有人认为润滑工作很简单,润滑就是给机械设备加油,液体的油叫机油,半固体的油叫黄油,只知道有这两种油就行了,也有的认为价格高、进口的高级油脂总比国产的油脂好,代用作润滑准没问题。这两种倾向都是错误的,原因是对润滑工作缺乏了解,设备润滑必须做到“对症下药”,要根据具体情况研究选用合适的润滑材料,做到既不盲目选用高级润滑材料,又能使设备得到合理润滑。一、选用润滑材科的基本方法正确选用润滑材料首先要熟悉了解润滑材料品种、用途和质量等主要指标,然后,要了解机械设备的运动副工作温度、运动副精度、材质、硬度、运动位置方向、运动速度、负荷大小等。 Some people think that lubrication work is very simple, lubrication is to give machinery and equipment, liquid oil called oil, semisolid oil called butter, only know that there are two kinds of oil on the line, and some think the price is high, imported high-grade oil than domestic The grease is good, substitute for lubrication no problem. These two tendencies are wrong because the lack of understanding of lubrication work, equipment lubrication must be “right medicine”, according to the specific circumstances of the study choose the right lubricating material, so that neither blind selection of advanced lubricants, but also to make Equipment is properly lubricated. First, the selection of the basic method of lubrication materials Correct use of lubricants First of all be familiar with the lubrication materials to understand the variety, use and quality and other major indicators, and then, to understand the mechanical equipment, working temperature, vice, accuracy, material, hardness, Direction, speed, load size and so on.
