Description

Technical Field

[0001] The present invention mainly relates to the technical field of gear oil detection, and specifically relates to a long-life gear oil wear particle detection device and a detection method thereof. Background Art

[0002] Gear oil wear particles refer to hard particles present in gear oil. These hard particles are mixed into the gear oil during the gear oil production process or the gear lubrication process. The detection of wear particles in gear oil can not only reflect the oil contamination degree of the gear oil but also reflect the wear status of the equipment. Therefore, it is of great significance to regularly detect gear oil wear particles.

[0003] The existing gear oil wear particle detection device includes a housing, a first filter, a second filter, a third filter, a second weighing scale, a comparison device and a connecting plate. A feed port is installed on the top of the housing, a third filter is installed on the bottom of the rotating shaft, and a connecting plate bolt hole is provided on the connecting plate. The detection device is provided with a set of automatic filtering detection devices: after the user weighs the test material oil through the first weighing scale in the feed port and pours it into the detection device, the particles in the test material oil can be completely removed through sufficient filtration by the first filter, the second filter and the third filter. The remaining test material oil falls into the storage box through the discharge port. The second weighing scale and the comparison device on the storage box will weigh and compare it again. The whole set of operations is fully automatic and very efficient.

[0004] Existing products can filter out and weigh the wear particles in the oil, and automatically detect the content of wear particles in the gear oil. In reality, the distribution of wear particles in the working gear oil is not completely uniform. Too much total amount of wear particles per unit area will affect the normal use of the gear oil. Filtration and weighing can obtain the total weight data of wear particles in the gear oil, but it is not easy to understand the distribution of wear particles in the gear oil.

[0038] The following describes an embodiment of the present invention based on its overall structure.

[0040] It should be noted that, in this embodiment, when the wear particles in the gear oil are detected, a unit amount of the gear oil to be detected is first introduced into the detection tube 10 and the wear particles in the gear oil are captured in a plane to understand whether the amount of wear particles in the unit amount of the gear oil is within the set range. If the amount of wear particles in the unit amount of the gear oil is within the set range, a unit amount of the gear oil to be detected is continued to be introduced and the wear particles in the gear oil are captured in a three-dimensional manner to determine whether the amount of wear particles in the gear oil distributed in a unit space is within the set range.

[0041] When the wear particles in the gear oil are captured in a plane, a unit amount of the gear oil to be detected is passed into the detection tube 10.

The controller receives the image information captured by the mobile particle shooting component 25 and obtains the wear particle quantity information after analysis. When the wear particle quantity is lower than the set value, the wear particles are captured in three dimensions.

[0042] When the wear particles in the gear oil are captured three-dimensionally, a unit amount of the gear oil to be detected is passed into the detection tube 10. After the gear oil fills the detection tube 10, the moving plate 31 drives the three-dimensional filter plate 32 to enter the detection tube 10. The negative pressure suction component 33 works to absorb the gear oil. The wear particles are collected by the three-dimensional filter plate 32.

One end of the first electrically controlled valve 11 at the top is connected to the detection tube 10 through a pipeline, and the other end is connected to the oil inlet pipe and the recoil liquid discharge pipe. When the first electrically controlled valve 11 performs recoil operation, the recoil liquid pipe of the first electrically controlled valve 11 at the bottom is connected to the recoil liquid supply system, and the recoil liquid enters the detection tube 10 through the recoil liquid pipe and the first electrically controlled valve 11 at the bottom, and is then discharged through the first electrically controlled valve 11 at the top and the recoil liquid discharge pipe.

[0060] The working principle of the present invention is:

[0061] The electrical components in the present invention are all triggered to operate by the PLC controller;

[0062] When detecting the wear particles in the gear oil, firstly, a unit amount of the gear oil to be detected is introduced into the detection tube 10 and the wear particles in the gear oil are captured in a plane to understand whether the amount of the wear particles in the unit amount of the gear oil is within the set range. If the amount of the wear particles in the unit amount of the gear oil is within the set range, then a unit amount of the gear oil to be detected is continued to be introduced and the wear particles in the gear oil are captured in a three-dimensional manner to determine whether the amount of the wear particles in the gear oil distributed in a unit space is within the set range.

[0063] When the wear particles in the gear oil are captured in a plane, a unit amount of the gear oil to be detected is passed into the detection tube 10. After the unit amount of the gear oil to be detected passes through the mobile filter component 23, the wear particles in the gear oil are captured by the mobile filter component 23. The mobile filter component 23 for capturing the wear particles is removed from the detection tube 10, and the wear particles captured on the mobile filter component 23 are spread by the wear particle spreading component 24. After the spreading is completed, the wear particles are captured by the mobile particle shooting component 25. The controller receives the image information captured by the mobile particle shooting component 25 and obtains the wear particle quantity information after analysis. When the wear particle quantity is lower than the set value, the wear particles are captured in three dimensions.

[0064] When the wear particles in the gear oil are captured three-dimensionally, a unit amount of the gear oil to be detected is passed into the detection tube 10. After the gear oil fills the detection tube 10, the moving plate 31 drives the three-dimensional filter plate 32 to enter the detection tube 10. The negative pressure suction component 33 works to absorb the gear oil. The wear particles are collected by the three-dimensional filter plate 32. The moving plate 31 drives the three-dimensional filter plate 32 that captures the wear particles to move out of the detection tube 10. The three-dimensional shooting component 34 shoots each concave plate 323 in the three-dimensional filter plate 32. The controller receives the image information of the concave plate 323 shot by the three-dimensional shooting component 34 and obtains the image information of the wear particles on the concave plate 323 after analysis.

[0065] When the device is self-cleaning as a whole, the mobile filter component 23 is cleaned of wear particles by the particle suction component 26, the wear particles on the three-dimensional filter plate 32 are cleaned by the backwash component 35, and the detection tube 10 is backwashed by the two first electric control valves 11, so as to realize the self-cleaning of the entire device;

The wear particles are sucked through the suction plate 262 and the first suction pipe 263. During the suction process of the first suction pipe 263, the recoil liquid supply system connected to the first recoil pipe 265 can supply recoil liquid, and the recoil liquid is sprayed out through the filter hole at the top of the leak box 21 for recoil. The liquid after recoil can be sucked through the suction plate 262 and the first suction pipe 263;

[0067] When the backwash component 35 is working, the backwash liquid supply system connected to the second backwash pipe 351 can supply the backwash liquid, and the flushing liquid passes through the third electric control valve 336, the connecting pipe 331, the drainage channel 334 and the drainage cavity 333 to backwash the three-dimensional filter plate 32, and the backwashed liquid is discharged through the fourth electric control valve 337 and the drainage pipe 352;

[0068] One end of the first electrically controlled valve 11 at the bottom is connected to the detection tube 10 through a pipeline, and the other end is connected to the oil discharge pipe and the recoil liquid pipe. One end of the first electrically controlled valve 11 at the top is connected to the detection tube 10 through a pipeline, and the other end is connected to the oil inlet pipe and the recoil liquid discharge pipe. When the first electrically controlled valve 11 performs recoil work, the recoil liquid pipe of the first electrically controlled valve 11 at the bottom is connected to the recoil liquid supply system, and the recoil liquid enters the detection tube 10 through the recoil liquid pipe and the first electrically controlled valve 11 at the bottom, and then is discharged through the first electrically controlled valve 11 at the top and the recoil liquid discharge pipe.

[0069] When the movable filter component 23 is working, when the gear oil passes through the plane filter plate 231, the plane filter plate 231 can filter out the wear particles. When the plane filter plate 231 moves out of the detection tube 10, the electric cylinder 233 performs the work, and the electric cylinder 233 drives the extension plate 232 and the plane filter plate 231 to move;

[0070] When the wear particle spreading component 24 is working, the liquid supply pipe 244 is connected to the liquid supply system, and the liquid supply system discharges the supply liquid into the liquid supply pipe 244. The supply liquid is mixed with the wear particles after passing through the liquid injection pipe 243, the filter holes on the leak box 21 and the flat filter plate 231. The execution end of the bidirectional linear module 241 drives the distribution plate 242 to move in directions away from each other to spread the supply liquid mixed with the wear particles. After the spreading is completed, the negative pressure system connected to the second suction pipe 264 starts to work, and the supply liquid is filtered and sucked out by the leak box 21 to complete the spreading of the wear particles.

[0071] When the movable particle shooting component 25 is working, the execution end of the first linear module 251 drives the translation plate 252 to move, and the translation plate 252 drives the first camera 253 to move, and the first camera 253 shoots the wear particles on the leak box 21 and the plane filter plate 231;

[0072] When the negative pressure suction component 33 is working, the negative pressure system connected to the negative pressure pipe 335 starts to work, and the gear oil is sucked out through the drainage chamber 333, the drainage channel 334, the connecting pipe 331, the third electric control valve 336 and the negative pressure pipe 335. During the suction process, the fourth electric control valve 337 switches to connect the detection pipe 10 with the air pipe 338, and the air can enter the detection pipe 10 through the air pipe 338 and the fourth electric control valve 337;

[0073] When the three-dimensional shooting component 34 is working, after the three-dimensional filter plate 32 completes the three-dimensional capture of wear particles, the first pneumatic cylinder drives the moving plate 31 to move so that the three-dimensional filter plate 32 moves out of the detection tube 10, and the second pneumatic cylinder drives the driving plate 341 to move so that the mounting cover 342 moves to the top of the three-dimensional filter plate 32, and the micro motor 343 is turned on.
