一、突出的问题我厂有各种减速器数百台。1978年以前,设备润滑情况不佳,突出的问题是漏油。φ400无缝管轧机组的1～5~#及5a 输料辊道漏油最为严重。这条辊道全长90米,由78组减速器组成。输送坯料温度为1150～1270℃,每小时输送70根次。在这种高温条件下,有的密封件老化变形,有的烤焦损坏,造成大量漏油。仅1977年,全年消耗机油竟达120吨。平均每月 First, the outstanding problems I plant a variety of reducer hundreds. Before 1978, equipment lubrication was not good, the outstanding problem was oil spill. φ400 seamless tube rolling mill 1 ~ 5 ~ # and 5a conveyor roller leakage is the most serious. This roller is 90 meters in length, composed of 78 sets of reducer. Transport billet temperature of 1150 ~ 1270 ℃, 70 times per hour delivery. In this high temperature conditions, some seals aging deformation, and some burnt damage, resulting in a large number of oil spills. In 1977 alone, the annual consumption of oil up to 120 tons.
