The leaking substance with a certain pressure is filled inside the test piece. If there is a leak hole in the test piece using vacuum leak detection equipment for air conditioner, the leaking substance will leak out from the leak hole. The leak from the leak hole is detected outside the test piece by a certain method or instrument. Showing the leaked substance, so as to determine the existence, location and size of the leak.
Vacuum Leak Detection Equipment For Air Conditioner cooperation:0-5.5MPa high pressure nitrogean is charged into the testing product, when the pressure is stable, it starts to hold the pressure. After pressure holding time is finished, the equipment will automatically judge the product is qualified or not. Reference value: leakage less than 0.001MPa for pressure holding 10 seconds.
