Explosion-proof luminaires are the most demanding and most widely used explosion-proof electrical products in petrochemical projects. Today, Beijing Huarong Xiaobian mainly introduces the installation measures of the CU-TR explosion-proof lamp transparent cover.
The CU-TR explosion-proof lamp is inseparable from the transparent cover, and the transparent part is the lowest strength part of the outer casing part. Therefore, whether the transparent part is installed reliably or not directly affects the safety performance of the explosion-proof lamp. Here are three common CU-TR explosion-proof lamp transparent cover installation methods:
1. Directly sealed in the CU-TR explosion-proof lamp housing, forming a whole with the explosion-proof housing. This method is simple and practical, and is widely used. The sealing material should be made of a temperature-resistant or oil-resistant rubber or an adhesive such as an epoxy resin to seal the transparent member in the outer casing and press it tightly.
2. Fasten the transparent cover in the explosion-proof lamp housing with or without a gasket. When the liner is not used, the flatness of the transparent cover is required to be high. Generally, it is suitable for small flat glass and the glass joint must be smoothed, otherwise the glass is unevenly stressed and easily broken.
Third, sealed or glued to a frame, the frame is fastened in the explosion-proof lamp housing. This allows the transparent cover to be replaced as a whole, which is rarely used in CU-TR explosion-proof luminaires. Replace the transparent part and frame as a single part on large equipment that requires frequent replacement of the transparent part.
The above are the three common CU-TR explosion-proof lamp transparent parts installation methods. The sealing of the transparent parts and the frame should be as far as possible to transmit the force received by the transparent cover to the metal casing. At the same time, the transparent member can not be stressed after installation, so as to ensure the transparent cover and the outer casing are reliably combined.
