Referring to fig. 2 to fig. 3, the embodiment of the present invention describes a detection method of the anti-leakage detection system. The detection method of the leakage-proof detection system is realized by adopting the leakage-proof detection system. The detection method comprises the following steps:
s1 ambient pressure measurement: the pressure value P1 of the environment in which the test piece 6 is located is determined by the pressure testing assembly 2. Specifically, the door cover of the to-be-tested part 6 is opened, so that the to-be-tested part 6 is communicated with the outside, and the internal air pressure of the to-be-tested part 6 is consistent with the external air pressure; and then, a power switch of the leakage-proof detection system is turned on, so that the leakage-proof detection system is electrified to work, the pressure value P1 of the environment where the piece 6 to be tested is located is measured through the pressure testing component 2, and the value is transmitted to the main control component 4 to be stored and recorded. Here, the ambient pressure value P1 can be used as a standard air pressure value for the leak protection test.
S2 first pressure measurement: pumping the gas in the to-be-tested piece 6 through the gas pumping assembly 1 until the pressure value in the to-be-tested piece 6 reaches the target value range, and then stopping; then, waiting for a time T1, a pressure value P2 in the test piece 6 is measured by the pressure testing unit 2.
Specifically, when the ambient pressure value P1 is measured, the test piece 6 to be tested is closed and sealed. Then, the air pump 11 is used to pump out the air in the test piece 6 to be tested through the air pumping valve 12, the pressure testing assembly 2 can measure the pressure inside the test piece 6 to be tested in real time, when negative pressure is formed inside the test piece 6 to be tested, the state indicating assembly 3 sends out a first flashing signal at the moment, and the first flashing signal can be yellow color light, that is, a yellow indicating lamp flashes, which is not limited herein. When the pressure in the test piece 6 approaches the target value range with the continuous pumping of the air pump 11, the yellow indicator lamp flickers more and more slowly; when the pressure inside the test piece 6 reaches the target value range, the status indicating assembly 3 sends a long bright signal, which may be the yellow light, and is not limited herein, and the air pump 11 stops pumping air.
If the air extracting pump 11 extracts air more, and the pressure inside the to-be-tested part 6 is lower than the target value, at this time, the state indicating assembly 3 sends a second flashing signal, and the second flashing signal can be a mutual flashing signal formed by yellow light sent by a yellow indicating lamp and red light sent by a red indicating lamp, so as to remind an operator that the pressure inside the to-be-tested part 6 needs to be adjusted through the air release valve 13, so that the pressure inside the to-be-tested part 6 is within the target value range. Here, the light emitting color of the second blinking signal can be adjusted according to actual needs, and is not limited herein. The more the pressure inside the test piece 6 is lower than the target value, the faster the yellow indicator lamp and the red indicator lamp flash with each other. The long bright signal remains in the long bright state only when the internal pressure of the test piece 6 is within the target value range, and the air escape valve 13 is closed, followed by the next process.
In the actual operation process, the pressure in the test piece 6 to be tested can be accurately adjusted according to actual needs by repeatedly operating the air pump 11 and the air release valve 13 for many times so as to reach the target value range, and the adjustment is not limited herein.
S3 second pressure measurement: after the first pressure measurement step, the pressure value P3 in the test piece 6 is measured again by the pressure measurement unit 2 while continuing to wait for time T2.
Judgment and analysis of S4: calculating the air leakage rate through a formula (P3-P2)/T2, and comparing the air leakage rate with a set threshold value R; if the air leakage rate is smaller than the threshold value R, judging that the detection of the piece to be tested 6 is qualified; and if the air leakage rate is greater than the threshold value R, judging that the detection of the piece to be tested 6 is unqualified.
Specifically, the pressure testing assembly 2 transmits the measured pressure values P1, P2, P3 and the times T1, T2 to the main control assembly 4 in real time, and the main control assembly 4 can store and record the data and calculate the air leakage rate by the above formula. When the air leakage rate is greater than the threshold value R, the state indicating component 3 sends a third flashing signal at the moment, and the third flashing signal can be red color light, namely, a red indicating lamp flashes to prompt an operator that the leak-proof detection of the piece to be tested 6 is unqualified. Here, the light emitting color of the third blinking signal can be adjusted according to actual needs, and is not limited herein. When the air leakage rate is smaller than the threshold value R, the green indicating lamp flickers at the moment to prompt the operator that the leak-proof detection of the piece to be tested 6 is qualified.
Alternatively, when T2 is constant, it can be directly compared (P3-P2) with a preset value P to make a leak detection qualification judgment. If the differential pressure value (P3-P2) is smaller than the preset value P, the leak-proof detection of the test piece 6 is qualified; if the differential pressure value (P3-P2) is greater than the preset value P, the leak-proof detection of the test piece 6 is not qualified.
Optionally, after the leak-proof test of the test piece 6 to be tested after the test analysis in the step S4 is qualified, the steps S3 and S4 may be repeated to perform the second leak-proof test on the test piece 6 to be tested. And when the air leakage rate is larger than the threshold value R, the red indicator lamp flickers at the moment to prompt the operator that the leakage-proof detection of the piece to be tested 6 is unqualified. When the air leakage rate is less than threshold value R, the green pilot lamp scintillation this moment to the suggestion operating personnel awaits measuring the leak protection of 6 and detect qualified, main control module 4 can lock the result, under this lock-out condition, can not be because of the await measuring 6 in the use under water, the inside atmospheric pressure of the await measuring 6 changes because of the change of outside water pressure or temperature, thereby leads to the unqualified error message of leak protection performance, and then improves the accuracy nature of leak protection detection. This structure, only when the result of twice leak protection detection is all qualified, just can judge that the leak protection of waiting to test piece 6 detects for qualified to can effectively avoid the error operation that leak protection detected once and appears, and then can improve the precision. The total analysis time of the leak-proof detection system is T1+2T 2. The test shows that the time length of the embodiment is about 4 minutes, and compared with the traditional detection equipment, the detection time length can be greatly shortened. In other embodiments, the number of times of repeating steps S3 and S4 may also be adjusted according to actual needs, and is not limited herein.
Optionally, the to-be-tested piece 6 which is qualified after two times of detection is subjected to leak-proof test under the condition that the ambient pressure value is P1, and the leak-proof performance of the to-be-tested piece 6 can be tested under different ambient pressures by changing the ambient pressure value P1, so that the leak-proof situation of the to-be-tested piece 6 under different ambient pressures can be known, the to-be-tested piece 6 can be subjected to leak-proof test in detail, the accurate relationship between the leak-proof performance and the ambient pressure is provided, and the to-be-tested piece 6 can be conveniently used.
Alternatively, in the second pressure measurement process, pressure measurement may be repeatedly performed a plurality of times, and corresponding pressure values P4, P5 … P may be obtainedNThe air leakage rate L was obtained from (P3-P2)/T21(P4-P3)/T2 gave an air leakage rate L2And (P)N+1-PN) The air leakage rate L is obtained by T2N-1By analyzing L1 and L2 … LN-1Can accurately analyze the pressure condition in the test piece 6, thereby presuming whether the test piece 6 has air leakage or water leakageTo determine whether the piece to be tested 6 satisfies the leak-proof performance.
Compared with the prior art, the leak-proof detection system and the detection method provided by the embodiment of the utility model can measure the environmental pressure P1 through the pressure test component 2 before leak-proof detection is carried out on the test piece 6 to be tested, thus realizing the test of the waterproof performance of the test piece 6 to be tested under different pressure environments; the air extracting component 1 can extract air in the to-be-tested piece 6, so that the pressure value in the to-be-tested piece 6 reaches a target value range, the pressure value in the to-be-tested piece 6 at the moment is measured to be P2, after the time of T2, the pressure value in the to-be-tested piece 6 is measured to be P3 again through the pressure testing component 2, the air leakage rate is calculated through a formula (P3-P2)/T2, the air leakage rate is compared with a set threshold value R, and the waterproof performance of the to-be-tested piece 6 under the specific environmental pressure P1 can be judged quickly. The utility model discloses can set for different ambient pressure value P1 to test the waterproof performance of piece 6 under the different pressure value environment, extensive adaptability is good, and short when detecting, efficient.
In the prior art, the pressure difference value is determined by an absolute value test system, that is, the pressure value P2 of the first pressure measurement is directly compared with the pressure value P3 of the second pressure measurement, and since the pressure value P2 changes along with the geographical factors of the test and the like, the difference value between the pressure value P3 and the pressure value P2 changes, which may seriously affect the test target conditions and the accuracy of the test result. However, in the embodiment of the present application, the differential pressure value is determined by the relative value testing system, that is, the relative value is tested by the ratio of the difference between the pressure value P2 and the pressure value P3 to the time T2, so that the difference between the pressure value P2 and the pressure value P3 is not affected by the environment, and the stability, reliability and accuracy of the test result are improved.
Moreover, the comparison analysis by the differential pressure value requires waiting for a long test time and test period, which results in a long test time and inconvenience for rapid detection. However, the embodiment of the application performs comparative analysis through the air leakage rate, and can calculate whether the piece to be tested 6 has leakage or not and the trend of leakage in the shortest testing time, so that the testing time and the testing period can be greatly shortened, the leakage-proof performance of the piece to be tested 6 can be rapidly and accurately judged, and the testing efficiency and the testing precision are further improved.

It should be understood that, the sequence numbers of the steps in the above embodiments do not mean the execution sequence, and the execution sequence of the processes should be determined by the functions and the inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
