第六章 LUBE OIL SYSTEM 润滑油系统 6.1 GENERAL DESCRIPTION一般描述 The lube oil system supplies filtered lubricating oil to turbine engine bearings and various package components within operating pressure and temperature limits. The lube oil system is monitored by the package control system and incorporates lube oil reservoir, oil cooling system, pumps, filters, pressure control devices, and temperature control valves.润滑油系统过滤的润滑油供给透平引擎轴承及各种装置部件，以使之处于操作温度及压力限值之内。润滑油系统由装置控制系统监视，与润滑油存储罐、油冷却系统、泵、过滤器、压力控制设备及温度控制阀合为一体。 6.1.1 General Lubricating Oil Requirements一般润滑油要求 Lubricating oil containing suitable additives must meet physical and chemical requirements in Table 6.1.1. Lubricating oil shall not contain additives that are degradable below 284°F (140°C) or water separable. Additives shall remain uniformly distributed throughout the oil at all temperatures above pour point up to 284°F (140°C).包含有合适添加剂的润滑油必须满足表6.1.1的物理和化学要求。润滑油不应含在284华氏（140摄氏度）以下降解的添加剂及可分离水。当温度超过284华氏（140摄氏度）时，添加剂应该保持均匀分布到整个油体。 Table 6.1.1 General Lubricating Oil Physical and Chemical Requirements通用润滑油物理及化学要求 ASTM Std.美国材料试验协会标准 Oil Properties油属性 Minimum Requirements For New Oil新装油最低要求 D130 Copper Corrosion at 212 °F (100°C), three hours在212华氏（100摄氏度）铜腐蚀，3个小时 Class 1b 1b级 D665 Rust Prevention, Procedure B防锈，流程B Pass D892 Foam Limits, Milliliters Maximum泡沫限制，最大值的千分之一 Sequence 1 顺序1 Sequence 2 顺序2 Sequence 3 顺序3 50/0 50/0 50/0 D943 Oxidation Resistance, Minimum Number of Hours to 2.0 Neutralization Number抗氧化性，中和的最小时间 2000 D1401 Emulsion Test乳化测试 40-40-0 (30) D4628 Zinc, Weight %, Maximum锌占最大比重 0.005 D1744 Water, Weight, Parts Per Million, Maximum每一百万含水最大 200 (0.02 wt. %) D1947 Load Carrying Capacity, lb/in., Minimum载流容量 1000 D4172 Wear Preventative Characteristic, Scar Diameter, Millimeters Maximum (167°F [75°C] 1200 rpm, 88.1 lb [40kg], 1 hour)防磨耗特性，创伤直径，毫米最大 0.90 D2273 Sediment Volume % Maximum沉积物体积%最大 0.005 6.1.2 Petroleum Lubricating Oil润滑油 Petroleum lubricating oil ISO VG 32 (S150) is used on this in
