润滑油、工业用油及相关产品（L级）-T系列（涡轮机） 涡轮机润滑油规范

[中文适用范围]： 本文件规定了交付时涡轮机润滑剂的最低要求。它旨在与 ISO 6743-5 结合使用。本文件规定了用于润滑大多数类型发电涡轮机的各种润滑剂的要求，包括蒸汽涡轮机、燃气涡轮机、带有公共润滑系统的单轴联合循环涡轮机和水力涡轮机。本文件未规定风力涡轮机润滑剂的要求，该要求在 ISO 12925-1 中涵盖。考虑以下润滑剂： - 矿物油，API 组 I、II、II+、III，包括来自 GTL（气转液）工艺的组 III，和 III+。一些 API 组 II 和 III 适用于高温燃气轮机； - 合成润滑剂、酯（API 组 V）和聚α烯烃（API 组 IV），用于高温燃气轮机； - 合成润滑剂、酯（API 组 V）和聚α烯烃（API 组 IV），可用于水力涡轮机，符合环境要求； — 耐火磷酸酯型润滑剂。 [外文原描述]： This document specifies the minimum requirements for lubricants for turbines, as delivered. It is intended to be used in conjunction with ISO 6743-5. This document specifies the requirements for a wide variety of lubricants for the lubrication of most types of turbines for power generation, including steam turbines, gas turbines, single shaft combined cycle turbines with common lubrication system and hydraulic turbines. This document does not specify the requirements for lubricants for wind turbines, which are covered in ISO 12925-1. The following lubricants are considered: — mineral oils, of either API groups I, II, II+, III, including group III from GTL (gas to liquid) process, and III+. Some API groups II and III are suitable for high temperature gas turbines; — synthetic lubricants, esters (API group V) and polyalphaolefins (API group IV), intended for high temperature gas turbines; — synthetic lubricants, esters (API group V) and polyalphaolefins (API group IV), environmentally acceptable for use in hydraulic turbines; — fire resistant phosphate-ester type lubricants.
