多功能真空装置在恒压过滤实验中的应用

摘要

A process of designing a reduced pressure vacuum control device , which was required by chemical engineering experiment based on Measurement of Constant Pressure Filtration Parameter , was introduced.The device can be used to the rotary evaporator experiment , and also be used to charge high boiling recovery liquid in a vacuum.Besides, it can ensure the continuity of the experiment.The device is widely used in a state of high utilization , the volume is so small to save the space of laboratory and the maintenance of it is convenient.It is adequate for teaching , research and other fields.It has been applied in chemical engineering experiment teaching reform.%介绍一种化工原理实验所需的，可用于恒压过滤参数测定以及旋转蒸发实验的减压真空控制装置。该真空控制装置适用于旋转蒸发实验，尤其在真空运行状态下收集高沸点的回收液，并能保证实验的连续性。该装置利用率高，体积小，节省实验室空间，而且维修方便、节省财力，适用于教学、科研等领域。当前已在化工原理实验教学改革中得到应用。
