Description

Technical Field

[0001] This utility model relates to the field of hydraulic contamination detection, and in particular to a device for testing the contamination tolerance of hydraulic components. Background Technology

[0002] Most hydraulic system failures are caused by oil contamination. Solid particulate matter is a common and highly hazardous contaminant in hydraulic systems. Regularly testing the particulate matter content in the hydraulic fluid can not only improve the reliability and extend the service life of the hydraulic system, but also reduce the accident rate, improve safety and production efficiency, and facilitate timely oil replacement. This allows the hydraulic fluid to reach its maximum value while ensuring safety, thereby improving economic benefits.

[0003] Currently, existing oil contamination detection equipment extracts oil from hydraulic components, then transmits light through the oil via a light-emitting element, and a photosensitive element receives the light. Based on the intensity of the light received by the photosensitive element, the signal is transmitted to a signal processor to determine the transmittance of the oil, thereby reflecting the degree of oil contamination. However, after the oil is extracted, the uneven distribution of contaminant particles in the oil leads to deviations in the detection results. Furthermore, it is inconvenient to clean the residual oil on the inner wall of the equipment, affecting its future use.

[0004] Therefore, we propose a device for testing the contamination tolerance of hydraulic components. Utility Model Content

This utility model proposes a hydraulic component contamination tolerance testing device, which solves the problem that after the oil is extracted, the uneven distribution of contaminant particles in the oil leads to deviations in the test results, and it is also inconvenient to clean the oil residue on the inner wall of the device, which affects the next use.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a hydraulic component contamination tolerance testing device, comprising: a testing cylinder, a stirring assembly, and a sealing assembly. A liquid inlet pipe is fixedly connected to the top of the testing cylinder, and a testing tube is fixedly connected to the bottom of the testing cylinder. A light-emitting element and a photosensitive element are respectively arranged on both sides of the testing tube. The stirring assembly includes a hollow tube rotatably mounted on the top of the testing cylinder and a driving assembly for driving the hollow tube to rotate. A stirring blade is fixedly connected to the surface of the hollow tube, and scraper frames are fixedly connected to both sides of the hollow tube. The sealing assembly includes a connecting rod movably penetrating inside the hollow tube and a lifting assembly for driving the connecting rod to rise and fall. A sealing plate is fixedly connected to the lower end of the connecting rod.

[0007] Preferably, the detection tube is a transparent tube.

[0008] Preferably, the drive assembly includes a first motor fixedly mounted on the detection cylinder, a main gear fixedly mounted on the output end of the first motor, and a driven gear fixedly mounted on the upper end of the hollow tube, wherein the main gear meshes with the driven gear.

[0009] Preferably, the lifting assembly includes a housing fixedly installed on the top of the detection cylinder, a second motor fixedly installed on the top of the housing, a screw fixedly installed on the output end of the second motor, and a connecting plate threadedly connected to the screw. The screw is rotatably installed inside the housing, and the connecting plate is fixedly connected to the upper end of the connecting rod.

[0010] Preferably, a guide rod is fixedly installed inside the outer casing, and the connecting plate is slidably sleeved on the guide rod.

[0011] Preferably, sealing rings are embedded at both ends of the hollow tube.

[0012] Preferably, a collection tube is provided at the bottom of the detection tube, and the lower end of the detection tube extends into the collection tube.

[0013] Preferably, the collection tube is equipped with buckles around its perimeter, and the collection tube is fixed to the detection tube by the buckles.

[0014] Compared with the prior art, the beneficial effects of this utility model include:

[0015] By setting up a stirring assembly, before oil testing, the first motor can be started to drive the main gear to rotate, which in turn drives the driven gear to rotate. The driven gear then drives the hollow tube to rotate, which in turn drives the stirring blades and scraper frame to rotate. The stirring blades stir the oil, ensuring that the contaminant particles in the oil are evenly distributed, thus improving the reliability of the test results. The scraper frame cleans the inner wall of the testing cylinder, preventing oil residue from remaining on the inner wall of the testing cylinder and affecting the next use.

[0016] By setting up a sealing assembly, the sealing plate blocks the upper end of the detection tube when the oil is being stirred, preventing oil from entering the detection tube. During testing, the second motor can be started to drive the screw to rotate, causing the screw to slide the connecting plate along the guide rod. The connecting plate then drives the connecting rod to rise, causing the connecting rod to move the sealing plate out of the detection tube, allowing the oil to enter the detection tube for testing. After testing, the sealing plate can be slid inside the detection tube via the connecting plate to clean the inner wall of the detection tube, preventing oil residue from affecting the next use.

The testing tube 12 is a transparent tube. A light-emitting element 13 and a photosensitive element 14 are respectively arranged on both sides of the testing tube 12. By setting up the testing cylinder 1, the oil to be tested can be drawn from the inlet pipe 11 into the testing cylinder 1. The oil flows through the testing tube 12. The light-emitting element 13 emits light that penetrates the oil, and the photosensitive element 14 receives the light. Based on the intensity of the light received by the photosensitive element, the signal is transmitted to a signal processor to determine the transmittance of the oil, thereby reflecting the degree of contamination of the oil and realizing the detection of the contamination tolerance of the hydraulic component.

[0027] Furthermore, a collection cylinder 15 is provided at the bottom of the detection cylinder 1, and the lower end of the detection tube 12 extends into the collection cylinder 15. Fasteners 16 are installed around the collection cylinder 15, and the collection cylinder 15 is fixed to the detection cylinder 1 by the fasteners 16. By setting the collection cylinder 15, oil can be collected.

[0028] Reference Figure 2 and Figure 3 The stirring assembly 2 includes a hollow tube 21 rotatably mounted on the top of the detection cylinder 1 and a drive assembly 22 for driving the hollow tube 21 to rotate. Stirring blades 23 are fixedly connected to the surface of the hollow tube 21, and scraper frames 24 are fixedly connected to both sides of the hollow tube 21. The drive assembly 22 includes a first motor 221 fixedly mounted on the detection cylinder 1, a main gear 222 fixedly mounted on the output end of the first motor 221, and a driven gear 223 fixedly mounted on the upper end of the hollow tube 21. The main gear 222 meshes with the driven gear 223, and the rotation is achieved through... The stirring assembly 2 is installed so that before oil testing, the first motor 221 can be started to drive the main gear 222 to rotate, which in turn drives the driven gear 223 to rotate. The driven gear 223 drives the hollow tube 21 to rotate, which in turn drives the stirring blade 23 and the scraper frame 24 to rotate. The stirring blade 23 stirs the oil, making the contaminant particles in the oil evenly distributed and improving the reliability of the test results. The scraper frame 24 cleans the inner wall of the test cylinder 1 to prevent oil residue from remaining on the inner wall of the test cylinder 1 and affecting the next use.

[0029] Reference Figure 2 and Figure 3 The sealing assembly 3 includes a connecting rod 31 that moves through the hollow tube 21 and a lifting assembly 32 for driving the connecting rod 31 to rise and fall. A sealing plate 33 is fixedly connected to the lower end of the connecting rod 31. The lifting assembly 32 includes a housing 321 fixedly installed on the top of the detection cylinder 1, a second motor 322 fixedly installed on the top of the housing 321, a screw 323 fixedly installed on the output end of the second motor 322, and a connecting plate 324 threadedly connected to the screw 323. The screw 323 is rotatably installed inside the housing 321. The connecting plate 324 is fixedly connected to the upper end of the connecting rod 31. A guide rod 325 is fixedly installed inside the housing 321. The connecting plate 324 is slidably sleeved on the guide rod 325. By setting the sealing component 3, when the oil is stirred, the sealing plate 33 blocks the upper end of the detection tube 12, which can prevent the oil from entering the detection tube 12. During the test, the second motor 322 can be started to drive the screw 323 to rotate, so that the screw 323 drives the connecting plate 324 to slide along the guide rod 325. The connecting plate 324 drives the connecting rod 31 to rise, so that the connecting rod 31 drives the sealing plate 33 to move out of the detection tube 12, so that the oil can enter the detection tube 12 for testing. After the test, the sealing plate 33 can be slid in the detection tube 12 by the connecting plate 324 to clean the inner wall of the detection tube 12, so as to avoid oil residue on the inner wall of the detection tube 12 affecting the next use.

[0030] Furthermore, sealing rings 25 are embedded at both ends of the hollow tube 21. By setting the sealing rings 25, oil can be prevented from entering the hollow tube 21.

[0031] In practical use, the working principle of this utility model is as follows:

[0032] First, the oil to be tested can be drawn from the inlet pipe 11 into the detection cylinder 1. The sealing plate 33 is placed on the upper end of the detection tube 12 to prevent the oil from entering the detection tube 12. The first motor 221 is started to drive the main gear 222 to rotate, which in turn drives the driven gear 223 to rotate. The driven gear 223 drives the hollow tube 21 to rotate, which in turn drives the stirring blade 23 and the scraper frame 24 to rotate. The stirring blade 23 stirs the oil, making the contaminant particles in the oil evenly distributed and improving the reliability of the test results. The scraper frame 24 cleans the inner wall of the detection cylinder 1.

[0033] During testing, the second motor 322 can be started to drive the screw 323 to rotate, causing the screw 323 to drive the connecting plate 324 to slide along the guide rod 325. The connecting plate 324 drives the connecting rod 31 to rise, causing the connecting rod 31 to drive the sealing plate 33 to move out of the detection tube 12, allowing the oil to enter the detection tube 12. As the oil flows through the detection tube 12, the light-emitting element 13 emits light that penetrates the oil, and the photosensitive element 14 receives the light. Based on the intensity of the light received by the photosensitive element, the signal is transmitted to the signal processor to determine the light transmittance of the oil, thereby reflecting the degree of oil contamination and realizing the detection of the contamination tolerance of hydraulic components.

[0034] After the test is completed, the sealing plate 33 can be slid inside the test tube 12 by the connecting plate 324 to clean the inner wall of the test tube 12 and prevent oil residue from remaining on the inner wall of the test tube 12 and affecting the next use.

[0035] In summary, this hydraulic component contamination tolerance testing equipment, by setting up a stirring component 2, can stir the oil before testing, so that the contaminant particles in the oil are evenly distributed, improving the reliability of the test results. The scraper frame 24 cleans the inner wall of the testing cylinder 1, preventing oil residue from remaining on the inner wall of the testing cylinder 1 and affecting the next use.
