Maintenance of exhaust gas analyzer:

1. Sensor: replace once every 1-2 years

2. The pretreatment detection system is an on-line real-time analysis system with complex working environment and much outdoor interference. In order to make the instrument operate continuously, accurately and safely, periodic maintenance and calibration must be carried out

3. Analytical instrument: it is recommended to calibrate zero point and target point in 3-6 months

4. Filter: it is suggested that the enterprise should replace it once from January to March

5. Forward blowing pump: it is recommended to replace it once every 6 months

6. Back blowing function: it is suggested that enterprises should carry out back blowing for 15 minutes in 15-30 days

Operation of exhaust gas analyzer:

1. Modification of Mn number

2. Modification of time data

3. Real time concentration display / gas name / real time curve / alarm prompt

4. Query of historical data

5. Control the working state or flow rate of forward and reverse blowing system

6. Modification of alarm value

7. Calibration and calibration of concentration value

At present, the pretreatment detection system of Tianjin exhaust gas analyzer adopts embedded software, which integrates high-performance microprocessor. The embedded software realizes signal processing, data calculation, real-time control, man-machine interface operation, LCD display, alarm, networking and other functions.
