What kind of lighting is used in heavy equipment in the coal mining industry?

Heavy equipment in coal mines is divided into two categories: movable and stationary.

1. Stationary heavy equipment is generally not randomly assembled with lighting, and the lamps and lanterns equipped for safety or improvement of the working environment are mostly laid on the top of the roadway, and these lamps and lanterns are generally installed in the bottom of the well, ** (mining area) substation, alley, transportation equipment control chamber and other places, there is no fixed model, when choosing according to the requirements in addition to explosion-proof is a hard provision, it is recommended to consider the service life, lighting effect, energy saving and beauty requirements, the production of this type of lamps and lanterns There are many manufacturers, and it is best to choose the old manufacturer when purchasing.

2. I have not seen the movable heavy equipment coal mining face; In addition to explosion-proof, there are no hard regulations for the installation of electric locomotives, comprehensive excavators and rake loaders for transportation, the power is generally 60-250W, the voltage is 127V, I have used 80W, it is already very bright, and I have heard that the Shenhua Roadheader has used a 500W searchlight, I personally think that the power is too large and not very good, and the dizziness and light that are too strong when the workers face the searchlight are also disadvantages.

Generally, it is an explosion-proof lamp installed, which is 127V. It's like a searchlight.

LED lights, don't bother with these lights. There's no need.

Let's see for myself, I don't know if it's too professional.

The 6v battery strap is not much.

Shearers, comprehensive excavators, continuous mining machines, crushers, belt conveyors, scrapers, ventilators, compressors, water pumps, transformers, flameproof switches, mobile substations, mobile compressors, hoists, dispatching winches, column return machines, hydraulic supports, emulsification pumps, spray pumps, grouting machines, boilers, etc.

Do you mean underground mining, mainly the equipment required for underground lifting and transportation, ventilation, drainage, power supply, air pressure, coal mining and tunneling.

There are many types of equipment used in coal mines, including open-pit mining equipment and underground mining equipment, and open-pit mining equipment includes perforating machines, loaders, engineering transport vehicles, stripping equipment, and large conveyors; Underground mining equipment includes lifting equipment, transportation equipment and mining equipment, etc.

Qufu Huaqiang's mine flameproof LED lighting Biwangdong features: Lingbo has a long life and can be replaced without bulbs. The illuminance is not affected by the voltage drop of the battery, and the illuminance remains unchanged from the beginning of the battery discharge to the end of the discharge.

The energy-saving battery has a limit of energy, and is widely used in emergency use such as underground rescue cabins in coal mines.

I recommend Trinity.

Reliable quality. Perfect after-sales service.

It should be a diode, and an ordinary light-emitting diode 20mA is enough.

There is no value in repairing, and one can be directly matched outside.

Is it a diode, the current is very small, are you going to wire it or is it broken?

LED is a low-voltage constant current drive, the voltage of a single lamp bead is the voltage, the transformer you get is to convert the high voltage of 220V into the low voltage voltage required by the LED lamp and the specified constant current, the sound heard causes the LED transformer to burn out, of course the LED lamp can not be lit, if the damage causes the output voltage to be too high, it will lead to the burning of the LED lamp beads, so that the whole lamp is broken, if you destroy the things yourself only in the power supply, the power supply does not give the lamp beads high voltage and high current, Then this LED light can still be used for a new power supply. However, the power supply of different LED lights is different, please do not disassemble and assemble it at will.

Puxiangyuan Optoelectronics specializes in the production of LED lighting fixtures.

There are many metering equipment used in coal mines, and the key is to see what it is used for! Loading load limit measurement, you can use loader scales, weighbridges, loading and metering using loader scales, but which weighing method is used to choose in combination with the actual situation.
