我厂鼓风机、引风机的传动部分是由电机通过弹性联轴器直接驱动风机轴,其上装有两只双列向心球面罐子轴承,通过油池来润滑轴承,为防止泄漏原设计采用隙缝密封并配有甩油环,但泄漏相当严重。泄漏原因:当甩油环把润滑油甩在端盖内孔壁后,油液将沿孔壁表面流到甩油环背面的风机轴上。孔与轴之间的间隙为0.1～0.3mm,由于风机转速很高(约1000r/min),难以形成油膜阻止泄漏。为此,我们试制了铝环密封装置。
I plant blower, induced draft fan drive part of the motor shaft is directly driven by a flexible coupling fan shaft, which is equipped with two double row radial spherical canister bearings through the oil pool to lubricate the bearing, in order to prevent leakage of the original design using slit seal And equipped with oil slinger, but the leak is quite serious. Leakage reasons: When the oil thrown oil ring thrown in the end cap hole wall, the oil flow along the surface of the hole wall to the thruster on the back of the fan shaft. The gap between the hole and the shaft is 0.1 ~ 0.3mm, due to high fan speed (about 1000r / min), it is difficult to form a film to prevent leakage. To this end, we trial-produced aluminum ring seal.
