炼油工业的旋转设备很多,常有轴承甩润滑油的现象发生。就我厂现用的离心泵作一下调查,许多泵存在着轴承箱甩油现象,它不但浪费润滑油,使轴承发热、振动,以致烧毁轴承,发生抱轴事故。而且由于振动引起轴封失效,被密封的高温介质漏出就会发生着火等重大事故。在热油泵房,甩出的润滑油被电机风扇吹到泵出入口管线上,引起冒烟,造成泵房 There are many rotating equipment in the oil refining industry, often bearing lubricant rejection phenomenon. On the centrifugal pump I used to make some investigations, many pumps bearing oil rejection phenomenon, it is not only a waste of oil, the bearing fever, vibration, so that the bearing burned, the occurrence of axle accidents. And because the shaft seal caused by vibration failure, leakage of sealed high temperature medium will occur a major accident, such as fire. In the hot oil pump room, thrown oil is blown to the pump inlet and outlet lines by the motor fan, causing smoke, causing the pump room
