Leakage Volume Tester

Model:LQ-90

Basic Principles

Under ideal conditions, when gas is injected into a sealed container while maintaining a constant pressure inside, the flow rate of the injected gas equals the leakage rate of the sealed container.

Testing Principle

Connect the exhaust outlet of the leak tester's fan to the test duct using a flexible hose.Fans, fire dampers, ducted air conditioning and ventilation systemsAbove, the air duct section in question, except for the hoses connecting to the testing device and the pressure gauge tube that extends from above, should have all other interfaces sealed. As the air leak detection instrument is activated and the fan speed is gradually increased, air is injected into the air duct through the hoses, and the pressure within the air duct will also gradually rise. When the air duct reaches the required test pressure,AutomaticAdjustWholeThe fan speed of the tester is adjusted to maintain a constant pressure within the duct, at which point the air volume measured at the fan inlet is the leakage volume of the tested duct at that pressure.
