Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of filter element filtration testing, specifically to an oil-water separation efficiency testing device that can simulate the generation of returned parts. Background Technology
[0002] Existing oil-water separator filter elements are tested in a completely new state, resulting in oil-water separation performance obtained during testing that is far higher than the actual separation performance during actual oil-water separation. This leads to a discrepancy between theoretical and actual data. How to resolve this discrepancy is a critical technical challenge that needs to be addressed during the testing process of oil-water separator filter elements. Utility Model Content
[0003] To address the aforementioned issues, this invention provides an oil-water separation efficiency testing device that can simulate the generation of returned parts. Before testing, the oil-water separation filter element is made to have a certain degree of contamination, thereby obtaining oil-water separation performance close to reality, making the test practical.
[0004] An oil-water separation efficiency testing device capable of simulating the generation of returned parts, characterized in that it comprises: Ash injection system; The cleaning filter element is equipped with pressure sensors at its input and output positions. System filter element; Main hydraulic cylinder; And water containers; The output end of the ash injection system is connected to the input end of the cleaning filter element. The oil output end of the cleaning filter element is connected to the input end of the system filter element. The oil output end of the system filter element is connected to the input end of the main oil cylinder. The output end of the main oil cylinder and the output end of the water container are mixed and then connected to the input end of the cleaning filter element. The input end of the cleaning filter element is provided with an upstream sample sampling port, and the oil output end of the cleaning filter element is provided with a downstream sample sampling port.
[0005] Its further features are: The output end of the ash injection system sends the ash-containing material into the input main pipe of the cleaning filter element through the first output pipeline, the first metering pump, and the first one-way valve. The output end of the main cylinder sends a fixed amount of cleaning oil to the first input end of the oil-water mixing manifold through the second output pipeline, the second metering pump, and the second check valve. The output end of the water container sends water to the second input end of the oil-water mixing manifold through the third output pipeline, the third metering pump, and the third check valve. The body of the oil-water mixing manifold mixes the oil and water and sends it to the input main pipe of the cleaning filter element through the output end.
[0006] With the structure of this utility model, the testing device has two working modes: return component configuration mode and return component testing mode. In the return component configuration mode, the ash injection system continuously injects ash-containing oil into the cleaning filter element. At the same time, the oil filtered by the cleaning filter element is filtered again by the system filter element to obtain clean oil, which is then injected into the main oil cylinder until the pressure sensors at the input and output positions of the cleaning filter element reach the set termination pressure difference. At this time, the cleaning filter element becomes a return component. In the return component testing mode, the ash injection system stops operating, and the main oil cylinder and water container output and pass the mixed oil-water solution into the cleaning filter element that has become a return component. The water content of the oil is tested by sampling through the upstream and downstream sampling ports of the cleaning filter element, and then the oil-water separation efficiency is calculated. Before the test, the oil-water separation filter element is made to have a certain degree of contamination, so as to obtain oil-water separation performance close to reality, making the test practical. Attached Figure Description
[0007] Figure 1 This is a simplified structural diagram of the present invention; The names corresponding to the serial numbers in the diagram are as follows: The system includes: ash injection system 10, first output pipeline 11, first metering pump 12, first check valve 13, cleaning filter element 20, inlet pressure sensor 201, outlet pressure sensor 202, upstream sample sampling port 21, downstream sample sampling port 22, input main pipe 23, system filter element 30, main oil cylinder 40, second output pipeline 41, second metering pump 42, second check valve 43, water container 50, third output pipeline 51, third metering pump 52, third check valve 53, and oil-water mixing manifold 60. Detailed Implementation
[0008] A test device for simulating the oil-water separation efficiency generated by returned parts, see Figure 1 It includes an ash injection system 10, a cleaning filter element 20, a system filter element 30, a main oil cylinder 40, and a water container 50; The cleaning filter element 20 is equipped with an inlet pressure sensor 201 at the input position and an outlet pressure sensor 202 at the oil output position. The output end of the ash injection system 10 is connected to the input end of the cleaning filter element 20. The oil output end of the cleaning filter element 20 is connected to the input end of the system filter element 30. The oil output end of the system filter element 30 is connected to the input end of the main oil cylinder 40. The output end of the main oil cylinder 40 and the output end of the water container 50 are mixed and then connected to the input end of the cleaning filter element 20. The input end of the cleaning filter element 20 is provided with an upstream sample sampling port 21, and the oil output end of the cleaning filter element 20 is provided with a downstream sample sampling port 22.
[0009] In specific implementation, the output end of the ash injection system 10 sends the ash-containing material into the input main pipe 23 of the cleaning filter element 20 through the first output pipe 11, the first metering pump 12, and the first one-way valve 13; The output end of the main oil cylinder 40 sends a fixed amount of cleaning oil into the first input end of the oil-water mixing manifold 60 through the second output pipe 41, the second metering pump 42, and the second check valve 43. The output end of the water container 50 sends water into the second input end of the oil-water mixing manifold 60 through the third output pipe 51, the third metering pump 52, and the third check valve 53. The body of the oil-water mixing manifold 60 mixes the oil and water and sends it into the input main pipe 23 of the cleaning filter element 20 through the output end.
[0010] The testing device has two operating modes: return component configuration mode and return component testing mode. In return component configuration mode, the pressure difference between the inlet and outlet pressure sensors is preset. When the actual pressure difference exceeds the preset value, the cleaning filter element is made into a return component. This return component is equivalent to the actual working state of the cleaning filter element after it has reached a certain mileage. The first ash injection system continuously injects ash-containing oil into the cleaning filter element through the first metering pump. At the same time, the oil filtered by the cleaning filter element is filtered again by the system filter element to obtain clean oil, which is then injected into the main oil cylinder until the cleaning process continues. When the pressure sensors at the input and output positions of the filter element reach the set termination pressure difference, the clean filter element becomes a return piece. In the return piece test mode, the ash injection system stops operating, and the main oil cylinder and water container are metered by pumps to output and pass the mixed oil-water solution into the clean filter element that has become a return piece. The water content of the oil is tested by taking samples from the upstream and downstream sampling ports of the clean filter element, and then the oil-water separation efficiency is calculated. Before the test, the oil-water separation filter element is made to have a certain degree of contamination, so as to obtain oil-water separation performance close to reality, making the test practical.
