　　液壓油大致可以分為HL抗氧防銹液壓油、HM抗磨液壓油、抗燃液壓油、清凈液壓油和環境相容性液壓油。

　　抗磨液壓油又可分為:鋅型、無鋅行、無灰型。鋅型抗磨液壓油指的是該液壓油的抗磨劑主要為二烷基二硫代磷酸鋅（ZDDP），這種液壓油在葉片泵試驗中有很好的抗磨效果，但在高壓柱塞泵中會對銅柱塞產生嚴重磨損，研究人員認為是ZDDP熱分解造成的。為解決這些問題，對ZDD進行了改進，開發了穩定型ZDDP抗磨液壓油，及無鋅型、無灰型抗磨液壓油。后兩種抗磨液壓油主要使用S/P型極壓抗磨劑，在熱穩定性、水解安全定性上更優于ZDDP型抗磨液壓油，并且更符合環保要求。Hydraulic oil can be roughly divided into HL Antioxidation antirust hydraulic oil, HM Antiwear hydraulic oil, fire-resistant hydraulic oil, clean hydraulic oil and environmental compatibility hydraulic oil. Anti-wear hydraulic oil can be divided into: zinc, zinc-free line, ash-free. Zinc-type anti-wear hydraulic oil means that the main anti-wear agent of the hydraulic oil is zinc dialkyl dithiophosphate (ZDDP) , however, in high-pressure piston pump copper piston will produce serious wear, the researchers believe that ZDDP caused by thermal decomposition. In order to solve these problems, ZDD was improved and ZDDP anti-wear hydraulic oil was developed. ZDDP anti-wear hydraulic oil was zinc-free and ash-free. The latter two antiwear hydraulic oils mainly use s/P type extreme pressure antiwear agent, which is better than ZDDP type antiwear hydraulic oil in thermal stability and hydrolytic safety.
