Explosion-proof cast light use method introduction

April 09, 2023

Explosion-proof floodlights are suitable for large-scale cast light lighting in various indoor and outdoor operations such as flammable and explosive places, oil fields, offshore oil platforms and ships, metallurgy, petrochemicals, construction sites, and large-scale equipment. So, how to use explosion-proof flood light? Here's how to use explosion-proof floodlights.
Explosion-proof cast light use method introduction

According to the actual needs of the work site to determine the lighting installation location and method, and then according to the distance from the lamp to the power contact to prepare the corresponding length of Φ8 ~ Φ14mm three-core cable.

Open the end cap of ballast, loosen the pressing nut of the ballast cable inlet, and then lead the lamp cable and power cable through the compression nut to the internal terminal of the ballast, connect and fix, and tighten separately. Cables tighten nuts and tighten ballast end caps.

According to the determined installation location and method, the lamps and ballasts are installed, and then the other end of the input cable of the ballast can be connected to the 220V power supply according to the requirements of explosion-proof.

Loosen the screw at the bottom of the lamp holder, adjust the lighting position by rotating 360° around the lamp holder; loosen the screws on both sides of the lamp holder, adjust the lighting angle of the lamp up and down according to the lighting requirements, and then fasten the screws.

When replacing the lamp, use a suitable screwdriver or other tool to insert the front cover into the holes on the two front side of the front cover, remove the bad lamp, and replace the new one.

The above is an introduction to the use of explosion-proof floodlights. I hope to be helpful to everyone.

Sodium Hydrosulfide

Colorless needle-like crystals. Easily deliquescent. At the melting point, hydrogen sulfide is liberated. Easily soluble in water and alcohol. The aqueous solution is strongly alkaline. It reacts with acid to generate hydrogen sulfide. Bitter taste.

The chemical compound with the formula NaHS.Sodium Hydrosulfide is applied in the leather industry, waste water treatment, soil remediation, the mining industry and pulp paper and amongst others.
Sodium hydrosulfide have 2 kinds of appearance,70%min yellow flake and 30% yellowsih liquid.
We have different specs which depends on Fe content,we have 10ppm,15ppm,20ppm and 30ppm.Different Fe content,the quality is different.
