为考察液压油的氧化耐久性能,设计建立了Vickers 20VQ5高压叶片泵台架系统及液压油氧化耐久性评定方法,在高温、高压下进行空气夹带试验。考察油品黏度变化、酸值增加和油泥生成情况。参比油实验表明,台架运行平稳,能较好地区分不同液压油品氧化耐久性能和油泥生成趋势,满足长寿命液压油新产品开发的试验评定需求。
為攷察液壓油的氧化耐久性能,設計建立瞭Vickers 20VQ5高壓葉片泵檯架繫統及液壓油氧化耐久性評定方法,在高溫、高壓下進行空氣夾帶試驗。攷察油品黏度變化、痠值增加和油泥生成情況。參比油實驗錶明,檯架運行平穩,能較好地區分不同液壓油品氧化耐久性能和油泥生成趨勢,滿足長壽命液壓油新產品開髮的試驗評定需求。

To study the oxidation durability of hydraulic oils,the Vickers 20VQ5 high pressure vane pump test-bed system and hydraulic oil oxidation durability evaluation method were designed to do air entrainment test under high temperature and high pressure.The situation of oil viscosity,acid value increase and sludge formation was investigated.Reference oil experiment showed that the bench system keeps smooth operation,and can be used to distinguish different hydraulic oil oxidation durability and sludge formation trend,and can meet the testing and evaluation requirements of the development of long-lived hydraulic oil new products.
