TECHNICAL FIELD

[0002] A pump is a machine for delivering fluid or pressurizing fluid, which transmits mechanical energy or other external energy to liquid to increase the energy of the liquid. The pump is mainly used to deliver liquid such as water, oil, acid-base liquid, emulsion, suspension emulsion and liquid metal, and can also deliver liquid-gas mixture and liquid containing suspended solid. The pump can be classified into three types according to working principle, i.e. volumetric pump, dynamic pump and other type pump. In addition, the pump can be classified and named according to other methods, such as electric pump and water wheel pump according to driving method, single-stage pump and multi-stage pump according to structure, boiler feed water pump and metering pump according to use, and water pump, oil pump and mud pump according to the nature of the delivered liquid. According to whether there is a shaft structure, the pump can be classified into linear pump and traditional pump. The water pump can only deliver fluid medium, but cannot deliver solid. However, the pump will vibrate during operation, and long-term vibration will reduce the service life of the pump and motor.

The cavities in the rubber layers are provided with second springs, which dampen the vibration of the shell.

[0044] Secondly, "one embodiment" or "embodiment" referred to herein means that a specific feature, structure or characteristic can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in this specification does not mean the same embodiment, nor is it an embodiment that is separate or alternative to other embodiments.

[0045] Embodiment 1

[0046] Reference Figures 1-4 For the first embodiment of the present application, the embodiment provides a vertical pump with a self-compensation thrust balancing device.

[0047] Specifically, it includes:

[0048] The bearing mechanism 100 comprises a bearing base 101 for bearing, a vertical pump body 102, and a motor 103 for driving the vertical pump body 102;

[0049] The compensation adjusting mechanism 200 is used for changing a damping angle according to a vibration amplitude of the vertical pump body 102 and damping the vertical pump body 102;

[0050] The negative pressure transmission mechanism 300 is used for adaptively adjusting the damping angle of the compensation adjusting mechanism 200 according to the speed of the driving end of the motor 103;

[0051] The compensation adjusting mechanism 200 and the negative pressure transmission mechanism 300 are fixedly installed on the upper end surface of the bearing base 101, the vertical pump body 102 is hingedly installed on the compensation adjusting mechanism 200, the vertical pump body 102 and the motor 103 are fixedly connected through a flange, and the vertical pump body 102 is provided with a water inlet and a water outlet.

[0052] The compensation adjusting mechanism 200 comprises a damping assembly 202 and a compensation adjusting assembly;

[0053] The damping assembly 202 is used for damping the vibration force generated by the motor 103 driving the vertical pump body 102 through a double-layer damping mode, and the compensation adjusting assembly is used for adjusting the included angle between two damping assemblies 202 close to each other in the transverse direction and adjusting the longitudinal distance between the vertical pump body 102 and the bearing base 101 according to the speed of the driving end of the motor 103.

[0054] The damping assembly 202 comprises a connecting seat 2021, a cylinder 2022 fixedly arranged on the connecting seat 2021, a sliding groove 2036 arranged in the cylinder 2022, a through hole arranged on the cylinder 2022, a connecting column 2023 slidably arranged on the cylinder 2022 through the through hole and the sliding groove 2036, a spring 2025 arranged in the sliding groove 2036 of the cylinder 2022 and used for compensating the restoring force of the connecting column 2023, the two ends of the spring 2025 being connected to the connecting column 2023 and the connecting seat 2021 respectively, the connecting seat 2021 and the connecting column 2023 being provided with shoulder portions, the spring 2024 being arranged between the shoulder portions of the connecting seat 2021 and the connecting column 2023, the spring 2024 being sleeved on the outer circumferential surface of the connecting column 2023, and the top of each connecting column 2023 being hingedly connected to the vertical pump body 102.

[0055] Wherein, in the damping assembly 202, when the motor 103 drive end speed is too large, the vibration force generated by the vertical pump body 102 can make the connecting column 2023 be subjected to extrusion force, which drives the connecting column 2023 to slide in the sliding groove 2036 of the cylinder body 2022. Between the sliding, the extrusion force of the connecting column 2023 first overcomes the elastic force of the spring one 2024 sleeved on the outer circumferential surface of the connecting column 2023. When the elastic force of the spring one 2024 is overcome, the extrusion force needs to overcome the elastic force of the spring two 2025 again. The damping assembly 202 is an assembled integral structure, so that the extrusion force of the connecting column 2023 can be reduced by the spring one 2024 and the spring two 2025 in the process of continuous shaking of the vertical pump body 102. Therefore, when the motor 103 drive end speed is too large, the vibration force generated by the vertical pump body 102 can be reduced by the damping assembly, effectively protecting the internal elements of the vertical pump body 102, preventing the internal elements from being damaged due to excessive vibration of the vertical pump body 102;

[0056] The bearing base 101 is symmetrically provided with a sliding groove. The compensation adjusting assembly comprises a compensation assembly 201 and an adjusting assembly 203. The compensation assembly 201 comprises mounting seats 2012 symmetrically arranged on the bearing base 101 and corresponding to the sliding grooves 2036. Each mounting seat 2012 is fixedly provided with an air pump 2011. The bearing base 101 is also fixedly provided with a compensation air cylinder 2014. The compensation air cylinder 2014 is communicatively provided with a communication pipe one 2013. The two ends of the communication pipe one 2013 are respectively communicated with two air pumps 2011. The bearing base 101 is also fixedly provided with an inflator 2015 for compensation according to the air pressure in the compensation air cylinder 2014. The adjusting assembly 203 comprises mounting plates 2031 symmetrically arranged at the two ends of each air pump 2011. Each mounting plate 2031 is fixedly provided with a connecting piece one 2032. Each connecting piece one 2032 is fixedly provided with a sliding block 2033. Each sliding block 2033 is slidably connected to the bearing base 101 through the sliding groove. The other end of each mounting plate 2031 is hingedly provided with a connecting piece two 2034. The other end of the connecting piece two 2034 is hingedly connected to the bottom end of the connecting seat 2021. The other side of the connecting seat 2021 is hingedly provided with a fixing piece 2035. The other end of the fixing piece 2035 is hingedly connected to the bearing base 101.

[0057] Wherein, in the damping assembly 202, when the motor 103 drive end speed is too large, the vibration force generated by the vertical pump body 102 can make the connecting column 2023 be subjected to extrusion force, which drives the connecting column 2023 to slide in the sliding groove 2036 of the cylinder body 2022. Between the sliding, the extrusion force of the connecting column 2023 first overcomes the elastic force of the spring one 2024 sleeved on the outer circumferential surface of the connecting column 2023. When the elastic force of the spring one 2024 is overcome, the extrusion force needs to overcome the elastic force of the spring two 2025 again. The damping assembly 202 is an assembled integral structure, so that the extrusion force of the connecting column 2023 can be reduced by the spring one 2024 and the spring two 2025 in the process of continuous shaking of the vertical pump body 102. Therefore, when the motor 103 drive end speed is too large, the vibration force generated by the vertical pump body 102 can be reduced by the damping assembly, effectively protecting the internal elements of the vertical pump body 102, preventing the internal elements from being damaged due to excessive vibration of the vertical pump body 102;

[0058] To this end, when the angle between the damping assembly 202 and the bearing base 101 needs to be reduced, the motor rotates faster, and the negative pressure transmission mechanism 300 can extract more gas from the compensation cylinder 2014. At this time, the compensation cylinder 2014 is in a pressure loss state, and can be extracted from the air pump 2011 through the communication pipe one 2013. When the air pump 2011 is extracted, the air pump 2011 will drive the two ends of the fixed connection plate 2031 to move closer to each other;

[0059] The fixing part 2035 can provide a support force to the damping assembly 202. When the two mounting plates 2031 move closer to each other, the two connecting parts one 2032 can be driven to move closer to each other. The connecting part one 2032 is fixedly installed with a sliding block 2033, which is T-shaped. The sliding groove 2036 is also T-shaped. Therefore, the two connecting parts one 2032 are limited in the sliding groove 2036 by sliding through the sliding block 2033. When the two connecting parts one 2032 move closer to each other, the connecting part two 2034, which is hingedly connected to the fixing part 2035 at one end, will increase the angle between the bearing base 101 and the damping assembly 202. Thus, the connecting part two 2034 increases the angle between the damping assembly 202 and the bearing base 101.

[0060] The inflation part 2015 is provided with a detection device for detecting the pressure condition in the compensation cylinder 2014. The inflation part is also provided with a control module. The control module, the detection device, and the inflation part 2015 are electrically connected. When the pressure value in the compensation cylinder 2014 is less than N, the detection module transmits a signal to the control module, and the control module controls the inflation part 2015 to inflate and pressurize the compensation cylinder 2014.

[0061] In summary, the device uses the negative pressure transmission mechanism 300 and the compensation adjustment mechanism 200 to effectively control the vibration of the vertical pump body 102. By using the double-layer damping assembly 202, when the vertical pump body 102 vibrates due to the excessive speed of the motor 103 driving end, the vibration force can be effectively absorbed and dispersed, thereby protecting the internal elements of the vertical pump body 102 from damage. This not only improves the working stability of the vertical pump body 102, but also prolongs the service life of the vertical pump body 102.

[0062] At the same time, the device can adjust the pressure in the compensation cylinder 2014 through the negative pressure transmission mechanism 300 according to the change of the motor driving end speed, and then control the extraction amount of the air pump 2011 in the compensation assembly 201. Thus, the angle between the damping assembly 202 and the bearing base 101 can be adjusted adaptively with the change of the working condition, so as to ensure that the vertical pump body 102 can maintain the best damping effect under different working conditions.

[0063] And, the device makes the slider 2033 slide in the T-shaped sliding groove 2036 by compensating the four-bar linkage mechanism in the compensation adjusting mechanism 200, so that the stability of the structure and the accuracy of the adjustment are realized. At the same time, the fixing part 2035 provides additional support force for the damping assembly 202, further enhancing the stability of the whole device.

[0064] Finally, the device also has a gas compensation mechanism. When the compensation gas cylinder 2014 is in a pressure loss state, the inflator 2015 can automatically compensate for the gas, ensuring the continuous and stable operation of the compensation adjusting mechanism, improving the reliability of the device, and avoiding the problem of adjustment failure caused by insufficient air pressure.

[0076] The acceleration assembly 303 further comprises the inner tooth sleeve ring 3032, the outer circumferential surface of the inner tooth sleeve ring 3032 is sleeved with the mounting rod 3014, the inner wall of the inner tooth sleeve ring 3032 is provided with an inner tooth ring, the mounting rod 3014 is fixedly arranged on the mounting frame 3011, the mounting rod 3014 is rotationally provided with the sun gear 3033, the sun gear 3033 is located at the inner axis of the inner tooth sleeve ring 3032 and is coaxially distributed with the inner tooth sleeve ring 3032, a plurality of planetary gears 3034 are evenly arranged between the inner wall of the inner tooth sleeve ring 3032 and the sun gear 3033, and the bottom end of the sun gear 3033 is fixedly provided with the air suction impeller 3035.

[0077] Both ends of the mounting rod 3012 and the mounting rod 3013 are connected to the inner wall of the mounting frame 3011.

[0078] When the rotation speed of the driving end of the motor 103 is too fast, the pulley 3021 rotates, and the locking piece 3024 is driven to rotate through the transmission seat 3022. Since the outer side of the locking piece 3024 is provided with locking teeth matched with the locking teeth of the inner wall of the sleeve ring 3023, when the rotation speed of the locking piece 3024 reaches a certain degree, the locking piece 3024 expands outward along the hinged part under the action of centrifugal force, and the part of the locking piece 3024 not hinged to the positioning column 3025 expands outward away from the hinged part under the action of centrifugal force. At this time, the locking teeth on the locking piece 3024 will engage with the locking teeth of the inner wall of the sleeve ring 3023, so as to lock the rotation of the pulley 3021 and transmit the rotation force to the sleeve ring 3023.

[0079] The permanent magnet 3027 at the bottom center of the collar 3023 is magnetically connected with the permanent magnet 3031 in the acceleration assembly 303, so that when the collar 3023 rotates, the permanent magnet 3031 also rotates. The rotation of the permanent magnet 3031 drives the rotation of the sun gear 3033 inside the inner toothed collar 3032, and the sun gear 3033 transmits the rotation force to the inner toothed collar 3032 through the planetary gear 3034, so that the inner toothed collar 3032 rotates at a faster speed; the bottom end of the sun gear 3033 is fixed with the air suction impeller 3035, so that when the sun gear 3033 rotates, the air suction impeller 3035 also rotates to generate negative pressure air, which is transmitted to the compensation air cylinder 2014 in the compensation adjusting mechanism 200 to extract the air pressure inside the compensation air cylinder 2014.

[0080] At the same time, the valve stop assembly 304 opens and closes according to the negative pressure generated by the acceleration assembly 303 to control the transmission of negative pressure air. When the negative pressure reaches a certain degree, the valve stop assembly 304 opens to allow the transmission of negative pressure air; when the negative pressure decreases, the valve stop assembly 304 closes to prevent the leakage of negative pressure air.

[0081] In summary, the negative pressure transmission mechanism 300 realizes the conversion of the rotation force of the driving end of the motor 103 into negative pressure air through the cooperative work of the centrifugal locking assembly 302, the acceleration assembly 303 and the valve stop assembly 304, and realizes the self-adaptive adjustment of the vibration of the vertical pump body 102 by adjusting the air pressure in the compensation adjusting mechanism 200.

[0082] The valve stop assembly 304 includes a sleeve 3041 fixedly arranged on the bearing base 101, the inner wall of the sleeve 3041 is sleeved outside the air suction impeller 3035, a gap is left between the inner wall of the sleeve 3041 and the air suction impeller 3035, a through groove is formed in the top of the sleeve 3041, the sleeve 3041 and one end of the compensation air cylinder 2014 are in communication with each other, and the inner wall of the sleeve 3041 is provided with a valve stop piece.

[0083] The valve stop piece includes a mounting cylinder 3042 fixedly arranged on the inner wall of the sleeve 3041, a limiting plate 3044 fixedly connected with the inner wall of the mounting cylinder 3042 is arranged at the opening of one end of the mounting cylinder 3042, limiting grooves are symmetrically formed in the limiting plate 3044, a hinge rod 3046 is slidably arranged on the limiting plate 3044 through the limiting grooves, the other two ends of the hinge rod 3046 are hingedly provided with fixing seats 3045, a valve plate 3043 is connected with each of the fixing seats 3045, the two valve plates 3043 are hingedly connected through a connecting shaft, the connecting shaft is rotatably connected with the inner wall of the mounting cylinder 3042, and springs four 3047 for assisting resetting are fixedly arranged between the two valve plates 3043.

[0084] The sleeve 3041 is fixed on the bearing base 101, and the inner wall of the sleeve 3041 is sleeved on the outer wall of the air suction impeller 3035, and a gap is left between the sleeve 3041 and the air suction impeller 3035 to ensure smooth flow of air or negative pressure air. A through slot is formed in the top of the sleeve 3041, which enables the inside of the sleeve to communicate with the outside environment or the compensation air cylinder 2014. At the same time, the sleeve 3041 and the compensation air cylinder 2014 are in communication with each other, so as to realize the transmission of negative pressure air between them. A limiting plate 3044 is arranged at the opening of the mounting cylinder 3042, which is used to fix and support the subsequent valve plate 3043 and other components. Limiting grooves are symmetrically formed in the limiting plate 3044, which provide sliding tracks for the hinged rods 3046. The two ends of the hinged rods 3046 are respectively hinged to the fixed seats 3045, and the fixed seats 3045 are connected to the valve plate 3043. The two valve plates 3043 are hinged through a connecting shaft, which enables them to swing at a certain angle relative to the inner wall of the mounting cylinder 3042. At the same time, a spring 3047 is fixed between the two valve plates 3043, which is used to assist the valve plate 3043 to return to the initial position after being subjected to external force;

[0085] Further, when the air suction impeller 3035 rotates to generate negative pressure air, the air will act on the valve plate 3043 inside the sleeve 3041. Since the valve plate 3043 is connected to the mounting cylinder 3042 through the hinged rods 3046 and the fixed seats 3045, it can swing under the action of negative pressure air. When the negative pressure air is large enough, it can overcome the elastic force of the spring 3047, so that the valve plate 3043 swings towards the through slot of the sleeve 3041, thereby opening the through slot and allowing the negative pressure air to enter the compensation air cylinder 2014 through the sleeve 3041. In this way, the negative pressure transmission mechanism 300 can adjust the air pressure inside the compensation air cylinder 2014 to realize adaptive adjustment of the vibration of the vertical pump body 102. When the negative pressure air decreases, the elastic force of the spring 3047 will push the valve plate 3043 to swing in the opposite direction, thereby closing the through slot and preventing the leakage of negative pressure air. This automatic adjustment mechanism ensures the stability and reliability of the negative pressure transmission mechanism 300;

[0086] In summary, the negative pressure transmission mechanism 300 converts the rotation force of the driving end of the motor 103, so that when the rotation speed of the driving end of the motor 103 is too fast, the centrifugal locking assembly 302 can respond quickly, lock the rotation of the pulley 3021, and transmit the rotation force to the collar one 3023. Subsequently, through the magnetic force transmission connection between the permanent magnet one 3027 and the permanent magnet two 3031, the acceleration assembly 303 is activated, and the cooperation of the sun gear 3033 and the planetary gear 3034 makes the air impeller 3035 rotate at a faster speed, thereby generating negative pressure wind; this negative pressure wind is transmitted to the compensation air cylinder 2014 in the compensation adjustment mechanism 200 through the sleeve 3041, for adjusting the air pressure inside, thereby realizing the adaptive adjustment of the vibration of the vertical pump body 102. In this process, the valve locking assembly 304 automatically opens and closes the through slot through the negative pressure generated by the acceleration assembly 303, thereby controlling the transmission of negative pressure wind, preventing the leakage of negative pressure wind, and ensuring the stability and reliability of the negative pressure transmission mechanism 300; therefore, the negative pressure transmission mechanism 300 can adapt to the needs under different working conditions, and the damage caused by the vibration of the vertical pump body 102 is alleviated, thereby effectively improving the working efficiency of the vertical pump and prolonging its service life.
