Mine explosion-proof and intrinsically safe drinking fountains

Factory direct proof intrinsically safe drinking fountains latest price of ore with an automatic heating water dispenser Shanxi mine intrinsically safe drinking fountains

A, YJR-5/127 fountains Adaptation:

For a coal mine gas and coal dust explosion hazard areas. Automatic heating water use, greatly improving the quality of life of underground workers.

Second, the implementation of standards

Q / HHJD16-2008YJR-5/127 mine explosion-proof and intrinsically safe drinking fountains;

GB3836.1-2000 explosive gas atmospheres Electrical Equipment Part 1: General requirements;

GB3836.2-2000 explosive gas atmospheres - electrical equipment - Part 2: flameproof 'd';

GB3836.4-2000 explosive gas environment with electrical equipment Part 4: Intrinsic safety 'i';

MT / T661-1997 coal mine electrical equipment general technical conditions;

Third, the mine explosion-proof and intrinsically safe drinking fountains working conditions

Turnout should be able to work under the following conditions:

1) Ambient temperature: -5 ℃ ~ 40 ℃, pressure of 0.8 ~ 1.1 * 105Pa;

2) Altitude: low-voltage electrical equipment 2000m;

3) The monthly average ambient air relative humidity less than 95% (25 ℃);

4) use to have gas and coal mine explosion hazard hole interior;

5) without damage to the insulation of gas or steam environment;

6) Pollution levels for three;

7) mounted no significant vibration and shock place, the installation location should not exceed 2 degrees inclination.

Fourth, the main technical features

2, explosion-proof type: Mine explosion-proof and intrinsically safe; proof mark: Exd [ib] I

3, Power supply: Three-phase AC (50HZ) 127V; fluctuation range of 75% to 110%;

4, drinking fountains have proof the main chamber, wiring chamber, a control circuit, electric heaters, hot water chamber, intrinsically safe lights, switches and buzzer composition. Housing made of stainless steel welded steel plate welded by the explosion chamber .

5, the product of the main circuit for the explosion part, lights, switches, buzzer intrinsically safe circuits.

6, cable dispenser should be 3 * 4mm2 + 1 * 2.5mm2 explosion-proof cable, the maximum cable length of 15m, distributed capacitance ≤0.1uF / km, distributed inductance ≤1 mH / km.

Fifth, the mine explosion-proof and intrinsically safe drinking fountains main performance

1, power supply voltage: Three-phase AC (50HZ) 127V allowed fluctuation range of 75% to 110% of the nominal value.

2, rated heating power 1.8KW, rated current: 8.1A.

3, a heating boil 5L;

4, automatic heating kettle: When the water temperature rose to 90 ℃ thermostat (switch) KT2 off; stop heating; when the temperature dropped to 80 ℃ thermostat is turned on; reheating; hot water was maintained at 80 ℃ ~ 90 ℃;

5, overload and short circuit protection: When the load current ≥12A time; the main circuit fuse disconnect; cut off the power;

6, leakage protection: Leakage Operation Resistance 3kΩ + 20%; leakage blocking resistance 7kΩ + 20%;

7, water heating over-temperature protection: When the water temperature rose to 90 ℃ thermostat KT1 disconnected; stop heating; into the insulation; if KT2 constantly open; when the water temperature rose to 99 ℃ when the thermostat KT1 disconnected; stop heating;
