在老水压机改造中,提高水压机挤压速度的控制精度是很重要的。它不仅可以提高挤压产品的成品率和生产率,还可以大大降低操作工人的劳动强度。我厂有几台老水压机都是用手动来控制挤压速度,控制精度低,工人劳动强度大。经我们不断探索,用滑阀式节流和电液伺服系统做为挤压速度控制的执行系统,在使用中得到了比较理想的效果。此系统的主要特点是结构简单、操作方便、控制灵敏可靠。
In the transformation of the old hydraulic press, hydraulic press extrusion speed control accuracy is very important. It can not only improve the yield and productivity of extruded products, but also greatly reduce the labor intensity of operating workers. I plant a few old hydraulic press are manually to control the extrusion speed, low control accuracy, labor intensity. As we continue to explore, with the spool valve throttling and electro-hydraulic servo system as extrusion speed control system, in use has been the ideal result. The main features of this system is simple structure, easy operation, sensitive and reliable control.
