Problems solved by technology

Existing water pumps include a motor and a pump body. The motor drives the impeller in the pump body to rotate to pressurize the water. The motor will generate heat during operation. During the long-term working process of the motor, if the motor is not cooled in time, it will Seriously affect the normal operation of the motor, and even affect the service life of the motor. The current method is generally to add a set of water cooling device or air cooling device on the surface of the motor to cool down the motor. The existing problems are: the external device It makes the structure more complicated, and its additional devices need to consume energy when working, resulting in energy waste

Embodiment Construction

[0017] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0018] Such as figure 1 As shown, the new water pump includes a motor 1 and a pump body 2 with a pump chamber 3. The pump body 2 has a water inlet channel 5 and an outlet channel 6 communicated with the pump chamber 3. The pump chamber 3 is provided with an impeller 4. The above-mentioned motor The output shaft of 1 extends into the pump cavity 3 and the impeller 4 is fixedly connected to the output shaft of the motor 1. The water pump also includes a cylindrical pressure tank 7 with one end open, and a sealing cover 8 is sealed at the opening to seal The cover 8 is hermetically connected to the end of the motor housing which is close to the output shaft. The entire motor 1 is passed through the sealing cover 8 and the rea...

Abstract

The invention provides a novel water pump and belongs to the technical field of machinery. According to the invention, the problem of an unsatisfactory motor cooling effect in the existing water pump is solved. The novel water pump comprises a motor and a pump body with a pump cavity; the pump body is provided with a water inlet channel and a water outlet channel which are communicated with the pump cavity; an impeller is arranged in the pump cavity; the output shaft of the motor extends into the pump cavity, and the impeller is fixedly connected to the output shaft of the motor; the water pump also comprises a cylindrical pressure tank with an opening at one end; the opening is in sealed connection with a sealing cover; the sealing cover is in sealed connection with the end, close to the output shaft, of the motor shell; the entire motor penetrates through the sealing cover, and the rear end of the entire motor is located in a cavity formed by the inner side wall of the pressure tank, the sealing cover and the motor shell wall; a through hole is arranged on the sealing cover; the water outlet channel is communicated with the cavity via the through hole; and a water outlet hole communicated with the cavity is arranged on the side wall of the pressure tank. The novel water pump provided by the invention has the advantages of good cooling effect, convenience in carrying and beautiful appearance.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a novel 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, emulsions, suspoemulsions and liquid metals, etc., and can also transport liquid and gas mixtures. and liquids containing suspended solids. Existing water pumps include a motor and a pump body. The motor drives the impeller in the pump body to rotate to pressurize the water. The motor will generate heat during operation. During the long-term working process of the motor, if the motor is not cooled in time, it will Seriously affect the normal operation of the motor, and even affect the service life of the motor. The current method is generally to add a set of water ...
