Main control box of mine automatic sprinkling dust device
1. Scope of application ZP127 mine automatic sprinkling dust device is mainly used for automatic sprinkling and dust reduction in coal mine roadway; it can provide automatic sprinkling and dust reduction for transportation roadway, belt conveyor transfer point and other places.
It is mainly used for automatic sprinkling and dust reduction at the transfer point of belt conveyor. In the touch mode, the host can realize the automatic spray function of touch. After touching the touch sensor, when the object touches the sensor, the device acts and starts spraying. After a certain time delay (the time is set by the user (20~1000 seconds)), the device stops sprinkling spray automatically.
2.Environmental conditions for use The device works reliably under the following conditions:
A. The ambient temperature is generally - 20 ºC ~ + 40 ºC;
B. Average relative humidity: < 96% RH (+ 25 ºC);
C. Atmospheric pressure: (80 ~ 110) kPa;
D. Generally, the ambient noise shall not be greater than 75db;
E. Where there is explosive gas mixture of methane and coal dust, but there is no corrosive gas damaging insulation;
F. No dripping or other liquid immersion;
G. In the environment without strong vibration and shock.
3.Main parameter A. Rated input voltage and frequency: AC 127 V, 50Hz;
B. Host size: (length × width × height): 336mm × 210mm × 90mm;
C. Host weight: 20kg;
D. Intrinsic safety parameters: Uo:12.4V Io:1A Co:22uF Lo:0.
