[0022] The present invention will now be described in detail.

[0023] like Figure 1 As shown:

[0024] A multifunctional testing device for oil testing in an oil filter, used in conjunction with an oil tank 14, includes an oil inlet pipe 1 connected to the oil outlet of the oil tank 14, an oil pump 4 connected to the oil inlet pipe 1, a filter 9 connected to the oil pump 4 via a pipe 15, an oil outlet pipe 13 connected to the filter 9 and the oil inlet of the oil tank 14 respectively, and a testing pipeline 10 connected at one end to the oil inlet pipe 1 and at the other end to the oil outlet pipe 13; the testing pipeline 10 is connected to the pipe 15 via a pipe 7.

[0025] Specifically, the connection point between the oil inlet pipe 1 and the oil tank 14 is located at the bottom of the oil tank 14; the connection point between the oil outlet pipe 13 and the oil tank 14 is located at the top of the oil tank 14.

[0026] When testing unfiltered oil, pipeline 7 is opened, and at the same time, testing pipeline 10 is not connected to oil outlet pipeline 13; oil pump 4 delivers oil from oil tank 14 to pipeline 15.

[0027] A small portion of the oil entering pipe 15 enters the testing pipe 10 through pipe 7, enabling the testing of particle size and water content in the unfiltered oil (filter 9). After testing, the oil is then transported back to pipe 15. The majority of the oil passes through pipe 15 and then enters filter 9 for filtration. The filtered oil is then transported to the oil tank 14 through the oil outlet pipe 13. A small portion of the oil entering pipe 7 through pipe 15 will be directly tested without filtration, thus enabling the testing of the unfiltered oil in the oil tank 14.

[0028] When testing the filtered oil, pipeline 7 is closed, and testing pipeline 10 is connected to oil outlet pipeline 13; a small portion of the filtered oil enters testing pipeline 10 for particle size and water content testing; most of the filtered oil enters oil tank 14 through oil outlet pipeline 13; when the particle size is found to be within the required range, oil pump 4 stops working.

[0029] During the testing process, an early warning is issued when the water content in the oil is found to be substandard.

[0030] Compared with existing technologies, this invention can effectively improve detection efficiency, avoid the uncontrollability of manual sampling, provide more accurate data, and stop operation once the oil particle size meets the requirements, thus saving energy.

[0031] In some possible implementations, in order to effectively detect the particle size of oil products, the detection pipeline 10 includes a detection pipe with one end connected to the oil inlet pipe 1 and the other end connected to the oil outlet pipe 13, and a particle size sensor 6 installed on the detection pipe for detecting oil particles; the particle size sensor 6 is located between the connection point of the detection pipe and the oil inlet pipe 1 and the connection point of the detection pipe and the pipeline 7.

[0032] In order to effectively detect the water content, the detection pipeline 10 includes a micro water detection sensor 5 installed on the detection pipeline. The micro water detection sensor 5 is located between the connection point of the detection pipeline and the oil inlet pipe 1 and the connection point of the detection pipeline and the pipeline 7.

[0033] The micro-water detection sensor 5 and the particle size sensor 6 are arranged sequentially along the flow direction of the oil in the detection pipeline.

[0034] A small portion of the oil entering pipeline 15 via oil pump 4 will enter the detection pipeline via pipeline 7. The particle size sensor 6 on the detection pipeline will detect the particle size of this portion of oil. Subsequently, this portion of oil will be tested for water content by micro-water detection sensor 5. After the test is completed, this portion of oil will re-enter pipeline 15 under the action of oil pump 4.

[0035] During the cyclic filtration process, particle size sensor 6 and micro-moisture detection sensor 5 can perform real-time detection of the oil after each filtration; before the initial filtration, particle size sensor 6 and micro-moisture detection sensor 5 can detect the unfiltered oil; once the oil passes the filtration test, the entire device will stop working.

[0036] In some possible implementations, in order to effectively test the connection between the detection pipeline 10 and the oil outlet pipe 13, a second control valve 101 is provided on the detection pipeline, the second control valve 101 being located between the connection point of the detection pipeline and the pipeline 7 and the connection point of the detection pipeline and the oil outlet pipe 13.

[0037] In some possible implementations, in order to effectively realize the opening and closing of the detection pipeline 10 and the pipe 15 through the pipeline 7, a first control valve 71 is provided on the pipeline 7; the first control valve 71 is used to realize the connection between the detection pipeline 10 and the pipe 15.

[0038] Specifically, when testing unfiltered oil, the first control valve 71 is opened and the second control valve 101 is closed;

[0039] When testing the filtered oil, the second control valve 101 opens and the first control valve 71 closes.

[0040] In some possible implementations, an oil inlet solenoid valve 2 and an oil flow switch 3 are sequentially arranged on the oil inlet pipe 1 along the oil flow direction; the oil flow switch 3 is located at the connection point between the detection pipe and the oil inlet pipe 1 and between the oil inlet solenoid valve 2.

[0041] In some possible implementations, an oil outlet valve 11 and an oil outlet solenoid valve 12 are sequentially arranged on the oil outlet pipe 13 along the oil flow direction; the oil outlet solenoid valve 12 is located between the connection point of the detection pipeline 10 and the oil outlet pipe 13 and the oil outlet valve 11.

[0042] In some possible implementations, the filter 9 is a precision filter 9; a pressure gauge 8 is provided on top of the precision filter 9 to monitor its internal pressure.

[0043] In some possible implementations, a control cabinet is also included, which is connected to the micro-water detection sensor 5, the particle size sensor 6, the oil flow switch 3, the oil inlet solenoid valve 2, the oil outlet solenoid valve 12, the oil pump 4, the first control valve 71, and the second control valve 101, respectively.

[0044] The control cabinet enables automated control of this device. When the particle size of the filtered oil meets the requirements, the control cabinet can control the oil pump 4 to stop working.

[0045] Specifically, during use, the control cabinet periodically opens the inlet solenoid valve 2, the outlet solenoid valve 12, and the first control valve 71, closes the second control valve 101, and starts the oil pump 4. When the oil flow switch 3 detects oil flow, the control cabinet controls the oil pump 4 to continue running. The micro-water detection sensor 5 and the particle size sensor 6 transmit the oil quality index data to the control cabinet, thus realizing the detection of unfiltered oil.

[0046] After multiple filtration cycles, the second control valve 101 opens and the first control valve 71 closes to test the filtered oil. When the particle size of the filtered oil is found to be within acceptable limits, the control cabinet shuts down the oil pump 4. If the water content in the oil is unacceptable, the alarm module issues an alarm.

[0047] Furthermore, the control cabinet is equipped with an external alarm. When the moisture content does not meet the requirements, the control cabinet can activate the alarm to sound an alarm.

[0048] Furthermore, filter 9 is a precision filter, and pressure gauge 8 is connected to the control cabinet. When the pressure inside filter 9 does not meet the requirements, the control cabinet controls the oil pump 4 to stop working.

[0049] In this utility model, the micro water detection sensor 5, particle size sensor 6, oil flow switch 3, oil inlet solenoid valve 2, oil outlet solenoid valve 12, oil pump 4, first control valve 71, second control valve 101, and filter 9 are all existing technologies. The improvement of this utility model does not lie in its internal structure, and will not be described in detail here.

[0050] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
