摘　　要：冶金工厂配套的液压系统往往需要配备独立的循环过滤冷却装置,对循环油泵流量的选择如何能够合理有效的配置,是保证系统介质工作温度高效控制及系统可靠稳定运行的一个重要环节。该文主要根据系统的发热及冷却散热功率推导出简便快捷计算循环油泵流量的公式,并对循环过滤冷却装置及主要元件配置的特点进行了论述,具体涉及了油箱有效容积、循环油泵安全阀、冷却水阀、循环过滤器等相关影响因素。Hydraulic system of metallurgical factories often require filtration cycle cooling device equipped with independent, how to recy- cle pump flow selection can be a reasonable and effective configuration which is an important link of guarantee system of medium and high working temperature control system that can be reliable and stable operation.According to heating and cooling power system derived conve- nient calculation of circulation pump flow formula which base on practical experience of circulation cooling device filtering characteristics and main component configuration are discussed, in particular to factors affecting effective volume of tank, circulating pump safety valve, cooling water valve loop filter, etc.
