Datetime: 2021-04-01 17:04:42
The LED
explosion-proof lamp is a kind of explosion-proof lamp. Its basic principle is
the same as that of the explosion-proof lamp, except that the light source is
an LED light source, which means to better avoid igniting the surrounding
combustible compounds such as combustible vapors in the natural environment and
combustible smoke. Various special countermeasure lamps adopted for natural
environment and coal-bed methane gas.
2. What are the
advantages of LED explosion-proof lights?
LED belongs to
the solid cold light source. It has the advantages of high photoelectric
conversion efficiency, low calorific value, low power consumption, safe working
standard voltage, low voltage, long service life and other advantages, and it
is energy-saving.
3. Natural
environment where LED explosion-proof lights can be used
LED
explosion-proof service platform lights are suitable for fixed lighting
fixtures for petrochemical equipment, crude oil service platforms, gas
stations, gasoline pump rooms, transfer stations, oil and gas fields and other
flammable sites.
4. What are the
markings and protection levels of LED explosion-proof lights?
Explosion-proof
mark: Exd II BT6, Exd II CT4, Gb
Waterproof
grade: IP66, IP67.
5. Frequently
Asked Questions
5.1. Remove dust
and stains on the shell of explosion-proof lamps on time to improve the special
effects and heat dissipation characteristics of the lamps. The cleaning method
can be based on the safety protection work capacity of the lamp housing, using
water spray (marked on the lamp above the shade) or wipe with a damp cloth.
When cleaning by sprinkling water, the switch power supply should be
disconnected, and it is forbidden to clean the plastic shell (fully transparent
part) of the lamp with a damp cloth to avoid electrostatic induction.
5.2. Check whether the fully transparent
parts are affected by the impact of dirt, whether the safety protection net is
loose, welded, eroded, etc. If there is, it should be stopped and repaired and
replaced immediately.
5.3. If the light
source is damaged, the lights should be turned off immediately to prevent the
electronic ballast and other electrical components from being abnormal for a
long time because the light source cannot be started.
5.4. If there is
water in the lamp cavity of the lamp used in a humid and cold natural
environment, it should be eliminated immediately, and the sealing member should
be removed and replaced to ensure the safety and protection characteristics of
the shell.
5.5. When opening
the lamp cover, according to the provisions of the warning sign, turn off the
power supply and open the meter cover.
5.6. After
opening the meter cover, check whether the flameproof fusion surface is intact,
whether the rubber product is hard or sticky, whether the sheath of the
transmission line and cable is yellowed and charred, whether the insulation
layer and electrical components are tangible Change and scorch marks. If such a
problem is found, it should be repaired and replaced immediately.
5.7. Before closing
the cover, use a damp cloth (not too wet) to gently wipe the light return and
transparent parts of the lamp to enhance the special effect of the lamp. The
flameproof fusion surface should be coated with a thin layer of 204-1 replacement
type rust inhibitor. When closing the cover, pay attention to whether the
sealing ring has a sealing effect on the original part.
5.8. Part of the
airtightness of the lamp cannot be disassembled and opened frequently.
6. Maintenance
Before
installing the LED explosion-proof lamp, check from the factory nameplate and
product manual: explosion-proof type, type, grade, grade; waterproof grade of
the shell; installation method and standard parts requirements for
installation, etc. The installation of the explosion-proof lamp should ensure
that it is firmly fixed, and the anchor bolts should not be dismantled and
replaced at will. Spring washers should be available. The anti-fouling and
moisture-proof sealing ring should be placed in the original state when
installing. At the three-phase five-wire cable, the cable and the gasket should
cooperate with each other, the cross section of the cable should be circular,
and the surface of the sheath does not need to have defects such as convex and
concave. Unnecessary three-phase five-wire ports must be plugged according to
the explosion-proof type.
