DWT-Ⅳ-type non-motor turbine exhaust machine 1, DWT-Ⅳ-type non-motor turbine exhaust machine Overview ???? 1.1.DWT-Ⅳ-type non-motor turbine exhaust fan, the use of natural wind driven blade operation, due to the centrifugal force of the air operation flow, due to the very thin blade, even a faint breeze also make it turn. When the turbine rotates, centrifugal force is generated, the bottom of the hot air turbine, flue gas, wet gas is sucked up and discharged. When air is pulled turbine, it is conveniently formed area of ??low pressure turbine, namely chimney effect. Since the turbine continues to rotate, the outdoor fresh air will continue to flow into, then reach the cooling effect of natural ventilation. ???? 1.2.DWT-Ⅳ-type non-motor turbine exhaust machine without electricity, continuous operation, high efficiency, no noise, no spark. Exhaust fan with arc-shaped leaves, there is a gap between each blade and the blades, each blade is rotated to fill the seats to fill these gaps, a lot of rain along the section line thrown round, a small amount of rain measured along the leaf and slice living roof, will not flow into the turbine, the turbine rotates while the air flowing from the blade gap, blocking rainwater from entering, with weatherproof. Exhaust fan is fully enclosed ball bearing, lightweight stainless steel blade, light weight, long life, generally more than 15 years of life. 2, DWT-Ⅳ-type non-turbo exhaust fan motor operating conditions ???? Operating temperature: -20 ℃ ~ + 80 ℃; ???? temperature: <90%; ???? media conditions: air (dust content not more than 100mg / 3). ???? Power supply: three-phase, 380V / 50Hz. 3, DWT-Ⅳ-type non-motor turbine exhaust machine application ???? used in factories, warehouses, rooftops of buildings, villas, patio, greenhouse, livestock breeding, and all mine tunnel roof ventilation, ventilation. 4, DWT-Ⅳ-type non-motor turbine exhaust machine configuration ● impeller; ● bracket; 5, DWT-Ⅳ-type non-motor turbine exhaust machining process ???? fan impeller blades made of stainless steel curved blade and die of the molding. 6, DWT-Ⅳ-type non-motor turbine exhaust machine parameter table 7, DWT-Ⅳ-type non-motor turbine exhaust installation schematic illustration ???? In order to achieve maximum efficiency turbo fan engine, location of the installation must be high on the roof, Avoiding a parapet or may be installed in the vicinity of the high-rise block, where trees winds. within a. turbine exhaust fan b. Either edge steel backbone cover must be inserted? c. must be greater than the flat steel plate mounting holes after area d. steel split down the two measured at right angles to the peak of the roof must cover e. Adjust seat f. mounting holes
