Efficient energy-saving self-priming pump

Abstract

The invention relates to the technical field of self-priming pumps, in particular to an efficient energy-saving self-priming pump. According to the efficient energy-saving self-priming pump, the design of a hollow driving motor device is adopted, under the action of centrifugal blades, external water enters a volute through a water inlet in the middle of a main shaft, and heat generated during working of a rotor and a stator is absorbed by water at the water inlet position in the middle of the main shaft, so that the heat dissipation effect inside the motor is achieved, and the problems that atraditional motor dissipates heat through the tail end fan to the motor shell, heat dissipation is not available in the motor, a certain resistance exists in high-speed rotation of the fan, and the electric loss is high are solved; the two ends of the main shaft and the motor shell are sealed through mechanical sealing, the stator and the rotor can be sealed in the motor shell, a water pump can be directly put into water for pumping work, and the working application range is wide. According to the self-priming pump, heat dissipation can be conducted through the motor shell, heat dissipation can be conducted through the internal water flow, internal and external double heat dissipation is achieved, and the heat dissipation effect is good.

Description

technical field [0001] The invention relates to the technical field of self-priming pumps, in particular to a high-efficiency and energy-saving self-priming pump. Background technique [0002] The self-priming pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline, and it is only necessary to ensure that there is a quantitative suction liquid stored in the pump body before work. Different liquids can use different material self-priming pumps. [0003] The traditional self-priming pump studio uses the motor shaft to drive the impeller inside the volute to rotate at high speed to achieve pumping work. Generally, self-priming pumps do not have self-priming function and cannot be used in water. [0004] The working chamber of the traditional self-priming pump drives the...

Problems solved by technology

[0003] The traditional self-priming pump studio uses the motor shaft to drive the impeller inside the volute to rotate at high speed to realize the pumping work. Generally, self-priming pumps do not have self-priming function and cannot be put into water.

[0004] The working chamber of the traditional self-priming pump drives the fan at the tail end to rotate at high speed through the motor shaft, generating counter-airflow to dissipate heat from the motor casing. There is no heat dissipation inside the motor, and there is a certain resistance to the high-speed rotation of the fan, resulting in high power loss.
