ZSB127-ZWater level alarm mine water level alarm & nbsp; & nbsp;
The working principle of the water level alarm:
The water level alarm is in the “E”(drain) mode, when the water level exceeds the set value(High water level “H”), The normally open contact of the internal relay of the main engine is closed, and the water pump switch is controlled to start to drain water. When the water level is lower than the set value(Low water level “L”), The internal relay is disconnected, and the water pump stops draining.
In “F”(water injection) mode, when the water level is lower than the set value(Low water level “L”)When the internal relay contact is closed, the water pump switch is controlled to start, and the water injection starts; when the water level exceeds the set value(High water level “H”)When the time, the internal relay contact is disconnected and the water injection is stopped.
In any mode, if the water level exceeds the set limit value(High alarm value “b” and low alarm value“d”)When, the display emits “
Beep ” alarm sound accompanied by flashing yellow light.
The water level alarm is composed of ZSB127-Z mine explosion-proof and intrinsically safe water level alarm device host, ZSB12-X mine intrinsically safe water level alarm device display, GUH1 mine water level sensorAnd ZKC-12F remote control transmitter.
