我公司运输处是以运输大型建筑构件为主的车队,拥有载重汽车、壁板拖车、拖车及吊车等共100余辆,其中70％以上是进口车辆。这些车辆的发动机都属于高速大功效的内燃机, 对其机油质量的要求很严,如果使用杂质含量过高油质已坏的机油将会造成发动机的加速磨损,甚至导致机械事故;如果这100余辆车每辆车每次都提前l000～2000km换油,那么每辆车一年按四次换油时间计算将浪费40万至80万车公里使用的机油,对能源和经济上的损失都是很可观的。为了提高对机械设备的科学管理,我们于1986年开展了机油快速化验工作。根据发动机的工况和润滑油的特性选择了酸值、斑点、污染度、粘度、水份等几个重要指标,作为对发
The transportation department of our company is a fleet consisting mainly of transporting large-scale building components. It has a total of more than 100 vehicles including trucks, slatted trailers, trailers and cranes, of which more than 70% are imported vehicles. The engines of these vehicles are all high-speed, high-efficiency internal combustion engines, and the quality of their oil is very strict. If the use of excessively high levels of impurities in the engine oil will cause the engine to wear out, or even cause mechanical accidents; if more than 100 Each vehicle shifts 1 000-2000 km in advance of each vehicle, so each vehicle will waste 400,000 to 800,000 vehicle-kilometres of engine oil per year by four oil-change times per year, both for energy and economic losses. Very impressive. In order to improve the scientific management of machinery and equipment, we launched a rapid test of oil in 1986. According to the operating conditions of the engine and the characteristics of the lubricating oil, several important indexes such as acid value, spot, pollution degree, viscosity and moisture were selected as the
