ZLS-95KL Filter Material Comprehensive Performance Test Bench
Introduction: The ZLS-95KL filter material comprehensive performance test bench is developed according to the standard GB 2626-2019 "Respiratory protective equipment self-priming filter anti-particulate respirator" 6.3 filtration efficiency test method. According to the standard GB2626-2019 "Respiratory protective equipment self-priming filter anti-particulate respirator" (salt, oily aerosol) GB/T32610-2016 "Technical Specification for Daily Protective Masks" (salt, oily aerosol) GB 19083-2010 "Technical Requirements for Medical Protective Masks" (salt aerosol) The test bench is a fully automatic instrument, controlled by a microcomputer to run the following operations, and all working parameters are automatically fed back, controlled and read: air volume, resistance, and efficiency. In a measurement cycle, the number of sampled particles and the resistance of the sample are measured. The test bed provides an aerosol generator, an oily aerosol generator, which can use DOP, paraffin oil, DEHS, corn oil and other oily substances; or a salt aerosol generator, usually 2% NaCl solution. Technical parameter: Aerosol type: sodium chloride, DOP, paraffin oil, etc. Aerosol concentration: the concentration of NaCl particles is (12-20) mg/m3, the median diameter is (0.075 ± 0.020) um, the geometric deviation of the particle size distribution does not exceed 1.86, and the mass median diameter is 0.26 um Particle detector adopts particle counter: 0.3-10um Differential pressure test range: 0-1000Pa, 2.5-level accuracy Air volume test range: 20-100L/min Efficiency measurement range: filtration efficiency (0-99.999)%, resolution 0.003% Automated operation and data management: special software, computer control processing Power supply: 230VAC 50Hz 1.5KW Compressed air requirement: 0.6MPa air flow rate is 200L/min
