FAG-400120W防爆排风扇直径400安装孔尺寸300×300依客思安装和使用

◆ 首先检查框架、风叶有无变形，扇叶转动是否灵活，有无摩擦现象。检查所有坚固件是否齐全、拧紧，应有防爆合格证编号。

◆ 线路电压必须与电机上额定电压相符。

◆ 用500V兆欧表检查电动机的绝缘电阻，其电阻值若小于5MΩ，则应用烘干法或短路电流法进行干燥处理，使其绝缘电阻大于5MΩ。

◆ 必须配用小型防爆开关作电源开关，或将普通开关安装于室外无爆炸性的地方。

◆ 接电源的电缆外径与密封圈相符，拧紧、压紧螺母后应保证密封圈与电缆间，密封圈与出线咀间无间隙，否则将推动隔爆性能。

◆ 装配时就保证防爆间隙小于0.2mm，更换电机轴承的润滑脂，其润滑脂牌号为ZG-2H复合钙基润。

◆ 防爆电动机非接线部分不可随意白拆卸，接线时，打开接线室的盖，穿入引线接到端子上，接了后，盖上盖拧紧螺钉使其隔爆面间隙小于0.2mm，再上紧出线器，使引线不能窜动。注意：安装时，注意隔爆面。装配时隔爆面须涂204-1防锈油脂。所有防爆面不得有损伤或锈蚀，否则将失去防爆性能，如有损伤或锈蚀现象需按《防爆电气设备防爆面缺陷处理的规定》进行补修。

◆ 使用中的排风扇 应经常清扫电机上粉尘及其它积聚物，以免影响散热。

◆ 长期不用的排风扇重新使用时，应按说明书再检查一遍，合适后方可使用。

First check whether the frame, blade deformation, blade rotation is flexible, there is no friction phenomenon. Check whether all solid parts are complete and tight, there should be explosion-proof certificate number.
Line voltage must be in accordance with the rated voltage of the motor.
◆ With 500V megohm meter to check the insulation resistance of the motor, if the resistance value is less than 5M ω, then the application of drying method or short circuit current method for drying treatment, so that the insulation resistance is greater than 5M ω.
◆ Must be equipped with small explosion-proof switch as power switch, or the ordinary switch installed in the outdoor without explosive place.
◆ The outer diameter of the cable connected to the power supply is consistent with the sealing ring. After tightening and pressing the nut, there should be no gap between the sealing ring and the cable, and between the sealing ring and the outlet nozzle, otherwise it will promote the flameproof performance.
◆ When assembling, ensure that the explosion-proof gap is less than 0.2mm, replace the grease of the motor bearing, the grease brand is ZG-2H composite calcium base run.
◆ The non-wiring part of the explosion-proof motor can not be disassembled at will. When wiring, open the cover of the wiring room and put the lead wire into the terminal. After connecting, tighten the screw on the cover to make the flameproof surface gap less than 0.2mm, and then tighten the outlet, so that the lead can not move. Attention: pay attention to the flameproof surface when installing. The flameproof surface shall be coated with 204-1 antirust grease during assembly. All explosion-proof surfaces shall not be damaged or rusted, otherwise the explosion-proof performance will be lost. If there is damage or rusted phenomenon, it shall be repaired according to the Provisions of Explosion-proof Electrical Equipment Explosion-proof Surface Defect Treatment.
◆ The exhaust fan in use should often clean the dust and other accumulation on the motor, so as not to affect the heat dissipation.
◆ When the exhaust fan that is not used for a long time is re-used, it should be checked again according to the instruction and can be used properly.
