How to open an explosion proof light fixture?

Introduction: explosion proof lamps as a petrochemical, mining and other hazardous environments, the core of the lighting equipment, the correct way to turn on the equipment directly affects the life and operational safety. This article provides professional operating procedures and precautions to help you avoid risk and improve efficiency.

First, explosion proof light fixture before turning on the safety preparations

Environmental assessment and risk screening

Before operation, you need to confirm that the surrounding environment without flammable and explosive gas leakage (such as methane, dust), and check whether the explosion proof lamp shell is intact without cracks. If working in wet or corrosive places, it is necessary to additionally verify whether the IP protection level of the lamps and lanterns is up to standard.

Power off and equipment status confirmation

Turn off the power and wait for 5 minutes to ensure that the luminaire is completely cooled down. Use a voltage tester to verify that there is no residual current in the wiring to avoid sparks that could cause safety hazards.

Preparation of tools and protective equipment

Wear anti-static gloves and goggles, and prepare explosion proof certified screwdrivers (such as copper alloy), to avoid sparks caused by friction of ordinary tools.

Second, step-by-step analysis of the correct method of opening the explosion proof light fixture

Step 1: unlock the explosion proof light sealing structure

Most explosion proof lamps use threaded or snap seal design. Counterclockwise rotation of the lamp cover, you need to apply uniform force to avoid thread jamming. If resistance is encountered, use anti-rust lubricant to assist, do not force prying.

Step 2: Check the Integrity of Internal Components

After opening, quickly check the lamp beads, ballasts and wiring ports for oxidation or looseness. If the seals are found to be aged or broken, the original parts (e.g. silicone seals) need to be replaced immediately to ensure explosion proof performance.

Step 3: Safe power-on and function test

After restoring the power supply, observe whether the lamp start is delayed or flickering. Use infrared thermometer to detect the surface temperature to ensure that it does not exceed the T6 level (≤85℃) labeled on the equipment.

Third, the operation of contraindications and common problems to deal with

Prohibited behavior:

Force open the cover without power off;

Use non-explosion proof tools to modify the structure of the lamps and lanterns;

Neglecting the ambient temperature and humidity conditions (e.g. -20 ℃ below the need to preheat).

Failure emergency program:

Lamps and lanterns can not start: Priority to check whether the line is compatible with the voltage (such as 220V/380V), to rule out driver failure;

Abnormal heat: immediately disconnect the power and contact the manufacturer to test the cooling module.

Fourth, to extend the life of explosion proof light fixture maintenance recommendations

Regular maintenance cycle:

Every 3 months to clean up the lamps and lanterns surface oil (use neutral cleaner), every 6 months to detect the sealing performance (air tightness tester).

Parts replacement standard:

Seals are recommended to be replaced every 2 years, LED light source life before the expiration of the whole batch needs to be updated to avoid inconsistent color temperature.

Conclusion: professional operation to enhance the effectiveness of explosion proof lights

Mastering the standardized opening process and maintenance methods can minimize the risk of industrial accidents. For customized explosion proof lighting solutions or technical training, please consult AMASLY’s team of engineers for ATEX/IECEx compliant equipment support.
