Automatic sprinkler dust suppression device temperature control automatic sprinkler dust suppression device intrinsically safe many types of the company's products, but also for a wide range, with intrinsically safe quality products, and this product is one of my company's flagship product in the country and more features subsidiaries and offices, while products are well recognized in line with the national security inspection certificate. Such products are mostly mining, roadway, as well as high-risk places to use! Therefore, these products must be regular, qualified, excellent quality of high-quality products. Here is an overview of our products, one of these products! ? First, dust suppression device ZPQW127 automatic sprinkler dust suppression device Overview: Model: ZPQW127 ZPQW127 mine smoke thermostat automatic sprinkler dust suppression device Uses: mainly used for coal transport belt Lane, flammable parts of the belt, nose, tail and other automatic sprinkler, fire extinguishing dust played a role. ? Two, ZPQW127 automatic sprinkler dust suppression device characteristics dust suppression device: automatic sprinkler dust suppression device performance characteristics: power, the electric ball valve is closed, the delay 6 seconds master box starts to detect the temperature and smoke sensors. When both or one of the signal output, the main control box control electric ball valves open sprinklers. Neither signal when the output of the delay device starts watering. Delay time 0s-270s adjustable end delay, the main control box control electric valve shut-off valve. During the delay, if the sensor signal output have to wait for the sensor signal disappears again after the set time delay before they stop watering. ? Third, dust suppression device ZPQW12 automatic sprinkler dust suppression device: the automatic sprinkler dust suppression device component; ZP-127Z mine dust means automatic sprinkler control box, GQ.Q0.1 mine safety type smoke sensor, GWD60 mine temperature sensors, DFH-20/7 mining intrinsically safe electric ball four, ZPQW127 automatic sprinkler dust suppression device parameters Technical parameters dust suppression device rated voltage:?
