摘要
为进一步精确等静压生产工艺过程中高压密闭容器内温度变化的控制,提升温等静压工艺精度,结合导热油在温等静压工艺生产使用中升压时温度上升、泄压时温度下降以及工艺过程中的不均匀温度场等现象开展实验研究,从导热油的可压缩性角度出发对导热油进行研究。分析了导热油因压力变化造成密度变化而导致温度变化的形成机理与规律,结合理论和数据分析对导热油温度随压力变化的关系式进行推导,通过开展不同升压速率以及不同初始温度的实验验证了关系式的有效性。该关系式可用于温等静压高压密闭容器的温度计算。
In order to further precise isostatic pressure production process in the high-pressure closed container tem perature change control,improve the temperature isostatic pressure process accuracy,this paper combines the thermal oil in the temperature isostatic pressure process production use of temperature rise when the pressure,pressure relief when the temperature falls and the uneven temperature field in the process of the phenomenon to carry out experimental research,from the point of view of the compressibility of the thermal oil on the heat transfer oil research.The formation mechanism and law of temperature change due to density change caused by pressure change of heat transfer oil are analyzed,and the relationship between temperature change of heat transfer oil and pressure change is derived by com bining theoretical and data analysis,and the validity of the relationship is verified by carrying out experiments with different pressurization rates and different initial temperatures.The relationship can be used for temperature calculation of warm isostatic pressure high-pressure closed container.
