pump with a wear-resistant split impeller. Background technique [0002] In the chemical industry, smelting, chemical fiber, titanium dioxide, rare earth, pesticide, papermaking, light industry, food, sewage treatment, environmental protection, fire protection and other industries, the amount of self-priming pumps, especially corrosion-resistant self-priming pumps, is relatively large. The structure, performance and maintenance convenience are superior to the submerged pump, and there is a tendency to gradually replace the submerged pump, especially in the case where the suction height is greater than 1.5m, the self-priming pump shows its superiority, and the commonly used traditional gas-liquid mixing The self-priming principle of the type self-priming pump is: usually try to save a certain amount of water in t...

AI Technical Summary

Problems solved by technology

[0003] The existing high-flow self-priming pumps are constantly impacting the impeller and blades due to the impurities in the water during the water absorption process, which is easy to cause damage to the impellers and blades, which will lead to damage to the large-flow self-priming pump, and with the impurity in the self-priming pump Internal accumulation is easy to increase the use load of the self-priming pump impeller, resulting in waste of energy
