How to scientifically maintain the explosion-proof camera？
China's electrical equipment explosion-proof requirements in the petroleum, chemical, pharmaceutical, marine, aerospace, metallurgy, scientific research and military industry and other fields have strict regulations. With the accelerated development of explosion-proof industrial monitoring products, the video surveillance system has also become a standard in many industries.
Explosion-proof camera housing and all parts are made of stainless steel, using advanced design and processing technology for welding, to maintain the integrity and strength of the cylinder, with high stability. In the explosion-proof shell, the camera movement is installed in the drawer plate, the drawer plate and the back cover of the protective cover using insulation connection, so it will not form a system of electrical interference, and easy to install. The front window glass of the explosion-proof camera adopts special explosion-proof glass, whose large diameter can obtain a large viewing angle, suitable for all kinds of places that need to be monitored under the mine.
How to scientifically maintain the explosion-proof camera
Tips one, Handling of Explosion-Proof Camera Connections
① Explosion-proof camera instrument inlet, must be sealed with rubber seals, prohibit the use of filling sealing mud, asbestos rope and other methods instead;
② It is prohibited to fill the cavity with any substances that may affect the explosion-proof performance;
③ It is forbidden to discard the sealing ring at the inlet and the matching compression nut for the sake of easy connection;
④ Prohibit multi-stranded single conductor merged into the inlet through a single hole elastic sealing ring, rubber sealing ring on the oil should be scrubbed clean to avoid aging deterioration.
Tip two, it is strictly prohibited to casually change the structure of the explosion-proof camera meter.
Explosion-proof camera is strictly prohibited in the use of arbitrary changes in the structure of the explosion-proof camera, parts and equipment, the internal line. Fastening bolts shall not be arbitrarily switched or missing, and its excess inlet and outlet of the elastic gasket and metal gasket must maintain the factory sealing status, and should tighten the compression nut to make the inlet seal.
Tip three, explosion-proof camera circuit maintenance points
In the explosion hazardous places prohibit the closing of the switch” warning sign. Inspection and maintenance, such as the explosion-proof camera removed to a safe area, the site of the equipment power cable head should be made explosion-proof treatment, and prohibited power..
Tip four, explosion-proof camera instrument routine maintenance is prohibited to open the shell
Daily operation and maintenance checks, should try to avoid opening the shell of the explosion-proof camera, must be opened should first cut off the power supply. If the explosion-proof shell open, should properly protect the surface of the explosion-proof, shall not be damaged, the surface of the explosion-proof in maintenance should be placed upward, shall not directly touch the ground, the surface of the field should be coated with phosphate paste or 204 antirust oil after cleaning.
