Shenhai Explosion-Proof
1. LED tawg-pov thawj teeb yuav tsum muaj accessories, thiab tsis-tawg-proof qhov chaw (xws li hlau, lampshade, hlws ris, li ntawd.) must not replace the light fixtures’ tivthaiv. Lub tsev ntawm teeb thiab switches yuav tsum nyob twj ywm. Hlau meshes yuav tsum pub dawb los ntawm deformation, lampshades tsis cracks, and the explosion-proof markings clearly visible.
2. The threaded connection between the lamp bracket, hloov, and junction boxes should engage at least five times. The processed threads should be smooth, Tiav, free of corrosion, and coated with electrophoretic composite grease or conductive anti-rust grease. The light bulb fastening bolts should be tightened, and switches secured to ensure they do not become loose, and washers should remain intact.
3. The installation location of the explosion-proof lights should be far from the release source, and should not be higher or lower than the pressure release outlets of various pipelines.
4. When installing explosion-proof lights, the nozzles near the light fixtures and on top of the pipelines must be sealed, as well as the nozzles inside the lamp heads.
5. The specific method for isolation and sealing is to wrap the external threads with fine cotton rope. The number of coils depends on the diameter of the wire and the pipe. They must be close to the inner diameter of the pipe. If there are multiple wires inside the pipe, they should be wound 1 mus rau 3 times before wrapping. The pipe joints should be sealed with asphalt.
6. Electrical connections must be tightly contacted and secured against loosening, such as using anti-loosening washers and locking nuts. To ensure the seal of the device, inlet isolation and sealing must be carried out. If the wires are not disconnected, use an explosion-proof plug to block the socket.
