在一些机械化施工单位,国产机械与进口机械并存,工程机械与载重(自卸)汽车并用,机型、车型比较复杂,加上设备的新老交替,使润滑油(脂)、液压油及其它工作油的品种牌号,少则数十种,多则上百种。而当油料供应不足时,只好代用。这给油料管理(供应、储存、分发、回收、再生),机械的润滑保养与使用维护作业,带来了相当的困难。尤其在现场,因为缺乏用油常识,或者所需的油品缺货,错用或不合理代用的情况屡有发生。因为用油混
In some mechanized construction units, domestic machinery and imported machinery co-exist. Construction machinery is used in combination with load-carrying (dumping) vehicles. The models and models are more complicated, and the old and new equipment alternates to make lubricants, grease, hydraulic oil, and others. There are dozens of types of working oil, ranging from a few to hundreds. When the oil supply is insufficient, it is better to use it instead. This brings considerable difficulties to oil management (supply, storage, distribution, recycling, and regeneration), lubrication, maintenance, and maintenance of machinery. Especially at the scene, because of the lack of knowledge about oil, or the shortage of oil needed, there are frequent cases of misuse or unreasonable substitution. Because of oil mixing
