在转动机械中,特别是转速较高的水泵和风机的轴承均采用机油润滑。机油润滑有散热快、润滑好的优点,但轴承的密封很难安装严密,我们采用过多种方法,如在轴上加装挡油环,或在轴承端盖上安装抽风管等措施,都不能消除轴封的漏油。(一)漏油原因转动机械轴承端盖上都装有油封,刚新装的油封与轴接触严密,油可能不会漏出或漏得少些,但运行 In the rotating machinery, especially the higher speed pumps and fans bearings are used oil lubrication. Oil lubrication has the advantages of fast heat dissipation and good lubrication, but bearing sealing is difficult to install tight, we have used many methods, such as the installation of the oil retaining ring on the shaft, or install the exhaust pipe and other measures on the end cap, Can not eliminate the seal leakage. (A) causes of oil leakage Rotating mechanical bearings are equipped with oil seals on the end cap, just the newly installed oil seal and shaft in close contact with the oil may not leak or drain less, but the operation
