The method of testing the rigor of the spiral duct machine
The test method of light leakage detection is to see the leakage from one end of the duct to the other, while observing the leakage situation in the appearance of the duct, when the voltage is not higher than 36v in the wind pipe and the power is above 36v, the power is more than 100w with a protective shield.
When a leak is observed in the appearance of the duct, there is a leak and the leaking area of the duct should be repaired. Leaks such as in the air pipe bite seam, rivet hole, flip four corners can be coated sealant or take other sealing measures;
The medium pressure system spiral duct machine should be after the leakage detection, the system leakage volume of sampling, high-pressure system spiral duct machine should be all air leakage test. The system measures the leakage amount value, should meet the design and specification requirements.
