FAG explosion-proof exhaust fan is driven by the motor to rotate the air flow of the fan blade, so that the indoor and outdoor air exchange is a type of air conditioning appliance. The purpose of the exhaust is to remove the dirty air in the room and adjust the temperature, humidity and sensory effects. Exhaust fans are widely used in homes and public places.
FAG explosion-proof exhaust fan installation and use:
1, first check the frame, the wind blade has no deformation, whether the blade rotation is flexible, there is no friction phenomenon. Check all fasteners are complete, tighten, explosion proof certificate number.
2. The line voltage must match the rated voltage on the motor.
3. Check the insulation resistance of the motor with a 500V megohmmeter. If the resistance value of the motor is less than 5MΩ, apply a drying method or a short-circuit current method to dry it so that the insulation resistance is greater than 5MΩ.
4, must be equipped with a small explosion-proof switch for the power switch, or the general switch installed outdoors without explosive danger.
5, the outer diameter of the power cable should be consistent with the sealing ring, after tightening, pressing the nut should ensure that there is no gap between the sealing ring and the cable, between the sealing ring and the emergence of the nozzle, otherwise it will lose its explosion-proof performance.
6, the assembly should ensure that the explosion-proof gap is less than 0.2mm, replace the motor bearing grease, the grease brand ZG-2H complex calcium base Run.
7. The non-wiring part of the explosion-proof motor can not be disassembled freely. When wiring, open the cover of the wiring room and insert the lead wire into the terminal. After the connection is completed, tighten the Screw on the cover to make the gap between the explosion-proof surface less than 0.2mm, then tighten it. Outlet, so that the lead can not shake.
8. The FAG explosion-proof exhaust fan in use should always clean the dust and other accumulations on the motor so as not to affect the heat dissipation.
9. When the FAG explosion-proof exhaust fan that is not used for a long time is used again, it should be checked again according to the instructions, and it can be used after it is suitable.
Note: When installing, pay attention to the flameproof surface. The explosion-proof surface must be coated with 204-1 rust-proof grease. All explosion-proof surfaces shall not be damaged or rusted, otherwise they will lose their explosion-proof performance. If there is any damage or rust, repair shall be carried out in accordance with the "Regulations on the Handling of Explosion-Proof Electrical Equipment Explosion-proof Surfaces."

Self drilling screw made of 410 stainless steel, high hardness (40 Rockwell C), steel process.
Drilling screw is also very strong hardness, compared to the ordinary screw up, not only to maintain the ability is good, the connection object effect is also very strong, for the performance of the screw, are generally does not need auxiliary processing, can be directly on the object directly drill a Kong Sue into objects, not just use rise very convenient, Also can greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of workers in various fields.
So what is the use of drilling screws?
1 stainless steel plate, metal plate, galvanized steel plate, engineering installation.
2 metal curtain wall metal light compartment and other indoor and outdoor installation.
General Angle steel, channel steel, iron plate and other metal materials combined installation.
4, automobile, container, shipbuilding, refrigeration equipment and other assembly projects.
