Operation Instructions
System Startup:
- Verify power, air supply, and aerosol generator.
- Configure test parameters (flow rate, differential pressure, aerosol type).
Testing Process:
- Install filter media in dedicated test fixtures.
- Start the test; system automatically measures differential pressure, efficiency, and loading capacity.
Data Recording and Reporting:
- System generates test reports automatically and stores data for traceability and quality control.
Experimental Procedure
Preparation:
- Configure test parameters (target efficiency, flow rate).
- Install filter media in fixtures.
- Check all equipment and aerosol generator operation.
Testing:
- Automated measurement of differential pressure, dust loading, and separation efficiency.
- Data is recorded continuously.
Result Analysis:
- System generates a detailed report including efficiency, pressure drop, and loading capacity.
Maintenance Information
Periodically check aerosol generator and particle measuring instruments.
Ensure calibration of sensors for accurate measurements.
Clean system components to maintain test accuracy.
