我厂500 t快速挤压机经过改进使生产能力超过了设计水平。不仅挤压速度快、操作性能好,而且安全可靠。下面简介挤压机电控方面的改进情况。一、蓄势站高压水罐水位指示器的改进水位指示器由原来接触式的改为密封浮筒式(图1)。挤压机水罐水位共分五级控制,每一级水位包括两组舌簧管,每组由四只舌簧管并联组成(图1中只表示两只并联)。其工作原理是:在一个不导磁的不锈钢管内放置一
Our factory 500 t fast extrusion machine has been improved so that the production capacity of more than the design level. Not only extrusion speed, good performance, but also safe and reliable. The following describes the improvement of the extruder electrical control. First, the poise station high pressure water tank water level indicator to improve the water level indicator from the original contact to seal buoy (Figure 1). The water level of the extruder jug is divided into five levels. Each level of the water level consists of two reed tubes, each of which consists of four reed tubes connected in parallel (only two are shown in parallel in FIG. 1). Its working principle is: placed in a non-magnetic stainless steel tube
