Exhaust fan installation and maintenance: a kitchen fan is indispensable key kitchen equipment, it is recommended not to install in the ceiling as possible, to be installed in the engine room, the roof or exterior wall to facilitate maintenance of the place. Second, the kitchen fan because of long working hours in hot, humid, gas fumes. Regular maintenance is indispensable work. Point of failure: 1, resulting in greasy impeller blade curvature, angle deformation price exhaust fan fire, wind parameters significantly decreased total pressure exhaust fan fire, smoke can not reach the requirements. 2, the impeller oil stains cause impeller to lose balance, increased vibration, bearing damage. 3, harsh environments easily corroded parts low price promotions exhaust fan fire, damage the fan. On the air, exhaust fan maintenance: (1) whether the combustible air around the room; mounting bolt is loose, injury; (2) the transmission mechanism is deformed, damaged; impeller is in contact with the casing; (3) the motor wiring is loose; the motor housing for corrosion phenomenon; (4) the power supply is normal (check voltmeter or power indicator). If (5) Check the bearing part lubricants abnormal state (dirty, mixed with sand, dust, etc.); (6) Check motor oil level is normal bearing parts; (7) Check for loose drive belts, couplings whether the firm; (8) to start the motor, rotates without abnormal vibration, noise.
