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;
