Gas electric slip ring sealing (gas leakage) inspection
Tightness (leakage) inspection is the most important part of the gas+electric slip ring. Put the gas electric slip ring into the water at 5-10 cm for 10 seconds, turn on the 1Mpa air pressure, and keep rotating the gas electric slip ring back and forth for 20 seconds, and observe whether there are bubbles emerging during the whole process.
