Description

Technical Field

[0001] The invention relates to the technical field of centrifugal pumps, in particular to an improved axial force self-balancing centrifugal chemical pump. Background Art

[0002] Chemical pumps are energy-saving pumps designed jointly by the whole country. They are widely used in industrial and urban water supply and drainage, and can also be used for irrigation and drainage of farmland and orchards to transport clean water or other liquids with physical and chemical properties similar to clean water. Chemical centrifugal pumps refer to centrifugal pumps used in the chemical industry. Compared with other types of pumps, chemical centrifugal pumps have the advantages of simple structure, not easy to wear, stable operation, low noise, uniform water output, convenient adjustment, and high efficiency. Therefore, chemical centrifugal pumps have been widely used.

[0003] When the centrifugal pump is running, the front of the impeller will directly contact the water flow and then be subjected to axial impact force. When the axial pressure difference between the front and back sides of the impeller reaches a certain value, the impeller will be deformed to a certain extent, and the bearing will also be damaged due to axial force overload, affecting the normal operation and service life of the structure.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 13 , a technical solution provided by the present invention:

[0037] An improved axial force self-balancing centrifugal chemical pump includes a bottom plate, a motor and a first housing 1 are fixedly mounted on the bottom plate, a rotating shaft 3 is rotatably mounted on the inner wall of the first housing 1 through a bearing 8, an impeller 5 is fixedly connected to one end of the rotating shaft 3, and the other end of the rotating shaft 3 is fixedly connected to the output end of the motor. A suction port is provided at one end of the first housing 1, and a discharge port is provided on the surface of the first housing 1. When the motor is running, the impeller 5 can be driven to rotate through the rotating shaft 3, thereby sucking the fluid into the first housing 1 from the suction port and discharging it outside the device through the discharge port.

[0038] In this embodiment, a cavity 12 is provided between the back of the impeller 5 and the first housing 1 to prevent the end face of the impeller 5 from contacting the inner wall of the first housing 1, thereby preventing the impeller 5 from being subjected to excessive axial force and generating excessive pressure between the impeller 5 and the first housing 1, thereby affecting the normal rotation of the impeller 5. The second housing 2 is fixedly connected to one end of the first housing 1, and a through hole 11 is provided on one end of the first housing 1, so that the air in the second housing 2 can enter the first housing 1. A balancing mechanism 4 is provided inside the second housing 2 for changing the gas pressure in the cavity 12, thereby providing a supporting force to the back of the impeller 5 through pressure for balancing the impact force of the fluid.

[0039] In this embodiment, a fixing frame 6 is fixedly connected to the inner wall of the first housing 1, a rotating ring 7 is fixedly connected to the back of the impeller 5, the surface of the rotating ring 7 is rotatably connected to the inner wall of the fixing frame 6, and there is a gap between the end of the rotating ring 7 away from the impeller 5 and the inner wall of the fixing frame 6, so as to avoid excessive pressure between the rotating ring 7 and the fixing frame 6 due to axial force. Through the cooperation of the fixing frame 6 and the rotating ring 7, the sealing between the first housing 1 and the impeller 5 can be improved to prevent leakage of gas in the cavity 12.

[0040] In this embodiment, a baffle 9 is fixedly connected to the first shell 1 , and the baffle 9 is used to shield one side of the bearing 8 to prevent the air pressure from directly impacting the internal structure of the bearing 8 and affecting the normal operation of the bearing 8 .

[0041] In this embodiment, the balancing mechanism 4 includes a fixed rod 44, one end of which is fixedly connected to one end of the first shell 1, and the other end of which is fixedly connected to the inner wall of the second shell 2. A sliding plate 41 is slidably connected to the fixed rod 44, and the outer circumference of the sliding plate 41 is in contact with the inner wall of the second shell 2, and the inner circumference of the sliding plate 41 is in contact with the surface of the rotating shaft 3, so that the sliding plate 41 is in a relatively sealed state with the second shell 2 and the rotating shaft 3, so that when the sliding plate 41 moves, the gas in the cavity 12 can be compressed. One end of the sliding plate 41 is elastically connected to the first shell 1 through a spring, so that it can be automatically reset. An adaptive device 42 and a temperature compensation device 43 are respectively provided on the sliding plate 41.

[0042] In this embodiment, the adaptive device 42 includes a fixed plate 421, which is fixedly connected to the inner wall of the second shell 2, and a support plate 422 is fixedly connected to the fixed plate 421. A rotating rod 423 is rotatably installed on the support plate 422, and a swing plate 424 is fixedly connected to the rotating rod 423. A sliding rod 425 is fixedly connected to one end of the swing plate 424, and a guide frame 426 is arranged on the outside of the sliding rod 425. Specifically, one side of the guide frame 426 is fixedly connected to the sliding plate 41, and an annular groove is opened inside the guide frame 426, and the surface of the sliding rod 425 is slidably connected to the inner wall of the annular groove. When the rotating rod 423 rotates clockwise, it can drive the swing plate 424 to swing clockwise, thereby causing the sliding rod 425 to make a circular motion around the rotating rod 423. At this time, since the guide frame 426 cannot make a circular motion with the sliding rod 425, during the circular motion of the sliding rod 425, the sliding plate 41 will be pushed to one side of the impeller 5 through the guide frame 426, thereby compressing the air between the sliding plate 41 and the impeller 5.

[0043] Furthermore, the adaptive device 42 also includes a transmission ring 428, which is sleeved on the outer surface of the rotating shaft 3. A plurality of annular teeth 429 are fixedly connected to the outer circumference of the transmission ring 428. The plurality of annular teeth 429 are equidistantly distributed along the axial direction of the rotating shaft 3. A gear 427 is meshed on the surface of the annular teeth 429. The gear 427 is fixedly connected to the rotating rod 423. When the annular teeth 429 move axially, their effect on the gear 427 is equivalent to a rack, thereby driving the gear 427 to rotate. An inner slide 4210 is fixedly connected to the inner circumference of the transmission ring 428. A slide groove for the inner slide 4210 to slide is provided on the inner wall of the rotating shaft 3. The surface of the inner slide 4210 is slidably connected to the inner wall of the slide groove. When the rotating shaft 3 rotates, the transmission ring 428 can be synchronously driven to rotate through the slide groove and the inner slide 4210. Since the annular tooth 429 is annular in shape, it will not cause motion interference with the gear 427 when rotating, and can always mesh with the gear 427 after rotating.

[0044] Furthermore, one end of the inner slide plate 4210 is fixedly connected to a transmission rod 4211, the surface of the transmission rod 4211 is slidably connected to the inner wall of the rotating shaft 3, and one end of the transmission rod 4211 is fixedly connected to a push block 4212. One end of the push block 4212 is elastically connected to the inner wall of the rotating shaft 3 through a spring, and the other end of the push block 4212 penetrates the rotating shaft 3 and the impeller 5 and is exposed to the fluid. When the fluid pressure increases, the push block 4212 can be pushed to the right. When the fluid pressure decreases, the push block 4212 will automatically reset under the elastic force of the spring, so that the adaptive device 42 can automatically operate according to the change of fluid pressure.

[0045] In this embodiment, the temperature compensation device 43 includes a temperature conducting cylinder 431, which is fixedly connected to the inner wall of the sliding plate 41. An opening is provided at one end of the temperature conducting cylinder 431 so that the fluid can enter the interior of the temperature conducting cylinder 431. A memory spring 432 is fixedly connected to the inner wall of the temperature conducting cylinder 431. An adjustment plate 433 is provided at one end of the memory spring 432. The outer circumference of the adjustment plate 433 is in contact with the inner wall of the temperature conducting cylinder 431. The memory spring 432 is made of a memory alloy, and its length can change with temperature. When the temperature increases to a certain value, the memory spring 432 will automatically contract and drive the adjustment plate 433 to move to the left, thereby increasing the space on the right side of the adjustment plate 433, which can accommodate more gas and achieve the purpose of balancing the external air pressure.

[0046] It is worth noting that one end of the memory spring 432 is fixedly connected to a driving plate 434, and one end of the driving plate 434 away from the memory spring 432 is elastically connected to the inner wall of the adjustment plate 433 through a spring. A transmission plate 435 is fixedly connected to the driving plate 434, and a folding groove 4351 is provided on the transmission plate 435. A control rod 437 is slidably connected to the inner wall of the folding groove 4351. When the folding groove 4351 moves left and right, the control rod 437 can be pushed downward through the inclined surface. One end of the control rod 437 penetrates the transmission plate 435 and is fixedly connected to a card plate 436. The surface of the card plate 436 is slidably connected to the inner wall of the temperature conducting cylinder 431. A plurality of card slots 4311 are provided on the inner wall of the temperature conducting cylinder 431, and the plurality of card slots 4311 are distributed in a straight line with equal distances along the length direction of the temperature conducting cylinder 431. One end of the card plate 436 penetrates the adjustment plate 433 and is inserted into one of the card slots 4311, thereby limiting the relative movement between the adjustment plate 433 and the temperature conducting cylinder 431, so that when the air pressure on the right side of the adjustment plate 433 increases, the adjustment plate 433 will not be pushed in the opposite direction, and when the length of the memory spring 432 changes, the driving plate 434 will be driven horizontally first, and the driving plate 434 drives the control rod 437 to shrink inside the adjustment plate 433 through the transmission plate 435, thereby driving the card plate 436 to disengage from the card slot 4311. When the card plate 436 is completely out of the card slot 4311, the driving plate 434 can drive the control rod 437 to move horizontally through the transmission plate 435, so that the movement of the driving plate 434 is only affected by the temperature change.

[0047] In addition, an extension plate 438 is fixedly connected to the surface of the card plate 436, and the extension plate 438 is slidably connected to the inner wall of the adjustment plate 433. The extension plate 438 is elastically connected to the adjustment plate 433 through a spring, so that the card plate 436 can automatically reset and enter the card slot 4311.

[0048] Working principle: When the motor starts, the impeller 5 is driven to rotate through the rotating shaft 3, so that the centrifugal pump starts to operate, and then the fluid is sucked from one end of the first housing 1, and the fluid is discharged from the outlet at the top of the first housing 1 through the rotation of the impeller 5. When the fluid enters the first housing 1 and contacts the impeller 5, it will impact the end of the rotating shaft 3. When the impact force reaches a certain value, it will push the push block 4212 into the rotating shaft 3.

[0049] When the push block 4212 moves, it will synchronously drive the transmission rod 4211 to move, and the transmission rod 4211 drives the transmission ring 428 to move through the inner slide plate 4210, thereby causing the annular gear 429 on the transmission ring 428 to move horizontally. The annular gear 429 drives the gear 427 to rotate clockwise through meshing, and the gear 427 drives the swing plate 424 to swing clockwise through the rotating rod 423, thereby causing the slide bar 425 to make a circular motion around the rotating rod 423. At this time, since the guide frame 426 cannot make a circular motion with the slide bar 425, during the circular motion of the slide bar 425, the guide frame 426 will push the slide plate 41 to one side of the impeller 5, thereby compressing the air between the slide plate 41 and the impeller 5. After the air is compressed, the air pressure increases, thereby providing support force for the back of the impeller 5. The support force is affected by the front impact force of the impeller 5. When the impact force is greater, the sliding amplitude of the sliding plate 41 is greater, the volume of the cavity 12 between the sliding plate 41 and the impeller 5 is smaller, the air pressure is greater, and the support force provided to the impeller 5 is greater.

[0050] As the operation time of the centrifugal pump increases, the temperature of the pump body will increase, so that the gas activity between the sliding plate 41 and the impeller 5 increases, and the air pressure further increases. At this time, the temperature compensation device 43 automatically operates to eliminate the influence of temperature on the air pressure. The specific method is: the temperature of the temperature conducting cylinder 431 increases with the increase of the temperature of the centrifugal pump. When the temperature reaches a certain value, the memory spring 432 will automatically shrink and drive the driving plate 434 to move to the left. The driving plate 434 simultaneously drives the transmission plate 435 on it to move. The transmission plate 435 drives the control rod 437 to shrink inside the adjustment plate 433 through the folding groove 4351, and then drives the card plate 436 to disengage from the card slot 4311. When the card plate 436 is completely out of the card slot 4311, the driving plate 434 can drive the control rod 437 to move horizontally through the transmission plate 435. The control rod 437 drives the adjustment plate 433 to move to the left through the card plate 436 and the extension plate 438, so that the space on the right side of the adjustment plate 433 is increased, and the gas that can be accommodated inside the space increases. At this time, the gas in the cavity 12 enters the interior through the opening at one end of the temperature conducting tube 431 , so that the air pressure in the cavity 12 is reduced, thereby eliminating the influence of temperature on the air pressure.
