ZPR-127矿用热释光控自动洒水降尘装置 ZPR-127 mine heat release light controlled automatic sprinkling and dust reducing device An instruction manual Executive Standards: GB3836-2000, MT503-1996, Q/320683YYJD01-2009 Version number: NO.1 Date of publication: 2009-01-01 Nantong Yu Yu Machinery Electronic Industry Co., Ltd. Warning: 1., no open cover in the pit maintenance! The electrical parameters and specifications shall not change the intrinsically safe circuits and intrinsically safe circuit components associated with the 2. maintenance! 3. safety related products are not free to change the configuration! 4., strict maintenance should pay attention to prevent explosion (protection against flameproof surface, pay attention to fastening, the introduction of rubber seals in the device)! 1 Overview ZPR-127 mining light controlled light automatic sprinkling and dust reduction device (hereinafter referred to as control device) is suitable for automatic control of water spraying and spray control of coal mining face, roadway, ventilation purifying water curtain and belt loader point. The device is equipped with KXJ-0.5/127 mine flameproof and intrinsically safe power control box and DFB-4/8 mine flameproof electromagnetic valve, so as to realize automatic control of spraying or sprinkling function. Spraying or sprinkling can not only realize dust control and dust reduction, but also reduce the concentration of harmful gases. It will play an important role in effectively preventing the damage of pneumoconiosis and ensuring the safe production of coal mines. The device adopts an integrated circuit, frequency selective amplification, good anti-interference, convenient operation, strong electromagnetic pressure bearing, flexible and reliable action. Strictly follow the GB3836.1-2000 device electrical apparatus for explosive gas atmospheres Part first general requirements, GB3836.2-2000 electrical apparatus for explosive gas atmospheres Part second: Flameproof Enclosure d and GB3836.4-2000 el
