Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps and relates to a water pump, in particular to a high-sealing water pump. Background Art

[0002] The transportation of fluid substances is usually carried out with the help of water pumps, which are usually powered by motors. Depending on the use scenario, water pumps are sometimes used in fixed places, such as water supply rooms, and sometimes used in mobile places, such as drainage of certain basements or ponds and lakes. When the water pump completely enters the interior of the water flow, it is necessary to ensure that the water pump as a whole has sufficient waterproof performance, especially the motor part of the water pump. The better the sealing, the higher the waterproof performance and the lower the accident rate.

[0003] Since the motor is also immersed in water during operation, its waterproof sealing is extremely important. In existing water pumps, the waterproof housing and the motor are mostly connected by bolts and sealing rings that match the bolts. Since the heads of the bolts are exposed from the housing, the bolts are easily corroded by the liquid, and the fit with the sealing ring and the bolt hole becomes loose, which eventually leads to water leakage in the housing and damage to the motor. Summary of the Invention

[0004] The purpose of the utility model is to provide a high-sealing water pump with good sealing performance in order to solve the above problems existing in the prior art.

[0005] The objectives of the utility model can be achieved through the following technical solutions: a high-sealing water pump, comprising a water pump motor, characterized in that a water pump housing is provided at the upper end of the water pump motor, the motor shaft of the water pump motor extends out of the water pump motor and is connected to an impeller assembly, the water pump housing is provided with a water inlet and a water outlet, the water pump motor is provided with a fixing portion, the fixing portion is fixedly connected to the water pump motor by fixing bolts, the water pump motor is provided with four mounting grooves for installing the fixing bolts, and the four fixing bolts all extend into the mounting grooves, a filter housing is fixedly provided on the water pump housing, and the outer end portion of the filter housing is affixed to the water pump housing and the outer end surface of the water pump motor, the filter housing is provided with four sealing portions extending into the mounting grooves, the sealing portions seal the fixing bolts, and a sealing ring is fixedly provided between the water pump housing and the water pump motor.

[0006] In the above-mentioned high-sealing water pump, the impeller assembly consists of a fixing frame and blades. A positioning ring for sealing the motor shaft and positioning and rotating the impeller is fixedly arranged on the water pump motor. A groove for the positioning ring to extend into is provided on the fixing frame, and a ball is arranged between the positioning ring and the fixing frame.

[0007] In the above-mentioned high-sealing water pump, a clamping portion is provided at the lower end of the filter housing, and a clamping groove that fits with the clamping portion is provided on the water pump motor.

[0008] Compared with the existing technology, the high-sealing water pump seals the fixing bolts through the filter shell arranged on the water pump housing, thereby preventing the fixing bolts from being corroded by the liquid and affecting the sealing of the product.

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 、 Figure 2 、 Figure 3 As shown, the high-sealed water pump includes a water pump motor 1, and a water pump housing 2 is provided at the upper end of the water pump motor 1. The motor shaft of the water pump motor 1 extends out of the water pump motor 1 and is connected to an impeller assembly 3. The water pump housing 2 is provided with a water inlet and a water outlet for water intake, and the water pump motor 1 is provided with a fixing portion 4. The fixing portion 4 is fixedly connected to the water pump motor 1 by a fixing bolt 5. The water pump motor 1 is provided with four mounting grooves for installing the fixing bolts 5, and the four fixing bolts 5 are all extended into the mounting grooves. A filter housing 6 is fixedly provided on the water pump housing 2, and the outer end portion of the filter housing 6 is affixed to the outer end surface of the water pump housing 2 and the water pump motor 1. The filter housing 6 is provided with four sealing portions 7 extending into the mounting grooves. The sealing portion 7 and the filter housing 6 are integrally formed. The sealing portion 7 seals the fixing bolts 5 to prevent liquid from corroding the fixing bolts 5, thereby reducing the service life of the water pump and the water pump motor 1. A sealing ring 8 is fixedly provided between the water pump housing 2 and the water pump motor 1.

[0015] To be more specific, the impeller assembly 3 consists of a fixing frame 9 and blades 10. A positioning ring 11 is fixedly provided on the water pump motor 1 for sealing the motor shaft and positioning and rotating the impeller. A slot is provided on the fixing frame 9 for the positioning ring 11 to extend into, and a ball is provided between the positioning ring 11 and the fixing frame 9.

[0016] To be more specific, the motor shaft is driven to rotate by the motor, and the motor shaft extends into the fixed frame 9 of the impeller assembly 3 and drives the impeller assembly 3 to rotate. Since the positioning ring 11 extends into the fixed frame 9 and the fixed frame 9 rotates on the positioning ring 11, the sealing of the water pump motor 1 is enhanced.

[0017] In further detail, a clamping portion 12 is provided at the lower end of the filter housing 6, and a clamping groove is provided on the water pump motor 1 to fit with the clamping portion 12. The clamping portion 12 cooperates with the clamping groove of the water pump motor 1 to fix the filter housing 6 to the water pump motor 1.

[0018] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0019] Although this document frequently uses terms such as the water pump motor 1, water pump housing 2, impeller assembly 3, fixing portion 4, fixing bolt 5, filter housing 6, sealing portion 7, sealing ring 8, fixing bracket 9, blade 10, positioning ring 11, and clamping portion 12 in the figures, the use of other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
