设计并研制了一种新型的磁力循环泵,具有密封性能良好且能够长时问稳定工作的特点,可以应用于较广阔温区的汽液相平衡试验中。该磁力循环泵采用外部磁力驱动方式,避免了流体的热污染和化学污染。因此该磁力循环泵可以为汽液相平衡试验系统中的汽相或者液相循环提供动力,是整个系统的关键部件之一。
A magnetic driven recirculation pump was designed and developed. With good seal design, it can be used in a wide temperature range and can work stably for a long time. Driven by an external magnet and without any heat and chemical pollution to the fluid, the pump can be used to drive the vapor or liquid phase in the recireulation loop for the vapor-liquid equilibria experiments.
