Description

TECHNICAL FIELD

[0001] The application belongs to the field of output pumps, and particularly relates to a high-pressure magnetic pump structure. BACKGROUND

[0002] Most of the liquid transmission structures adopt a transmission structure to drive a working diaphragm to move between a driving cavity and a liquid suction cavity, and the working diaphragm generates suction force and thrust after moving, thereby driving fluid to enter and discharge.

[0003] Currently, the reciprocating movement of the working diaphragm usually depends on mechanical structures for direct connection, and the friction and wear of the mechanical connection directly affect the service life of the working diaphragm, resulting in frequent maintenance and replacement, increased operating costs, in addition, the mechanical transmission system generates relatively large noise during operation, which causes discomfort and interference in some application occasions with strict requirements on noise, and the working diaphragm only bears the pressure of the liquid suction cavity on one side, and if the pressure is too large, the working diaphragm is prone to be pulled out or the diaphragm is prone to be burst, so that the working diaphragm bears relatively small pressure. SUMMARY

[0004] In order to overcome the defects of the prior art, the application provides a high-pressure magnetic pump structure to solve the problems that the reciprocating movement of the working diaphragm usually depends on mechanical structures for direct connection, the friction and wear of the mechanical connection directly affect the service life of the working diaphragm, resulting in frequent maintenance and replacement, increased operating costs, in addition, the mechanical transmission system generates relatively large noise during operation, which causes discomfort and interference in some application occasions with strict requirements on noise, and the working diaphragm only bears the pressure of the liquid suction cavity on one side, and if the pressure is too large, the working diaphragm is prone to be pulled out or the diaphragm is prone to be burst, so that the working diaphragm bears relatively small pressure.

[0005] One embodiment of the application provides a high-pressure magnetic pump structure for transmitting fluid, comprising:

[0006] a transmission shell, a liquid suction cavity, a liquid discharge cavity, a working cavity and a driving cavity arranged in the transmission shell;

[0007] a working diaphragm located in the working cavity and used for changing the volume of the working cavity to realize fluid suction and discharge, wherein one side of the working diaphragm facing the working cavity is a front surface, and the other side of the working diaphragm away from the working cavity is a back surface;

[0008] a magnetic transmission component located in the driving cavity and used for driving the working diaphragm to move to change the volume of the working cavity;

[0009] a balance pipeline having two ends respectively connected to the liquid discharge cavity and the back surface of the working diaphragm, and used for leading at least part of the pressure at the liquid discharge cavity to the back surface of the working diaphragm.

[0010] The high-pressure magnetic pump structure of the application drives the working diaphragm to reciprocate by magnetic transmission components, reduces the direct connection between the mechanical structure and the working diaphragm, thereby reducing the excessive wear of the working diaphragm, improving the service life and reliability of the equipment, and reducing the noise generated during operation compared with the traditional mechanical drive, which makes the equipment run more quietly. The general transmission structure design itself has good sealing performance, and the magnetic drive can reduce the risk of leakage, especially when handling corrosive or expensive fluids, which can better protect the fluid and the environment. The liquid suction cavity is used to input external fluid, the liquid discharge cavity is used to discharge fluid, and the drive cavity is used to install external transmission components, thereby generating suction and thrust to realize the entry and discharge of fluid. When the fluid enters, pressure is generated on one side of the working diaphragm, and when the pressure is too large, the diaphragm is prone to burst. At this time, the balance pipeline is connected between the liquid discharge cavity and the back of the working diaphragm, which will generate the same pressure on the back of the working diaphragm. After the pressure of the two is offset, the pressure bearing of the working diaphragm is improved.

[0011] In one embodiment, a separation structure is further included for forming a balance cavity between the back of the working diaphragm and the drive cavity, and the balance pipeline is connected to the balance cavity.

[0012] In one embodiment, the separation structure is a carbon fiber plate or a waterproof film.

[0013] In one embodiment, the magnetic transmission component includes a transmission assembly and a plurality of magnets.

[0014] The transmission assembly is installed on the transmission housing, and the transmission end of the transmission assembly is located in the drive cavity.

[0015] The plurality of magnets are installed in a regular array on the transmission end of the transmission assembly.

[0016] The number of working cavities is consistent with the working diaphragm.

[0017] In one embodiment, the working diaphragm includes a fixed part and an elastic part.

[0018] The fixed part is clamped on one side edge of the working cavity, and one side edge of the working cavity is provided with a clamping groove matched in size with the fixed part.

[0019] The elastic part is arranged on the fixed part, and the magnetic part is fixedly arranged on the side of the elastic part away from the fixed part.

[0020] The magnetic part is located on one side of each of the magnets, and the magnetic part is located on the motion track of each of the magnets.

[0021] In one embodiment, the working chamber is provided with a plurality of liquid inlet through holes and a plurality of liquid outlet through holes on one side.

[0022] In one embodiment, the working chamber is further provided with a liquid inlet control element on one side, which is located on one side of the liquid inlet through hole, for preventing backflow of fluid into the working chamber.

[0023] In one embodiment, the liquid outlet control element is provided on the liquid outlet chamber, which is located on one side of each of the liquid outlet through holes, for preventing backflow of fluid into the liquid outlet chamber.

[0024] In one embodiment, when the liquid inlet control element is opened, the working chamber is in communication with the liquid suction chamber;

[0025] When the liquid outlet control element is opened, the working chamber is in communication with the liquid outlet chamber.

[0026] In one embodiment, the balance pipeline includes a connecting pipe and a pressure relief valve.

[0027] One end of the connecting pipe is in communication with the liquid outlet chamber, and the other end of the connecting pipe is in communication with the driving chamber.

[0028] The pressure relief valve is installed on the connecting pipe.

[0029] The working chamber is at least two or more, and a plurality of working chambers are in communication with each other.

[0030] The high-pressure magnetic pump structure provided by the above technical solution has the following beneficial effects:

[0031] The magnetic force is relatively small, so the magnetic drive cannot provide high power. The use of high-cost super strong magnetic drive is not possible for the low magnetic force diaphragm to achieve high lift, as the working diaphragm cannot withstand high pressure. By introducing high pressure at the liquid outlet end to the back of the working diaphragm, a part of the front force of the balance working diaphragm is offset, so that the magnetic drive structure and the pressure balance structure cooperate to realize low magnetic force drive and also achieve high lift. The magnetic transmission component uses magnetic force to drive the working diaphragm to move reciprocally, reduces the direct connection of the mechanical structure and the working diaphragm, thereby reducing excessive wear on the working diaphragm, preventing the working diaphragm from being damaged and affecting the purity of the liquid, and improving the service life and reliability of the equipment. 3. Compared with the traditional mechanical drive, the magnetic drive produces less noise during operation. This makes the equipment run more quietly, which is suitable for use in environments sensitive to noise.

[0032] 4. The general liquid transfer structure design itself has good sealing performance, and the magnetic drive can reduce the risk of leakage, especially when handling corrosive or expensive fluids, which can better protect the fluids and the environment.

[0033] 5. The magnetic drive can be widely used in the delivery of various fluids, including high-viscosity fluids and particle suspensions, and has strong adaptability.

[0034] 6. The liquid suction chamber is used to input external fluid, the liquid discharge chamber is used to discharge fluid, and the drive chamber is used to install an external transmission assembly, so as to generate suction and thrust and realize the entry and discharge of fluid. When the fluid enters, the front surface of the working diaphragm generates pressure, and when the pressure is too large, the diaphragm is prone to burst. At this time, the balance pipeline is connected between the liquid discharge chamber and the back surface of the working diaphragm, so that the back surface of the working diaphragm generates the same pressure, and after the pressure of the two is offset, the pressure bearing capacity of the working diaphragm is improved.

[0035] 7. The pressure relief valve is used to adjust the pressure of the fluid entering the drive chamber, so that when the pressure of the front surface of the working diaphragm is consistent with the pressure of the back surface of the working diaphragm, the pressure bearing capacity of the working diaphragm is improved, and the pressure of the back surface of the working diaphragm can be controlled through the pressure relief valve. When the pressure of the back surface of the working diaphragm is greater than the pressure of the front surface of the working diaphragm, the front surface of the working diaphragm can bear higher pressure, rather than simply making the pressure of the front surface of the working diaphragm consistent with the pressure of the back surface of the working diaphragm. Therefore, the setting of the balance pipeline better improves the pressure bearing capacity of the working diaphragm.

[0036] 8. After balancing the pressure on both sides of the working diaphragm, the stress concentration generated on the working diaphragm can be reduced, the risk of material fatigue can be reduced, and the service life of the working diaphragm can be prolonged.

[0037] 9. After balancing the pressure on both sides of the working diaphragm, the movement of the working diaphragm can be more stable, so as to improve the stability of fluid delivery, avoid pulsating flow, and improve the uniformity of flow.

[0038] 10. After balancing the pressure on both sides of the working diaphragm, the energy waste can be reduced, the efficiency of the liquid transfer structure can be improved, and the energy consumption can be reduced. BRIEF DESCRIPTION OF DRAWINGS

[0061] In combination Figures 1 to 4 As shown in the drawings, one embodiment of the present application provides a high-pressure magnetic pump structure for transmitting fluid, comprising:

[0062] A transmission housing 100, and a liquid suction chamber 110, a liquid discharge chamber 120, a working chamber 140 and a driving chamber 130 arranged in the transmission housing 100;

[0063] A working diaphragm 400, the working diaphragm 400 is located in the working chamber 140, for changing the volume of the working chamber 140 to realize the suction and discharge of fluid, wherein the side of the working diaphragm 400 facing the working chamber 140 is the front surface, and the side away from the working chamber 140 is the back surface;

[0064] A magnetic transmission component 300, the magnetic transmission component 300 is located in the driving chamber 130, for driving the working diaphragm 400 to move, to change the volume of the working chamber 140;

[0065] A balance pipeline 200, two ends of the balance pipeline 200 are respectively communicated with the liquid discharge chamber 120 and the back surface of the working diaphragm 400, for leading at least part of the pressure at the liquid discharge chamber 120 to the back surface of the working diaphragm 400.

[0066] The high-pressure magnetic pump structure of the application drives the working diaphragm 400 to make reciprocating motion by magnetic force through the magnetic transmission component 300, reduces the direct connection between the mechanical structure and the working diaphragm 400, thereby causing excessive wear of the working diaphragm 400, improves the service life and reliability of the equipment, the noise generated during operation is generally lower compared with the traditional mechanical drive, which makes the equipment run more quietly, the general liquid transmission structure design itself has good sealing performance, and the leakage risk can be reduced through magnetic drive, especially when handling corrosive or expensive fluids, the fluid and the environment can be better protected; the liquid suction cavity 110 is used to input external fluid, the liquid discharge cavity 120 is used to discharge fluid, and the driving cavity 130 is used to install the external transmission assembly 310, so as to generate suction force and thrust, realize the entry and discharge of fluid, when the fluid enters, pressure is generated on one side of the working diaphragm 400, when the pressure is too large, the diaphragm is prone to burst, at this time, the liquid discharge cavity 120 and the back of the working diaphragm 400 are connected through the balance pipeline 200, which will cause the back of the working diaphragm 400 to generate the same pressure, and after the pressure of the two is offset, the pressure bearing of the working diaphragm 400 is improved.

[0067] It should be noted that the working diaphragm 400 is driven to make reciprocating motion by magnetic force through the magnetic transmission component 300, the direct connection between the mechanical structure and the working diaphragm 400 is reduced, thereby causing excessive wear of the working diaphragm 400, improving the service life and reliability of the equipment;

[0068] Magnetic control can realize more accurate motion control, the stroke and speed of the working diaphragm 400 can be adjusted, thereby better meeting the needs of fluid delivery, especially in applications requiring high-precision flow control;

[0069] Compared with the traditional mechanical drive, the noise generated during operation is generally lower. This makes the equipment run more quietly, which is suitable for use in environments sensitive to noise;

[0070] The general liquid transmission structure design itself has good sealing performance, and the leakage risk can be reduced through magnetic drive, especially when handling corrosive or expensive fluids, the fluid and the environment can be better protected;

[0071] Magnetic drive can be widely applied to the delivery of various fluids, including high-viscosity fluids and particle suspensions, and has strong adaptability;

[0072] After the pressure balance of the two sides of the working diaphragm 400, the stress concentration generated on the working diaphragm 400 can be reduced, the risk of material fatigue is reduced, thereby prolonging the service life of the working diaphragm 400;

[0073] The pressure balance on both sides of the working diaphragm 400 can make the movement of the working diaphragm 400 more stable, thereby improving the stability of fluid delivery, avoiding pulsating flow, and improving the uniformity of flow.

[0074] The pressure balance on both sides of the working diaphragm 400 can reduce energy waste, improve the efficiency of the liquid transmission structure, and help reduce energy consumption.

[0075] In one embodiment, a separation structure 600 is further included for forming a balance cavity 610 between the back of the working diaphragm 400 and the driving cavity 130, and the balance pipeline 200 is connected to the balance cavity 610.

[0076] The separation structure 600 is a carbon fiber plate or a waterproof membrane.

[0077] In this embodiment, the separation structure 600 is used to prevent fluid from entering the driving cavity 130, thereby producing a certain effect. The separation structure is a carbon fiber plate or a waterproof membrane, which is breathable. The generated pressure gas will directly enter the driving cavity 130, so that the waterproof membrane will not be squeezed and broken. When the fluid continues to flow out of the liquid discharge cavity 120, part of the fluid will also be carried out. The pressure of the working diaphragm 400 on the front surface is discharged at the same time and quickly transmitted to the back surface of the working diaphragm 400 through the balance pipeline 200, so that the pressure on both sides of the working diaphragm 400 tends to balance.

[0078] It should be noted that due to the breathability of the waterproof membrane, the pressure gas generated inside can directly enter the driving cavity 130 to maintain the necessary pressure, thereby avoiding the waterproof membrane from being squeezed and broken by excessive pressure and ensuring the integrity of the structure.

[0079] Further, the separation structure 600 can also not be installed, and the balance pipeline 200 directly connects the driving cavity 130 and the liquid discharge cavity 120. The pressure of the working diaphragm 400 on the front surface is discharged at the same time and quickly transmitted to the driving cavity 130 through the balance pipeline 200, and then the pressure is transmitted to the back surface of each working diaphragm 400 through the driving cavity 130, thereby realizing the pressure balance on both sides of the working diaphragm 400.

[0080] Further, because each working diaphragm 400 is provided with a separation structure 600, each balance cavity 610 is connected with a connecting pipe 210, and the other end of the connecting pipe 210 is connected with the liquid discharge cavity 120, which is described herein.

[0081] In one embodiment, the magnetic transmission component 300 includes a transmission assembly 310 and a plurality of magnets 320.

[0082] The transmission assembly 310 is mounted on the transmission housing 100, and a transmission end of the transmission assembly 310 is located in the driving cavity 130.

[0083] The plurality of magnets 320 are regularly arranged on the transmission end of the transmission assembly 310.

[0084] The number of the working cavities 140 is consistent with the working diaphragm 400.

[0085] The working diaphragm 400 comprises a fixed part 410 and an elastic part 420.

[0086] The fixed part 410 is clamped on one side edge of the working cavity 140, and the one side edge of the working cavity 140 is provided with a clamping groove matched with the size of the fixed part 410.

[0087] The elastic part 420 is arranged on the fixed part 410, and the magnetic member 500 is fixedly arranged on a side of the elastic part 420 away from the fixed part 410.

[0088] The magnetic member 500 is located on one side of each of the magnets 320, and the magnetic member 500 is located on the motion track of each of the magnets 320.

[0089] In the embodiment, the transmission assembly 310 drives the magnets 320 to rotate. When the magnets 320 rotate to above the magnetic member 500, the magnetic poles of the magnets 320 and the magnetic member 500 are communicated, and the two repel each other, so as to press the working diaphragm 400 by repulsive force. When the magnets 320 move away from the magnetic member 500, the elastic part 420 of the working diaphragm 400 rebounds, the next magnet 320 moves to the magnetic member 500 again, and the working diaphragm 400 repeats the above steps to make reciprocating motion, so as to generate suction force and thrust force of the working diaphragm 400, thereby transmitting the fluid.

[0090] It should be noted that the separation structure 600 does not affect the transmission of the magnets 320 and the magnetic member 500, which is described herein.

[0091] In one embodiment, one side of the working cavity 140 is provided with a plurality of liquid inlet through holes 141 and a plurality of liquid outlet through holes 143.

[0092] One side of the working cavity 140 is further provided with a liquid inlet control member 142, and the liquid inlet control member 142 is located on one side of the liquid inlet through hole 141, so as to prevent the fluid from flowing back after entering the working cavity 140.

[0093] The liquid outlet control member 144 is arranged on the liquid outlet cavity 120, and the liquid outlet control member 144 is located on one side of each of the liquid outlet through holes 143, so as to prevent the fluid from flowing back after entering the liquid outlet cavity 120.

[0094] When liquid is being taken in, the liquid-taking control member 142 is opened, and at this time the working chamber 140 is in communication with the liquid-absorbing chamber 110;

[0095] When liquid is being taken out, the liquid-taking control member 144 is opened, and at this time the working chamber 140 is in communication with the liquid-discharging chamber 120.

[0096] In this embodiment, when the working diaphragm 400 is far away from the working chamber 140, the liquid-taking control member 142 is opened by the pressure of the fluid, so that the fluid enters the working chamber 140 from the liquid-absorbing chamber 110 through the liquid-taking through hole 141. After entering the working chamber 140, the liquid-taking control member 142 is in an arc structure, and the arc surface of the liquid-taking control member 142 is in close contact with one side of the working chamber 140 and located at one side of the liquid-taking through hole 141, so that the arc surface is opened by the pressure of the fluid and enters the working chamber 140, and the other surface of the arc structure is in close contact with one side of the working chamber 140 after being pressed by the pressure, so that the fluid is prevented from flowing back to the liquid-absorbing chamber 110 (similar to a one-way valve). Similarly, when the working diaphragm 400 is pressed into the working chamber 140, the fluid is pressed to the liquid-taking through hole 143, the liquid-taking control member 144 is also in an arc structure, and the arc surface of the liquid-taking control member 144 is in close contact with one side of the liquid-discharging chamber 120 and located at one side of the liquid-taking through hole 143, so that the arc surface is opened by the pressure of the fluid and enters the liquid-discharging chamber 120 and is discharged, and the other surface of the arc structure is in close contact with one side of the liquid-discharging chamber 120 after being pressed by the pressure, so that the fluid entering the liquid-discharging chamber 120 is prevented from flowing back (similar to a one-way valve).

[0097] In one embodiment, the balance pipeline 200 includes a connecting pipe 210 and a pressure relief valve 220;

[0098] One end of the connecting pipe 210 is in communication with the liquid-discharging chamber 120, and the other end of the connecting pipe 210 is in communication with the driving chamber 130;

[0099] The pressure relief valve 220 is installed on the connecting pipe 210;

[0100] The working chamber 140 is at least two or more, and a plurality of working chambers 140 are in communication with each other.

[0101] In this embodiment, the pressure relief valve 220 is used to adjust the pressure of the fluid entering the driving chamber 130. When the pressure of the fluid in the driving chamber 130 is consistent with the pressure in the liquid-absorbing chamber 110, the pressure-bearing capacity of the working diaphragm 400 can be improved, and by increasing the pressure of the driving chamber 130 through the pressure relief valve 220, the side of the working diaphragm 400 in contact with the liquid-absorbing chamber 110 can bear higher pressure, rather than simply making the pressure of the fluid in the driving chamber 130 consistent with the pressure in the liquid-absorbing chamber 110, so that the balance pipeline 200 better improves the pressure-bearing capacity of the working diaphragm 400.

[0102] It should be noted that, Figures 1-4 The connecting pipeline between the balance pipeline 200 and the balance cavity 610 is not shown in the middle and can be added later.

[0103] Further, when the working cavity 140 is multiple, when conveying liquid that needs to be mixed, after the liquid enters the working cavity 140, the liquid will flow into each working cavity 140 through the communication of multiple working cavities 140, and then the liquid will rotate in the working cavity 140 when the liquid is sucked by pressure. This will increase the mixing degree of the liquid.

[0104] The working principle of the present application is:

[0105] The magnetic transmission component 300 drives the working diaphragm 400 to move reciprocally by magnetic force, reduces the direct connection between the mechanical structure and the working diaphragm 400, thereby causing excessive wear to the working diaphragm 400, improves the service life and reliability of the equipment, and the magnetic drive generally produces lower noise than the traditional mechanical drive when running, which makes the equipment run more quietly. The liquid transmission structure design itself has good sealing performance, and the magnetic drive can reduce the risk of leakage, especially when handling corrosive or expensive fluids, which can better protect the fluids and the environment; the liquid suction cavity 110 is used to input external fluid, the liquid discharge cavity 120 is used to discharge fluid, and the driving cavity 130 is used to install the external transmission assembly 310, thereby generating suction and thrust to realize the entry and discharge of fluid. When the fluid enters, the side of the working diaphragm 400 will generate pressure, and when the pressure is too large, the diaphragm is easy to burst. At this time, the balance pipeline 200 is connected between the liquid discharge cavity 120 and the back of the working diaphragm 400, which will generate the same pressure on the back of the working diaphragm 400. After the pressure of the two is offset, the pressure bearing of the working diaphragm 400 is improved.

[0106] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made by using the paper content and the drawings of the present application, or direct / indirect application in other related technical fields under the inventive concept of the present application is included in the patent protection scope of the present application.
