摘要
以VM4100高温黏度计和DM2000高温密度计搭建了最高实验温度为350℃的导热油黏度测量平台,并以其测定了T66和S750标准导热油样品及其混合液在不同温度区间的黏度值。T66和S750标准导热油样品的黏度测量误差分别为4.55%和3.90%,均在5%以内,表明VM4100高温黏度计可被用于导热油黏度的工程测量。对标准导热油样品实测黏度值进行了回归分析,拟合所得黏度-温度关系式计算误差在9%以内,计算精度较高,表明该关系式可用来预测高温导热油的黏度值。且以实验验证了导热油混合液黏度可按质量成分进行加权计算。
With the aid of a VM4100 high temperature viscometer and DM2000 high temperature densimeter,the viscosity measurement platform of heat transfer oil has been established,with the highest experimental temperature being 350℃.The measurement of viscosity values of standard heat conducting oil samples T66 and S750 and their mixed liquids in different temperature ranges thus can be achieved.The errors of viscosity measurement of standard thermal conductive oil samples of T66 and S750 are 4.55%and 3.90%,each less than 5%,which indicates that a VM4100 high temperature viscometer can be applied for the engineering measurement of thermal conductive oil viscosity.A regression analysis has been made of the measured viscosity value of the standard heat transfer oil sample,with the calculation error of the viscosity-temperature relationship being less than 9%.The relatively high calculation accuracy indicates that the formula can be used to predict the viscosity of heat transfer oil within high temperature range,and the experiment verifies the fact that the viscosity of the heat transfer oil mixture can be calculated by weight according to the mass composition.
