第一部分 概述

Chapter One General Introductions

1．术语Terminology

◆ 粘度：液体受外力作用移动时，液体分子间产生内摩擦力的性质，称为粘度。

◆ Viscosity：Flow of a fluid under external force，inner friction between molecular called viscosity.

◆ 运动粘度：指在某一恒定温度下，测定一定体积的液体在重力下流过一个标定好的玻璃毛细管粘度计的时间，粘度计的毛细管常数与流动时间的乘积，即为该温度下测定液体的运动粘度。在温度t时运动粘度用符号Vt表示。

◆ Kinematic viscosity: Under a given hydrostatic temperature, test the time which a fixed volume of fluid flow through glass capillary viscometer, the product of capillary coefficient and flow time namely the liquid kinematic viscosity under the temperature. “Vt” stands for viscosity at“t”temperature.

◆ 动力粘度：某温度下运动粘度和同温度下液体的密度之积为该温度下液体的动力粘度。在温度t时的动力粘度用符号ηt表示。

◆ Dynamic viscosity: under the same temperature, the product of kinematic viscosity and liquid density is the dynamic viscosity, it is indicates by the symbol “ηt”.

◆ 意义：粘度是绝缘油的重要指标之一，使用于变压器的绝缘油，在不影响油品其他指标（如闪点）的前提下，粘度尽可能的低一些为好，因为粘度越低，变压器的循环冷却效果越好；同时粘度也是润滑油的最重要指标之一，因为润滑油的牌号大部分是以油品标准中的运动粘度的平均值来区分的，另外正确的选择一定粘度的润滑油，可保证发电机和汽轮机组稳定可靠的运行状态，粘度过大或过小都会改变发动机的功率，增大燃料的消耗，增加机器磨损等；

◆ Significance: viscosity is one of important index of insulating oil, the viscosity of the transformer insulating oil should as lower as possible, because the lower viscosity, the better circulating cooling effects of transformer; meanwhile, it is one of important index of lubricant oil, the number of lubricant oil generally distinguished by the average of kinematic viscosity，in addition, proper choose of viscosity of lubricant oil will guarantee stable running of generator and turbine sets, viscosity is too higher or lower will change the power of generator, increase fuel consumption and wear etc.
