Explosion-proof monitoring equipment selection and regional classification level is in line with, is suitable for the surrounding environment gas classification protection; explosion-proof monitoring and power control equipment selection temperature level is suitable for the surrounding ignition gas spontaneous combustion point; qualified explosion-proof electrical explosion-proof equipment should be marked: manufacturer name, certification Unit, certification number, explosion-proof structure applicable gas group, temperature rating.
1. Whether the explosion-proof monitoring equipment is selected and classified according to the regional classification, whether it is suitable for the protection of the ambient gas classification; whether the temperature level of the explosion-proof monitoring and power control equipment is suitable for the spontaneous combustion of the surrounding flammable gas; qualified explosion-proof electrical explosion-proof equipment should be marked: manufacturer name , certification unit, certification number, explosion-proof structure applicable gas group, temperature rating.
2. Whether the line marking data of the explosion-proof camera equipment is complete, whether the camera housing shield and the function are damaged, and whether the monitoring equipment protection cover and the sealing gasket can be completely sealed.
3, screw, cable interface equipment (direct or indirect) and spacing components of the model is correct, the pipeline screws or joints can not be loose, the junction is clean and no damage, monitoring cable joints must be explosion-proof joints and explosion-proof certification mark.
4, pressure explosion-proof equipment interface if there is a gasket should confirm whether it is purely waterproof.
5. Field signal transmission Explosion-proof box The gasket of the electrical equipment shell is normal. Is the screw locked to the position?
6, explosion-proof monitoring equipment, gaskets should be silicone type is not easy to aging, difficult to change the material.
7. Explosion-proof fillers should be used on explosion-proof joints of explosion-proof boxes and cameras to prevent electrical sparks inside the equipment.
8. Whether the monitoring equipment and explosion-proof box are installed according to the requirements and properly grounded.
9, pressure explosion-proof box has a security lock, or must use special tools to open.
