Description

Technical Field

[0001] The present application relates to the technical field of boosting equipment, and in particular to a six-chamber RO booster pump. Background Art

[0002] Reverse osmosis (RO) pump is the core equipment of reverse osmosis water treatment system. It is mainly used to provide high pressure to drive water flow through the reverse osmosis membrane to achieve water purification.

[0003] The boosting principle of RO pump is to use the motor to drive the eccentric pump head to rotate, so that

[0004] The diaphragms corresponding to each chamber vibrate up and down, and under the action of the diaphragms, each chamber completes the water absorption and drainage processes through the cooperation of the one-way valves. When the RO pump is in use, the water flow in the pump head constantly impacts the inner wall of the pump head, causing the RO pump to emit a lot of noise and generate large vibrations. Summary of the Invention

[0005] In order to reduce the noise during water discharge, the present application provides a six-chamber RO booster pump.

[0006] The six-chamber RO booster pump provided in this application adopts the following technical solution:

[0007] A six-chamber RO booster pump comprises a pump casing, a pump head and a motor part, the pump head comprising a vibrating bottom diaphragm connected to the motor part, a vibrating top diaphragm sealingly mounted on the top of the vibrating bottom diaphragm and a one-way valve body mounted on the vibrating top diaphragm, a driving chamber being formed between the vibrating bottom diaphragm and the vibrating top diaphragm, the pump casing comprising a pump head casing for mounting the pump head, a drainage chamber communicating with a drainage hole being formed between the pump head casing and the vibrating top diaphragm, the pump head casing being provided with a noise reduction drainage structure in the drainage chamber, the noise reduction drainage structure comprising a plurality of groups of concentrically arranged guide rings and a cyclone arranged in the inner hole of the guide ring.

[0008] By adopting the above technical solution, the six-chamber RO booster pump sets a noise-reducing drainage structure in the drainage chamber. By utilizing the cooperation of multiple sets of concentrically arranged guide rings and cyclones, it can effectively guide the flow direction of the water, adjust the turbulent water flow into a uniform laminar flow, and reduce the direct impact of the water flow on the inner wall of the pump head shell, thereby achieving a noise reduction effect; the setting of the cyclone further optimizes the water flow path, so that the water is discharged in a spiral manner, reducing the occurrence of turbulence, thereby improving drainage efficiency and further reducing noise.

[0009] Optionally, three groups of guide rings are arranged at intervals along the axis of the motor part in the drainage chamber, and the inner diameters of the three groups of guide rings gradually decrease along the axis from the vibrating top diaphragm to the top of the pump cover. The guide rings are defined as the first guide ring, the second guide ring and the third guide ring from the bottom of the drainage chamber to the top of the drainage chamber, respectively. The bottom of the first guide ring has a first guide slope corresponding to the drainage hole of the drive chamber, the bottom of the second guide ring has a second guide slope for water flow impact, and the bottom of the third guide ring has a third guide slope for water flow impact.

[0010] By adopting this technical solution, three sets of guide rings are installed in the drainage chamber, with the inner diameter gradually decreasing from the vibrating top diaphragm to the top of the pump cover. This effectively guides the water flow into a stable vortex, reducing the noise and vibration caused by water impact. The first guide bevel corresponds to the drainage hole in the drive chamber, ensuring smooth water flow into the drainage chamber. The second and third guide bevels respectively guide the water flow twice and three times, further optimizing the water flow path and reducing the impact of the water flow, thereby significantly improving the noise reduction effect.

[0011] Optionally, a plug-in ring portion is provided on the outer side of the first guide ring and the third guide ring, and the pump head shell is provided with a plug-in ring groove for the plug-in ring portion to be embedded, and connecting rods are provided between the first guide ring and the second guide ring, and between the second guide ring and the third guide ring.

[0012] By adopting this technical solution, the first and third guide rings are provided with plug-in ring portions on their outer sides, which fit into the plug-in ring grooves on the pump head housing. This improves the stability of the guide ring installation and prevents them from shifting under the impact of water flow. The first, second, and third guide rings are connected by connecting rods, further enhancing the structural strength and integrity of the guide rings, ensuring their stability in high-speed water flow environments.

[0013] Optionally, sliding grooves are arranged at intervals on the plug-in ring portion, rotating balls that cooperate with the sliding grooves are arranged at intervals on the inner wall of the plug-in ring groove, and a locking component that controls the rotation of the guide ring is provided on the pump head cover.

[0014] By adopting this technical solution, the sliding groove on the plug-in ring cooperates with the rotating ball on the inner wall of the plug-in ring groove to achieve stable rotation of the guide ring within the pump head housing, while reducing friction during rotation. The guide ring rotates in the same direction as the water flow, adapting to the start and stop of the pump body's clearance, achieving dynamic adjustment.

[0015] The setting of the locking component can fix the position of the guide ring when needed, adapting to the working conditions of continuous high-pressure operation of the pump body.

[0016] Optionally, the locking assembly includes a lifting rod slidably installed on the pump head housing along the axis of the motor part, a driving part arranged at the end of the lifting rod, and a locking block slidably installed along the radial direction of the motor part, the locking block having a driving inclined groove for the driving part to pass through, a first locking surface being provided on the side of the locking block facing the plug-in ring part, and a second locking surface being provided on the outer wall of the plug-in ring part for locking with the first locking surface, and when the lifting rod moves toward the motor part, the driving part drives the locking block to slide radially toward the plug-in ring part.

[0017] By adopting the above-mentioned technical solution, the locking assembly can achieve reliable locking and unlocking of the guide ring. Specifically, the sliding movement of the lifting rod along the axis of the motor unit can drive the drive unit to move to the drive chute, and then use the elastic action of the compression spring to drive the locking block to slide toward the plug-in ring, so that the first locking surface and the second locking surface cooperate with each other, thereby fixing the position of the guide ring. When unlocking is required, the locking state can be released by reversing the operation, ensuring the rotational flexibility of the guide ring. This design improves the convenience and stability of the guide ring adjustment, while ensuring the reliability of the noise reduction and drainage structure during operation.

[0018] Optionally, the vibrating top membrane is further provided with a guide column at the axis of the drainage chamber for guiding water to flow upward. The guide column is fixedly connected to the vibrating top membrane, and the side wall of the guide column has a guide side surface consistent with the inclination direction of the first guide slope.

[0019] By adopting this technical solution, the guide column effectively guides water upward in a specific direction, reducing the possibility of water turbulence within the drainage chamber, thereby reducing noise and vibration caused by water impact. The guide side surface of the guide column's sidewall aligns with the inclination of the first guide slope, further optimizing the water flow path and ensuring a smoother flow within the drainage chamber, improving water discharge efficiency and reducing energy loss.

[0020] Optionally, the cyclone is arranged on the top of the third guide ring, and the cyclone and the guide column are coaxially arranged. The side wall of the cyclone is provided with a spiral guide groove for water flow, and the rotation direction of the spiral guide groove is opposite to the rotation direction of the motor part.

[0021] By adopting the above technical solution, the cyclone is arranged on the top of the third guide ring, which can effectively guide the water flow along a specific path. Under the action of the spiral guide groove, the water flow is forced to move along a counterclockwise path, forming a secondary vortex in the opposite direction of the vortex of the motor part. The positive vortex (generated by the motor part) and the reverse vortex (generated by the cyclone guide groove) collide with each other, and the kinetic energy is offset by friction and interference.

[0022] Optionally, a booster blade is rotatably mounted on the bottom of the cyclone, a blade driving member for driving the booster blade to rotate is provided at the bottom of the pump head housing, and an axial overlapping section exists between the booster blade and the third guide ring.

[0023] By adopting the above technical solution, the rotating installation of the booster blades and the axial overlapping design with the third guide ring can effectively improve the pressure and stability of the water flow. The booster blades accelerate the water flow from the guide ring to ensure that the water can be discharged from the drain hole.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] By arranging multiple sets of concentrically arranged guide rings and cyclones in the drainage chamber, the water flow is effectively guided to form an orderly flow, significantly reducing the noise and vibration caused by water impact;

[0026] The cyclone in the inner hole of the guide ring is combined with a guide slope with a specific inclination angle to optimize the water flow path, reduce the turbulence of the water flow, and further improve the noise reduction effect;

[0027] Under the action of the spiral guide groove, the water flow is forced to move along a counterclockwise path, forming a secondary vortex in the opposite direction of the vortex of the motor part. The positive vortex (generated by the motor part) and the reverse vortex (generated by the cyclone guide groove) collide with each other, and the kinetic energy is offset by friction and interference.

[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] The embodiment of the present application discloses a six-chamber RO booster pump.

[0036] Reference Figure 1 and Figure 2 A six-chamber RO booster pump includes a pump casing 1, a pump head 2 and a motor part 3. The pump head 2 includes a vibrating bottom diaphragm 21 connected to the motor part 3, a vibrating top diaphragm 22 sealed and installed on the top of the vibrating bottom diaphragm 21, and a one-way valve body 23 installed on the vibrating top diaphragm 22. A drive chamber 24 for water flow to enter is formed between the vibrating bottom diaphragm 21 and the vibrating top diaphragm 22, and the vibrating bottom diaphragm 21 and the vibrating top diaphragm 22 are sealed and fixed. The bottom of the vibrating bottom diaphragm 21 and the output shaft of the motor part 3 are eccentrically connected. In this embodiment, the pump head 2 is provided with six groups of independent drive chambers 24, and the six groups of drive chambers 24 are evenly spaced along the circumference of the output shaft of the motor part 3.

[0037] The pump housing 1 includes a pump head housing 11 for mounting the pump head 2 and a motor housing 12 connected to the pump head housing 11 and supplying power to the motor unit 3. The top of the vibrating top membrane 22 is sealed against the pump head housing 11, and the vibrating top membrane 22 divides the pump head housing 11 into two independent chambers. The two independent chambers include: a water inlet chamber 13 formed between the water inlet hole of the pump head housing 11 and the vibrating top membrane 22, and a drainage chamber 14 formed between the drainage hole of the pump body housing and the vibrating top membrane 22. The drainage chamber 14 is coaxial with the axis of the motor unit 3.

[0038] Both the water inlet chamber 13 and the drainage chamber 14 have through-holes connecting to the drive chamber 24. The vibrating top membrane 22 is equipped with one-way valves 23 at the through-holes connecting the drainage chamber 14 and the water inlet chamber 13, respectively. The two sets of one-way valves 23 control directions in opposite directions, controlling the one-way flow of water from the water inlet chamber 13 to the drive chamber 24 and from the drive chamber 24 to the drainage chamber 14. When the motor unit 3 rotates, the internal volume of the drive chamber 24 changes, achieving the intake and discharge of water.

[0039] Due to the high-speed rotation of the motor, the water flow has a greater impact force when it is transported from the drive chamber 24 to the drainage chamber 14, and the water flow impacts the drainage chamber 14 to generate a greater noise. In order to reduce the noise of the water flow hitting the top wall of the drainage chamber 14, the pump head housing 11 is provided with a noise reduction drainage structure 4 in the drainage chamber 14.

[0040] Reference Figure 2 and Figure 3 The noise reduction and drainage structure 4 includes three groups of concentrically arranged guide rings, a swirler 44 arranged in the inner hole of the guide ring, and a booster blade 45.

[0041] The three groups of guide rings are evenly spaced along the axis of the motor part 3, and the spacing between adjacent guide rings is 20-30 mm. The three groups of guide rings are defined as the first guide ring 41, the second guide ring 42 and the third guide ring 43 from the bottom of the drainage chamber 14 to the top of the drainage chamber 14. The inner diameters of the first guide ring 41, the second guide ring 42 and the third guide ring 43 gradually decrease. Among them, the bottom of the first guide ring 41 has a first guide slope 411 corresponding to the through hole of the vibrating top membrane 22 in the drainage chamber 14, the bottom of the second guide ring 42 has a second guide slope 421 corresponding to the top of the first guide ring 41, and the top of the third guide ring 43 has a third guide slope 431 corresponding to the top of the second guide ring 42.

[0042] All three sets of guide slopes are inclined upward, away from the vibrating top membrane 22. The first guide slope 411 is inclined at a 10° angle to the radial direction of the axis, the second guide slope 421 is inclined at a 20° angle to the radial direction of the axis, and the third guide slope 431 is inclined at a 30° angle to the radial direction of the axis. When water is ejected into the drainage chamber 14, it first strikes the first guide slope 411, initially reducing its velocity. The water then flows upward along the first guide slope 411, striking the second guide slope 421, reducing its velocity a second time. The water then flows upward along the second guide slope 421, striking the third guide slope 431, further reducing its velocity.

[0043] A guide column 25 is mounted on the vibrating top membrane 22 at the central axis of the drainage chamber 14. The guide column 25 is fixed to the vibrating top membrane 22 so that when the motor unit 3 is driven, it can drive the vibrating top membrane 22 and the guide column 25 to rotate synchronously. The height of the guide column 25 matches the height of the third guide ring 43. The sidewall of the guide column 25 has a guide side surface 251, which is inclined in the same direction as the first guide slope 411. The installation of the guide column 25 allows some water to be spirally transported upward along the guide side surface 251.

[0044] Reference Figure 2 、 Figure 4 and Figure 5 , the outer sides of the first guide ring 41 and the third guide ring 43 are provided with a plug-in ring portion 412, and the plug-in ring portion 412 and the guide ring are fixed by plug-in fitting. The pump head housing 11 is provided with a plug-in ring groove 111 for inserting the plug-in ring portion 412 on the inner wall of the drainage chamber 14, and the plug-in ring portion 412 and the plug-in ring groove 111 are rotatably fitted. The plug-in ring portion 412 is made of plastic material and has a certain deformation ability so that it can be snapped into the plug-in ring groove 111 to realize the installation of the guide ring. The first guide ring 41 and the second guide ring 42, and the second guide ring 42 and the third guide ring 43 are all fixed by a connecting rod 422, so that the three groups of guide rings form a whole.

[0045] A plurality of sliding grooves 413 are spaced along the axial direction on one end surface of the insert ring portion 412 of the third guide ring 43. Rotating ball heads 112 corresponding to the sliding grooves 413 are mounted on the inner wall of the insert ring groove 111 of the pump head housing 11. The rotating ball heads 112 are rotatably mounted, and connecting arc grooves (not shown) are provided between adjacent sliding grooves 413. When the multiple rotating ball heads 112 are arranged one after another in the sliding grooves 413, the water flow impacting the guide rings can drive the three groups of guide rings to rotate circumferentially.

[0046] The guide ring and the motor rotate in the same direction, which can adapt to the intermittent start and stop of the household water purifier and realize dynamic adjustment. At the same time, the rotating centrifugal force of the guide ring can separate some impurities and reduce blockage.

[0047] The pump head housing 11 is also provided with a locking assembly 15 for controlling the rotation of the plug-in ring portion 412. The locking assembly 15 includes a lifting rod 151, a driving portion 152, and a locking block 153. The lifting rod 151 is slidably mounted on the pump head housing 11, with its sliding direction parallel to the axis of the motor portion 3. One end of the lifting rod 151 extends through the top of the pump head housing 11 for the operator to pull. In this embodiment, four sets of lifting rods 151 are mounted on the pump head housing 11. The four sets of lifting rods 151 are circumferentially spaced along the axis of the pump housing 1, and adjacent lifting rods 151 are connected by an arcuate rod.

[0048] The driving portion 152 is integrally arranged at the other end of the lifting rod 151. The driving portion 152 is a rectangular block that is inclined with respect to the lifting rod 151. The locking block 153 is slidably installed in the pump head housing 11, and its sliding direction is perpendicular to the sliding direction of the lifting rod 151. The pump head housing 11 has a chamber for the locking block 153 to slide and is connected to the plug-in ring groove 111. The locking block 153 has a driving inclined groove 1531 for the driving portion 152 to pass through. The locking block 153 is also connected to a compression spring 154 on the side away from the plug-in ring portion 412. The compression spring 154 is in a compressed state under normal conditions. At this time, the driving inclined groove 1531 cooperates with the cylinder body of the lifting rod 151. The locking block 153 is provided with a first locking surface 1532 on the side facing the plug-in ring portion 412, and the outer wall of the plug-in ring portion 412 is provided with a second locking surface 414 that cooperates with the first locking surface 1532. When the lifting rod 151 is pulled upward, the driving portion 152 moves to the driving inclined slot 1531, causing the compression spring 154 to recover its deformation and drive the locking block 153 to slide toward the plug-in ring portion 412, thereby causing the first locking surface 1532 to abut and engage with the second locking surface 414.

[0049] The guide ring is locked under the locking assembly 15, which adapts to the working conditions of continuous high-load operation of the RO pump and ensures stable pressure.

[0050] Replay Figure 2 and Figure 3 The cyclone 44 is an inverted conical platform, with its base fixedly connected to the top wall of the inner cavity of the pump head housing 11. The outer wall of the cyclone 44 is circumferentially provided with at least two spiral guide grooves 441, which rotate in the opposite direction of the motor 3. Multiple sets of support arms 442 are circumferentially provided along the outer edge of the conical base of the cyclone 44, fixedly connected to the inner top wall of the pump housing 1.

[0051] A booster blade 45 is also rotatably mounted at the bottom of the cyclone 44. The booster blade 45 is located between the cyclone 44 and the guide column 25. The outer edge of the booster blade 45 intersects with the inner edge of the third guide ring 43, resulting in an axial overlap section 451 between the booster blade 45 and the third guide ring 43. A blade drive 46 is provided at the top of the pump housing 1 to drive the booster blade 45. The blade drive 46 is a micro motor whose output shaft extends vertically downward through the pump housing 1 and is fixed to the central axis of the booster blade 45. The inner cavity of the cyclone 44 has a sealed clearance groove for the output shaft of the blade drive 46. The direction of rotation of the booster blade 45 is consistent with that of the motor unit 3.

[0052] The implementation principle of a six-chamber RO booster pump in the embodiment of the present application is as follows: when water flows from the drive chamber 24 to the drainage chamber 14, the turbulent water flow is diffused and guided under the action of three groups of guide rings, so that the water flow is organized into a uniform laminar flow and the water flow velocity is reduced; the laminar water flow enters the booster blades 45, and the water flow is accelerated by the booster blades 45; the accelerated water flow forms a reverse water flow along the reverse spiral guide groove 441 of the cyclone 44, which offsets the forward water flow formed by the subsequent booster blades 45, reduces the flow velocity, and is finally guided to the drainage hole.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
