◆ Work purpose It is mainly used in the main roadway, transportation belt roadway, return air roadway, bottom of the well, parking lot and other places. Reduce the concentration of coal dust, carbon monoxide and gas, and improve the working environment. Features: The device sets the spraying time is simple and fast, according to the needs of the user to spray, stop spraying and delay time setting is generally designed to spray regularly and regularly phased spraying, when people come to the car to stop spraying, after the person and car, re-automatic spraying, to prevent spraying passing people and vehicles. The host can be sprayed at regular intervals through the remote control, and multiple time periods can be set to save water resources and reduce the burden of underground drainage. The host uses wireless signals for data transmission between the host and the sensor, and the host analyzes the received external data and controls it logically, so as to realize the wireless wine dust reduction function. ◆ Technical parameters Operating voltage: 12.8VDC Operating current: ≤0.3A Ambient temperature: 0°C~40°C Enclosure rating: IP65 Intrinsically safe parameters: Ui: 14.8V, Ii: 0.3A, Ci: 1.2μF, Li: 10μH Explosion-proof mark: ExiblMb Explosion-proof certificate: CCCMT22.0425 Safety sign number: MDC220079 Warning: It is strictly forbidden to charge and disassemble the battery underground Battery intrinsic safety parameters: Uo: 4.5V, 1o: 3A
