Explosion-proof product debugging:
In order to prevent the destruction of the explosion-proof structure and performance of the explosion-proof camera, the professional inspection and maintenance of the equipment shall be performed by the end-user professional electric technicians trained in the explosion-proof technology.
1. The entrance of the explosion-proof camera must be sealed with rubber seals. It is forbidden to replace it with other methods such as filling sealant and asbestos rope; it is forbidden to fill any substance in the cavity. Explosion-proof performance is forbidden; For the convenience of connection, the sealing ring at the inlet and its matching pressing nut are forbidden to be discarded; multiple single-stranded wires are forbidden to merge and enter the inlet port through the single-hole elastic sealing ring. The oil on the rubber seal should be scrubbed to avoid aging deterioration;
Second, it is prohibited to accidentally modify the explosion-proof camera's structure, components and equipment inside the line. The fastening bolts shall not be exchanged or missing, and the elastic gaskets and metal gaskets of the extra inlet and outlet ports must be kept sealed at the factory, and the compression nut should be tightened so that the inlet port is sealed;
Third, in the ** dangerous places are prohibited electrified maintenance of electrical equipment and lines, the prohibition of transmission, power outage. And a warning sign “Someone working, no closing†should be hung on the offsite. During inspection and maintenance, if the explosion-proof camera is removed to a safe area, the equipment power cable end of the site shall be well-prepared for explosion protection and must not be energized.
Fourth, daily operation and maintenance inspections, should try to avoid opening the explosion-proof camera shell, must first open the power should be cut off. If the explosion-proof enclosure is opened, the explosion-proof surface shall be properly protected and shall not be damaged. During the inspection, the explosion-proof surface shall be placed upwards, and shall not be in direct contact with the ground. After the scene is cleaned, it shall be coated with phosphated plaster or 204 antirust oil;
V. All explosion-proof cameras shall establish equipment files, install, test, operate, and repair equipment, and decompress and decompose the equipment until it is decommissioned. Various technical data of different periods should be collected, archived, and numbered one by one on the device.
Explosion-proof product maintenance knowledge:
1. This camera is a surveillance product that is used in special environments. The power must be turned off before opening the back cover.
Second, should try to avoid open the back cover in a high humidity environment, or because of its good sealing, cavity humidity can not be eliminated for a long time, will cause image blur;
Third, the long-term exposure of the camera in a hostile environment will be stained with dust, please wipe regularly to ensure the transparency of the mirror;
4. Periodically inspect the elasticity of the sealing ring in the cable entry device. If it loses its elasticity due to aging, it must be replaced with parts of the same specification (dimensions and hardness), and no other materials may be used for replacement;
5. Regularly check all the bolts of the camera for looseness and whether there are any defects in the parts;
6. Remove dirt, dust and moisture from the camera case regularly;
7. Regularly check whether the camera's movement is good and the work is normal.
Explosion-proof camera is an explosion-proof monitoring product, which is a cross product of the explosion-proof industry and the monitoring industry. Because the conventional camera product cannot be used in a high-risk flammable and explosive site, it needs to have an explosion-proof function and has related certificates issued by national authorities. The product can be called an explosion-proof camera.
