Description

Technical Field

[0001] The invention relates to the technical field of filter detection devices, and in particular to an automobile filter assembly detection device and a detection method. Background Art

[0002] When the oil in the motor cools the motor, the gradually increasing temperature of the oil will form vapor, so the oil needs to be separated from the water through the filter, and then cooled by the cooling module. In order to ensure the cooling effect of the oil on the motor, the oil-water separation performance and heat exchange efficiency of the filter and the oil cooling module need to be tested through a detection device.

[0003] When the motor is working, the heat generated is different due to different loads and working times, so the temperature of the oil will also change after heat exchange with the heat on the motor. However, in the prior art, there is no device for detecting the oil-water separation performance and heat exchange efficiency of the filter and the oil cooling module by simulating different states of the motor. As a result, it is impossible to analyze the cooling performance of the oil through the oil-water separation performance of the filter and the heat exchange efficiency of the cooling module under different working states of the motor, resulting in low accuracy of the data obtained when detecting the filter and the oil cooling module.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a vehicle filter assembly detection device and a detection method.

[0043] See also Figure 1-9 A vehicle filter assembly detection device comprises a detection box 1, wherein a heating component 2 and a cooling circulation component 3 are arranged inside the detection box 1, oil circulation components 4 are arranged at both ends of the heating component 2, a detection platform 5 is fixedly installed on the front of the detection box 1, a component to be tested 6 is arranged on the top of the detection platform 5, the cooling circulation component 3 and the oil circulation component 4 are both connected to the component to be tested 6, the cooling circulation component 3 and the oil circulation component 4 are both provided with a temperature measuring component 7, and the oil circulation component 4 is provided with a concentration detection component 8.

[0044] The heating component 2 is used to heat the engine oil, the oil circulation component 4 is used to guide the engine oil so that the engine oil flows through the component to be tested 6, the cooling circulation component 3 is used to cool the component to be tested 6, the temperature measuring component 7 is used to measure the temperature of the medium inside the oil circulation component 4 and the cooling circulation component 3, and the concentration detection component 8 is used to detect the moisture inside the oil circulation component 4.

[0045] The engine oil is heated by the heating component 2, and the heated engine oil can circulate inside the component to be tested 6 with the assistance of the oil circulation component 4. At the same time, the component to be tested 6 can separate the oil and water in the engine oil. At the same time, the cooling water can also flow inside the component to be tested 6 with the assistance of the cooling circulation component 3, so that the cooling water and the engine oil can exchange heat inside the component to be tested 6. At this time, the temperature measuring component 7 can measure the temperature of the engine oil and the cooling water when they flow into the component to be tested 6 and when they flow out of the component to be tested 6. When the engine oil flows into the heating component 2 again, the concentration detection component 8 can measure the water content in the engine oil.

[0046] The engine oil is heated by the heating component 2 to simulate the temperature of the engine oil after absorbing heat under different operating conditions of the motor. At the same time, the engine oil and cooling water can continuously flow inside the component to be tested 6 through the cooling circulation component 3 and the oil circulation component 4. At this time, several temperature measuring components 7 can detect the temperature of the engine oil and cooling water flowing in and out of the component to be tested 6, and the concentration detection component 8 can measure the concentration of the engine oil. In summary, it is only necessary to heat the engine oil to different temperatures through the heating component 2 to detect the oil-water separation performance and heat exchange efficiency of the filter and the oil cooling module under different operating conditions of the engine, so that the data when detecting the component to be tested is more accurate.

[0047] Furthermore, for the above-mentioned heating component 2, the heating component 2 includes a heating box 201, the heating box 201 is arranged inside the detection box 1, a heating plate 202 is arranged inside the heating box 201, an observation slot 203 is opened on the front of the heating box 201, an oil filling pipe 204 is fixedly connected to the front of the heating box 201, a funnel 205 is fixedly installed on the top of the oil filling pipe 204, and a sealing cover 206 is threadedly connected to the top of the funnel 205.

[0048] The oil stored in the heating box 201 can be heated by the heating plate 202. At the same time, a plurality of heating plates 202 are arranged in the heating box 201 array. This arrangement allows the plurality of heating plates 202 to better heat the flowing oil when the oil circulates. The oil in the heating box 201 can be checked through the observation slot 203. When there is not much oil in the heating box 201, the oil can be added to the inside of the heating box 201 through the funnel 205 and the oil adding pipe 204. At the same time, the sealing cover 206 can seal the funnel 205, so that the sealing inside the heating box 201 can be guaranteed.

[0049] Furthermore, for the above-mentioned cooling cycle component 3, the cooling cycle component 3 includes a mounting frame 301, the mounting frame 301 is fixedly installed on the inner wall of the detection box 1, and a cooling tower 302 is fixedly installed on the top of the mounting frame 301. One side of the cooling tower 302 is fixedly connected to a water outlet pipe 303, and the other side of the cooling tower 302 is fixedly connected to a water inlet pipe 304. The water outlet pipe 303 and the water inlet pipe 304 are both connected to the component to be tested 6.

[0050] The cooling water inside the cooling tower 302 can flow into the interior of the component to be tested 6 through the outlet pipe 303. After the cooling water completes heat exchange inside the component to be tested 6, it flows into the interior of the cooling tower 302 again under the guidance of the inlet pipe 304. At this time, the cooling tower 302 can cool the cooling water. The cooling water that has completed cooling flows into the interior of the component to be tested 6 again through the outlet pipe 303. This arrangement allows the cooling water to be circulated and utilized when the component to be tested 6 is tested.

[0051] Furthermore, for the above-mentioned oil circulation component 4, the oil circulation component 4 includes an oil pump 401, the oil pump 401 is fixedly installed inside the detection box 1, the extraction end of the oil pump 401 is fixedly connected with an extraction pipe 402, the extraction pipe 402 is fixedly connected to one side of the heating box 201, the oil outlet end of the oil pump 401 is fixedly connected with an oil outlet pipe 403, and the other side of the heating box 201 is fixedly connected with an oil inlet pipe 404, and the oil outlet pipe 403 and the oil inlet pipe 404 are both connected to the component to be tested 6.

[0052] The oil pump 401 extracts the engine oil inside the heating box 201 through the extraction pipe 402, and the extracted engine oil flows to the inside of the component to be tested 6 under the guidance of the oil outlet pipe 403. After the engine oil completes oil-water separation and heat exchange inside the component to be tested 6, it flows to the inside of the heating box 201 again under the guidance of the oil inlet pipe 404. At this time, the heating plate 202 inside the heating box 201 heats the engine oil to a suitable temperature, and then flows out of the heating box 201 again through the extraction pipe 402.

[0053] Furthermore, for the above-mentioned component to be tested 6, the component to be tested 6 includes a cooling module 601, and the cooling module 601 is arranged on the top of the testing platform 5. A filter 602 is fixedly connected to one side of the cooling module 601, and a connecting pipe 603 is fixedly connected to one side of the filter 602. One end of the connecting pipe 603 is fixedly connected to the cooling module 601. A clamping plate 604 is fixedly connected to the cooling module 601 at the top of the testing platform 5 corresponding to the cooling module 601. The water outlet pipe 303, the water inlet pipe 304 and the oil inlet pipe 404 are all connected to the cooling module 601, and the oil outlet pipe 403 is connected to the filter 602.

[0054] By placing the cooling module 601 on the top of the testing table 5, the clamping plate 604 on the testing table 5 can support the cooling module 601, so that the cooling module 601 will not fall over at will, and then the water outlet pipe 303, the water inlet pipe 304 and the oil inlet pipe 404 are connected to the corresponding connection ports on the cooling module 601, and one end of the oil outlet pipe 403 is connected to the port on the filter 602. During the inspection, the engine oil in the oil outlet pipe 403 can flow into the filter 602. At this time, the filter 602 can separate the oil and water in the engine oil. After the separation, the engine oil flows into the cooling module 601 through the connecting pipe 603. At the same time, the cooling water in the water outlet pipe 303 also flows into the cooling module 601, so that the cooling water and the engine oil can perform heat exchange inside the cooling module 601. After the heat exchange is completed, the engine oil flows again into the heating box 201 through the oil inlet pipe 404, and the cooling water flows again into the cooling tower 302 through the water inlet pipe 304.

[0055] Further, for the temperature measurement assembly 7, the temperature sensor 7 includes a T-shaped mounting tube 701, and the T-shaped mounting tube 701 is arranged on the water outlet pipe 303, the water inlet pipe 304, the oil outlet pipe 403 and the oil inlet pipe 404. The inner wall of the detection box 1 is fixedly mounted with a fixing frame 702 corresponding to the T-shaped mounting tube 701, and one end of the T-shaped mounting tube 701 is fixedly connected to a storage box 703. The inner wall bottom of the storage box 703 is provided with a conical groove 704, and the inner part of the conical groove 704 is movable. A conical block 705 is movably connected, a mounting column 706 is fixedly connected to one side of the conical block 705, a temperature sensor 707 is fixedly installed on one end of the mounting column 706, and the temperature sensor 707 is located inside the T-shaped mounting tube 701. A mounting block 708 is fixedly connected to the other side of the conical block 705. A sealing groove 709 is provided at the bottom of the inner wall of the storage box 703, and a sealing frame 710 is movably connected to the inside of the sealing groove 709, and the sealing frame 710 is fixedly connected to the mounting block 708.

[0056] The temperature sensors 707 provided on the water outlet pipe 303, the water inlet pipe 304, the oil outlet pipe 403 and the oil inlet pipe 404 can measure the temperature of the engine oil and the cooling water, and analyze the heat exchange efficiency of the cooling module 601 through the temperature difference between the front and the back. When installing the temperature sensor 707, the temperature sensor 707 is directly installed on the outside of the detection box 1 at one end of the mounting column 706, and then the mounting column 706 is moved to the inside of the storage box 703. At this time, the mounting column 706 can be directly moved to the inside of the T-shaped mounting tube 701 through the tapered groove 704, and the tapered block 705 is moved to the inside of the tapered groove 704, and the sealing frame 710 is directly moved to the inside of the sealing groove 709. In summary, the temperature sensor 707 is mainly moved to the inside of the T-shaped mounting tube 701 by plugging, so that there is no need to reserve too much space to facilitate the installation of the temperature sensor 707, so that the water outlet pipe 303, the water inlet pipe 304, the oil outlet pipe 403 and the oil inlet pipe 404 can be arranged relatively compactly; at the same time, under the double sealing of the tapered block 705, the tapered groove 704, the sealing groove 709 and the sealing frame 710, after the installation of the temperature sensor 707 is completed, the overall sealing of the T-shaped mounting tube 701 can be guaranteed. The fixing frame 702 can fix the T-shaped mounting tube 701 , and this arrangement prevents the T-shaped mounting tube 701 from moving at will. This arrangement facilitates the subsequent replacement of the temperature sensor 707 .

[0057] Furthermore, for the above-mentioned mounting block 708, a fixing hole 711 is opened on the top of the mounting block 708, and the fixing hole 711 passes through the storage box 703. The fixing hole 711 is movably connected to a fixing rod 712 inside. The top of the storage box 703 is fixedly connected to a mounting tube 713 corresponding to the fixing rod 712. The mounting tube 713 is movably connected to a connecting plate 714 inside. The fixing rod 712 is fixedly connected to the connecting plate 714. A spring 715 is fixedly connected between the top of the connecting plate 714 and the inner wall of the mounting tube 713. The top end of the fixing rod 712 passes through the mounting tube 713 and is fixedly connected to a pull plate 716. The other side of the mounting block 708 is fixedly connected to a T-shaped pull plate 717, and one side of the T-shaped pull plate 717 is fixedly connected to a socket 718.

[0058] When replacing the temperature sensor 707, the fixing rod 712 is pulled upward by the pull plate 716, and the fixing rod 712 squeezes the spring 715 upward through the connecting plate 714, so that the fixing rod 712 can be moved out from the inside of the fixing hole 711 on the mounting block 708, and then the T-shaped pull plate 717 is pulled outward, so that the mounting block 708 can be moved out from the inside of the storage box 703. At the same time, the temperature sensor 707 is moved out from the inside of the T-shaped mounting tube 701 driven by the mounting block 708, and then the temperature sensor 707 is disassembled and replaced outside the detection box 1. The above arrangement makes it more convenient to move the temperature sensor 707 out from the inside of the T-shaped mounting tube 701. At the same time, when the fixing rod 712 fixes the mounting block 708 through the fixing hole 711, the spring 715 can press the fixing rod 712 downward through the connecting plate 714, so that the fixing rod 712 will not move out from the inside of the fixing hole 711 at will. This setting ensures the stability of the temperature sensor 707 when working inside the T-shaped mounting tube 701.

[0059] Furthermore, for the above-mentioned concentration detection component 8, the concentration detection component 8 includes a measuring box 801, and the measuring box 801 is arranged on the outer surface of the oil inlet pipe 404, and a capacitive moisture sensor 802 is arranged inside the measuring box 801.

[0060] When the oil flows out from the cooling module 601, the oil can flow through the measuring box 801 under the guidance of the oil inlet pipe 404. At this time, the capacitive moisture sensor 802 can measure the moisture contained in the oil flowing inside the measuring box 801. Since the capacitive moisture sensor 802 has a fast response speed, it can detect the moisture change in the oil in real time. In addition, its structure is relatively simple and its volume is small, so it is easy to install in the oil circulation system.

[0061] Furthermore, for the above-mentioned detection box 1, a controller 9 is fixedly installed on the inner wall of the detection box 1, and the controller 9 is electrically connected to the heating plate 202, the temperature sensor 707 and the capacitive moisture sensor 802. A display screen 10 is provided on the front side of the detection box 1 corresponding to the heating plate 202, the temperature sensor 707 and the capacitive moisture sensor 802.

[0062] The socket 718 is connected to the controller 9 through a wire, and the socket 718 is electrically connected to the temperature sensor 707. This arrangement allows the plug end of the wire to be moved out of the socket 718 before the temperature sensor 707 is disassembled when the socket 718 is moved out from the inside of the T-shaped mounting tube 701. At the same time, with the assistance of the controller 9, the data detected by the temperature sensors 707 and the capacitive moisture sensor 802 can be displayed on the corresponding display screen 10, so that the operator can better analyze the oil-water separation performance of the filter 602 and the heat exchange efficiency of the cooling module 601 through the displayed data. At the same time, the heating plate 202 can be controlled by the display screen 10 corresponding to the heating plate 202, so that the heating plate 202 can heat the engine oil to different temperatures.

[0063] Through the above technical scheme, 1. The engine oil is heated by the heating component 2, and the temperature of the engine oil after absorbing heat under different operating conditions of the motor is simulated. At the same time, the engine oil and cooling water can be continuously flowed inside the component to be tested 6 through the cooling circulation component 3 and the oil circulation component 4. At this time, several temperature measuring components 7 can detect the temperature of the engine oil and cooling water flowing into and out of the component to be tested 6, and the concentration detection component 8 can measure the concentration of the engine oil. In summary, it is only necessary to heat the engine oil to different temperatures through the heating component 2 to detect the engine running under different operating conditions. 1. The oil-water separation performance and heat exchange efficiency of the filter and the oil cooling module are tested under the condition of , so that the data of the tested components are more accurate; 2. The fixing rod 712 is pulled upward by the pull plate 716, and then the mounting block 708 is moved to the inside of the storage box 703. At this time, the temperature sensor 707 can be moved to the inside of the T-shaped mounting tube 701. At the same time, the conical block 705, the conical groove 704, the sealing groove 709 and the sealing frame 710 can cooperate to double-seal the storage box 703. Then, the pull plate 716 is loosened, so that the spring 715 passes through the connecting plate 7 14 pushes the fixing rod 712 downward, and the fixing rod 712 can be fixed through the fixing hole 711 on the mounting block 708. This arrangement makes it easier to replace the temperature sensor, and the overall stability and sealing of the temperature sensor 707 can be guaranteed when it is working; 3. The temperature sensor 707 can be moved to the inside of the T-shaped mounting tube 701 by plugging. In addition, the entire installation process only requires pulling the pull plate 716 and the T-shaped pull plate 717 to move the temperature sensor 707 out of the T-shaped mounting tube 701. Therefore, there is no need to reserve too much space to facilitate the installation of the temperature sensor 707. This arrangement allows the water outlet pipe 303, the water inlet pipe 304, the oil outlet pipe 403 and the oil inlet pipe 404 to be arranged relatively compactly as a whole, so that the path required for the oil and cooling water to flow during circulation is shorter, thereby preventing the oil and cooling water from losing too much temperature during circulation, so that the accuracy of the temperature sensors 707 when measuring the temperature of the oil and cooling water can be guaranteed, and the accuracy of detecting the heat exchange efficiency of the cooling module 601 can be further improved.

At the same time, the oil pump 401 extracts the oil in the heating box 201 to the inside of the flow filter 602 through the extraction pipe 402 and the oil outlet pipe 403. At this time, the temperature sensor 707 on the oil outlet pipe 403 measures the temperature of the oil. After the filter 602 separates the oil from the water in the oil, the oil flows into the inside of the cooling module 601 under the guidance of the connecting pipe 603.

[0067] After the oil and the cooling water complete the heat exchange inside the cooling module 601, the cooling water flows into the cooling tower 302 again through the water inlet pipe 304, and the temperature sensor 707 on the water inlet pipe 304 measures the cooling water temperature at this time;

[0068] The oil in the cooling module 601 flows into the measuring box 801 under the guidance of the oil inlet pipe 404, and the capacitive moisture sensor 802 measures the moisture in the oil flowing in the measuring box 801.

[0069] After the engine oil flows out from the measuring box 801, it returns to the inside of the heating box 201 under the guidance of the oil inlet pipe 404, and the temperature sensor 707 on the oil inlet pipe 404 measures the temperature of the engine oil at this time;

[0070] The data detected during the entire cycle of the engine oil is presented on the display screen 10 , and the oil-water separation performance of the filter and the heat exchange efficiency of the cooling module are analyzed through the data on the display screen 10 .

[0071] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
