Description

Technical Field

[0001] The utility model relates to the technical field of axial flow cooling pumps, and more specifically to a high-efficiency axial flow cooling pump capable of adjusting water temperature. Background Art

[0002] The function of the cooling pump is to pressurize the coolant in the pipeline through the impeller to ensure that it circulates in the cooling system, allowing the coolant to circulate continuously through the terminal to take away heat to meet the terminal temperature requirements. In the cooling circulation system, the cooling pump is located between the refrigerator and the terminal, and the low-temperature liquid in the refrigerator is transferred to the terminal through the cooling pump. After heat exchange at the terminal, the heated liquid is returned to the refrigerator. The refrigerator uses the refrigeration circulation system to send the heated temperature to the cooling tower through the refrigeration pump for cooling, and returns the low-temperature liquid. The high and low temperatures are heat exchanged in the refrigerator through the refrigerant.

[0003] The existing dual-circulation system still needs to turn on all the equipment in the system when the temperature changes slightly. The system has low energy efficiency and it is difficult to achieve rapid response and constant temperature control in temperature control. Too many complex equipment also increases the failure frequency and management cost of the system. Utility Model Content

[0007] As a preferred embodiment, the bottom shell and the side wall shell are hollow structures.

[0008] As a preferred embodiment, the rotating shaft is also fixed with a first impeller and a second impeller, the first impeller is located between the first pipe plug opening and the first circulation pipeline, and the second impeller is located between the second pipe plug opening and the second circulation pipeline.

[0014] By adopting the above technical solution, the utility model has the following beneficial effects:

[0015] (1) The utility model is a high-efficiency axial-flow cooling pump with adjustable water temperature. By providing a temperature regulating body detachably connected to a casing, when the temperature regulating body fails, the temperature regulating body can be removed from the pump body for maintenance, which makes maintenance more convenient and it is also more convenient to replace the new temperature regulating body.

[0016] (2) The utility model provides a temperature regulating body and a double impeller rotating shaft. When the water inlet temperature rises, the temperature regulating body can drive the piston sleeve through the memory spring to open or close the size of the upper and lower water outlets, thereby changing the water flow in the pump body to different pipes.

The terminal temperature changes step by step, so that the memory spring is synchronously expanded and contracted, thereby adjusting the opening size of the piston sleeve. When the temperature rises, the flow rate of the pipe flowing through the cooling tower will increase, and when the temperature drops, the flow rate of the pipe flowing through the cooling tower will decrease, thereby achieving constant temperature control and effectively reducing energy consumption.

[0031] (Example)

[0032] See Figure 1 and Figure 2 A high-efficiency axial-flow cooling pump with adjustable water temperature comprises a pump body 1 and an adjusting device 2 detachably fixed inside the pump body 1; a rotating shaft 3 is inserted into the top of the pump body 1, and the pump body 1 and the rotating shaft 3 are rotatably sealed and sleeved, and a motor 5 is fixed outside the rotating shaft 3, and the motor 5 drives the rotating shaft 3 to rotate.

[0033] See Figure 3 , Figure 4 and Figure 5The regulating device 2 includes a shell 21, a piston sleeve 22 and a memory spring 23. The memory spring 23 is a nickel-titanium alloy spring. The shell 21 includes a top shell 21-1, a bottom shell 21-2 and a side wall shell 21-3. The bottom shell 21-2 and the side wall shell 21-3 are hollow structures; the top shell 21-1 is provided with a first pipe plug port 12-1, the inner cavity of the pump body 1 is provided with a second pipe plug port 12-2, and the pump body 1 is provided with a water inlet 11 between the first pipe plug port 12-1 and the second pipe plug port 12-2. The bottom shell 21-2 is provided with a through hole 21-4 for accommodating the piston sleeve 22, and the piston sleeve 22 is movably connected to the rotating shaft 3, and a first pipe plug 22-1 is fixed at one end of the piston sleeve 22, which is engaged with the first pipe plug port 12-1, and a second pipe plug 22-2 is fixed at the other end of the piston sleeve 22, which is engaged with the second pipe plug port 12-2; the memory spring 23 connects the bottom shell 21-2 and the first pipe plug 22-1, and the memory spring 23 drives the piston sleeve 22 to move axially between the first pipe plug port 12-1 and the second pipe plug port 12-2 along the rotating shaft 3 under the change of the water temperature of the water inlet 11. The piston sleeve 22 is sleeved in the rotating shaft 3, but does not rotate with the rotating shaft 3; the first pipe plug 22-1 is a disc plug, and is engaged with the first pipe plug port 12-1, and is limited by the first pipe plug port 12-1, so that the first pipe plug 22-1 can only move toward the second pipe plug port 12-2, and cannot exceed the top shell 21-1 of the regulating device 2.

[0034] The rotating shaft 3 passes through the first pipe plug opening 12-1 and the second pipe plug opening 12-2 in sequence; the first pipe plug opening 12-1 is connected to the first circulation pipeline 13-1, and the second pipe plug opening 12-2 is connected to the second circulation pipeline 13-2. The rotating shaft 3 is also fixed with a first impeller 4-1 and a second impeller 4-2. The first impeller 4-1 is located between the first pipe plug opening 12-1 and the first circulation pipeline 13-1, and the second impeller 4-2 is located between the second pipe plug opening 12-2 and the second circulation pipeline 13-2. The first impeller 4-1 and the second impeller 4-2 rotate in opposite directions. When the rotating shaft 3 rotates, the two impellers rotate in opposite directions at the same time, and the liquid discharged from the two pipe plug openings is pressurized and discharged to the external circulation pipeline.

[0035] Furthermore, a detachable stabilizing ring 6 is fixedly disposed inside the pump body 1 , and the rotating shaft 3 is rotatably connected to the stabilizing ring 6 , and the stabilizing ring 6 prevents the rotating shaft 3 from swinging inside the pump body 1 .

[0036] When in use, the first pipe plug port 12-1 is connected to the first circulation pipeline 13-1 passing through the cooling tower, and the second pipe plug port 12-2 is connected to the second circulation pipeline 13-2 directly flowing to the heat dissipation terminal.

[0037] Circulation starts. When circulating water passes through the water inlet 11, the water temperature is low, the memory spring 23 is in an extended state, the first pipe plug 22-1 of the piston sleeve 22 is completely fitted with the top shell 21-1 of the regulating device 2, the first pipe plug 22-1 closes the first pipe plug port 12-1, and the second pipe plug port 12-2 is completely opened, and the water flows through the second circulation pipe 13-2 for circulation.

[0038] As the temperature of the heat dissipation terminal increases, the water temperature of the return water inlet increases, the memory spring 23 slowly contracts, the first pipe plug 22-1 of the piston sleeve 22 separates from the first pipe plug port 12-1, and the first pipe plug port 12-1 gradually opens. Part of the water flows through the first circulation pipe 13-1 flowing through the cooling tower, and after being cooled by the cooling tower, it is sent to the heat dissipation terminal. At this time, the water in the first circulation pipe 13-1 and the second circulation pipe 13-2 merge, and the originally increased temperature is reduced here.

[0039] As the temperature of the heat dissipation terminal continues to rise, the water temperature returning to the water inlet 11 continues to rise, the memory spring 23 slowly contracts, the piston sleeve 22 and the first pipe plug 22-1 are completely separated from the first pipe plug port 12-1, and the first pipe plug port 12-1 of the pump body is fully opened; at this time, the second pipe plug 22-2 just completely closes the second pipe plug port 12-2, and all water flows out from the first circulation pipe 13-1, is cooled by the cooling tower, and is sent to the terminal.

[0040] In the above process, the terminal temperature is gradually increased, causing the memory spring to contract step by step, thereby adjusting the opening size of the piston sleeve and achieving a constant temperature cycle.

[0041] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
