Part of the exhaust fan exhaust fan of a structure type, blowing section casing 2, Group 3 impeller, the wind bends 4, the inner cylinder 5, the support plate 6, motor 7, the wind pipe as shown, since The basic structure type cooling type exhaust fan with the same general fire temperature exhaust fan, is composed of an inner cylinder and an outer cylinder, impellers, bushings, motors, baffle size and position unchanged. The inner cylinder, the size and location of the outer cylinder in the axial direction essentially unchanged. Two about the wind pipe 7 is arranged in the lateral distribution of the outer tube ends, the front end of the inner tube means the wind trap 3, remove the inner loop impeller group. Works: the heat from the fire temperature exhaust fan aerodynamically designed, when the fan is working, the outer cylinder transport temperature flue gas or induction of ordinary gases, the inner cylinder exhaust gas from the wind bend, since the inner cylinder gas emissions the inner cylinder gas pressure reduction, fire exhaust fan, duct outside air into the cylinder inside, exhaust fan from the wind pipe to the motor cooling air from the inner tube into the elbow, lower the temperature inside the fan cylinder completely air-independent since the cycle is completed, to ensure the normal operation of the fan. Exhaust fan which of several parts of it? 1. Filter: filter equipment according to customer needs, specifications and equipment unworthy belt filter. 2, motor: exhaust fan choices are Y series three-phase asynchronous motors, specializing in the production of exhaust fan, with high efficiency, good performance, low noise, small oscillations and other characteristics. 3, the fan: exhaust fan unit chosen package of imported brands, double inlet centrifugal fan with high residual pressure, air volume, smooth operation, exhaust fan principle, and check through the whole dynamic equilibrium, that the power to reach The highest and lowest noise. 4, layout and panel: selection of corrosion by the use of exhaust fan, distribution leadership, exhaust fan for easy field maintenance removable aluminum layout layout; inner board attached silencer cotton, outside board electrolytic plate or galvanized plate appearance maintenance spray coating selection, the oxide layer and the outer coating of electrolytic plates constitute double maintenance, high strength all layout, good noise performance; small wind units can use two-panel layout steel.
