1.润滑油质量不高.由于质量不高,各项指标未达标,使润滑油变质的潜在因素.2.盛油用具不清洁.保管及使用中的各种盛油器具不清洁,未清洗就盛油,使杂质混入而变质.3.混入机械杂质.使用环境污染严重,灰尘及纤维多,各部零件正常运转时,相互摩擦、磨损的金属粉末等进入油中.这样使机械杂质就更多了.4.炭粒增高.特别是空压机、内燃机、柴油发电机等一些机械设备的气缸活塞工作部位温度较高,接触高温或燃烧气体,使油中的炭粒增多.5.环境污染.各种润滑油的工作环境和使用条件不同,在使用中产生炭素、油焦、酯类、皂类、以及油中添加剂的消耗而产生的氧化物等. 1. The quality of lubricating oil is not high.As the quality is not high, the indicators did not meet the standards, so that the potential deterioration of lubricants. 2. Oil equipment is not clean. Storage and use of a variety of oil cleaning equipment unclean, unwashed Oil, so impurities mixed and deteriorated .3 mixed with mechanical impurities. Use of serious environmental pollution, dust and fiber, the normal operation of various parts, friction, abrasion, and other metal powder into the oil.This makes the mechanical impurities even more More .4 carbon particles increased.Especially air compressors, internal combustion engines, diesel generators and some other mechanical equipment cylinder piston working temperature is high, contact with high temperature or combustion gases, the carbon particles in the oil increased .5 environment Pollution.A variety of lubricants working environment and the use of different conditions, the use of carbon, oil coke, esters, soaps, as well as the consumption of oil additives generated oxide.
