Novel sealing fan for offshore wind power

Abstract

The invention discloses a novel sealing fan for offshore wind power. The novel sealing fan comprises a motor, an impeller, and a mesh cover, the motor comprises a motor shaft connected with the impeller, and a motor flange connected with the mesh cover, a mesh cover flange corresponding to the motor flange is arranged in the middle of the mesh cover, and a through hole allowing the motor shaft topenetrate through is formed in the middle of the mesh cover flange. A first sealing connection assembly is arranged between the impeller and the motor shaft, and a second sealing connection assembly is arranged between the motor flange and the mesh cover flange. According to the novel sealing fan for the offshore wind power, gaps at the joints of the fan are reduced through the first sealing connection assembly and the second sealing connection assembly, the tightness is improved, thus corrosion and rust of the joints are reduced, and the service life of an air blower is prolonged.

Description

technical field [0001] The invention relates to the field of offshore wind power, in particular to a novel sealed fan for offshore wind power. Background technique [0002] Offshore wind power is an important clean energy, because it has the characteristics of high wind speed, stable wind frequency, small shear, rich resources, no land occupation, suitable for large-scale development, etc., and offshore wind power is close to economically developed areas, far away from power load The center is close, the power consumption capacity is strong, and there are no problems such as access and power limitation, etc., and it has developed rapidly in recent years. [0003] The water-cooled fan is an important working part of offshore wind power. It is generally installed outside the cabin. The fan is a part of the water-cooled fan. It is mainly composed of three parts: the motor, the impeller, and the grille. During installation, the flange surface of the motor and the flange surface...

AI Technical Summary

Problems solved by technology

In order to meet the high salt spray requirements at sea, the exposed parts of the water-cooled fan are made of high anti-corrosion materials, but there are inevitably gaps at the connection between the motor, the grille and the impeller, and rainwater or humid air will enter the connection from the gap. In addition, because the motor will generate heat when it is working, the temperature difference between inside and outside will cause condensed water inside the motor. If the condensed water leaks from the threaded part of the motor shaft, it will also cause corrosion and rust, and then Affect the operation of the fan, resulting in a reduction in the service life of the fan
