1 Subject content and applicable questions
SY/T 6584--83
This standard specifies the test method and test result evaluation of the sealing test of petroleum exploration and development instruments (hereinafter referred to as "instruments"). This standard is applicable to the inspection of the sealing performance of instruments with a pressure resistance value below 1MPa. 2 Reference standards
GB2423.23 Basic environmental test procedures for electrical and electronic products·Test Q: Sealing. SY/T5203 General principles for basic environmental testing of petroleum exploration and development instruments. 3 Test methods:
3.1 Instrument container sealing (leakage) test
3.1.1 Instrument container sealing (leakage) test method 1: Use a pressurized instrument container to immerse in water to 3.1.1.1 Check all the sealing parts of the instrument to determine whether they are installed correctly. 3.1.1.2 The test device for this test is a liquid tank. The liquid tank should contain enough water to immerse the uppermost end of the instrument seal at a depth of 10mm below the liquid surface.
3.1.1.3 The water temperature should be maintained at 15C above the maximum ambient temperature specified for the instrument product or the temperature specified in the relevant product standards. 3.1.1.4 Inflate the instrument container so that the pressure inside the shell reaches the specified requirements. Select the pressure value according to the structure and material of the instrument container. The pressure value in the container is usually 1.5-~300kPa. 3.1.1.5 The test duration is 5 to 10 minutes when the instrument is immersed in water. 3.1.1.6 Usually at any time during the test duration, obvious continuous bubbles, two or more large bubbles or attached bubbles that gradually increase in size appear. If the above test failure criteria are met, the seal will be judged as failure. 3.1.2 Instrument container seal (leakage) test method 2: This is achieved by immersing the pressurized instrument container in a constant high overflow test liquid. 3.1.2.1 Check all sealing parts of the instrument to determine whether they are installed correctly. 3.1.2.2 The test equipment for this test is a liquid tank with heated and constant temperature test liquid. The liquid tank should contain enough test liquid. , so that the top of the instrument is submerged to a depth of 10m below the liquid surface. 3.1.2.3 First heat the test liquid and keep the test liquid constant at 90100℃, then immerse the instrument in the test liquid. 3.1.2.4 The test duration is 1~5min for the instrument to be immersed in the test liquid. 3.1.2.5 Usually, at any time during the test duration, obvious continuous bubbles, two or more large bubbles or attached bubbles with gradually increasing volume appear. It is judged that the seal has failed. 3.2 Receiver flooding test
3.2.1 Perform initial inspection on the instrument, that is, measure the electrical and mechanical properties of the instrument and inspect its appearance. All sealing parts should be checked to determine whether they are installed correctly. 3.2.2 Place the instrument in a pressurized water tank and apply the specified pressure, see the attached table. 3.2.3 The temperature of the instrument during the test should be higher than the room temperature, but should not be more than 10°G higher than the water temperature. The water temperature does not exceed 35C. 3.2.4 Use a 100~500V megohmmeter to measure the insulation resistance of the instrument.

Note: For the test of swamp (beach) geomagnetic detector, the instrument should be immersed in salt water with a concentration of 5%. For other instruments, it can be determined by their product standards. 3.2.5 When tested under the above conditions, the insulation resistance of the instrument shall not be less than 20M2, or shall be determined by the insulation resistance value specified in its product standard.
3.2.6 During the immersion period, the instrument shall be in a non-operating, power-off state, and its movable parts shall be in a static state. 4 Test results
4,1 The data recorded during the test shall be complete, accurate, and in accordance with the provisions of the instrument product standard. 4.2 If there are no other provisions in the relevant standards, the surface of the instrument shall be thoroughly dried by wiping or blowing with room temperature air. The instrument shall be subjected to final inspection, i.e., appearance inspection, electrical performance and mechanical property measurement. Additional remarks:
