汽轮机油氧化安定性能的影响因素

Affecting Factors for Oxidation Stability of Turbine Oil

探讨了影响汽轮机油氧化安定性能的因素,指出基础油中的芳烃、胶质、碱性氮、硫化物等对汽轮机油的氧化安定性有不良的影响。为提高汽轮机油基础油对抗氧剂的感受性,应提高精制深度,深度脱除芳烃、胶质及氮化物,降低硫化物的含量。用加氢法生产的基础油,具有非常优异的抗氧化安定性,抗氧剂、金属减活剂的复合使用能够明显改善汽轮机油的氧化安定性能。

This paper discussed several factors affecting oxidation stability of turbine oil and found that the main factors are aromatics, colloid, alkali nitrogen and sulfide in base oil. In order to improve impressibility of the oil for antioxidant, it should be down that increasing refining extent, deeper removing aromatics, colloid, and nitride and decreasing sulfide content. The base oil produced by hydrogenating has very excellent antioxidation stability. The complex use of antioxidant and metal deactivator can obviously improve anti-oxidation stability of turbine oil.
