工程机械使用的油料种类有柴油、机油、液压油、液力传动油、齿轮油等。油料质量的好坏及清洁度直接影响工程机械的性能发挥及使用寿命。在工程机械的使用和管理中,油料的质量变差(如油料变质、含水分、杂质)、油料使用不当、操作人员对此不够重视,都会造成工程机械的严重磨损,导致工程机械出现早期故障。1工程机械用油的清洁保证工程机械用油的清洁要做到以下5点。1)加注油液必须经过沉淀、过滤在加油口设滤网,同时擦净加油口四周的尘土,及时盖严 Construction machinery used in the types of fuel diesel, oil, hydraulic oil, hydraulic transmission oil, gear oil. Quality and quality of oil and cleanliness directly affect the performance of construction machinery and service life. In the use and management of construction machinery, the deterioration of oil quality (such as deterioration of oil, moisture and impurities), improper use of oil materials and insufficient attention by operators will result in severe wear of construction machinery and lead to early failure of construction machinery . 1 construction machinery oil cleaning to ensure the construction machinery oil to achieve the following five points. 1) refueling fluid must be precipitated, filtered in the refueling port filter, while cleaning the refueling port around the dust, timely cover Yan
