低压铸造机控温系统的改进

Reforming of temperature controlling system for die-casting machine

通过对SR70A系列仪表及固态继电器的功能、特性介绍 ,揭示了SR70A系列PID调节仪及固态继电器的鲜明优点。将SR70A系列PID调节仪与固态继电器相接合 ,设计出一种实用的过零调功温控系统 ,用于PLUME低压铸造机 ,控温精度和速度显著提高 。

The functions and characteristics of SR70A series PID controller and solid-state-relay are introduced, showing the excellence of these instruments. Through combination of the SR70A and solid-state-relay, a very practical temperature controlling system for PLUME was designed. As a result, the control precision and speed was remarkably improved, and the casting defects connected with the temperature were obviously reduced.
