Abstract
The utility model relates to a horizontal draught fan driving direct air-cooling condenser which comprises a draught fan (1), a reducer (2), a motor (3), a supporting platform (5), a tube bundle, a support (6) and a transmission shaft (7), wherein the reducer (2) and the motor (3) both utilize horizontal type installation types, and a transmission output shaft of the reducer (2) is placed in the perpendicular direction. A transmission input shaft of the reducer (2) is perpendicular to the transmission output shaft, a transmission shaft (7) is placed in the horizontal direction, the motor (3) is connected with the transmission input shaft of the reducer (2) through the horizontal transmission shaft (7), and the transmission output shaft of the reducer (2) is connected with the draught fan (1). The horizontal draught fan driving direct air-cooling condenser reduces cost, reduces shaft sealing leakage oil, and prolongs service life of the motor.
Description
Technical field
The utility model relates to a kind of direct air cooled condenser.Be mainly used in the exhaust steam in steam turbine cooling of the industries such as electric power, chemical industry.
Background technology
The direct air cooled condenser cooling segment is comprised of heat-exchanging tube bundle and support, support platform, blower fan and air duct, motor, reductor etc.The wind that the exhaust steam that steam turbine comes is sent here with blower fan in heat-exchanging tube bundle carries out heat exchange, makes steam condensation Cheng Shui.
Direct air cooled condenser comprises blower fan, motor, reductor and support platform, tube bank and support etc. at present.Blower fan, motor, reductor are installed on the fan bridge of air cooling tubes condenser bottom, gear-box, motor vertical, and assembling is below reductor.Reductor adopts parallel axes, and the transmission power shaft is upper, and transmission output shaft adopts bolt that the reductor base plate is connected on the fan bridge lower.The vertical type speed reducer (change gear) that this drive unit adopts, not only cost is higher, and the easy leakage of oil in end cap seal place of power shaft and output shaft.Blower fan, gear-box, motor are installed on the fan bridge of steel construction in addition, and the power of disturbing during fan operation makes fan bridge produce vibration, brings potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of deficiency of direct air cooled condenser vertical driving device is provided, reduces cost, solve the shaft seal leakage of oil, reduce the vibration that excitation of fans produces, the Horizontal fan that improves security performance drives direct air cooled condenser.
The purpose of this utility model is achieved in that a kind of Horizontal fan drives direct air cooled condenser, comprise blower fan, reductor, motor, support platform, tube bank and support and power transmission shaft, be characterized in: reductor and motor all adopt horizontal installation form, the transmission output shaft of reductor is positioned at vertical direction, the transmission power shaft of reductor is mutually vertical with transmission output shaft, power transmission shaft is positioned at horizontal direction, and motor links to each other with the transmission power shaft of reductor by the power transmission shaft of level; The transmission output shaft of reductor links to each other with blower fan.
The beneficial effects of the utility model are:
1, reductor and motor all adopt horizontal installation form, have reduced cost.
2, utilize the characteristics of not easy oil leakage of Horizontal speed-reducer to solve Leakage.
3, motor changes into horizontally by vertical, and rolling bearing is stressed evenly, has prolonged service life.
4, can be without fan bridge, reductor and blower fan are directly installed on the brace summer, reduce the vibration that excitation of fans produces, and have improved security performance.
