Description

Technical Field

[0001] The utility model relates to the technical field of pipeline pumps, in particular to a water-cooled pipeline pump with a water-cooling circulation system. Background Art

[0002] In-line pumps are primarily used to transport clean water and other liquids with similar physical properties. They are suitable for conveying and boosting pressure in various industrial and water supply and drainage pipelines. Ordinary, general-purpose in-line pumps use standard motors, which rely primarily on a plastic fan mounted behind the motor for heat dissipation. This results in less than ideal heat dissipation. Components within the motor away from the fan continue to heat up, preventing effective heat dissipation and shortening the service life of these components. Furthermore, the fan prevents submersible operation. Furthermore, the pump, completely exposed to the outside world, is significantly affected by ambient temperature, resulting in less than ideal heat dissipation. Utility Model Content

[0003] The purpose of the utility model is to provide a water-cooled pipeline pump with a water-cooling circulation system to solve the problem that the motor heat dissipation of the pipeline pump is insufficient and the ambient temperature affects the heat dissipation effect of the motor.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A water-cooled pipeline pump with a water-cooling circulation system includes a base, a water-cooling cylinder is installed on the base, a motor is fixedly installed inside the water-cooling cylinder, a vacuum cavity exists between the outer wall of the motor and the inner wall of the water-cooling cylinder, a pump head is provided at one end of the water-cooling cylinder, the output end of the motor passes through the side wall of the water-cooling cylinder and is connected to the pump head, a water inlet is provided on the side of the pump head, a water outlet is provided on the top surface, a water inlet pipe and a water outlet pipe are provided on the outer wall of the water-cooling cylinder, one end of the water inlet pipe is communicated with the inner wall of the water outlet, and the other end is communicated with the vacuum cavity inside the water-cooling cylinder, one end of the water outlet pipe is communicated with the vacuum cavity inside the water-cooling cylinder, and the other end is communicated with the inner wall of the water inlet.

[0006] A further technical solution is that connecting flanges are fixedly installed on the water inlet and the water outlet.

[0007] A further technical solution is that brackets are fixedly connected to the bottom of the water-cooling cylinder and the bottom of the pump head, and the brackets are detachably connected to the base via fixing bolts.

[0008] A further technical solution is to provide an elastic washer on the fixing bolt.

[0009] A further technical solution is to provide a regulating valve on the water inlet pipe.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model arranges a water inlet pipe and a water outlet pipe on the outside of the water-cooling cylinder. When the water pumped out by the pump head passes through the water outlet, a small amount of water will enter the vacuum chamber through the water inlet pipe and then be discharged from the water outlet pipe, so that the water in the vacuum chamber keeps flowing at all times, thereby being able to cool the motor and dissipate heat. The service life of the components inside the motor will not be shortened due to the inability to effectively dissipate heat. At the same time, because the motor is cooled and dissipated by water cooling, the motor is completely isolated from the outside world, and the surrounding ambient temperature will no longer have any effect on the motor. Moreover, the pipeline pump can be used for both water and land. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Example 1

[0021] A water-cooled pipeline pump with a water-cooling circulation system includes a base 1, a water-cooling cylinder 2 is installed on the base 1, a motor 3 is fixedly installed inside the water-cooling cylinder 2, a vacuum cavity 4 is between the outer wall of the motor 3 and the inner wall of the water-cooling cylinder 2, a pump head 5 is provided at one end of the water-cooling cylinder 2, the output end of the motor 3 passes through the side wall of the water-cooling cylinder 2 and is connected to the pump head 5, a water inlet 6 is provided on the side of the pump head 5, and a water outlet 7 is provided on the top surface, a water inlet pipe 8 and a water outlet pipe 9 are provided on the outer wall of the water-cooling cylinder 2, one end of the water inlet pipe 8 is connected to the inner wall of the water outlet 7, and the other end is connected to the vacuum cavity 4 inside the water-cooling cylinder 2, one end of the water outlet pipe 9 is connected to the vacuum cavity 4 inside the water-cooling cylinder 2, and the other end is connected to the inner wall of the water inlet 6. When water enters the pump head 5 through the water inlet 6 and is pumped out from the water outlet 7, a small amount of water will enter the water inlet pipe 8 from the water outlet 7. This water will enter the vacuum cavity 4 as cooling water to cool the motor 3, and then re-enter the water inlet 6 through the water outlet pipe 9. In this way, the pipeline pump can use a small amount of water to circulate and cool the internal motor 3 during the water pumping process, thereby preventing the internal components of the motor 3 from being unable to effectively dissipate heat and shortening its service life.

[0022] Example 2

[0023] On the basis of embodiment 1, a connecting flange 10 is fixedly mounted on the water inlet 6 and the water outlet 7. The connecting flange 10 facilitates the connection of the pump head 5 with other pipelines.

[0024] Example 3

[0025] Based on Example 2, a bracket 11 is fixedly connected to the bottom of the water-cooling cylinder 2 and the bottom of the pump head 5. The bracket 11 is detachably connected to the base 1 via fixing bolts 12. The fixing bolts 12 ensure that the water-cooling cylinder 2 and the pump head 5 are stably mounted on the base 1, and the water-cooling cylinder 2 and the pump head 5 can be removed when maintenance work is required.

[0026] Example 4

[0027] On the basis of embodiment 3, an elastic washer is provided on the fixing bolt 12. The elastic washer prevents the fixing bolt 12 from loosening.

[0028] Example 5

[0029] Based on Example 4, a regulating valve 13 is provided on the water inlet pipe 8. Because the heat generated by the motor 3 varies when operating at different powers, the amount of cooling water supplied can be controlled by the regulating valve 13 according to actual conditions to ensure a sufficient cooling effect. At the same time, no excess water enters the vacuum chamber 4 for cooling, but is directly discharged from the water outlet 7, thereby improving the working efficiency of the pipeline pump.

[0030] Example 6

[0031] like Figure 6 As shown, the pump head is set at the bottom of the cooling cylinder, and the base is set at the bottom of the pump head, so that the pipeline pump is set as a vertical structure. It can also play the role of the pipeline pump with a horizontal structure distribution as in Examples 1-5, but can be applied to other different installation conditions.

[0032] Working principle: When in use, first connect the corresponding pipes on the water inlet 6 and the water outlet 7 through the connecting flange 10, then put the pipeline pump into the depth of the water to be pumped out, start the motor 3 to make the pump head 5 work, and the water entering the pump head 5 through the water inlet 6 will be pumped out from the water outlet 7, and then discharged to the designated location. In the process of water being pumped out through the water outlet 7, a small amount of water will enter the water inlet pipe 8 from the water outlet 7. The water will enter the vacuum cavity 4 as cooling water to cool the motor 3, and then re-enter the water inlet 6 through the water outlet pipe 9. In this way, the pipeline pump can use a small amount of water to circulate during the pumping process to effectively cool the internal motor 3, thereby preventing the internal components of the motor 3 from being unable to effectively dissipate heat and shortening its service life.

[0033] Although the present invention has been described herein with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and implementations may be devised by those skilled in the art that fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope of the drawings and claims disclosed herein, various variations and modifications may be made to the components and / or layout of the subject combination arrangement. In addition to variations and modifications to the components and / or layout, other uses will also be apparent to those skilled in the art.
