Efficient and energy-saving water pump

Abstract

The invention discloses an efficient and energy-saving water pump. The water pump comprises a mounting base, wherein two symmetrically-distributed first mounting plates are fixed to each of the front end and the rear end of the mounting base, a first mounting groove is formed in one side of the upper surface of the mounting base, a pump body is arranged above the first mounting groove, a second mounting plate and a third mounting plate are fixed to the upper surface of the mounting base, the second mounting plate is located between the first mounting groove and the third mounting plate, a bearing box is arranged between the first mounting groove and the second mounting plate, a motor is fixed to the upper surface of the third mounting plate, the bearing box is located between the pump body and the motor, and a pump shaft is fixed at the output end of the motor. Water entering the pump body enters an impeller from a baffle and is thrown out of a flow guide groove through centrifugal force generated by high-speed rotation of the impeller, the water entering the pump body is guided, the working efficiency of the water pump is improved, and the energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of centrifugal water pumps, in particular to a high-efficiency and energy-saving water 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, emulsion, suspoemulsion and liquid metal. [0003] Liquids, gas mixtures and liquids containing suspended solids can also be transported. 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 rotati...

AI Technical Summary

Problems solved by technology

[0008] The existing water pumps have low working efficiency and high energy consumption during use, and the working efficiency of the water pump is often affected by the aging and wear of the bearings. It is inconvenient to install and disassemble, which makes it difficult to transfer the water pump and replace parts. At the same time, the water pump is working. Vigorous shaking, so that the stability of the pump is not high
