摘要
大量的实验研究表明气动元件流量特性参数的测定正确性受到很多因素的影响。测量方法、测量仪表的精度是比较明显的影响因素。此外,气动元件的内部结构、使用压力、气动元件内的流动状态的影响也不可忽视。该文阐述了使用压力对测量气动元件流量特性参数的各种方法产生的影响。
During a great deal of experimental studies, it is found that many factors impact on flow-rate characteristics of pneumatic components. Method of determinations and accuracy rank of equipments are main factors. Besides these apparent factors, structure of pneumatic components, pressure applied and flow conditions inside pneumatic components should not be ignored either. This paper focuses on the operating pressure effects on determination methods of pneumatic component flow-rate characteristics.
