Abstract

本实用新型涉及锅炉引风机组安全运行技术领域,特别是涉及一种锅炉轴流式引风机主轴承箱、液压缸与电机一体冷却装置,包括:引风机驱动电机(1)、外冷却风扇(2)、空-空冷却器(3)、辅助冷却风机(4)等,其特征在于:引风机驱动电机(1)前端设有与其同轴的外冷却风扇(2),其出口风道与引风机驱动电机(1)顶部的空-空冷却器(3)入口连通;外冷却风扇(2)出口风道设有备用接口还与辅助冷却风机(4)出风管连接。本实用新型的有益效果有:彻底避免了现有技术轴承箱冷却风机发生故障而引起引风机跳闸问题,提高了引风机组运行的安全性,简化了引风机启动、跳闸条件,降低了引风机组自身的冷却能耗。
The utility model relates to a boiler induced -draft fan group security moves technical field, especially relates to an integrative cooling device of boiler axial -flow type draught fan base bearing case, pneumatic cylinder and motor, include: draw fan drive motor (1), outer cooling fan (2), sky - sky cooler (3), auxiliary cooling fan (4) etc. Its characterized in that: draw fan drive motor (1) front end and be equipped with rather than coaxial outer cooling fan (2), its export wind channel and sky - sky cooler (3) the entry intercommunication that draws fan drive motor (1) top, outer cooling fan (2) the export wind channel be equipped with reserve interface still with auxiliary cooling fan (4) air -out union coupling. The beneficial effect of the utility model have: thoroughly avoid prior art bearing box cooling blower to break down and caused draught fan tripping operation problem, improved the security that the induced air unit moved, simplified draught fan start -up, tripping operation condition, reduced the cooling energy consumption of induced air unit self.
