Installation and maintenance: the kitchen fan is indispensable key kitchen equipment, recommended not installed in the ceiling, to be installed in the engine room and so on, roofing or exterior wall for easy maintenance of the place. Working kitchen fan due to prolonged high temperatures, humidity, smoke gases. Regular maintenance is indispensable work. Failure: 1, the impeller blade leads to oily curvature, angle deformation, air volume total pressure parameters decreased significantly, reaching less than exhaust requirements. 2, the impeller oil stains causes the impeller to lose balance, increase shock, damage to the bearings. 3, harsh environments parts easily rust, damaged fan. Fire exhaust fan life by what elements impact modified: 1, fire exhaust fan impeller hanging water equipment Converter Dust Fan task BOF emissions occur as flue gas. Due to various reasons. Fans from the flue into the flue gas dust content is high, after the dust touch wheel to follow suit. Adhered to the surface of the fan impeller, piled up, and it is difficult to arrive balance, thus constituting fire exhaust fan impeller imbalance due to oscillate. 2, three outfall fan shoulders due converter dust and gas recovered two tasks on the blower out of the wind pipe, equipment three-way valve. Transform manifold gas recovery time, when the gas recovery, the three-way valve is open, the converter through the three-way valve inflow flue gas tank, complete gas recovery. When the gas recovery is completed, the three-way valve is closed by the three-way valve inflow chimney flue, chimney discharged into the atmosphere through. 3, fire exhaust fan casing sewage pipes in the transformation of the Chongqing fans fan impeller Sprinkler later. Less sludge on the impeller fan, and most are washed down, exhaust fan, through the device in the bottom of the fan casing sewage pipe inflow seal the well. Because the pipeline is relatively long, to the irrational, turn more. Coupled with planned nominal pipe diameter of only 50mm, constituting the pipeline often blocked. Once the pipes get clogged, fire exhaust fan inside the cabinet will soon be covered with water, but assuming that is not timely, will constitute a fan vigorous shaking, triggering bearing damage, exhaust fan price, fan bearing crack, which serious consequences can be imagined. Influence the life of the primary exhaust fan fire by these factors, we must be reasonable to use it, just so get plenty of talent to make it function display, trek our work efficiency.
