Description

Technical Field

[0001] This utility model belongs to the field of hydraulic filter testing technology, and in particular relates to a hydraulic filter filtration performance testing device. Background Technology

[0002] Hydraulic filter performance testing devices are specialized equipment used to evaluate the key performance characteristics of filters in hydraulic systems. Their main testing items include filtration accuracy (β value), pressure drop characteristics, dirt holding capacity, multiple pass test, and bubble point test. Filtration accuracy is measured by the β value; for example, β5=200 indicates a 99.5% interception efficiency for 5μm particles. Pressure drop characteristics measure the pressure loss of the filter at different flow rates, while dirt holding capacity reflects the maximum mass of contaminants the filter element can retain before clogging. The multiple pass test simulates long-term performance under actual working conditions, and the bubble point test is used to determine the maximum pore size of high-precision filter elements. However, hydraulic filter performance testing devices still have the following drawbacks in practical use:

[0003] When the hydraulic filter performance testing device is in operation, it directly uses the filter structure to filter and then tests the condition of the filtered oil. However, testing the condition of the filtered oil requires multiple tests, and determining the cleanliness of the filtered oil requires the operator to place the oil under a light and observe it with the naked eye, which is not very accurate.

[0004] Secondly, during the testing process of the hydraulic filter performance testing device, the filter to be tested needs to be installed on the testing device. However, when different filters are tested, the filter is directly installed at the input end of the filter. The filter being tested does not have good support, which can easily bend the pipeline at the input end of the testing device and affect the durability of the testing device. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic filter filtration performance testing device. By setting up a working platform, support plate, mounting box and testing components, it solves the problem that the hydraulic filter filtration performance testing device relies solely on visual observation of the cleanliness of the tested oil, which has low accuracy, and there is no good support for the filter during the test.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a hydraulic filter performance testing device, comprising a working platform, a support plate, a mounting box, and a testing component. The mounting box is fixed to one short side of the top of the working platform. A second lens is fixed through the center of the bottom of the mounting box, and a laser pointer is fixed to the center of the bottom of the mounting box, with the light-emitting end of the laser pointer aligned with the second lens. A testing component is disposed through one side of the mounting box. The testing component includes a third lens and a photosensitive switch. A photosensitive switch is located at one end of the third lens and is positioned outside the testing component. A T-shaped slide rail is mounted on the top of the working platform on one side of the mounting box, and a support plate is mounted on the top of the T-shaped slide rail. During operation, the working platform supports the support plate, the mounting box, and the testing component. The filter to be tested is supported on the support plate. The filtered solution is transported through the mounting box, and the testing component detects and determines the heat dispersed by the laser within the oil passing through the mounting box.

[0008] Furthermore, the bottom of the work platform is provided with two electric push rods, the telescopic ends of which both of the electric push rods pass through the work platform and are fixed to the bottom of the T-shaped slide rail. During operation, the work platform drives the T-shaped slide rail to move up and down through the electric push rods.

[0009] Furthermore, L-shaped sliding plates are fixed at both long sides of the bottom of the support plate. The two L-shaped sliding plates are symmetrically arranged and are movably connected to the lower parts of both sides of the T-shaped slide rail. The support plate is restricted to movingly connecting with the T-shaped slide rail by the L-shaped sliding plates.

[0010] Furthermore, the top of the T-shaped slide rail has two parallel sliding grooves. The support plate is threaded with clamping bolts corresponding to the positions of the two sliding grooves. The two clamping bolts pass through the support plate and enter the sliding grooves, and are clamped at the bottom of the sliding grooves. The T-shaped slide rail is clamped by the clamping bolts through the sliding grooves, so that the T-shaped slide rail and the clamping bolts are limited.

[0011] Furthermore, a lens is fixedly installed through the center of the top of the mounting box, and connecting pipes are fixedly connected to the center of both ends of the mounting box. A mounting ring is fixed to the end of each connecting pipe away from the mounting box. The lens on the mounting box transmits light from the laser pointer passing through the mounting box.

[0012] Furthermore, the detection assembly also includes a warning light. The lens three is fixedly fixed to one side of the mounting box, and the end of the photosensitive switch away from the lens three is fixed with a warning light. When the detection assembly is working, the warning light is turned on to determine that the turbidity of the filtered oil is too high and the filtration cleanliness is insufficient.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of low accuracy in hydraulic filter performance testing devices that rely solely on visual observation of the cleanliness of the tested oil by setting up a working platform, mounting box, and testing components. During operation, after the filter is installed and a stable flow of oil is achieved through the connecting pipe, the laser pointer is activated. The light emitted by the laser pointer passes through lens two and the oil flowing through the mounting box before exiting through lens one. When the tested oil is too turbid, the Tyndall effect occurs after the turbid oil is transported to the mounting box, dispersing the laser beam emitted by the laser pointer. The beam then passes through lens three and illuminates a photosensitive switch, triggering a warning light that flashes, indicating that the filter's performance is substandard. This allows for a more accurate and reliable assessment of the filter's performance during operation.

[0015] This invention solves the problem of inadequate support for filters during hydraulic filter performance testing by setting up a working platform, support plate, and mounting box. First, the position of the filter's output end is determined. The filter is placed on the support plate, and the electric push rod is activated to lift the T-shaped slide rail and support plate until the height of the filter's output end is flush with the height of the connecting pipe. Then, the filter is removed, the clamping bolts are loosened, and the filter is placed back on the support plate with its output end aligned with the mounting box. The support plate and filter are slid until the filter's output end aligns with the mounting ring on the connecting pipe near the support plate side of the mounting box. The filter is then removed and tightened, ensuring proper support for the filter during hydraulic filter performance testing. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please refer to Figure 1-4 This utility model is a hydraulic filter performance testing device, including a working platform 1, a support plate 2, a mounting box 3, and a testing component 4. The mounting box 3 is fixed to one short side of the top of the working platform 1. The working platform 1 supports the support plate 2, the mounting box 3, and the testing component 4 on it. The mounting box 3 is used for the flow of oil filtered by the filter. A lens 303 is fixed through the center of the bottom of the mounting box 3, allowing laser light emitted by a laser pointer 302 to pass through into the mounting box 3. The laser pointer 302 is fixed to the center of the bottom of the mounting box 3, with its emitting end aligned with the lens 303, emitting a detection laser. The testing component 4 is installed through one side of the mounting box 3. The detection component 4 detects whether the oil passing through the installation box 3 is too turbid. The detection component 4 includes a lens 3 401 and a photosensitive switch 402. The photosensitive switch 402 is set at one end of the lens 3 401 and is set on the outside of the detection component 4. When the oil being detected is too turbid, the turbid oil is transported into the installation box 3, and the Tyndall effect occurs, which disperses the laser emitted by the laser pointer 302, passes through the lens 3 401, and shines on the photosensitive switch 402. A T-shaped slide rail 102 is set on the top of the working platform 1 on one side of the installation box 3. The T-shaped slide rail 102 supports the support plate 2 on it. The support plate 2 is set on the top of the T-shaped slide rail 102, and the support plate 2 provides support for the filter being tested.

[0026] Specifically, two electric push rods 101 are installed at the bottom of the work platform 1. The telescopic ends of the two electric push rods 101 are both installed through the work platform 1 and fixed to the bottom of the T-shaped slide rail 102. The two electric push rods 101 are controlled by the same controller to work synchronously. When the work platform 1 is working, the electric push rods 101 drive the T-shaped slide rail 102 to rise and fall, thereby adjusting the height of the T-shaped slide rail 102.

[0027] Furthermore, L-shaped sliding plates 202 are fixed at both long sides of the bottom of the support plate 2. The two L-shaped sliding plates 202 are symmetrically arranged and are movably connected to the lower sides of the T-shaped slide rail 102. When the support plate 2 is working, the L-shaped sliding plates 202 movably connect the support plate 2 and the T-shaped slide rail 102.

[0028] Furthermore, the top of the T-shaped slide rail 102 has two parallel sliding grooves 103. The support plate 2 is threadedly connected to the two sliding grooves 103. The two clamping bolts 201 pass through the support plate 2 and enter the sliding grooves 103, and are clamped at the bottom of the sliding grooves 103. When the T-shaped slide rail 102 is in operation, after the clamping bolts 201 are screwed into the support plate 2, the clamping bolts 201 enter the sliding grooves 103 and are clamped at the bottom of the sliding grooves 103, so that the position between the T-shaped slide rail 102 and the support plate 2 is restricted and determined.

[0029] The operation process of this embodiment is as follows: During operation, first determine the position of the output end of the filter to be tested, place the filter on the support plate 2, start the electric push rod 101 to drive the T-shaped slide rail 102 and the support plate 2 to rise until the height of the filter output end is level with the height of the connecting pipe 304. Then remove the filter, loosen the clamping bolt 201, place the filter on the support plate 2, align the output end with the mounting box 3, slide the support plate 2 and the filter until the filter output end is aligned with the mounting ring 305 on the connecting pipe 304 near the support plate 2 of the mounting box 3, remove the filter, rotate the clamping bolt 201 again until the clamping bolt 201 is pressed against the bottom of the sliding groove 103 on the working platform 1, put the filter back on, connect the pipeline for the external input oil of the filter, and install the output end of the filter with the mounting ring 305 on the connecting pipe 304 near the support plate 2 of the mounting box 3 to complete the work. Specific Implementation Example 2

[0030] Please see Figure 1 , 45. Based on the specific embodiment one, a lens 301 is fixedly fixed through the center of the top of the mounting box 3. A connecting pipe 304 is fixedly connected to the center of both ends of the mounting box 3. A mounting ring 305 is fixed to the end of each connecting pipe 304 away from the mounting box 3. When the mounting box 3 is working, the light emitted by the laser pointer 302 passes through the lens 303 and the oil that passes through the mounting box 3 and then passes through the lens 301. The mounting ring 305 on the connecting pipe 304 near the support plate 2 of the mounting box 3 is installed with the output end of the filter under test. The mounting ring 305 on the connecting pipe 304 away from the support plate 2 of the mounting box 3 is connected with the equipment for collecting the tested oil.

[0031] Specifically, the detection component 4 also includes a warning light 403. Lens 3 401 is fixedly mounted on one side of the mounting box 3. The end of the photosensitive switch 402 away from the lens 3 401 is fixed with the warning light 403. The photosensitive switch 402 and the warning light 403 are electrically connected. The photosensitive switch 402 controls the opening and closing of the warning light 403. When the detection component 4 is working, when the brightness of the light transmitted through the lens 3 401 increases, the photosensitive switch 402 turns on the warning light 403, indicating that the filter's filtration performance is unqualified.

[0032] The operation process of this embodiment is as follows: During operation, after the filter and the installation box 3 are installed, the mounting ring 305 on the connecting pipe 304 at the end of the installation box 3 away from the support plate 2 is connected to the pipeline for recovering oil. The oil can then be transported to the filter for filtration and transported to the installation box 3 through the connecting pipe 304 near the support plate 2. It is then transported to another connecting pipe 304 through the installation box 3 and recovered through the recovery pipeline. When a stable amount of oil is output from the connecting pipe 304, the laser pointer 302 is turned on. The light emitted by the laser pointer 302 passes through the lens 2 303 and the oil passing through the installation box 3 and is then transmitted through the lens 1 301. When the detected oil is too turbid, the Tyndall effect occurs after the turbid oil is transported to the installation box 3, which disperses the laser emitted by the laser pointer 302. The laser passes through the lens 3 401 and illuminates the photosensitive switch 402. The photosensitive switch 402 turns on the warning light 403, which flashes to indicate that the filter's filtration performance is substandard.
