explosion proof light manufacturer

explosion proof lamp installation.

explosion proof lamp before installation to check from the nameplate and product instructions: explosion-proof type, category, level, group; shell protection level; installation and installation with fasteners requirements. explosion proof lamp installation to ensure that the fixed secure, fastening bolts shall not be arbitrarily replaced, spring washers should be complete. Dustproof, waterproof with the installation of the seal should be placed as is. Cable inlet, the cable and sealing gasket to closely match the cable section should be round, and the sheath surface should not be bumpy and other defects. Excess inlet, shall be blocked according to the type of explosion-proof, and will tighten the compression nut to make the inlet sealed.

The maintenance and repair of the proof lamp.

1、Daily maintenance

In the daily maintenance maintenance, the following points need to be noted.

(1) explosion proof lamp, lampshade should be able to automatically cut off the power supply before opening. But because of the complexity of setting up interlocking devices, it is not easy to achieve, so most of the lamps and lanterns only in the shell of the obvious place to set "strictly prohibited to open with electricity" and other words of the warning sign. And because the surface temperature of the bulb is still very high after the power failure, such as immediately open the lampshade NSC9720A railroad tunnel light, there is still the risk of ignition of explosive gas mixtures (mainly refers to the explosion-proof structure), so incandescent lamps, high-pressure mercury lamps, high-pressure sodium lamps, these light sources with high surface temperature of the bulb, and can quickly open the cover of the lamps to pay attention to this point. The author's unit uses more CeY-1 explosion-proof fluorescent lamps have an interlocking mechanism to open the cover and power off, which provides convenience and safety for maintenance work. Because fluorescent lamps are cold light source lamps, there is no surface high temperature, and the cover can be opened immediately after power failure.

(2), in the replacement of light bulbs (tubes), explosion proof lamp of the explosion-proof joint surface should be properly protected from damage; after cleaning the explosion-proof surface should be coated with phosphate paste or 204-1 antirust oil, is strictly prohibited to paint other paints; explosion-proof surface shall not have a rust layer, if there is a lighter rust, after cleaning should not be pockmarked phenomenon. Used for dustproof, waterproof with the seal must be intact, which is very important for safety-enhancing lamps and lanterns. If the seal is seriously damaged, it should be replaced with the same specification and material, and if necessary, the whole lamp should be replaced. Inspection and repair should pay attention to whether the lampshade is intact, if there is a rupture to immediately replace.

2、Regular maintenance and repair

(1), maintenance and repair personnel need to be trained by the post, to understand the performance of lamps and lanterns, clear use requirements. Maintenance personnel must have professional knowledge and be familiar with the structure of lamps and lanterns products.

(2), regularly eliminate the dust and dirt on the housing of the explosion proof lamp, improve the luminous efficiency and heat dissipation performance of the lamps. Cleaning method can be based on the protective capacity of the lamp shell, using water spray (lamps and lanterns on the sign above Yin) or wipe with a wet cloth. When spraying water cleaning, should cut off the power supply, forbidden to use dry cloth scrubbing lamps and lanterns plastic shell (transparent parts) to prevent static electricity.

(3 ), check the lamp plastic shell (transparent parts) has no serious discoloration, such as serious discoloration, indicating that the plastic has been aging. Check whether the transparent parts have been impacted by foreign objects traces, protection network has not loosened, desoldering, corrosion, etc.. If there is, should stop using, timely repair and replacement.

(4 ), light source damage should be promptly shut down, notify the replacement, so as not to start the light source and ballast and other electrical components in an abnormal state for a long time.

(5), the humid environment used in the lamp cavity of lamps and lanterns such as water should be removed in a timely manner, replace the sealing parts to ensure shell protection performance.
Explosion-proof lamps and lanterns how to install and repair.

(6), open the lampshade, should be required by the warning sign, open the cover after the power is cut.

(7), after opening the cover should incidentally check whether the combination of explosion-proof surface is intact, whether the rubber seal is hardened or sticky, whether the wire insulation layer is green and carbonized, whether the insulating parts and electrical components are deformed and scorch marks. If these problems are found, should be promptly repaired and replaced.

(8), after repair and replacement of light sources, parts and electrical components of the model, specifications, size, performance and repair and replacement of light sources, parts and electrical components before the exact same.

(9), close the cover before the application of wet cloth (not excessively wet) light wipe lamps and lanterns back to the light and transparent parts, in order to improve the luminous efficiency of the lamps and lanterns. In the explosion-proof combined surface should be thinly coated with a layer of 204-1 replacement type rust-proof oil, close the cover should pay attention to whether the seal in the original position to play a sealing role.

(10), explosion proof lamp sealed parts should not often disassemble and open.
