防爆电气设备例行检查项目

危险环境下防爆电气设备必不可少, 但随着时间的推移缺乏全面的维护可能会变成风险, 否定其预防目的.

1. 审查一般检查程序.

2. 评估接线盒, 进线设备, 保护密封盒, 成角度的连接器以保证密封性, 安全安装, and adherence to explosion-proof standards.

3. Evaluate the level of corrosion on motors, 电气设备, instrument panels, and the equipment itself, ensuring screws are securely fastened and interlock mechanisms function properly.

4. For oil-immersed explosion-proof equipment, verify that oil level indicators, drainage systems, and gas venting structures remain clear and leak-free, with an installation incline not exceeding 5 度.

5. Ensure that the internal air pressure of pressurized explosion-proof equipment meets or exceeds the values indicated on the equipment label, and that the pressure cut-off alarm system is responsive.

6. Check cables for looseness, vibration-induced damage, and signs of corrosion.

7. Beyond explosion-proof specifications, maintain the equipment in optimum condition in accordance with general electrical equipment standards.
