Mechanical Industry Standards Service Network: http/AvwwJB.ac.cn6682 The air leakage rate of the dust collector is under normal filtering conditions (no dust cleaning test, the negative pressure in the clean air chamber of the dust collector is 2500Pa, when the negative pressure deviates, it is calculated according to the following formula:
E=50×e//p
Where: - air leakage rate, %:
e——measured air leakage rate, %
p—average negative pressure in the clean air chamber, Pa.bZxz.net
5.3 Inspection method
5.3.1 The dimensional accuracy grade of the tools used for geometric dimension inspection shall not be lower than Grade II, and the straightness inspection shall be carried out by the wire drawing method. 5.3.2 The sealing of the weld shall be inspected by kerosene penetration. The length of the weld to be inspected shall not be less than 50% of the total length of the weld, and all types of welds shall be included. 5.3.3 The paint film thickness shall be inspected by a paint film thickness gauge, and the paint film thickness inspection shall be carried out at no less than two points per square meter. 5.3.4 The paint film adhesion shall be in accordance with JB/T53134 The inspection is carried out in accordance with the provisions of the regulations. The adhesion inspection shall be carried out by preparing three samples according to the same rust removal level and painting process as the dust collector, and taking the same inspection results of two or more samples. 5.3.5 The valve air tightness inspection shall be carried out according to the method agreed upon by the supply and demand parties. 6 Inspection rules
