ZPS127 mine automatic sprinkler dust-reducing device is suitable for automatic sprinkler spray control of coal mine underground mining face, roadway, ventilation and purification water curtain and belt conveyor loading point. Spraying or sprinkling water can not only achieve dust and dust reduction, but also reduce the concentration of harmful gases, which will play an important role in effectively preventing pneumoconiosis and ensuring safe production of coal mines. The device adopts integrated circuit, frequency selective amplification, good anti-interference, easy to use, electromagnetic valve with strong water pressure, flexible and reliable action.
Features
The device passes through the main control box of the mine automatic sprinkler dust-reducing device, and the mine explosion-proof solenoid valve is equipped with sensors of various functions to realize automatic control of spraying or watering. The specific features are as follows:
1) Induction and stoppage function 2) Roadway spray computer control by shift and Sunday setting function
3) Single pulse touch sprinkling function (mainly used in rubber car transport and coal car transportation occasions or shooting) 4) Remote control and remote control functions, centralized control of console and dispatch center
5) Automatic water addition function of anti-burst facilities 6) Belt conveyor and transfer point dust reduction function
7) Dust and fireproof function of belt head 8) Intermittent watering function (clock pulse sprinkling)
9) Shearer transfer spray function

Connection sensor type
1)Sound-sensing sensor and vibration sensor for ZP-12S mine automatic sprinkler dust-reducing device
Working voltage: 5~13V, DC working current: ≤2mA
Input signal: Acoustic signal Output signal: Switching signal.
When the background sound is not more than 60dB, when the sensor's voice sensor receives ≥90dB sound wave, the sensor turns on and outputs the open signal; when the sensor's voice sensor has no sound wave, the sensor is disconnected and the output has no signal output.
2) Touch sensor for ZP-12S mine automatic sprinkler dust reducer
Working voltage: 12V, DC working current: ≤20mA
Input signal: Proximity switch signal Output signal: Switch signal.
When the connecting rod is triggered, when the distance between the sensor and the metal object increases, the sensor is turned on and outputs an open signal; in the static state, the sensor is close to the metal object, the sensor is disconnected, and no signal is output at the output end.
3) Light control sensor for ZP-12S mine automatic sprinkler dust reducer
Working voltage: 12V, DC working current: ≤20mA
Input signal: light wave signal Output signal: switch signal.
When the ambient brightness is ≥10 Lux, the sensor is turned on and the output signal is output; when the ambient brightness is ≤10 Lux, the sensor is turned off, and the output has no signal output.
4) Infrared sensor, pyroelectric sensor, water level sensor for ZP-12S mine automatic sprinkler dust reducer
Working voltage: 12V, DC working current: ≤35mA
Input signal: Infrared signal Output signal: Switching signal.
In the condition of obstruction, the sensor is turned on and outputs an open signal; in the absence of obstruction, the sensor is disconnected and no output is output at the output.
5) Temperature and smoke sensor for ZP-12S mine automatic sprinkler dust reducer
Working voltage: 5 ~ 13V, DC
Working current: ≤20mA
Input signal: temperature, smoke signal
Output signal: switch signal. When the temperature is ≥65°, the sensor is turned on and the output signal is turned on;
When the temperature is ≤60°, the sensor is disconnected and there is no signal output at the output.
