YZBJ76014.2--88 Particle Extraction Performance Testing Method
According to the provisions of the national standard Technical Specifications for Industrial Safety Pollution Control Equipment YZBJ 76014.2-88 , various particle extraction performance tests are required for industrial powder exhausters In order to ensure that the equipment meets the requirements of regulatory standards, particle extraction performance testing must be conducted by engineering personnel.
The performance test of particle extractor shall be carried out according to the provisions of《Technical Specification for Industrial Safety Pollution Control Equipment YZBJ76014.2-88》. It mainly includes four aspects: determination of particle collection efficiency, determination of dust concentration, determination of filter material properties, measurement of leak resistance, etc.
The determination of the collection efficiency of the particle extractor is divided into oil filter efficiency test with sodium-containing oil filter as test agent and laboratory dust source as test dust. This test is used to verify the removal efficiency of dust. It is mainly used to verify the removal efficiency of dust particles and particles with a particle size greater than 5um.
The determination of dust concentration refers to the determination of the influence of dust concentration on the dust collection effect of the particle extractor. By changing the dust concentration of the test environment, it can be seen what kind of dust concentration can make the dust collector maintain a good dust collection effect.
The determination of filter material properties is to determine the characteristics of the filter material of the particle extractor, mainly to measure the impedance of the filter material, the permeability of the filter material and the durability of the filter material. It is mainly used to verify the usability of the filter material in the particle extractor.
Measurement of leakage resistance is to measure the leakage rate of the particle extractor. There are mainly two test methods, static leakage resistance test and dynamic leakage resistance test. The static leakage resistance test uses static pressure to measure the leakage rate of the particle extractor, while the dynamic leakage resistance test uses the flow of wind to measure the leakage rate of the particle extractor.
These 4 parts combined form the particle extraction performance test. The particle extraction performance test is mainly used to check and verify whether the airflow resistance of the particle extractor is up to standard, whether it has the capacity of dust collection, whether the sealing performance of the filter material is up to standard, and whether the leakage rate of the particle extractor is up to standard. This process can ensure that the particle extractor can operate in a safe and reliable manner, and lay a solid foundation for its normal operation and use.
