JK-1500-2型电动机具有结构简单、使用和检修方便等优点,因此,炼铁高炉用的鼓风机组的带动大多采用这种电动机。但是,这种电动机原采用油环式滑动轴承,漏油严重。且两轴承均安装在电机两端的端盖上,距冷却电动机进风处很近(图1),容易造成漏出的油顺电动机吸风被吸到电动机定子内,使电机定子线圈充满透平油,影响电机的绝缘性能,给 JK-1500-2-type motor has the advantages of simple structure, easy use and maintenance, etc. Therefore, the blast furnace blast furnace used mostly driven by this motor. However, the original use of oil-type motor sliding bearings, serious oil spills. And both bearings are mounted on both ends of the motor cover, away from the cooling motor into the wind very close (Figure 1), likely to cause leakage of oil along the motor suction is drawn into the motor stator, the stator coil of the motor filled with turbine oil , Affect the motor insulation, to
