从注塑机液压系统看容积节流调速回路的使用

A View on the Application of Volume Throttling Speed Control Circuit by Hydraulic System of Plasticizing Machine

从某注塑机液压系统温升过高的原因分析,总结了限压式变量泵和节流阀(调速阀)组成的容积节流调速回路的使用范围。

By analyzing the causes of excessive temperature rise of the hydraulic system in a certain plasticizing machine, the paper discusses the application range of the volume throttling speed control circuit consisting of limited pressure variable pump and throttling (speed control) valve.
