Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a vertical pump with a self-compensating thrust balancing device. Background Art

[0002] A pump is a machine that transports fluid or pressurizes fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids. Pumps can usually be divided into three categories according to their working principles: positive displacement pumps, dynamic pumps and other types of pumps. In addition to being classified by working principles, pumps can also be classified and named by other methods. For example, they can be divided into electric pumps and water turbine pumps according to the driving method; they can be divided into single-stage pumps and multi-stage pumps according to the structure; they can be divided into boiler feed pumps and metering pumps according to their use; they can be divided into water pumps, oil pumps and mud pumps according to the nature of the transported liquid; they can be divided into linear pumps and traditional pumps according to whether there is a shaft structure. Water pumps can only transport logistics with fluid as the medium, and cannot transport solids. However, in actual use, the pump will vibrate when working, and long-term vibration will reduce the service life of the pump and motor.

[0003] The Chinese patent with the authorization announcement number CN210829762U discloses a vibration-proof vertical pump, including a housing, a base is provided at the bottom of the housing, bolts are provided inside the base, mounting holes are provided inside both sides of the base, both mounting holes are designed as one-piece with the bolts, and a shock-absorbing mechanism is provided inside the mounting hole; the shock-absorbing mechanism includes a clamp, a moving cavity is provided inside the base at a position corresponding to the clamp, the clamp is slidably connected to the inside of the moving cavity, a plurality of first springs are provided at one end of the clamp away from the housing, two rubber layers are provided at the bottom of the housing, and a plurality of cavities are provided inside the rubber layer. The technical solution is to press the housing against the clamp, and when the housing vibrates, the clamp squeezes the moving cavity, and the clamp can reduce vibration from the corresponding vibration position, and a cavity is provided inside the rubber layer, and a second spring is provided inside the cavity to reduce vibration of the housing.

[0004] However, this technical solution still has some problems: the device only performs maximum shock absorption on the vertical pump through the initial preset process, so that the vertical pump is always in a low position, and this method cannot perform self-compensation balance according to the vibration conditions of the vertical pump during the operation of the vertical pump.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0045] Example 1

[0046] Reference Figure 1-Figure 4 , which is the first embodiment of the present invention, provides a vertical pump with a self-compensating thrust balancing device.

[0047] Specifically, they include:

[0048] A bearing mechanism 100, wherein 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 adjustment mechanism 200 is used to change the damping angle according to the vibration amplitude of the vertical pump body 102 and damp the vertical pump body 102;

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

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

[0052] The compensation adjustment mechanism 200 includes a shock absorbing component 202 and a compensation adjustment component;

[0053] The shock absorbing assembly 202 is used to cushion the vibration force generated by the motor 103 driving the vertical pump body 102 through a double-layer shock absorbing method, and the compensation adjustment assembly is used to adjust the angle between two laterally adjacent shock absorbing assemblies 202 according to the rotation speed of the driving end of the motor 103, and adjust the longitudinal distance between the vertical pump body 102 and the supporting base 101.

[0054] The shock absorbing assembly 202 includes a connecting seat 2021, on which a cylinder 2022 is fixedly provided, a slide groove 2036 is provided in the cylinder 2022, a through hole is provided in the cylinder 2022, a connecting column 2023 is slidably provided on the cylinder 2022 through the through hole and the slide groove 2036, a spring 2025 for compensating for the reset force of the connecting column 2023 is provided in the slide groove 2036 of the cylinder 2022, two ends of the spring 2025 are respectively connected to the connecting column 2023 and the connecting seat 2021, the connecting seat 2021 and the connecting column 2023 are both provided with shoulders, a spring 1 2024 is provided between the connecting seat 2021 and the shoulders of the connecting column 2023, the spring 1 2024 is sleeved on the outer circumferential surface of the connecting column 2023, and the top of each of the connecting columns 2023 is hinged to the vertical pump body 102.

[0055] Among them, in the shock absorbing assembly 202, when the speed of the driving end of the motor 103 is too large, the vibration force generated by the vertical pump body 102 will cause the connecting column 2023 to be subjected to an extrusion pressure, which will drive the connecting column 2023 to slide in the slide groove 2036 of the cylinder 2022. During the sliding, the extrusion force of the connecting column 2023 first overcomes the elastic force of the spring 1 2024 sleeved on the outer peripheral surface of the connecting column 2023. After overcoming the elastic force of the spring 1 2024, the extrusion force needs to overcome the elastic force of the spring 2 2025 again. The shock absorbing assembly 202 is an assembled integrated structure, so that the extrusion force on the connecting column 2023 can be reduced by the spring 1 2024 and the spring 2 2025 during the continuous shaking of the vertical pump body 102. Therefore, when the rotation speed of the driving end of the motor 103 is too high, the vibration force generated by the vertical pump body 102 can be reduced by the shock absorbing component, effectively protecting the internal components of the vertical pump body 102 and preventing the internal components from being damaged due to excessive vibration of the vertical pump body 102;

[0056] The bearing base 101 is symmetrically provided with slideways, the compensating and adjusting components include a compensating component 201 and an adjusting component 203, the compensating component 201 includes a mounting seat 2012 symmetrically provided on the bearing base 101 and corresponding to the slide groove 2036, an air pump 2011 is fixedly provided on each mounting seat 2012, the bearing base 101 is also fixedly provided with a compensating air cylinder 2014, the compensating air cylinder 2014 is connected with a connecting pipe 2013, the two ends of the connecting pipe 2013 are respectively connected with the two air pumps 2011, and the bearing base 101 is also fixedly provided with a Inflatable member 2015; the adjustment assembly 203 includes mounting plates 2031 symmetrically arranged at both ends of each air pump 2011, each mounting plate 2031 is fixedly provided with a connecting member 1 2032, each connecting member 1 2032 is fixedly provided with a slider 2033, each slider 2033 is slidably connected to the bearing base 101 through a slide, the other end of the mounting plate 2031 is hingedly provided with a connecting member 2034, the other end of the connecting member 2034 is hinged to the bottom end of the connecting seat 2021, the other side of the connecting seat 2021 is hingedly provided with a fixing member 2035, the other end of the fixing member 2035 is hinged to the bearing base 101;

[0057] When the vertical pump body 102 vibrates too much, the shock absorbing assembly 202 needs to reduce the angle between the shock absorbing assembly 202 and the bearing base 101, thereby reducing the distance between the vertical pump body 102 and the bearing base 101, that is, reducing the height of the vertical pump body 102, so as to enhance the shock absorbing effect of the shock absorbing assembly;

[0058] Therefore, when it is necessary to reduce the angle between the shock absorbing assembly 202 and the bearing base 101, the faster the motor speed is, the more gas in the compensation gas cylinder 2014 is pumped out through the negative pressure transmission mechanism 300; at this time, the compensation gas cylinder 2014 is in a depressurized state, and gas can be pumped out from the air pump 2011 through the connecting pipe 1 2013; when the air pump 2011 is pumped out, the air pump 2011 will drive the mounting plates 2031 fixedly connected at both ends to approach each other;

[0059] The fixing member 2035 can provide a supporting force for the shock absorbing assembly 202. At the same time, when the two mounting plates 2031 are close to each other, the two connecting members 1 2032 can be driven to be close to each other. The connecting member 1 2032 is fixedly mounted with a slider 2033. The slider 2033 is T-shaped, and the slide groove 2036 is a T-shaped slide groove 2036. Therefore, the two connecting members 1 2032 slide in the slide groove 2036 through the slider 2033 and are limited by the slide groove 2036. When the two connecting members 1 2032 are close to each other, the connecting member 2 2034 whose one end is hinged to the fixing member 2035 will increase the angle between it and the bearing base 101, so that the angle between the shock absorbing assembly 202 and the bearing base 101 is reduced during the process of the connecting member 2 2034 increasing the angle.

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

[0061] In summary, the device realizes effective control of the vibration of the vertical pump body 102 through the negative pressure transmission mechanism 300 and the compensation adjustment mechanism 200; by using the shock absorbing component 202 with a double-layer shock absorbing structure, when the vertical pump body 102 vibrates due to the excessive rotation speed of the driving end of the motor 103, the vibration force can be effectively absorbed and dispersed, thereby protecting the internal components of the vertical pump body 102 from damage, which 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 air pressure in the compensation air cylinder 2014 according to the change of the rotation speed of the motor drive end through the negative pressure transmission mechanism 300, thereby controlling the air pumping amount of the air pump 2011 in the compensation component 201; thereby, the angle between the shock absorbing component 202 and the bearing base 101 can be adaptively adjusted as the working conditions change, thereby ensuring that the vertical pump body 102 can maintain the best shock absorbing effect under different working conditions;

[0063] Moreover, through the four-bar mechanism in the compensation adjustment mechanism 200, the device enables the slider 2033 to slide within the T-shaped chute 2036, achieving structural stability and precise adjustment. Meanwhile, the fixing member 2035 provides additional support for the shock-absorbing assembly 202, further enhancing the stability of the entire device.

[0064] Finally, the device also has a gas compensation mechanism. When the compensation air cylinder 2014 is in a depressurized state, the inflating member 2015 can automatically perform gas compensation to ensure the continuous and stable operation of the compensation adjustment mechanism, not only improving the reliability of the device but also avoiding the problem of adjustment failure caused by insufficient air pressure.

[0075] The acceleration assembly 303 includes a second permanent magnet 3031, the outer circumference of which is sleeved with a second mounting rod 3013, the second permanent magnet 3031 is rotatably connected to the second mounting rod 3013, and the second permanent magnet 3031 is coaxially distributed with the first permanent magnet 3027 and connected by magnetic transmission;

[0078] When the speed of the driving end of the motor 103 is too fast, the pulley 3021 rotates accordingly, and drives the locking member 3024 to rotate through the transmission seat 3022. Since the outer side of the locking member 3024 is provided with a locking tooth that cooperates with the locking tooth on the inner wall of the collar 1 3023 to lock, when the speed of the locking member 3024 reaches a certain level, the locking member 3024 expands outward along the hinge under the action of centrifugal force, and the part where the locking member 3024 is not hinged with the positioning column 3025 drives the locking member 3024 to expand outward away from the hinge through the centrifugal force; at this time, the locking tooth on the locking member 3024 will mesh with the locking tooth on the inner wall of the collar 1 3023, thereby locking the rotation of the pulley 3021 and transmitting the rotational force to the collar 1 3023;

[0079] The permanent magnet 1 3027 at the bottom center of the collar 1 3023 is connected to the permanent magnet 2 3031 in the acceleration assembly 303 by magnetic transmission, so when the collar 1 3023 rotates, the permanent magnet 2 3031 will also rotate. The rotation of the permanent magnet 2 3031 drives the sun gear 3033 inside the inner gear collar 3032 to rotate, and the sun gear 3033 transmits the rotational force to the inner gear collar 3032 through the transmission action of the planetary gear 3034, so that the inner gear collar 3032 rotates at a faster speed; the bottom end of the sun gear 3033 is fixed with an exhaust impeller 3035, so when the sun gear 3033 rotates, the exhaust impeller 3035 will also rotate, generating negative pressure wind force, which is transmitted to the compensation air cylinder 2014 in the compensation adjustment mechanism 200 by forming negative pressure air in the sleeve 3041, and is used to extract the air pressure inside it.

[0080] At the same time, the valve stop assembly 304 will open and close according to the magnitude of the negative pressure generated by the acceleration assembly 303 to control the transmission of the negative pressure wind force. When the negative pressure reaches a certain level, the valve stop assembly 304 will open to allow the negative pressure wind force to be transmitted; when the negative pressure decreases, the valve stop assembly 304 will close to prevent the leakage of the negative pressure wind force.

[0081] In summary, the negative pressure transmission mechanism 300 realizes the function of converting the rotational force of the driving end of the motor 103 into negative pressure wind force through the coordinated work of the centrifugal locking component 302, the acceleration component 303 and the valve stop component 304, and realizes the adaptive adjustment of the vibration of the vertical pump body 102 by adjusting the air pressure in the compensation adjustment mechanism 200.

[0082] The valve stop assembly 304 includes a sleeve 3041 fixed on the supporting base 101, the inner wall of the sleeve 3041 is sleeved outside the exhaust impeller 3035, a gap is left between the inner wall of the sleeve 3041 and the exhaust impeller 3035, a through groove is opened on the top of the sleeve 3041, the sleeve 3041 is connected with one end of the compensation air cylinder 2014, and a valve stop is provided on the inner wall of the sleeve 3041.

[0083] The valve stopper comprises a mounting tube 3042 fixedly mounted on the inner wall of the sleeve 3041, a limiting plate 3044 fixedly connected to the inner wall of the mounting tube 3042 is disposed at an opening at one end of the mounting tube 3042, limiting grooves are symmetrically arranged on the limiting plate 3044, a hinge rod 3046 is slidably disposed on the limiting plate 3044 through the limiting groove, and the other two ends of the hinge rod 3046 are hingedly provided with a fixing seat 3045, each of the fixing seats 3045 is connected to a valve plate 3043, the two valve plates 3043 are hingedly connected by a connecting shaft, the connecting shaft is rotatably connected to the inner wall of the mounting tube 3042, and a spring 3047 for auxiliary resetting is also fixedly disposed between the two valve plates 3043;

[0084] Among them, the sleeve 3041 is fixedly arranged on the bearing base 101, and its inner wall is sleeved outside the exhaust impeller 3035, and a gap is left between the two to ensure the smooth flow of air or negative pressure wind. A through groove is provided on the top of the sleeve 3041, so that the inside of the sleeve can be connected with the external environment or the compensation air cylinder 2014. At the same time, the sleeve 3041 and one end of the compensation air cylinder 2014 are connected to each other, thereby realizing the transmission of negative pressure wind between the two; at the opening of one end of the installation cylinder 3042, a limit plate 3044 is provided, which is used to fix and support subsequent valve plates 3043 and other components. The limit plate 3044 is symmetrically provided with limit grooves, which provide sliding tracks for the hinged rod 3046. The two ends of the hinged rod 3046 are respectively hinged on the fixed seat 3045, and the fixed seat 3045 is connected to the valve plate 3043. The two valve plates 3043 are hinged via 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 plates 3043 to return to their initial positions after being acted upon by external forces;

[0085] Furthermore, when the impeller 3035 rotates to generate negative pressure wind force, this wind force 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 hinge rod 3046 and the fixing seat 3045, they can swing under the action of the negative pressure wind force; when the negative pressure wind force is large enough, it will overcome the elastic force of the spring four 3047, so that the valve plate 3043 swings in the direction of the through slot of the sleeve 3041, thereby opening the through slot and allowing the negative pressure wind force to enter the compensation air cylinder 2014 through the sleeve 3041. In this way, the negative pressure transmission mechanism 300 can realize adaptive adjustment of the vibration of the vertical pump body 102 by adjusting the air pressure inside the compensation air cylinder 2014; when the negative pressure wind force decreases, the elastic force of the spring four 3047 will push the valve plate 3043 to swing in the opposite direction, thereby closing the through slot and preventing the leakage of the negative pressure wind force. 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 transforms the rotational force of the driving end of the motor 103 so that when the driving end of the motor 103 rotates too fast, the centrifugal locking assembly 302 can respond quickly, lock the rotation of the pulley 3021, and transmit the rotational force to the collar 1 3023. Subsequently, through the magnetic transmission connection between the permanent magnet 1 3027 and the permanent magnet 2 3031, the acceleration assembly 303 is activated, and the coordinated work of the sun gear 3033 and the planetary gear 3034 causes the exhaust impeller 3035 to rotate at a faster speed, thereby generating negative pressure wind force; this negative pressure wind force is transmitted to the compensation air cylinder 2014 in the compensation adjustment mechanism 200 through the sleeve 3041, which is used to adjust the air pressure inside it, thereby realizing adaptive adjustment of the vibration of the vertical pump body 102. During this process, the valve stop assembly 304 automatically opens and closes the through slot by the negative pressure generated by the acceleration assembly 303, thereby controlling the transmission of the negative pressure wind force, preventing the leakage of the negative pressure wind force, 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 can be alleviated, thereby effectively improving the working efficiency of the vertical pump and extending its service life.
