Sprinkler Dust Device Recommended Products
Introduction of Sprinkler Dust Device
Sprinkler dust device by the sprinkler dust control device main control box, ZP-9S mine automatic sprinkler dust device with voice sensor, and the actuator mine explosion-proof solenoid valve and other components, mainly used for coal mining underground dust mining workplace. Through automatic spraying or sprinkler, not only clean dust, clean air, while absorbing a certain amount of harmful gases, reduce methane concentration and ambient temperature. It is to improve and control the dust operating environment, prevention and control of dust hazards, safety management equipment.

Sprinkler dust installation and using
1, according to the size of the roadway to do a suitable water curtain, water curtain with high pressure water pipe connected with the device outlet. The inlet is connected to the main water pipe.
2, the sensor installed in the roadway wall or the top wall, according to the wind direction, wind speed and other conditions to determine the length of the distance between the sensor and the host.
3, spray time adjustment: through the computer to modify the host PLC program, you can achieve any adjustment of the spray time.
