Abstract
The utility model relates to a large-diameter axial-flow fan which belongs to mechanical ventilation equipment arranged on a power station direct air-cooled condenser device and matched with thermal power generation set equipment, in particular to a large-diameter axial-flow fan device. The utility model is characterized in that a propeller blade of the fan is arranged in a wind tube of a fan case, one end of a long shaft of a motor is connected with the propeller blade of the fan through a hub flange, the other end of the long shaft is connected with a low-speed permanent-magnetism synchronous electric motor, and the low-speed permanent-magnetism synchronous electric motor is arranged in a support frame of the fan. The large-diameter axial-flow fan device has the advantages of simple structure, low cost, high integral efficiency of a system, long service life, short starting time, small starting current, small power distribution capacity and the like, is easy to operate and use, is convenient to install, repair and maintain because of simple structure, is reliable to operate and reduces the total weight of the fan.
Description
Technical field: it is the mechanical ventilation equipment that is disposed on the supporting power station direct air-cooling condenser arrangement of thermal power generation complete equipment that the utility model relates to the major diameter axial-flow blower, is specially a kind of major diameter axial-flow blower device.
Background technique: mostly be 9.14 meters (30 feet) at impeller diameter at present for the supporting major diameter axial-flow blower in 600MW direct air cooling power station, its drive mechanism is that squirrel-cage asynchronous motor drives a parallel axis hard-tooth surface multi-stage gear speed reducer, and the output terminal of speed reducer drives a multiple-blade propeller cavitation impeller again and turns round for heat exchanger tube required air quantity, blast is provided.
Summary of the invention: the purpose of this utility model is, provide a kind of simple in structure, with low cost, installation and maintenance convenient, energy-conservation major diameter axial-flow blower device.The purpose of this utility model is achieved in that it comprises low-speed permanent-magnet synchronous motor, blower fan propeller blade, flow blower casing air duct, pavement guardrail, crane span structure girder, blower fan supporting frame, wheelboss flange, motor major axis.In the flow blower casing air duct, be provided with the blower fan propeller blade, motor major axis one end through wheelboss flange be connected with the blower fan propeller blade, the other end is connected with low-speed permanent-magnet synchronous motor, is provided with low-speed permanent-magnet synchronous motor in the blower fan supporting frame.The utility model has the advantages that: use simple in structure, with low cost, easy to operate, easy to maintenance.The utility model has at first adopted 32 utmost point low-speed permanent-magnet synchronous motors as motivational drive on 10.973 meters (36 feet) major diameter axial-flow blowers, the asynchronous motor of it and transmission and electromagnetism synchronous machine maximum different have been to use advanced rotor structure, the exciting winding that has replaced the squirrel cage rotor or the synchronous machine of asynchronous motor with the efficient permanent magnet material, considerably less from the field current of electrical network absorption like this, compare the power factor height with asynchronous motor, just required converter power supply capacity is also just relatively little; Compare with synchronous machine, reduced rotor-exciting slip ring and regulator, do not had excitation loss.Because motor and blower fan direct connection save shaft coupling and gear reduction box, and structure is simplified greatly.Traditional gear reduction box and clutch shaft coupling are not only installed trouble, and the lubricated maintenance of gear and bearing and maintenance are also pretty troublesome, and workload is big, and the transmission of 2-3 level gear-box will have the energy consumption about 4%, and direct connection can be saved this part energy consumption.The utility model also has: system synthesis efficient height, and the maintenance that is easy for installation and maintenance simple in structure, reliable, long service life, lack starting time, and inrush current is little, and distribution capacity is little, and the blower fan overall weight such as alleviates at advantage.
Description of drawings: Fig. 1 is the utility model structural principle schematic representation; Fig. 2 is the utility model low-speed permanent-magnet synchronous motor and blower fan propeller blade, blower fan supporting frame linkage structure principle schematic.
Embodiment: it comprises low-speed permanent-magnet synchronous motor 1, blower fan propeller blade 2, flow blower casing air duct 3, pavement guardrail 4, crane span structure girder 5, blower fan supporting frame 6, wheelboss flange 7, motor major axis 8.In flow blower casing air duct 3, be provided with blower fan propeller blade 2, motor major axis 8 one ends through wheelboss flange 7 be connected with blower fan propeller blade 2, the other end is connected with low-speed permanent-magnet synchronous motor 1, is provided with low-speed permanent-magnet synchronous motor 1 in the blower fan supporting frame 6.Working principle of the present utility model is: the low-speed permanent-magnet synchronous motor energising is after the motor major axis rotates, and drive wheelboss flange, blower fan propeller blade rotate and start working, and the configuration variable-frequency governor is controlled corresponding air quantity and blast requirement under the variable working condition.
