[Summary Description] Explosion-proof light refers to a lamp used in dangerous places where combustible gas and dust exist, and can prevent the arc, spark and high temperature that may be generated inside the lamp from igniting the combustible gas and dust in the surrounding environment, so as to meet the requirements of explosion protection.

Explosion-proof light refers to a lamp used in dangerous places where flammable gas and dust exist, and can prevent the arc, spark and high temperature that may be generated inside the lamp from igniting the flammable gas and dust in the surrounding environment, so as to meet the requirements of explosion-proof. The explosion-proof light cannot be separated from the transparent part, and the transparent part is a very low-strength part in the shell part. Therefore, the reliability of the installation of the transparent part directly affects the safety performance of the explosion-proof light. Let's follow the editor of Explosion proof counter balance forklift to see how it is installed!

1. It is directly sealed in the shell and forms a whole with the shell. This method is simple, practical and widely used. The sealing material should be temperature-resistant and oil-resistant rubber parts, or use epoxy resin and other adhesives to seal the transparent parts in the shell and press tightly.
2. With or without a liner, directly fasten the transparent part in the shell. When the gasket is not used, the flatness of the joint surface of the transparent part is required to be very high. Generally, it is suitable for small flat glass and the glass joints are ground flat at the same time, otherwise the glass is unevenly stressed and easily broken.
3. It is sealed or glued on a frame, and the frame is fastened in the shell, so that the transparent part can be replaced as a whole. This structure is rarely used in lamps. In some large-scale equipment that requires frequent replacement of transparent parts, the transparent part and the frame are replaced as an integral part.
4. The sealing of the transparent part and the frame can refer to the type of 1. In terms of structure, the force (generated by internal explosion) of the transparent part should be transmitted directly to the metal shell as far as possible. It is not appropriate to pass the pressure plate and or screw of the transparent part to the metal shell. At the same time, after the transparent part is installed Can not be stressed, so as to ensure the reliable combination of the transparent part and the shell.
The above is the introduction by the editor of Explosion proof counter balance forklift about the installation method of the explosion-proof light with transparent parts. You can learn more about it.
