LC201 Filter material efficiency detector
Description
LC201 Filter material efficiency detector
LC201 Filter material efficiency detector, suitable for testing 30%-99.999% grade filter material efficiency test, according to international standards to test the filter material. The design structure of the whole test bench is compact and light, and in the process of running and testing, only suitable power supply and compressed air (no water, no oil) need to be provided, which is suitable for use in laboratories, factories and other occasions.
Components of the filter test bench
1. Aerosol generator, salt aerosol and oil aerosol generator interchange
It is used for experiments that require high-concentration aerosols. Using aerosols can produce aerosols continuously and stably. Provide the test aerosol to the upstream of the filter material.
2. Aerosol photometer
It is used to simultaneously monitor the mass concentration of the upstream and downstream aerosols of the tested filter material, and obtain the particle filtration efficiency of the tested filter material.
3. Differential pressure sensor
Used to test the pressure difference (or resistance) of the tested filter material under a certain test flow.
4. Fixture
It is used to compress the tested filter material.
5. Imported air pump
It is used for the test flow through the filter material, the flow is stable, green and energy-saving, and low vibration and noise.
6. Control system
The circuit control and operation of the equipment, the calculation and data processing of the software, the stability judgment of the upstream concentration, the operation control, and the parameter setting.
Function description of filter test bench
A. Filter efficiency test and air flow resistance:
1. The whole test equipment adopts negative pressure system.
2. Air and aerosol enter through the test chamber and pass through the mask according to the standard flow rate.
3. Detect the upstream and downstream concentration by a photometer at the same time to calculate the filtration efficiency. The pressure difference between the upstream and downstream of the outlet cover is detected by a pressure difference meter.
4. Use the suction pump to reach the rated flow.
5. Generate standard aerosol substances through an aerosol generator.
6. PLC control system and man-machine interface processing system operation and calculation of efficiency resistance.
