What are the conventional measurement methods for the air leakage rate of dust collectors?

The air leakage rate of dust collectors is an indicator for evaluating the tightness of the dust collector structure. It refers to the percentage of air leakage under the operating conditions of the dust collector equipment to the inlet air volume. It should be pointed out that the air leakage rate varies due to the different negative pressure levels in the dust collector. The air leakage rates given by most domestic manufacturers are data measured under arbitrary conditions, so they lack comparability. For this reason, the conditions for calibrating the air leakage rate are met. The bag dust collector standard stipulates: The air leakage rate measured when the static pressure of the clean air box is maintained at 2000Pa shall prevail. Other dust collectors do not have this provision.

The methods for measuring the air leakage rate of dust collectors include air volume balance method, carbon balance method, etc.

Generally speaking, it is controlled within 10%. The normal air leakage rate is 5%. The air leakage rate will affect the dust collection effect.
