我厂处理污水用的泵F型曝气机(相当于BQ-15A型),原结构采用蜗轮和蜗杆减速机,蜗杆-端和调速电动机通过联轴器连接,蜗杆轴两端装有7618轴承各一套。在靠调速电动机一端轴封的动密封处,装有一个φ70×φ95×12毫米的耐油橡胶骨架油封。机轴采用30号机械油润滑。因原机轴封仅有一道油封,密封效果较差,漏油严重,每天每台用油5公斤。据此,我们在轴封端盖到联轴器蜗杆轴较长的一段空隙上,经改装后多装了几道油封,结果取得了很好的效果,具体作法是(如图):
I used to deal with sewage treatment plant pump F-type aerator (equivalent to BQ-15A type), the original structure of worm gear and worm reducer, worm-side and speed motor connected through the coupling, the ends of the worm shaft equipped with 7618 A set of bearings. In the dynamic motor seal by the end of the dynamic seal, equipped with a φ70 × φ95 × 12 mm oil-resistant rubber skeleton seal. Shaft with No. 30 mechanical oil lubrication. Because the original shaft seal only one oil seal, sealing effect is poor, serious oil spill, every day 5 kg of oil. Accordingly, we seal the end cap to the coupling shaft of a longer worm, the modified multi-installed a few seals, the results achieved good results, the specific approach is (pictured):
