Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a high-rise partition special pump with self-circulating cooling. Background Art

[0002] When the water pump is in use, the impeller rotates at high speed, and the liquid in it rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and ejects outward. The speed of the ejected liquid gradually slows down in the diffusion chamber of the pump casing, and the pressure gradually increases. Then it flows out from the pump outlet and the discharge pipe. At this time, a vacuum low-pressure area with neither air nor liquid is formed at the center of the blade because the liquid is thrown to the surroundings. Under the action of the atmospheric pressure on the pool surface, the liquid in the liquid pool flows into the pump cavity through the suction pipe. In this way, the liquid is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe.

Combined with its specification and drawings, the diversion and pressurization mechanism in its scheme is composed of four groups of impeller mechanisms located in the water pump casing, each of which is mainly composed of a first impeller and a guide plate. The first impeller water inlet of the impeller mechanism of the upper stage extends into the guide plate water outlet hole of the impeller mechanism of the next stage. However, if the entire pump body is running for a long time and the water in the pump body cannot be effectively discharged, the continuous rotation of the impeller will inevitably cause the water temperature inside the pump body to rise. At this time, the entire pump body is in a high temperature state, and the heat cannot be effectively dissipated, which poses certain safety hazards to the entire pump body. Summary of the invention

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0023] like Figures 1 to 7As shown, a high-rise partition-specific pump with self-circulating cooling includes a water pump body 1, wherein the water pump body 1 includes a water pump casing 13, a water pump base 14 and a first guide casing 15, wherein the water pump base 14 is arranged at one end of the water pump casing 13, and a plurality of first guide casings 15 are arranged at the other end of the water pump casing 13, and a second guide casing 16 is sandwiched between the plurality of first guide casings 15, and a plurality of water outlet pipes 161 are arranged on the surface of the second guide casing 16, and each of the water outlet pipes 161 is provided with an external thread on the surface, and the water outlet pipe 161 can be connected to an external pipe or water valve by using the external thread, and a plurality of guide impellers 2 and a driving assembly 3 for driving the guide impellers 2 are arranged inside the water pump body 1, and a plurality of first inclined guide plates 21 allowing water to pass through are arranged inside the guide impeller 2, and a plurality of second inclined guide plates 151 allowing water to pass through are arranged inside the first guide casing 15, and the driving assembly 3 for driving the guide impellers 2 is arranged inside the guide impellers 2, and a plurality of first inclined guide plates 21 allowing water to pass through are arranged inside the first guide casing 15, and a plurality of second inclined guide plates 151 allowing water to pass through are arranged inside the driving assembly 3 for driving the guide impellers 2. Component 3 includes a drive motor 31 and a drive shaft 32. The drive motor 31 is arranged inside the water pump housing 13. The top of the drive motor 31 is connected to the drive shaft 32. Each drive shaft 32 is connected to the guide impeller 2. After being arranged in this way, the drive motor 31 can drive the drive shaft 32 to rotate. When the drive shaft 32 rotates, each guide impeller 2 will also rotate. When the guide impeller 2 rotates, water will flow in from the first inclined guide plate 21 and be thrown upward to the second inclined guide plate 151 inside the first guide housing 15 under the action of centrifugal force, and then continue to be thrown upward to the inside of the second guide housing 16 under the action of the flow channel formed by the second inclined guide plate 151. If the external water outlet pipe 161 of the second guide housing 16 is connected to the pipeline, then the water can flow out normally. If the outside of the second guide housing 16 is not connected to the pipeline, then the water inside the entire water pump body 1 will flow out from the top.

[0024] In this embodiment, the surface of the water pump body 1 is further provided with a pump body water inlet 11 and a pump body water outlet 12, and a circulation guide component 4 is provided between the pump body water outlet 12 and the pump body water inlet 11, and a heat dissipation component 5 is provided on one side of each circulation guide component 4. Specifically, the circulation guide component 4 includes a circulation support shell 41 and a guide pipe 42, and one end of the circulation support shell 41 is provided with a first support plate 412, and the first support plate 412 is connected to the flange 131 of the side wall of the water pump shell 13, and the surface of the circulation support shell 41 is provided with a plurality of heat dissipation passages. Hole 411, a guide pipe 42 is arranged inside the circulation support shell 41, and the guide pipe 42 is placed in a spiral state. One end of the guide pipe 42 is connected to the pump body water outlet 12, and the other end is connected to the pump body water inlet 11. The heat dissipation component 5 includes a fan support plate 51 and a heat dissipation fan 52. A second support plate 413 is arranged inside the circulation support shell 41, and a fan support plate 51 is arranged at the end of each second support plate 413. A plurality of heat dissipation fans 52 are arranged on the surface of the fan support plate 51, and the air outlet of the heat dissipation fan 52 is aligned with the guide pipe. On the surface of the pipe 42, a water flow solenoid valve 6 is provided between the pump body water outlet 12 and the two ends of the guide pipe 42. The water flow solenoid valve 6 is used to control the opening and closing of the water path. After such a setting, whenever a plurality of water outlet pipes 161 on the entire water pump body 1 are closed or only one water outlet pipe 161 is left to discharge water, if the rotation speed of the driving motor 31 remains unchanged, the continuous rotation of the guide impeller 2 will cause the water temperature inside the water pump body 1 to rise. At this time, the water flow solenoid valve 6 opens and allows water to pass through, and the water will flow from the pump body water outlet 12 to the inside of the guide pipe 42. Since the guide pipe 42 is arranged in a spiral state, the time for water to flow outside the entire water pump body 1 will be prolonged, and the external air exchanges heat with the guide pipe 42 to achieve initial cooling of the guide pipe 42. Then the heat dissipation fan 52 will start working. At this time, the heat dissipation fan 52 continuously blows the surface of the guide pipe 42 to make it cool down faster. The water circulates through the guide pipe 42 and flows back to the inside of the water pump housing 13 through the pump body water inlet 11. If the temperature of the entire water pump body 1 is still high, the entire cooling water circuit circulation will continue to work.

[0025] Working principle and usage of this utility model:

[0026] External water enters the water pump housing 13 or the first guide housing 15 through the water inlet of the water pump base 14, and then the driving motor 31 drives the driving shaft 32 to rotate. When the driving shaft 32 rotates, each guide impeller 2 will also rotate. When the guide impeller 2 rotates, water will flow in from the first inclined guide plate 21 and be thrown upward to the second inclined guide plate 151 inside the first guide housing 15 under the action of centrifugal force, and then continue to be thrown upward to the inside of the second guide housing 16 under the action of the flow channel formed by the second inclined guide plate 151. If the external water outlet pipe 161 of the second guide housing 16 is connected to the pipeline, the water can flow out normally. If the outside of the second guide housing 16 is not connected to the pipeline, the water inside the entire water pump body 1 will flow out from the top. Whenever multiple water outlet pipes 161 on the entire water pump body 1 are closed or only one outlet is left When the water pipe 161 is able to discharge water, if the rotation speed of the driving motor 31 remains unchanged, the continuous rotation of the guide impeller 2 will cause the water temperature inside the water pump body 1 to rise. At this time, the water flow solenoid valve 6 opens and allows water to pass through. The water will flow from the pump body outlet 12 to the inside of the guide pipe 42. Since the guide pipe 42 is arranged in a spiral state, the time for water to flow outside the entire water pump body 1 will be prolonged. The external air exchanges heat with the guide pipe 42 to achieve initial cooling of the guide pipe 42. Then the heat dissipation fan 52 will start working. At this time, the heat dissipation fan 52 continuously blows the surface of the guide pipe 42 to make it cool down faster. The water circulates through the guide pipe 42 through the pump body water inlet 11 and flows back to the inside of the water pump housing 13. If the temperature of the entire water pump body 1 is still high, the entire cooling water circuit circulation will continue to work.
