Motor of booster pump and booster pump with the same

Abstract

The invention is suitable for the technical field of a motor, and discloses a motor of a booster pump and the booster pump with the same. The motor of the booster pump comprises a housing, a front end cap, a back end cap, a first connector, a first elastic sealing member and a second elastic sealing member. The front end cap and the back end cap are respectively arranged at two ends of the housing and are connected with the housing in a fastening manner through the first connector. A first accommodating tank is arranged on the front end cap in a concave manner. The first elastic sealing manner is accommodated in the first accommodating tank and is provided with a first sealing part which projects from the first accommodating tank. A second accommodating tank is arranged on the back end cap in a concave manner. The second elastic sealing member is accommodated in the second accommodating tank and is provided with a second sealing part which projects from the second accommodating tank. The housing is provided with a front matching surface which abuts against the first sealing part and a back matching surface that abuts against the second sealing part. The motor of the booster pump successively settles a problem of insufficient waterproof sealing in the motor of the booster pump. Long service life and high use safety of the motor are ensured. Furthermore the flatness requirement for the matching surfaces among the front end cap, the back end cap and the housing of the motor can be reduced.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a motor of a booster pump and a booster pump with the motor. Background technique [0002] A booster pump is a pump installed on a pipeline for boosting, and it is widely used in water pipes of water equipment such as water purifiers and water heaters. The booster pump is generally driven by a motor. Since the booster pump is generally used in water equipment, the motor of the booster pump should also meet certain waterproof and sealing requirements in the design. However, in the prior art, there are many deficiencies in waterproof and sealing in the structural design of the motor of the booster pump, which are specifically reflected as follows: [0003] 1) The fit between the front end cover of the motor and the front mating surface of the motor casing, and the mating place between the rear end cover of the motor and the rear mating surface of the motor casing are only achieved ...

AI Technical Summary

Problems solved by technology

[0003] 1) The fit between the front end cover of the motor and the front mating surface of the motor casing, and the mating place between the rear end cover of the motor and the rear mating surface of the motor casing are only achieved through the fitting of the two mating surfaces at the mating place. In this way, on the one hand, it will increase the flatness requirements of the mating surfaces of the front end cover, the rear end cover and the casing, thereby increasing the processing difficulty of the front end cover, the rear end cover and the casing; on the other hand, due to the In the mass production of covers, rear end covers and casings, it is difficult to ensure the flatness of the mating surfaces of the front end cover, rear end cover and casing, so that the matching of the front end cover and the front mating surface of the casing, the rear end cover There will be a certain fit gap at the mating surface with the back of the casing, and then the outside water can seep into the casing from this gap, seriously affecting the service life and safety of the motor

[0004] 2) The casing of the motor is generally bent into a cylindrical shape with plates, and the two ends of the motor are generally fastened and connected by buckles. The water can enter the casing from this gap, which seriously affects the service life and safety of the motor

[0005] 3) The casing and the base of the motor are generally fastened and connected by screws. In this way, screw holes for the screws to pass through should be provided on the casing. In this way, in specific applications, external water will penetrate into the casing from the screw holes , thus seriously affecting the service life and safety of the motor
