Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump with a front end cover connected. Background Art

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals.

[0003] They can also transport liquids, gas mixtures, and liquids containing suspended solids. Technical parameters for water pump performance include flow rate, suction head, head, shaft power, hydraulic power, and efficiency. Based on their operating principles, they can be categorized as positive displacement pumps and vane pumps. Positive displacement pumps transfer energy through changes in the volume of their working chambers; vane pumps transfer energy through the interaction between rotating blades and water. These pumps are classified into centrifugal, axial flow, and mixed flow types.

[0004] Traditional water pumps all use a separate matching structure of the end cover and the pump body, which leads to coaxiality deviation in the processing of several parts of a machine, resulting in a certain proportion of unqualified noise after assembly. Summary of the Invention

DETAILED DESCRIPTION

[0029] It should be understood that the specific embodiments described herein are intended merely to illustrate the present invention and are not intended to limit the present invention. In the subsequent description, suffixes such as "module," "component," or "unit" used to designate components are used solely to facilitate the description of the present invention and have no inherent meaning. Therefore, "module," "component," or "unit" may be used interchangeably.

[0030] like Figure 1-6 As shown, the water pump with the front cover connected includes: a pump body, a water inlet 16, a water outlet 17, an impeller 11, a motor, a fan and a sealed chamber 12; the pump body includes a front pump body and a rear pump body; the water inlet 16 and the water outlet 17 are arranged on both sides of the upper end of the front pump body and are located at the same horizontal height; the sealed chamber 12, the impeller 11 and the flow channel cavity 18 are arranged on the front pump body; the front cover is integrally formed with the front pump body; the motor is arranged in the rear pump body; the rear cover is arranged on the rear pump body; wherein, the front cover and the rear The covers are both provided with ventilation holes. When the motor drives the fan installed at the tail end of the rotor to generate wind, the wind enters through the ventilation holes on the rear end cover, passes through the motor nail holes 7 set in the rear end pump body to flow out from the ventilation holes on the front end cover, thereby reducing the heat generated by the motor; wherein, the front end cover and the rear end cover are both provided with ventilation holes; wherein, the impeller 11 set in the front end pump body is driven to rotate by the motor, so that the impeller 11 drives water to flow from the water inlet 16 into the flow channel cavity for step-by-step pressurization, and then flows out from the water outlet 17.

[0031] In an embodiment of the present invention, the water inlet 16 is arranged on the left side of the upper end of the front pump body; the water outlet 17 is arranged on the right side of the upper end of the front pump body, and the water inlet 16 and the water outlet 17 are located at the same height and at opposite ends.

[0033] Furthermore, the number of ventilation holes on the front cover and the rear cover is at least one, that is, the front cover ventilation hole 13 and the rear cover ventilation hole 5 are each provided with at least one ventilation hole.

[0034] In the embodiment of the present utility model, an air cover 3 is provided on the outer shell of the rear end pump body.

[0035] In the embodiment of the present invention, the impeller 11 adopts a multi-blade tooth structure.

[0036] like Figure 1 As shown, the front end pump body is the part of the pump body to the left of the front end cover, including a seal 10; an impeller 11; a sealing chamber 12; a front end cover ventilation hole 13, etc.; the rear end pump body is the part of the pump body to the right of the front end cover, including a casing 1; a rear end bearing 2; a wind cover 3; a fan blade 4; a rear end cover ventilation hole 5; a stator with winding 6; a motor nail hole 7; a rotor 8; a front end bearing 9, etc.

[0037] like Figure 3 and Figure 5 As shown, it also includes an inlet flow channel located at the water inlet 16 and an outlet flow channel located at the water outlet 17, as well as a water injection steam nail 20 arranged on the outlet flow channel. Water is driven to enter from the water inlet 16 through the impeller 11, and flows to the water outlet 17 through the inlet flow channel, the flow channel cavity 18 and the outlet flow channel.

[0038] In the embodiment of the present utility model, Figure 5 As shown in the figure, electrophoresis treatment is used to electroplate a layer on the surface of the casting, which can effectively prevent the rust of the casting from polluting the water quality and causing copper rust to damage the vortex pump impeller during operation; in addition, the pump body cavity is in contact with water during operation. The use of the entire copper flow channel insert can effectively reduce the pollution of the water quality caused by rust on the casting and ensure the smoothness of the flow channel, thereby stabilizing the product performance, reducing noise and preventing the impeller from getting stuck and causing the motor to stall and burn out.

The front cover has ventilation holes to improve the efficiency of the motor and the heat dissipation effect of the stator. When the motor is running, the rear cover also has ventilation holes. The wind is blown from the rear cover into the stator through the rotation of the fan blades, and then flows through the nail holes of the motor and is discharged from the front ventilation holes, thereby improving the heat dissipation effect of the motor.

[0040] The preferred embodiments of the present invention are described above with reference to the accompanying drawings, but are not intended to limit the scope of the present invention. Any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope and essence of the present invention shall fall within the scope of the present invention.
