Description

Technical Field

[0001] The invention relates to the technical field of asynchronous motor rotors, and in particular to an asynchronous motor rotor outer surface pickling device and a pickling process. Background Art

[0002] The asynchronous motor consists of two major parts: the stator and the rotor. During the long-term use of the rotor, in order to avoid abnormalities in the operation of the generator, the outer surface of the rotor must be cleaned when the generator is shut down for regular maintenance to prevent the performance of the motor from deteriorating due to reasons such as rust on the rotor surface.

[0003] At present, when cleaning the rotor of an asynchronous motor, pickling is usually used to clean the rust and other dirt on the rotor surface. The main purpose of pickling the outer surface of the rotor is to reduce the stray loss of the motor and improve the efficiency of the motor. The pickling process of the rotor outer surface can significantly reduce the stray loss of the motor and improve the efficiency of the motor by removing impurities and oxide layers on the rotor surface. Specifically, this treatment process includes the following steps: Surface cleaning: Pickling can clean the bearing surface using chemical cleaning methods to remove surface oxide scale and burrs, which is crucial to reducing stray losses in electric motors and improving efficiency.

[0004] ‌Reduce stray losses‌: Pickling treatment can effectively reduce the stray losses of the motor. Under the best treatment effect, the stray losses can be reduced to 1 / 5 of the original value. For low-voltage small and medium-sized motors, the efficiency can be increased by 0.5% to 1.5%.

[0005] At present, when pickling a rotor, both ends of the rotor are usually clamped, and then a rotating mechanism is used to drive the rotor to rotate.

The two brushes 407 are respectively provided with a plug 408 that can be inserted into the corresponding groove 401. Sliding blocks 501 are slidably provided on both sides of the workbench 5, and a motor 502 is fixedly provided on each sliding block 501. A through slot 503 is provided on each fixing member 305, and a rotating rod 504 inserted into the corresponding through slot 503 is fixedly provided at the output end of each motor 502.The rotating rod 504 is slidably connected with the through groove 503, a blocking member 6 is slidably provided in the main body 1, a sliding column 601 is fixedly provided at the lower end of the blocking member 6, the sliding column 601 is slidably connected with the main body 1, a second elastic member 602 located between the lower end of the blocking member 6 and the main body 1 is sleeved on the sliding column 601, a clearance groove 603 is provided on the workbench 5, the blocking member 6 can be inserted into the clearance groove 603, a plurality of travel switches 7 are respectively provided on both sides of the workbench 5, a controller 8 is provided on the main body 1, and each travel switch 7 Each of the travel switch 7 and the motor 502 is electrically connected to the controller 8, the solenoid valve 204 is electrically connected to the controller 8, the automatic telescopic member 307 is electrically connected to the controller 8, a discharge port 101 is provided on one side of the main body 1, a discharge port 102 is provided on the other side of the main body 1, a liquid collecting hopper 103 is provided in the main body 1, a filter 104 is provided in the collecting hopper 103, and one side of the collecting hopper 103 is connected to the inside of the acid tank 201 through a drain pipe 105.

[0037] During specific use, the initial state is set so that the guide member 302 is located at the extreme position of the guide groove 301 close to the discharge port 101, and the rotor of the motor is placed on the workbench 5 through the discharge port 101. When the rotor falls, the rotor contacts the blocking member 6, so that the rotor stops at an appropriate position, and then the two motors 502 are started, so that the motor 502 drives the fixing member 305 to rotate through the rotating rod 504 and the through groove 503, and the fixing member 305 drives the automatic telescopic member 307 and the clamping member 306 to rotate through the rotating member 304. Under the action of the guide groove 302 and the guide member 301, the fixing member 305 moves toward the direction of the discharge port 102 and moves inward at the same time, so that the two ends of the rotor are respectively inserted between the corresponding fixing members 305 and the clamping members 306.

[0038] Then, one of the fixing parts 305 touches the corresponding travel switch 7, and the travel switch 7 sends a signal to the controller 8, so that the controller 8 controls the motor 502 corresponding to the fixing part 305 to turn off, and the motor 502 on the other side remains on. At the same time, the automatic telescopic part 307 on the other side opens and pushes the corresponding clamping part 306 to move, clamping the corresponding end of the rotor. At the same time, the solenoid valve 204 opens, and the acid passes through the connecting pipe 203 and the solenoid valve 204 nozzle 202, so that the nozzle 202 sprays the rotor.

[0039] During the above process, the fixed column 403 is continuously inserted into the groove 401 under the action of the first elastic member 405, the sliding rod 404 and the movable plate 402, so that the clamping assembly 3 and the corresponding motor 502 and the sliding block 501 move as a whole. After one of the motors 502 is turned off, the groove 401 corresponding to the turned-on motor 502 continues to cooperate with the corresponding fixed column 403, and by driving the fixed member 305 and the rotating member 304 to rotate, the rotating member 304 drives the rotating ring 411 to rotate, so that the groove 401 on this side cooperates with the fixed column 403 on the corresponding side, pushing the rotor to move in the direction of the discharge port 102, and at the same time, the blocking member 6 moves downward and moves out of the give way groove 603, the second elastic member 602 is compressed, the sliding column 601 moves downward, and at the same time, the rotating ring 411 drives the rotor to rotate through the rotating member 304, which is beneficial for the nozzle 202 to spray the rotor in all directions.

[0040] At the same time, the rotor drives the corresponding clamping assembly 3 as a whole and the motor 502 to move through the fixing piece 305 on the other side. The moving piece 303 on the side corresponding to the closed motor 502 begins to continuously move along the axial direction of the motor 502 under the action of the guide groove 301 and the guide piece 302, and moves toward the discharge port 102 following the opened motor 502. At the same time, since the clamping piece 306 on the closed side does not clamp the rotor, the acid liquid of the nozzle 202 sprays the non-clamped side of the rotor through the liquid inlet pipe 310, the connecting pipe 309 and the drainage groove 308 to prevent the clamped position of the rotor from being pickled, resulting in failure to achieve the expected effect of pickling. Since the rotor rotates, and the fixing piece 305 corresponding to the side of the rotor that is not clamped does not rotate and moves left and right along the guide groove 301, the fixing piece 305 can rub the side of the rotor while the rotor rotates, which is convenient for removing dirt.

[0041] When the moving part 303 corresponding to the turned-on motor 502 touches the corresponding travel switch 7, under the control of the controller 8, the motor 502 on this side is turned off, and the motor 502 on the other side is turned on. At the same time, the controller 8 controls the automatic telescopic part 307 on this side to shrink, and the clamping part 306 on the side of the turned-off motor 502 moves upward under the action of the automatic telescopic part 307. It is set that each time the moving part 303 touches the travel switch 7, the rotating part 304 rotates a full circle. The number of fixed columns 403 can meet the above requirements, and the rotor is no longer clamped. Since the drainage groove 308 on the clamping part 306 is no longer clamped by the rotor Block, and start spraying acid on one side of the rotor that is initially clamped. At the same time, when the fixing part 305 moves along the axial direction of the motor 502 under the action of the guide groove 301, the guide part 302 and the movable part 303, it can also play a scraping role on the clamped side of the rotor, achieving a better cleaning effect. At this time, the clamping part 306 on the other side clamps the rotor, and the drainage groove 308 is covered, and the acid is no longer sprayed on the rotor. At the same time, the clamping part 306 on this side drives the rotor and the clamping assembly 3 on the other side to move as a whole, and the fixed column 403 on this side begins to cooperate with the groove 401, so that the rotor always moves in the direction of the discharge port 102.

[0042] The above-mentioned clamping process and loosening process are that one side is clamped and the other side is in a relaxed state, so that the drain groove 308 on the relaxed side sprays the rotor, and at the same time, when the fixing part 305 moves left and right, the sprayed side is scraped and brushed to remove dirt. When the rotor moves to the side of the guide groove 301 close to the discharge port 102, the movable part 303 touches the travel switch 7, so that the two clamping parts 306 no longer clamp the rotor. Under the action of the guide groove 301, the guide part 302 and the movable part 303, the two clamping components 3 begin to move away from the rotor and push the rotor to roll toward the discharge port 102. When the two sides of the rotor are no longer in contact with the clamping components 3, the rotor falls into the discharge port 102. At the same time, the workbench 5 can be set to an inclined state so that the liquid after spraying is discharged into the liquid collecting bucket 103. At the same time, the blocking part 6 and the give way groove 603 and the main body 1 can ensure the sealing during sliding to prevent corrosion.

[0043] After the moving parts 303 move to the limit position close to the discharge port 102, one of the moving parts 303 touches the travel switch 7, causing the controller 8 to close the solenoid valve 204, and the acid liquid no longer flows out. Then, according to the sequence of opening and closing of the two motors 502, the clamping assembly 3 and the like move toward the discharge port 101. When the acid liquid needs to be added, the controller 8 closes the solenoid valve 204, and the acid liquid stops flowing out. Figure 3 It can be seen that a baffle is slidably connected to the main body 1. The acid liquid box 201 is taken out and acid liquid is added thereto. The acid liquid box 201 is provided with an opening for adding acid liquid, which is not shown in the figure. The pickling can be continued.

[0044] In the above process, the circulation process of the acid liquid is as follows: the acid liquid is extracted through the suction pump 206 and the suction pipe 207, and then discharged into the nozzle 202 through the connecting pipe 203 and the solenoid valve 204, and discharged through the nozzle 202 and one of the drainage grooves 308 at the same time. The acid liquid after pickling is discharged into the collecting bucket 103 through the workbench 5, and after being filtered by the filter element 104, the filtered acid liquid is discharged into the acid liquid tank 201 through the drainage pipe 105, so that the acid liquid is continuously recycled to prevent the waste of the acid liquid. At the same time, the impurities in the acid liquid can be filtered through the filter element 104, so that the filtered acid liquid can be smoothly discharged into the acid liquid tank 201.

[0045] The rotor is clamped by the clamping assembly 3, and the fixing member 305 is driven to rotate by the motor 502, so that the clamping member 306 clamps one side of the rotor while the clamping member 306 on the other side can spray the unclamped side of the rotor, thereby realizing alternate spraying and alternate clamping of the clamped parts on both sides of the rotor, which can not only make the rotor rotate but also spray the clamped parts. At the same time, when one side of the rotor is not clamped, the fixing member 305 and the clamping member 306 can move the fixing member 305 left and right to scrape the rotor, and when the clamping member 306 can move left and right, the acid liquid sprays one side, thereby achieving a better cleaning effect.

[0046] Embodiment 2 While the clamping position of the rotor is being pickled, the outer surface of the rotor cannot be scraped and brushed synchronously, resulting in the inability to perform pickling and scraping synchronously, affecting the cleaning efficiency of the rotor. At the same time, the steps of pickling the rotor are increased, and the cleaning efficiency of the rotor cannot be effectively improved.

[0047] In order to solve the above technical problems, based on the above embodiments, please refer to Figures 1 to 11 The technical solution adopted includes two scraping brush assemblies 4, each of which includes a rotating ring 411 fixedly arranged on the outer side of the corresponding rotating member 304, each rotating ring 411 is provided with a plurality of grooves 401, movable plates 402 are slidably arranged on both sides of the workbench 5, each movable plate 402 is fixedly provided with a plurality of fixed columns 403 that can be inserted into the corresponding grooves 401, and sliding rods 404 are fixedly arranged at the opposite ends of the two movable plates 402, and each sliding rod 404 is sleeved with a first elastic member 405 located between the opposite ends of the two movable plates 402 and the workbench 5, and connecting members 406 are fixedly arranged on both sides of the nozzle 202, and two brushes 407 are slidably connected between the two connecting members 406, and an elastic reset member 410 is provided between the brush 407 and the connecting member 406, and the two brushes 407 are respectively provided with plug columns 408 that can be inserted into the corresponding grooves 401.

[0048] During the process of the rotor rotating and moving toward the discharge port 102, the nozzle 202 drives the two brushes 407 to move through the connecting piece 406, and the clamping piece 306 and the rotating ring 411 both rotate, so that the rotating ring 411 can drive the brushes 407 to move left and right through the corresponding grooves 401 and the plugs 408, and at the same time, it is continuously reset under the action of the elastic reset piece 410, so as to achieve pickling and scraping of the rotor surface at the same time, achieving a better cleaning effect.

[0049] While the clamping assembly 3 and the like move toward the discharge port 101, the nozzle 202 drives the two brushes 407 to move toward the initial position through the connecting piece 406, thereby resetting the device.

[0050] By providing the groove 401, the plug 408 and the brush 407, the brush 407 can be moved left and right, so that the outer surface of the rotor can be scraped while the acid is sprayed on the rotor, which is beneficial for faster removal of dirt on the rotor surface. At the same time, the brush 407 can make the acid more evenly distributed on the outer surface of the rotor, promote the contact between the acid and the dirt on the rotor surface, thereby achieving a better cleaning effect.

[0051] Embodiment 3 On the basis of the above embodiment, this embodiment further provides a pickling process for the outer surface of the asynchronous motor rotor, including the following specific steps: S1. The rotor of the motor is placed on the workbench 5 through the discharge port 101, the blocking member 6 positions the rotor, the motor 502 is started, and then the clamping assembly 3 clamps the rotor; S2. The motor 502 drives the fixed member 305 to rotate, so that the fixed member 305 drives the rotating member 304 to rotate, and the rotating member 304 drives the clamping member 306 to rotate, so that the rotor moves and rotates on the workbench 5; S3. The solenoid valve 204 is opened, so that the nozzle 202 sprays the rotor, and at the same time, the clamping member 306 sprays the unclamped side of the rotor, and at the same time, the fixing member 305 rubs the surface of the rotor to achieve a better cleaning effect; S4. While the rotor is rotating, the surface of the rotor is sprayed with acid, and the plug 408 cooperates with the groove 401 to make the brush 407 scrape the outer surface of the rotor to achieve rapid cleaning of the rotor surface.
