气动延时器是射流程序控制系统中一种重要装置,而阻容延时器是气动延时器的主要型式,如何提高它的计时精度是一个重要问题,至今仍研究不够。作者曾研制了一种阻容延时器。本文对这种延时器的结构和工作原理作了简单介绍,而着重对这种延时器的计时精度进行分析,从而对提高计时精度的可能性和措施提出一些看法。 The pneumatic delay is an important device in the jet program control system. The RC delay is the main type of the pneumatic delay, and how to improve its timing precision is an important issue, which is still not enough. The author has developed a RC delay. This article briefly introduces the structure and working principle of this delay, and emphatically analyzes the timing accuracy of such delay, so as to put forward some opinions on the possibility and measures to improve the timing accuracy.
