各工业部门用的旋转设备很多,常有轴承漏油的情况,它污染环境,浪费润滑油,使轴承发热,或烧轴承、抱轴,甚致损坏有的设备所带的密封,使被密封的易燃、易爆、有毒等介质漏出,发生着火或中毒事故。因此,防止轴承漏油是值得重视的。一、防止轴承漏油1.封油的结构和漏油的原因一般泵和风机等的轴承采用沟槽、密封圈、毡圈和几种型式的组合结构封油。炼油厂泵用轴承典型的封油结构如图1(国产DR型油泵)和图2(y型油泵)所示。通常,驱动端的轴承最易漏油,因为驱动端的轴承比非驱动端的大,而油池是公用的,如果液面高度对较小的轴承合适,则对较大的轴承就显得高了些,加上轴承的锁紧螺母和锁紧垫圈扰动润滑油而飞溅到轴承压盖内侧和轴上,使油沿轴封漏出(对非公用
Rotary equipment used in many industrial sectors, often bearing oil spills, it pollutes the environment, waste oil, the bearing fever, or burning bearings, bearing shaft, and even damaged some of the equipment brought seal, so that is sealed The flammable, explosive, toxic and other media leaks, the occurrence of fire or poisoning. Therefore, to prevent bearing oil spill is worthy of attention. First, to prevent oil leakage bearings 1. The structure of the oil seal and the reasons for oil leakage General pumps and fans and other bearings with grooves, seals, felt ring and several types of combination of structure seal oil. Refined oil pump pump typical oil seal structure shown in Figure 1 (domestic DR-type pump) and Figure 2 (y-type oil pump) shown. Normally, the bearings on the drive end are the most susceptible to oil leakage because the bearings on the drive end are larger than those on the non-drive end and the oil sump is common. If the fluid level is appropriate for smaller bearings, the larger bearings appear higher, Coupled with the bearing lock nut and lock washer disrupting the lubricant splashed to the inside and shaft of the bearing gland, so that the oil leak along the shaft seal (for non-public
