How to prevent electric ventilation fan caused the fire?

Electric ventilation fan casing is generally constituted by two materials of plastic and metal. Electric ventilation fan in the transmission machinery and fixed parts are generally plastic, rubber, metal three materials. Electric ventilation fan of many parts, each part of the materials used, such as motors, reactors, timer, and a variety of switching elements constituent materials and special.

1. Strictly control the use of the electric ventilation fan time.

2. Annual enable electric ventilation fan should drip oil motor fuel hole, the rotating friction parts to maintain lubrication will not produce high temperature; motor I usually wipe with a clean rag to remove dust buildup on the housing.

3. The motor does not use water moisture; not in places where explosive flammable liquids. Choose smooth and firm position to put electric ventilation fan, prevent knocked over and damaged fan blades and motor.

4. Regular checks of electrical components and power cord connections are secure, the power cord is old and damaged, and found that the issue should be timely maintenance and replacement must not "sick".
