随着气动门定位器节能技术的发,先导式电磁在些工业生产中广泛使用,先导式电磁的工作原理由电磁铁对气路首先进行控制,从而产生先导压力,之后主芯受到先导压力推动而发生动作。其具有制作成本低、耗能低、节能高的特点。本文对气动门定位器节能技术发进行了分析,其中对先导式电磁的应用进行了探讨。 Pneumatic door positioner with the energy-saving technology, the pilot-based electromagnetic widely used in some industrial production, the working principle of the pilot-style electromagnetic solenoid to the gas path first to control, resulting in pilot pressure, after the main core pressure by the pilot And action. It has the characteristics of low production cost, low energy consumption and high energy-saving. This paper analyzes the energy-saving technology of pneumatic door positioner, in which the application of pilot electromagnetic is discussed.
