Description

Technical Field

[0001] This invention relates to the field of circulating pumps, and more particularly to a refrigerant pump. Background Technology

[0002] Refrigerant pumps are mainly used in the refrigeration industry for pressurizing and transporting refrigerants at atmospheric pressure. They are compatible with various refrigerants such as R22, R134a, R407C, and R410A. In central processing systems, long-distance refrigerant transmission is achieved by establishing a central delivery and booster station. When the outside gas temperature decreases, the pump can perform heat exchange without the compressor operating. At this time, the refrigerant pump forces the internal refrigerant to circulate along the pipeline system, cooling the central processing system area. The refrigerant pump can be frequency-controlled according to refrigeration needs to achieve different refrigerant flow rates, ensuring stable cooling of the central processing system.

[0003] Existing refrigerant pumps, under specific working conditions, are subjected to the scouring of irregularly flowing refrigerant and the disturbance of gases escaping from the refrigerant itself during the flow process. This causes the entire refrigerant to become chaotic during the flow process, resulting in impact on the pipeline and significant wear on the refrigerant pump. During this process, it also generates considerable noise, affecting the surrounding environment. Summary of the Invention

Simultaneously, the connecting mechanism enables significant gas-liquid separation, reducing gas explosions in the subsequent pipeline system. The combination of these two mechanisms drives stable fluid flow, reducing impact on equipment and other forms of wear, lowering overall system noise, and extending the system's stable operating life.

[0018] This invention, through its variable blades, can quickly respond to flow rate demands. Simultaneously, by coordinating with fluid backflow, it reduces the pressure difference between the front and rear ends of the pump body, further reducing irregular stress on the support components, thereby extending the service life of the device.

Detailed Implementation

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example 1: Please refer to Figures 1-8 ,

[0031] A refrigerant pump includes a sealed housing 01 and an auxiliary cylinder 02 welded together. A flow-slowing mechanism is installed inside the auxiliary cylinder 02 to mitigate refrigerant surge. This mechanism reduces noise in the gas-liquid mixture of refrigerant, minimizing irregular impacts and ensuring stable operation of the pump, thus extending its lifespan. A connecting mechanism is located on one side of the flow-slowing mechanism between the sealed housing 01 and the auxiliary cylinder 02, and the other side of the connecting mechanism is connected to a pumping mechanism located inside the sealed housing 01. The connecting mechanism connects the pumping mechanism and the flow-slowing mechanism, acting as a connection and transmission mechanism. The pumping mechanism forces liquid flow, forming a fluid circulation. A processing mechanism is located outside the pumping mechanism inside the sealed housing 01. This processing mechanism compresses and guides the gas within the housing, handling the internal gas and changing its form, reducing long-term wear caused by internal gas explosions and further improving overall operational stability.

[0032] The flow-regulating mechanism includes a flow-expanding sleeve 29 disposed within an auxiliary cylinder 02. A sealing plug 05 is fixedly and slidably fitted inside the flow-expanding sleeve 29. The other end of the sealing plug 05 is fixedly connected to a moving tube 06 and a support tube 07, which are nested together. A flow-dividing plate 26, fixedly connected to the auxiliary cylinder 02, is slidably fitted onto the outside of the support tube 07. A functional column 09 is connected to the other side of the flow-dividing plate 26, and a rotatable swing fan blade 25 is connected to the functional column 09. Multiple irregularly shaped through-holes are provided on the flow-dividing plate 26, the flow-expanding sleeve 29, and the swing fan blade 25. These irregular through-holes can partially obstruct the chaotic flow of fluid, thus streamlining its disordered mechanical energy. The irregular shapes can be elliptical, polygonal, or combinations of multiple basic shapes, depending on specific design requirements. The liquid flowing through the holes instantly takes on different shapes. Under the action of multiple different shapes, the internal stress will be reduced by probability, reducing the irregular stress of the liquid. Then, it overflows into the auxiliary cylinder 02 through the expansion sleeve 29, and then passes through the secondary obstruction of the flow divider 26 for rectification again, reducing the chaotic impact force. At the same time, under the action of the fluid, the functional column 09 and the flow divider 26 rotate, allowing the fluid to mix further, thereby eliminating the internal chaotic stress. The angle of the swing fan blade 25 can be adjusted to the fluid velocity and different impacts to produce a certain angle of swing. At the same time, in conjunction with the through hole 1, the impact and irregular mixing of the fluid are balanced, eliminating surge. At the same time, it can disperse and float the gas in the coolant, assisting in gas-liquid separation or promoting the dispersion of gas in the liquid.

[0033] The flow-slowing mechanism also includes multiple intercepting meshes 28 disposed on one side of the flow-expanding sleeve 29. These meshes are used to filter some sticky or strip-shaped impurities while the coolant flows, preventing impeller entanglement or hole blockage. The intercepting meshes 28 are made of flexible material and can be pulled out after deformation through the inlet pipe 04. A flow-stopping and stabilizing plate 46, which is fixedly connected to the sealed box 01, is also fixedly connected to the outside of the flow-expanding sleeve 29. The moving pipe 06 can slide inside the support pipe 07. Multiple fixed sleeves 43 are fixedly connected to one side of the flow-dividing plate 26. A moving guide tube 44 is slidably fitted inside the fixed sleeve 43, and one end of the moving guide tube 44 is fixedly connected to a blocking pipe. The blocking pipe has multiple irregularly shaped through holes. A spring is disposed inside the support pipe 07, and the other end of the spring is fixedly connected to the moving guide tube 44. Under normal operating conditions, the fluid moves instantaneously. After movement, it will impact the sealing plug 05. When the flow rate is high, the sealing plug 05 moves, expanding the passage length of the top air guide pipe 39, that is, generating a faster flow rate through multiple through holes. When the flow-expanding sleeve 29 is fully connected, the flow rate continues to increase. The fluid pressure forces the moving guide pipe 44 to move, and then overflows through the auxiliary bucket 27 to the other side of the auxiliary cylinder 02, ensuring the rapid flow of coolant. The outer side of the blockage pipe is slidably fitted with the auxiliary bucket 27, which is fixedly connected to the flow-stopping stabilizing plate 46. The support pipe 07 is slidably fitted with the connecting pipe 08, and the other end of the connecting pipe 08 is rotatably connected to the functional column 09. The outer side of the functional column 09 is connected to the buffer cylinder 23, which is connected to the swing fan blade 25. The connecting pipe 08 is used to support the functional column 09 and ensure the rotation of the functional column 09. The buffer cylinder 23 can control the rotation of the corresponding swing fan blade 25 to adapt to the control of the fluid.

[0034] The support tube 07 is filled with damping fluid, and one end of the connecting tube 08 is rotatably connected to a rotating ring. A spring connected to the support tube 07 is fixedly connected to one side of the rotating ring. The damping fluid buffers the impact generated when the fluid enters, thereby reducing the overall vibration and ensuring the movement of the sealing plug 05 to adapt to changes in flow rate. The spring is used to return the support tube 07 to its original position.

[0035] A transmission column 24 is connected to the top of the buffer cylinder 23. The transmission column 24 is connected to the oscillating fan blade 25, and one end of the transmission column 24 extends into the buffer cylinder 23. An electromagnet is fixedly connected to the inner wall of the buffer cylinder 23, and multiple fan-shaped paddles located inside the buffer cylinder 23 are fixedly connected to the outer side of the transmission column 24. The buffer cylinder 23 is filled with a viscous liquid. By adjusting the strength and direction of the electromagnet, the rotation angle of the transmission column 24 can be controlled, that is, the tilt angle of the oscillating fan blade 25 relative to the flow direction, so as to achieve artificial control of the flow rate. Furthermore, through the magnet and the viscous liquid, the oscillating fan blade 25 can be buffered during impact, reducing the impact energy of irregular liquid and increasing the stability of the coolant flow.

[0036] The implementation principle of this application embodiment is as follows: During operation, the coolant flows under the action of the pumping mechanism. First, it passes through the intercepting mesh 28 to perform simple filtration on some sticky or strip-shaped impurities. The fluid overflows into the auxiliary cylinder 02 through the expansion sleeve 29. Through multiple irregular through holes 2, the mixed and chaotic fluid can be blocked to a certain extent, and its chaotic mechanical energy can be sorted out to a certain extent. Then, it passes through the secondary blocking of the flow divider 26 and is rectified again to reduce the chaotic impact force. At the same time, under the action of the fluid, the functional column 09 and the flow divider 26 rotate, so that the fluid can be further mixed, thereby eliminating the internal chaotic stress. The angle of the oscillating fan blade 25 is adapted to the fluid flow rate and different impacts to produce a certain angle of oscillation. At the same time, in conjunction with the through hole 1, the impact of the fluid and the irregular mixing are balanced, eliminating surge, thereby reducing impact and operating noise. At the same time, it can disperse and float the gas in the coolant, assisting in gas-liquid separation or promoting the dispersion of gas in the liquid.

[0037] Example 2:

[0038] Combination Figures 1-4 This embodiment is an improvement on embodiment 1, further described in the following aspects:

[0039] The connecting mechanism includes a return pipe 11 rotatably connected to the functional column 09. A stabilizing sleeve 33 is rotatably sleeved on the outside of the return pipe 11, and a half-section ventilated arc 31 located on the return pipe 11 is fixedly connected to the outside of the stabilizing sleeve 33. The return pipe 11 is used to support the functional column 09 and stabilize the corresponding pumping mechanism. The stabilizing sleeve 33 is fixedly connected to the guide shroud 12 via a rod. The half-section ventilated arc 31 can guide the fluid and assist in separating some gas. The gas overflows into the closed box 01 through the guide shroud 12 for subsequent processing. The guide shroud 12 is provided on the outside of the half-section ventilated arc 31, and the outer edge of the guide shroud 12 is engaged with the auxiliary cylinder located on the closed box 01. The auxiliary sealing sleeve 30 at the joint 02 has a fixed sleeve 43 connected to one end of the return pipe 11. One end of the fixed sleeve 43 is connected to the pumping mechanism. The bottom of the guide shroud 12 is also connected to a horizontal suction pipe 32, and the other end of the horizontal suction pipe 32 is connected to a vertically arranged vertical suction pipe 34. The vertical suction pipe 34 is connected to the pumping mechanism. The auxiliary sealing sleeve 30 provides auxiliary sealing for the closed box 01 and the auxiliary cylinder 02, ensuring that the entire device is in a sealed state and preventing the inflow of external impurities. When the pumping mechanism generates negative pressure, the fluid can flow through the horizontal suction pipe 32 and the vertical suction pipe 34, thereby sealing the pumping mechanism from running dry.

[0040] The upper sides of the flow guide shroud 12 and the half-section ventilated arc 31 are provided with multiple vent holes for gas passage, and the return pipe 11 is provided with multiple return holes. The inner wall of the sealed box 01 is provided with an annular groove that cooperates with the auxiliary sealing sleeve 30. The vent holes are used for gas flow, and the return holes are used for liquid return, reducing the internal and external pressure difference, thereby stabilizing the pumping mechanism and reducing the wear of bearings, etc.

[0041] Example 3:

[0042] Combination Figures 1-6 This embodiment is an improvement on embodiment 1, further described in the following aspects:

[0043] The pumping mechanism includes a pump casing 22 disposed in the middle of the enclosed box 01. A return sleeve 17 is fixedly connected to one end of the pump casing 22, and a balance drum 37 is slidably sleeved inside the return sleeve 17. A transmission hollow shaft 42 is sleeved in the middle of the balance drum 37. The pump casing 22 is used for guiding the fluid. During the flow of coolant, part of the coolant enters the return sleeve 17 through the gap between the balance drum 37 and the transmission hollow shaft 42, and then returns to the front end through the transmission hollow shaft 42, the moving shaft 14, and the return pipe 11, thereby reducing the axial static force of some bearings and reducing friction. To prevent friction and wear, a movable shaft 14 is slidably sleeved at the other end of the hollow shaft 42 in the transmission. Two guide sleeves 13 are sleeved on the outside of the movable shaft 14. Multiple rotating blades 47 are rotatably connected to the guide sleeves 13 via spring hinges. One end of the movable shaft 14 is connected to the fixed sleeve 43. After the water flows through the fixed sleeve 43, it is dispersed radially. At this time, the high-speed rotating blades 47 generate a pressure difference, thereby realizing the pumping of liquid. In addition, with the increase of rotation speed, the rotating blades 47, under the action of centrifugal force, have a larger unfolded area relative to the guide sleeves 13, generating pressure. The increased strength difference leads to a faster increase in the overall coolant flow rate, meeting the cooling requirements. Support frames 40 are fitted onto the outer sides of both the hollow drive shaft 42 and the moving shaft 14, and these support frames 40 are fixedly connected to the enclosed box 01. An elastic component 15 is connected to one side of the support frame 40 on the hollow drive shaft 42, and the other end of the elastic component 15 is connected to the support frame 40 on the moving shaft 14. The support frame 40 on the moving shaft 14 is slidably fitted onto the moving shaft 14. A partition plate 38 is also connected to the outer side of the return sleeve 17. One side of 38 is connected to a drain pipe 03, which extends to the outside of the closed box 01. A rotor 16 is fixedly connected to the outside of the transmission hollow shaft 42. A stator 21 fixedly connected to the pump casing 22 is provided on the outside of the rotor 16. The support frame 40 is supported based on the transmission hollow shaft 42 and the moving shaft 14. At the same time, under the action of the elastic component 15, the guide sleeve 13 and the moving shaft 14 can move synchronously within a certain range, thereby reducing the damage of instantaneous impact to the guide sleeve 13 and the transmission hollow shaft 42, and further improving the stability of the entire device.

[0044] One end of the vertical suction pipe 34 is connected to the pump housing 22, and the pump housing 22 and the vertical suction pipe 34 are in communication. A one-way valve is provided at the bottom of the vertical suction pipe 34 to control the flow direction of the liquid. The stable mounting sleeve 33 is fixedly connected to the pump housing 22 by a rod. The guide sleeve 13 is provided with a through groove for the movement of the rotating blade 47, and the rotating blade 47 and the guide sleeve 13 are in clearance fit. The through groove can ensure the movement of the rotating blade 47 under the action of centrifugal force.

[0045] The implementation principle of this application embodiment is as follows: During operation, the rotor 16 and stator 21 cause the transmission hollow shaft 42 to rotate, which in turn drives the moving shaft 14 and the guide sleeve 13 to rotate. Simultaneously, multiple rotating blades 47 on the guide sleeve 13 rotate, generating a pressure difference to achieve forced flow of coolant and realize coolant circulation. The rotating blades 47 can unfold at different angles at different speeds, which can quickly increase or decrease the flow rate to meet the coolant flow requirements of the cooling system. At the same time, during the flow of coolant, some coolant enters the return sleeve 17 through the gap between the balance drum 37 and the transmission hollow shaft 42, and then returns to the front end through the transmission hollow shaft 42, the moving shaft 14, and the return pipe 11. This reduces the axial static force of some bearings and reduces friction and wear. The guide sleeve 13 and the moving shaft 14 can move synchronously within a certain range, thereby reducing the damage to the guide sleeve 13 and the transmission hollow shaft 42 caused by instantaneous impacts and further improving the stability of the entire device.

[0046] Example 4: Combination Figures 1-8 This embodiment is an improvement on embodiment 1, further described in the following aspects:

[0047] The processing mechanism includes a transmission assembly 35 that is driven by the return pipe 11, and a speed change assembly 36 that is driven by the other end of the transmission assembly 35. A micro compressor is driven by the output end of the speed change assembly 36. The micro compressor can be a compression device from the prior art, which can compress the absorbed gas into a liquid and discharge it in one direction. The power source for the micro compressor can be directly connected to a power source or transmitted through the transmission assembly 35 and the speed change assembly 36. The transmission assembly 35 and the speed change assembly 36 transmit the torque of the return pipe 11. Both the transmission assembly 35 and the speed change assembly 36 are combinations of existing mechanisms, namely gears, worm gears, drive shafts, etc., to achieve transmission. (The last sentence appears to be incomplete and possibly refers to a closed box.) A partition plate is fixedly connected in the middle of the 01 enclosure, dividing the enclosure 01 into two chambers: a gas storage chamber 20 and a liquid storage chamber 18. The micro compressor is located in the gas storage chamber 20. One side of the partition plate is connected to a liquid pipe 19 extending to the bottom of the liquid storage chamber 18 and a top air guide pipe 39 extending to the top of the gas storage chamber 20. Gas is guided into the gas storage chamber 20 through the top air guide pipe 39, and heavier liquid is guided into the liquid storage chamber 18 through the liquid pipe 19. The bottom of the liquid pipe 19 is submerged in liquid, thereby reducing the secondary entry of gas. At the same time, the gas in the liquid storage chamber 18 can be returned to the gas storage chamber 20 through the top air guide pipe 39, further ensuring gas processing.

[0048] A raised groove is connected to one side of the enclosed box 01. The micro compressor is located in the raised groove. Multiple AC pipes that pass through the raised groove are connected to the raised groove. An inlet pipe 04 is connected to one side of the auxiliary cylinder 02. The raised groove is used to extend the space and place the micro compressor in the outside. This allows the heat generated by the micro compressor during operation to be transferred to the outside through the AC pipes, preventing the internal coolant from heating up and reducing the efficiency of gas compression.

[0049] The implementation principle of this application embodiment is as follows: During operation, through the transmission component 35 and the speed change component 36 or the direct power supply from the outside, and in conjunction with the flow of the one-way pipe, the gas in the liquid storage chamber 18 is compressed into liquid under the action of the micro compressor, and enters the space of the liquid storage chamber 18 through the liquid pipe 19. The gas pressure in the gas storage chamber 20 is reduced synchronously, so that the gas of the coolant after being stabilized by the auxiliary cylinder 02 can quickly overflow from the liquid and re-enter the liquid storage chamber 18 through the guide shroud 12, thereby ensuring the stability of the fluid, reducing the damage of gas explosion to the device, and further extending the service life of the device while reducing operating noise and vibration.

[0050] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
