针对混合制冷剂等挥发性混合物粘度测量的需要，研制了一种新的适用于测量低沸点混合物粘度的旋转式毛细管粘度计。该新型粘度测量装置在压力容器内嵌入旋转式毛细管粘度计，将旋转法升液和压力容器承压结合起来，避免了传统密封型毛细管粘度计由于抽放气的升液方式而导致混合物成分的变化，可以实现在较高压力下循环测量挥发性混合物溶液的粘度。采用R22和R290对旋转式毛细管粘度计进行了标定，并用R410A对粘度计的测量精度和性能进行了评价，粘度测量值与文献值最大相对偏差为0?81％。

According to the need for viscosity measurement of refrigerant mixtures, a new rotatable capillary viscometer is developed and designed. It is adequate for the viscosity investigation of the low boiling point liquid mixtures. A rotatable capillary viscometer is embed-ded in a pressure vessel. It combines the rotation method and the pressure vessel to realize the continuous experiment and eliminates the error brought from the deflation, which can repeat the viscosity measurement of the low boiling point liquid mixtures in the high pressure. The rotatable capillary viscometer was calibrated by R22 and R290 and checked by R410A. According to the results, the relative deviation of the viscometer has been controlled to be less than 0. 81%.
