多年来,我们对国内部分大中型水电站作了一些调查,现就润滑油系统存在的几个问题予以探讨,以供参考。 (一)润滑油的劣化与回收问题 水电站润滑油常用透平油(汽轮机油)、机械油及空压机油。其中用量最大的是透平油,除用于润滑外,还用于操作。大中型水电站用油量,一般达数十吨到数百吨乃至上千吨。石油是国家的重要战略物资,也是不可缺少的化工原料。原油中含润滑成分不过10～17％,提炼工艺复杂,而且在加工过程中损失达一半左右。我国生产润滑油的成本,通常为原油的10倍左右(有的甚至高达20—30倍)。因此减少油耗、节约用油,具有十分重要的政治和经济意义。 水电站用油一是要防止有形的浪费,如漏掉(有一电站环形接力器漏油,严重时一天达百余斤)、倒掉(使用后不沉降净化重复使用)、烧掉(有的“废油”实则未废,往
Over the years, we conducted some surveys on some large and medium hydropower stations in our country. We will discuss some problems existing in the lubricating oil system for your reference. (A) the deterioration and recovery of lubricating oil Hydropower Station lubricants commonly used turbine oil (turbine oil), mechanical oil and air compressor oil. One of the most important is the use of turbine oil, in addition to lubrication, but also for operation. Large and medium-sized hydropower station with oil, usually up to tens of tons to hundreds of tons and even thousands of tons. Oil is an important national strategic material, but also an indispensable chemical raw materials. Crude oil containing lubricating composition, but 10 to 17%, the extraction process is complex, and in the process of loss of up to about half. The cost of producing lubricants in our country is usually about 10 times that of crude oil (some even up to 20-30 times). Therefore, reducing fuel consumption and saving oil have very important political and economic significance. First, to prevent visible waste of hydropower stations, such as missing (such as a leakage of a power plant ring relay, a day when the seriousness of up to 100 jin), drained (after use does not sedimentation purification reuse), burn (some “ Waste oil ”actually not waste, to
