Whether the explosion-proof monitoring equipment is compatible with the regional classification level, whether it is suitable for the surrounding gas classification protection; whether the temperature level of the explosion-proof monitoring and power control equipment is suitable for the self-ignition point of the surrounding flammable gas; the qualified explosion-proof electrical explosion-proof equipment should be marked: manufacturer name, certification Unit, certification number, explosion-proof construction for gas groups, temperature class.
1. Whether the selection of explosion-proof monitoring equipment is consistent with the regional classification level, whether it is suitable for surrounding gas classification protection; whether the temperature level of explosion-proof monitoring and power control equipment is suitable for the spontaneous ignition point of surrounding flammable gas; qualified explosion-proof electrical explosion-proof equipment should be marked: manufacturer name , certification unit, certification number, explosion-proof structure for gas groups, temperature class.
2. Whether the line marking information of the explosion-proof camera equipment is complete, whether the camera housing cover and function are damaged, and whether the monitoring equipment protective cover and the sealing gasket can be completely sealed.
3. Whether the screw or cable interface equipment (direct or indirect) and the spacing component are correct, the screws or joints of the pipeline are not loose, the joints are clean and free of damage, and the monitoring cable joints must be explosion-proof joints and have an explosion-proof certification mark.
4. If there is a gasket on the pressure-proof and explosion-proof equipment joint, it should be confirmed whether it is purely waterproof.
5. On-site signal transmission The condition of the gasket of the electrical equipment casing of the explosion-proof box is normal.
6, explosion-proof monitoring equipment sealing gasket should be silica gel type is not easy to aging, not easy to change the material.
7. Explosion-proof filler should be used at the explosion-proof joint of the explosion-proof box and the camera to block the electrical spark inside the equipment.
8. Whether the installation of monitoring equipment and explosion-proof box is properly grounded according to requirements.
9. Whether the pressure explosion-proof box has a safety lock or must be opened with special tools.
The monitoring explosion-proof control box used in the mining area is different from the general equipment wiring equipment. From the connection and distribution of cables to the front-end fiber or network transmission equipment, from the control receiver, the main power switch to the leakage circuit breaker and the arrester or surge absorption, it is associated with the explosion-proof control box. In addition, these devices are prone to gas and gas explosion, so the material and thickness of the explosion-proof junction box is particularly important. In general, it is recommended to choose 304/316 stainless steel as the material; size and size requirements, all equipment must be put into the analog wiring, and the joint transition is smooth, it can be used, otherwise the terminal equipment with too small space is used because of the cost. Box, but it will cause the device temperature to be too high.
FURD Ride On Laser Screed:
-Used high accuracy laser device, close loop control technology and precision integrated hydraulic system, and microcomputer automatic control.
