Description

Technical Field

[0001] This invention relates to the field of lubricating oil testing, and more particularly to a viscosity testing device for lubricating oil production. Background Technology

[0002] Lubricating oil is one of the essential key fluids in mechanical equipment and engines, playing a role in reducing friction, cooling, cleaning, sealing, and preventing corrosion. The viscosity of lubricating oil is an important indicator for measuring its fluidity and lubrication performance. Changes in viscosity directly affect the working performance of lubricating oil and its protective effect on mechanical parts.

[0003] After the lubricating oil is produced, its viscosity is usually tested to ensure that it meets the standard requirements. In actual testing, one of the commonly used testing methods is to measure the viscosity of the lubricating oil using a rotational viscometer. The rotational viscometer calculates the viscosity of the oil by rotating a blade in the lubricating oil and measuring the required torque. It can intuitively reflect the flow characteristics of the lubricating oil under rotational speed conditions.

[0004] However, in actual testing, the particulate impurities present in the lubricating oil may be residues that were not completely filtered out during the production process. These particulate impurities not only affect the fluidity of the lubricating oil, but may also interfere with the viscosity testing process, thus affecting the accuracy of viscosity measurement. In addition, if the lubricating oil is not sufficiently and uniformly mixed before testing, it may result in the oil being in an uneven state during testing, further aggravating the testing error.

[0005] In addition, although traditional rotational viscometers can effectively measure the viscosity of oil, their measurement results do not always accurately reflect the performance of lubricating oil in actual working environments. Rotational viscometers generally rely on the static fluidity of oil for measurement, while in actual use, the fluidity of lubricating oil is often affected by multiple factors such as temperature, pressure, and mechanical motion. Therefore, they cannot fully reflect the viscosity characteristics of oil in real working environments, resulting in certain deviations. Summary of the Invention

[0006] This invention provides a viscosity testing device for lubricating oil production. When using the testing device, particulate impurities in the lubricating oil are filtered to prevent impurities from interfering with the accurate measurement of viscosity, thereby improving the reliability of the measurement results. The filtration efficiency is also high, ensuring that the oil remains in a uniform state before testing, thus ensuring the accuracy of the viscosity test. When testing lubricating oil, it can reflect the true viscosity characteristics of the oil in the working environment, thereby improving the authenticity of lubricating oil testing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a viscosity testing device for lubricating oil production, the device comprising:

[0008] First processing tank;

[0009] Multiple positioning plates are fixedly installed on the inner wall of the first processing tank, and positioning rods are movably embedded in the inner wall of each of the multiple positioning plates. The multiple positioning rods can slide on the inner wall of the multiple positioning plates. By inserting the multiple positioning rods into the interior of the multiple positioning plates, the filter cartridge is installed inside the first processing tank. By pulling the filter cartridge, it can be removed from the interior of the first processing tank, at which time the filter cartridge can be cleaned.

[0010] A filter cartridge is fixedly mounted on one end of one of the multiple positioning rods, and a threaded rod is provided on one side of the filter cartridge via a bearing. The filter cartridge filters impurities in the lubricating oil, and the threaded rod can rotate via the bearing.

[0011] A sleeve is threaded onto the outer surface of the threaded rod, and a first pressure plate is fixedly fitted onto the outer surface of the sleeve. When the sleeve does not rotate with the threaded rod, the sleeve moves to different positions on the outer surface of the threaded rod.

[0012] The first magnet is fixedly disposed on the outer surface of the first pressure plate and is movably embedded in the inner wall of the filter cylinder. The first magnet can slide on the inner wall of the filter cylinder and has magnetic force.

[0013] As a further improvement of the present invention: a second pressure plate is movably embedded in the inner wall of the first processing tank, a second magnet is fixedly installed on the inner wall of the second pressure plate, and two sliders are fixedly installed on the outer surface of the second pressure plate. Two sliding grooves are formed in the inner wall of the first processing tank, and the two sliders are respectively slidably installed on the inner walls of the two sliding grooves. An oil inlet pipe is fixedly installed on one side of the first pressure plate. Multiple transmission rods are fixedly installed on the outer surface of the threaded rod, and a limiting plate is threadedly fitted on the outer surface of the threaded rod. Under the action of magnetic force, the first magnet and the second magnet attract each other, so that when the threaded rod rotates, the sleeve does not rotate with the threaded rod. Furthermore, the sleeve moves up and down on the outer surface of the threaded rod. At this time, the output shaft of the first motor is controlled to rotate in the forward direction, which further causes the multiple transmission rods to drive the threaded rod to rotate in the forward direction, further making... The sleeve drives the first pressure plate downwards. During the downward movement of the first pressure plate, the lubricating oil inside the filter cylinder is squeezed and splashes rapidly from the leakage hole on the top of the filter cylinder, improving the filtration efficiency. At the same time, some of the splashed lubricating oil flows into the interior of the second treatment tank, while some remains on the inner wall of the first treatment tank. As the first pressure plate moves downwards, it drives the first magnet to move, which in turn drives the second magnet to move. The second pressure plate can slide on the inner wall of the first treatment tank. The second magnet drives the second pressure plate to move downwards on the inner wall of the first treatment tank. The second pressure plate pushes the lubricating oil on the inner wall of the positioning plate, causing it to flow into the interior of the second treatment tank for processing. The limiting plate has a limiting effect on the first pressure plate, keeping the threaded rod stationary. By rotating the limiting plate, it can be removed from the threaded rod. At this time, the first pressure plate can be removed from the interior of the filter cylinder, and the impurities inside the filter cylinder can be cleaned.

[0014] As a further improvement of the present invention: a second processing tank is fixedly provided on one side of the first processing tank, a rotating plate is provided on one side of the second processing tank, a connecting rod is fixedly provided at the center of one side of the rotating plate, and a plurality of stirring rods are fixedly provided on the outer surface of the connecting rod. The rotation of the rotating plate further drives the connecting rod to rotate, and the rotation of the connecting rod drives the plurality of stirring rods to rotate. The plurality of stirring rods agitate the filtered lubricating oil and mix the different components of the oil evenly.

[0015] As a further improvement of the present invention: two connecting rods are fixedly provided on one side of the rotating plate, and hollow rods are fixedly provided on the opposite sides of the two connecting rods. Round rods are movably embedded in the inner walls of the two hollow rods, and the two round rods can slide on the inner walls of the two hollow rods respectively.

[0016] As a further improvement of the present invention: an arc-shaped plate is fixedly provided at one end of each of the two round rods, and a spring is fixedly provided on the opposite side of each of the two round rods. The two springs are fixedly provided on one side of the inner wall of the two hollow rods. The two springs have elastic force, and the elastic force of the two springs pushes the two round rods, further causing the two arc-shaped plates to be tightly attached to the inner wall of the second processing tank. When the two support plates rotate, they drive the two arc-shaped plates to rotate. The rotating two arc-shaped plates scrape the lubricating oil stuck to the inner wall of the second processing tank.

[0017] As a further improvement of the present invention: two L-shaped rods are fixedly installed on one side of the second processing tank, and a first motor is installed at one end of the two L-shaped rods. The output shaft of the first motor is fixedly installed on one side of the rotating plate. When the external power switch of the first motor is turned on, the two L-shaped rods support the first motor, and then the output shaft of the first motor drives the rotating plate to rotate.

[0018] As a further improvement of the present invention: a first conveying pipe is installed on one side of the second processing tank, a conveying pump is installed at one end of the first conveying pipe, a second conveying pipe is provided at the output end of the conveying pump, and a detection box is fixedly installed at one end of the second conveying pipe. When the switch of the conveying pump is turned on, the output end of the conveying pump generates suction, which draws the lubricating oil processed inside the second processing tank into the first conveying pipe, and discharges it into the interior of the second conveying pipe under the action of the conveying pump, and further discharges it into the interior of the detection box for detection.

[0019] As a further improvement of the present invention: a bidirectional lead screw is provided on the inner wall of the detection box via a bearing, and two square plates are threaded on the outer surface of the bidirectional lead screw. There are two threaded grooves with different directions of rotation on the outer surface of the bidirectional lead screw, and the two square plates are respectively connected to the two threaded grooves with different directions of rotation.

[0020] As a further improvement of the present invention: a guide plate is movably provided on one side of each of the two square plates, and a mounting seat is movably provided on one side of each of the two guide plates. A rotary viscometer is mounted on one side of the mounting seat. The two guide plates rotate about the connection point between the two square plates and the mounting seat. When the two square plates move relative to each other, the two guide plates push the mounting seat downward. When the two square plates move in opposite directions, the two guide plates pull the mounting seat upward, further driving the rotary viscometer to move. The rotary viscometer calculates the viscosity of the oil by measuring the required torque through the rotation of the blades in the oil.

[0021] As a further improvement of the present invention: a second motor is installed on one side of the detection box, the output shaft of the second motor is fixedly set at one end of the bidirectional lead screw, and the two square plates are slidably set on the inner wall of the detection box. The two square plates can slide on the inner wall of the detection box respectively, so that when the bidirectional lead screw rotates in different directions, the two square plates move in relative or opposite directions on the outer surface of the bidirectional lead screw. The output shaft of the second motor can rotate in both directions, and the bidirectional lead screw is driven to rotate back and forth by controlling the output shaft of the second motor.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0023] 1. This invention filters impurities in lubricating oil using a filter cylinder before testing its viscosity. As multiple stirring rods rotate, they impact multiple transmission rods, further driving them to rotate. This causes the sleeve to move the first pressure plate downwards. During this downward movement, the lubricating oil inside the filter cylinder is squeezed and splashes rapidly through the drain holes, improving filtration efficiency. Simultaneously, some of the splashed lubricating oil flows into the interior of the second processing tank, while some remains on the inner wall of the first processing tank. The downward movement of the first pressure plate moves the first magnet, which in turn moves the second magnet. The second pressure plate can slide along the inner wall of the first processing tank. The second magnet drives the second pressure plate downwards along the inner wall of the first processing tank. The second pressure plate pushes the lubricating oil on the inner wall of the positioning plate, causing it to flow into the second processing tank for processing. Therefore, during use, the equipment filters particulate impurities in the lubricating oil, preventing impurities from interfering with accurate viscosity measurement, improving the reliability of the measurement results, and achieving high filtration efficiency.

[0024] 2. In this invention, when testing lubricating oil, the external power switch of the first motor is turned on. The output shaft of the first motor drives the connecting rod to rotate, which in turn drives the connecting rod and the two support plates to rotate. When the connecting rod rotates, it drives multiple stirring rods to rotate. The multiple stirring rods agitate the filtered lubricating oil, uniformly mixing the different components of the oil, such as additives and base oil. The two round rods can slide on the inner walls of the two hollow rods respectively. The two springs have elastic force, and the elastic force of the two springs pushes the two round rods, further causing the two arc-shaped plates to be tightly attached to the inner wall of the second processing tank. When the two support plates rotate, they drive the two arc-shaped plates to rotate. The rotating two arc-shaped plates scrape the lubricating oil adhering to the inner wall of the second processing tank. When the rotating plates rotate, they scrape the lubricating oil on the bottom inner wall of the second processing tank, preventing additives or heavier components in the lubricating oil from adhering to the bottom or inner wall of the second processing tank. Thus, when testing the lubricating oil, the oil is kept in a uniform state before testing, ensuring the accuracy of the viscosity test.

[0025] 3. In this invention, after the lubricating oil treatment is completed, the treated lubricating oil in the second treatment tank is discharged into the testing chamber for testing. By controlling the output shaft of the second motor to drive the bidirectional lead screw to rotate back and forth, the two square plates move back and forth in the forward and reverse directions. The two guide plates rotate around the connection point between the two square plates and the mounting base. When the two square plates move relative to each other, the two guide plates push the mounting base downwards. When the two square plates move in opposite directions, the two guide plates pull the mounting base upwards. This causes the rotating blades on the rotary viscometer to move up and down inside the lubricating oil in the testing chamber, simulating the flow behavior of the oil in actual use. Therefore, when testing the lubricating oil, it can reflect the true viscosity characteristics of the oil in the working environment, improving the authenticity of the lubricating oil test.

[0035] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0037] Please see Figures 1 to 8This embodiment provides a viscosity testing device for lubricating oil production. The device includes: a first processing tank 1; multiple positioning plates 2, fixedly disposed on the inner wall of the first processing tank 1, with positioning rods 201 movably embedded in the inner walls of each positioning plate 2. The positioning rods 201 can slide along the inner walls of the positioning plates 2. By inserting the positioning rods 201 into the interior of the positioning plates 2, a filter cartridge 202 is installed inside the first processing tank 1. The filter cartridge 202 can be removed from the first processing tank 1 by pulling it, allowing for cleaning. The filter cartridge 202 is fixedly disposed at one end of each positioning rod 201. A threaded rod 203 is provided on one side via a bearing. Impurities in the lubricating oil are filtered through the filter cylinder 202. The threaded rod 203 can rotate via the bearing. A sleeve 204 is threaded onto the outer surface of the threaded rod 203, and a first pressure plate 205 is fixedly fitted onto the outer surface of the sleeve 204. When the sleeve 204 does not rotate with the threaded rod 203, the sleeve 204 moves to different positions on the outer surface of the threaded rod 203. A first magnet 206 is fixedly provided on the outer surface of the first pressure plate 205, and the first magnet 206 is movably embedded in the inner wall of the filter cylinder 202. The first magnet 206 can slide on the inner wall of the filter cylinder 202 and has magnetic force.

[0038] Please see Figures 1 to 8In one embodiment, a second pressure plate 207 is movably embedded in the inner wall of the first processing tank 1, a second magnet 208 is fixedly disposed on the inner wall of the second pressure plate 207, and two sliders 209 are fixedly disposed on the outer surface of the second pressure plate 207. Two grooves 210 are formed in the inner wall of the first processing tank 1, and the two sliders 209 are respectively slidably disposed in the inner walls of the two grooves 210. An oil inlet pipe 211 is fixedly disposed on one side of the first pressure plate 205, and multiple... A limiting plate 213 is threaded onto the outer surface of the transmission rod 212 and the threaded rod 203. Under the action of magnetic force, the first magnet 206 and the second magnet 208 attract each other. As a result, when the threaded rod 203 rotates, the sleeve 204 does not rotate with the threaded rod 203. Furthermore, the sleeve 204 moves up and down on the outer surface of the threaded rod 203. At this time, the output shaft of the first motor 308 is controlled to rotate in the forward direction, which further causes the multiple transmission rods 212 to drive the threaded rod 203 to rotate in the forward direction, and further causes the sleeve 204 to rotate. As the first pressure plate 205 moves downward, the lubricating oil inside the filter cylinder 202 is squeezed and splashes rapidly from the leak holes on the filter cylinder 202, improving the filtration efficiency. At the same time, some of the splashed lubricating oil flows into the interior of the second processing tank 3, while some remains on the inner wall of the first processing tank 1. When the first pressure plate 205 moves downward, it drives the first magnet 206 to move, which in turn drives the second magnet 208 to move. The second pressure plate 207 can slide on the inner wall of the first processing tank 1. The second magnet 208 drives the second pressure plate 207 to move downward on the inner wall of the first processing tank 1. The second pressure plate 207 pushes the lubricating oil on the inner wall of the positioning plate 2, causing it to flow into the interior of the second processing tank 3 for processing. The limiting plate 213 has a limiting effect on the first pressure plate 205, keeping the threaded rod 203 stationary. By rotating the limiting plate 213, the threaded rod 203 can be removed from the threaded rod 203. At this time, the first pressure plate 205 can be removed from the interior of the filter cylinder 202, and the impurities inside the filter cylinder 202 can be cleaned.

[0039] Please see Figures 1 to 8 In one embodiment, a second processing tank 3 is fixedly disposed on one side of the first processing tank 1, and a rotating plate 301 is disposed on one side of the second processing tank 3. A connecting rod 302 is fixedly disposed at the center of one side of the rotating plate 301, and a plurality of stirring rods 303 are fixedly disposed on the outer surface of the connecting rod 302. The rotation of the rotating plate 301 further drives the connecting rod 302 to rotate. When the connecting rod 302 rotates, it drives the plurality of stirring rods 303 to rotate. The plurality of stirring rods 303 agitate the filtered lubricating oil and mix the different components of the oil evenly.

[0040] Please see Figures 1 to 8In one embodiment, two connecting rods 302 are fixedly provided on one side of the rotating plate 301, and hollow rods 309 are fixedly provided on the opposite sides of the two connecting rods 302. Round rods 304 are movably embedded in the inner wall of the two hollow rods 309, and the two round rods 304 can slide on the inner wall of the two hollow rods 309 respectively.

[0041] Please see Figures 1 to 8 In one embodiment, an arc-shaped plate 305 is fixedly provided at one end of each of the two round rods 304, and a spring 306 is fixedly provided on the opposite side of each of the two round rods 304. The two springs 306 are fixedly provided on one side of the inner wall of the two hollow rods 309. The two springs 306 have elastic force, and the elastic force of the two springs 306 pushes the two round rods 304, further causing the two arc-shaped plates 305 to be tightly attached to the inner wall of the second processing tank 3. When the two support plates 310 rotate, they drive the two arc-shaped plates 305 to rotate. The rotating two arc-shaped plates 305 scrape the lubricating oil stuck to the inner wall of the second processing tank 3.

[0042] Please see Figures 1 to 8 In one embodiment, two L-shaped rods 307 are fixedly installed on one side of the second processing tank 3. A first motor 308 is installed at one end of the two L-shaped rods 307. The output shaft of the first motor 308 is fixedly installed on one side of the rotating plate 301. When the external power switch of the first motor 308 is turned on, the two L-shaped rods 307 support the first motor 308, and then the output shaft of the first motor 308 drives the rotating plate 301 to rotate.

[0043] Please see Figures 1 to 8 In one embodiment, a first conveying pipe 4 is installed on one side of the second processing tank 3. A conveying pump 401 is installed at one end of the first conveying pipe 4. A second conveying pipe 402 is provided at the output end of the conveying pump 401. A detection box 403 is fixedly installed at one end of the second conveying pipe 402. When the switch of the conveying pump 401 is turned on, the output end of the conveying pump 401 generates suction, which draws the lubricating oil processed inside the second processing tank 3 through the first conveying pipe 4. Under the action of the conveying pump 401, the oil is discharged into the second conveying pipe 402 and further discharged into the detection box 403 for detection.

[0044] Please see Figures 1 to 8 In one embodiment, a bidirectional lead screw 404 is provided on the inner wall of the detection box 403 via a bearing. Two square plates 405 are threaded on the outer surface of the bidirectional lead screw 404. There are two threaded grooves with different directions of rotation on the outer surface of the bidirectional lead screw 404. The two square plates 405 are respectively connected to the two threaded grooves with different directions of rotation.

[0045] Please see Figures 1 to 8In one embodiment, a guide plate 406 is movably disposed on one side of the two square plates 405, and a mounting base 407 is movably disposed on one side of the two guide plates 406. A rotary viscometer 408 is mounted on one side of the mounting base 407. The two guide plates 406 rotate about the connection point between the two square plates 405 and the mounting base 407. When the two square plates 405 move relative to each other, the two guide plates 406 push the mounting base 407 downward. When the two square plates 405 move in opposite directions, the two guide plates 406 pull the mounting base 407 upward, further driving the rotary viscometer 408 to move. The rotary viscometer 408 rotates in the oil by means of blades and measures the required torque to calculate the viscosity of the oil.

[0046] Please see Figures 1 to 8 In one embodiment, a second motor 409 is installed on one side of the detection box 403. The output shaft of the second motor 409 is fixedly disposed at one end of the bidirectional lead screw 404. Two square plates 405 are slidably disposed on the inner wall of the detection box 403. The two square plates 405 can slide on the inner wall of the detection box 403 respectively. Thus, when the bidirectional lead screw 404 rotates in different directions, the two square plates 405 move in relative or opposite directions on the outer surface of the bidirectional lead screw 404. The output shaft of the second motor 409 can rotate in both directions. By controlling the output shaft of the second motor 409, the bidirectional lead screw 404 is driven to rotate back and forth.

[0047] Working principle: When testing lubricating oil, the lubricating oil to be tested is poured into the filter cylinder 202 through the oil inlet pipe 211 by rotating the sealing cap on the oil inlet pipe 211. The lubricating oil flows into the second processing tank 3 through the leakage hole on the filter cylinder 202. The filter cylinder 202 filters the impurities in the lubricating oil. At this time, the external power switch of the first motor 308 is turned on. The two L-shaped rods 307 support the first motor 308, and then the output shaft of the first motor 308 drives the rotating plate 301 to rotate, which in turn drives the connecting rod 302 and the two support plates 310 to rotate. When the connecting rod 302 rotates, it drives multiple stirring rods 303 to rotate. The multiple stirring rods 303 agitate the filtered lubricating oil, separating the different components of the oil. The lubricating oil is mixed evenly. The two round rods 304 can slide on the inner walls of the two hollow rods 309 respectively. The two springs 306 have elastic force, which pushes the two round rods 304, further causing the two arc plates 305 to be tightly attached to the inner wall of the second processing tank 3. When the two support plates 310 rotate, they drive the two arc plates 305 to rotate. The rotating arc plates 305 scrape the lubricating oil adhering to the inner wall of the second processing tank 3. When the rotating plate 301 rotates, it scrapes the lubricating oil on the bottom inner wall of the second processing tank 3, preventing additives or heavier components in the lubricating oil from adhering to the bottom or inner wall of the second processing tank 3. Thus, when testing the lubricating oil, the oil is kept in a uniform state before testing, ensuring the accuracy of the viscosity test.

[0048] Before testing the viscosity of the lubricating oil, impurities in the oil are filtered through the filter cartridge 202. Multiple drive rods 212 are positioned in the gaps between multiple stirring rods 303. When the stirring rods 303 rotate, they impact the drive rods 212, further driving them to rotate. This, in turn, causes the threaded rod 203 to rotate. The two sliders 209 can slide on the inner walls of the two grooves 210. Both the second magnet 208 and the first magnet 206 possess magnetic force. Under the influence of this magnetic force, the first magnet 206 and the second magnet 208 attract each other. Therefore, when the threaded rod 203 rotates, the sleeve 204 does not rotate with it. The sleeve 204 moves up and down on the outer surface of the threaded rod 203. At this time, the output shaft of the first motor 308 is controlled to rotate in the forward direction, further causing the multiple drive rods 212 to drive the threaded rod 203 to rotate in the forward direction, further causing the sleeve 204 to rotate... The first pressure plate 205 moves downward. During this downward movement, the lubricating oil inside the filter cylinder 202 is squeezed and splashes rapidly from the leak holes on the filter cylinder 202, improving the filtration efficiency. At the same time, some of the splashed lubricating oil flows into the interior of the second processing tank 3, while some remains on the inner wall of the first processing tank 1. As the first pressure plate 205 moves downward, it drives the first magnet 206 to move, which in turn drives the second magnet 208 to move. The second pressure plate 207 can slide on the inner wall of the first processing tank 1. The second magnet 208 drives the second pressure plate 207 to move downward on the inner wall of the first processing tank 1. The second pressure plate 207 pushes the lubricating oil on the inner wall of the positioning plate 2, causing it to flow into the interior of the second processing tank 3 for processing. Thus, when the equipment is in use, particulate impurities in the lubricating oil are filtered to prevent impurities from interfering with the accurate measurement of viscosity, improving the reliability of the measurement results, and the filtration efficiency is high.

[0049] After the lubricating oil treatment is completed, the switch of the delivery pump 401 is turned on, and the output end of the delivery pump 401 generates suction, drawing the treated lubricating oil from the second treatment tank 3 through the first delivery pipe 4. Under the action of the delivery pump 401, it is discharged into the second delivery pipe 402, and further discharged into the detection box 403 for testing. The outer surface of the bidirectional lead screw 404 has two thread grooves with different helical directions. Two square plates 405 are connected to the two thread grooves with different helical directions, and the two square plates 405 can slide on the inner wall of the detection box 403. Thus, when the bidirectional lead screw 404 rotates in different directions, the two square plates 405 move in relative or opposite directions on the outer surface of the bidirectional lead screw 404. The output shaft of the second motor 409 can rotate in the opposite direction. The reverse rotation, controlled by the output shaft of the second motor 409, drives the bidirectional lead screw 404 to rotate back and forth, further causing the two square plates 405 to move back and forth in the forward and reverse directions. The two guide plates 406 rotate around the connection point between the two square plates 405 and the mounting base 407. When the two square plates 405 move relative to each other, the two guide plates 406 push the mounting base 407 downward. When the two square plates 405 move in opposite directions, the two guide plates 406 pull the mounting base 407 upward. This further causes the rotating blades on the rotary viscometer 408 to move up and down inside the lubricating oil in the test chamber 403, simulating the flow behavior of the oil in actual use. Thus, when testing lubricating oil, it can reflect the true viscosity characteristics of the oil in the working environment and improve the authenticity of lubricating oil testing.
