Most of the flue gas types continuously monitored online by explosion-proof analysis houses are flammable and toxic hazardous gases. Once an explosion occurs, the consequences would be unimaginable. Especially when the analysis house operates under long-term full load, on-site operation and maintenance must be properly carried out.。

How to carry out on-site operation and maintenance of flue gas online monitoring explosion-proof analysis houses??

2、RecommendationsRemainOperateMaintenanceFile案。From the installation, commissioning, operation, and maintenance of the explosion-proof analysis house to the downgrade of explosion-proof rating, scrapping, and replacement, including all types of explosion-proof electrical equipment inside the house, detailed records shall be made and filed.。

3. On-site operation and maintenance personnel must establish inspection, maintenance, and repair systems for explosion-proof electrical equipment, as well as explosion-proof safety education, technical training, and assessment systems.。

2、DailyOperateMaintenance

2. Check the gas circuit pipelines to keep them unobstructed and leak-free, check the gas source pressure of the gas supply equipment, with the normal compressed air value between 0.2MPa and 0.8MPa.。

3. The analysis house shall not be subject to external force damage during operation, and there shall be no tilting or component friction phenomena.。The sound should be normal, and the vibration value should not exceed specified limits.。

4. Check the integrity of explosion-proof electrical equipment in each system inside the explosion-proof analysis house, such as explosion-proof air conditioners, explosion-proof gas detectors, explosion-proof audible and visual alarm lights, explosion-proof distribution boxes, explosion-proof lighting fixtures, etc.。

6. Check whether the house body has cracks or mechanical deformation phenomena that impair explosion-proof performance.。Cable entry devices should be reliably sealed.。Unused cable entry holes shall be sealed with steel plates with a thickness of no less than 2mm.。The transparent plates of observation windows should be intact and free of cracks.。

8. The various protection, interlocking, detection, alarm, and grounding devices of the explosion-proof analysis house shall be complete and intact.。

9. Check whether the explosion-proof lighting fixtures maintain the integrity of their explosion-proof structure and protective covers as required.。Check that the surface temperature of the lighting fixtures does not exceed the value specified in the product documentation.。

10. The grounding wires of explosion-proof electrical equipment shall be firmly connected, with no loose grounding terminals, no obvious corrosion, no breakage, and no fracture in the outer steel tape of armored cables.。

11. When the explosion-proof audible and visual alarm light alarms, on-site operation and maintenance personnel must promptly troubleshoot the fault. If troubleshooting is not timely or no one handles it for a long time, when the pressure value of the explosion-proof analysis house falls below 50Pa, the power-off interlocking protection will be activated.。

Relatively speaking, the on-site operation and maintenance of the flue gas online monitoring explosion-proof analyzer cabinet is still relatively simple. Technicians trained in explosion-proof technology can handle daily operation and maintenance, and issues that cannot be resolved can be addressed by contacting the explosion-proof analyzer cabinet manufacturer. Henan Hualong Electric performs very well in after-sales service.
