标准摘要
[中文适用范围]: 本国际标准规定了通过叶片式液压泵的性能测定液压油钢对钢抗磨性能的程序。 它涵盖了一系列液压油,包括无水和水性液压油,适用于遇到高速滑动接触的应用,例如叶片泵中的接触。 对于HM和HV类矿物油以及HFD类耐火流体,该方法适用于ISO 3448[1]中规定的粘度等级ISO VG 32、ISO VG 46和ISO VG 68。 在不同规定条件下,该方法适用于 ISO 12922[3] 中规定的 HFA、HFB 和 HFC 类相同粘度等级的水性阻燃液压油。 注:低于 ISO VG 32 和高于 ISO VG 68 的粘度等级可以通过该技术进行测试,但需要不同的泵入口粘度条件,并且尚未得到广泛评估。 本国际标准仅限于规定的限值。 [外文原描述]: ISO 20763:2004 specifies procedures for the determination of steel-on-steel anti-wear properties of hydraulic fluids by means of performance in a vane-type hydraulic pump. ISO 20763:2004 covers a range of hydraulic fluids, both anhydrous and aqueous, intended for applications where high-speed sliding contacts, such as those found in a vane pump, are encountered. For mineral oils of categories HM and HV, and fire-resistant fluids of category HFD, the method is applicable to viscosity classes ISO VG 32, ISO VG 46 and ISO VG 68, as specified in ISO 3448. Under different specified conditions, the method is applicable to aqueous fire-resistant hydraulic fluids in categories HFA, HFB and HFC, as specified in ISO 12922, within the same viscosity classes.
