钢液真空精炼系统的抽真空设备通常采用多级串联的蒸汽喷射真空泵。由于蒸汽喷射泵具有运行所需蒸汽与冷却水耗量大的缺点,导致生产运营成本很高,因此节能型水环泵替代多级串联蒸汽喷射泵最后一级蒸汽喷射泵在钢液真空精炼领域中的应用越来越普遍。本文深入探讨了泵口吸入绝对压力、理论气量、实际气量和叶轮转速等因素对水环泵选型的影响,并对如何避免真空泵系统停泵过程中水环泵产生振动与噪音和如何循环利用水环泵工作液提出了解决措施。
Vacuum pumping equipment for vacuum refining system usually adopts multistage steam jet vacuum pump. As the steam jet pump has the operation required steam and cooling water consumption disadvantages, resulting in high production and operation costs, energy saving water ring pump instead of multi-stage series steam jet pump last level steam jet pump in the field of molten steel vacuum refining The application of more and more common. This paper discusses in depth the influence of inlet suction absolute pressure, theoretical volume, actual volume of gas and impeller speed on the selection of water ring pumps and how to avoid the vibration and noise of water ring pumps and how to recycle them during the pump stoppage Water ring pump working solution proposed solutions.
