我国仿制的液控大型管咀式挤压机,是用以挤压实心或空心的瓷介电阻制品的专用设备。也适用于冶金、陶瓷工业中压制成型制件。原机的液控系统(图1)比较复杂,操纵手柄较多,使用,调整与维修不便。因此,在满足使用要求的前提下,结合我国液压元件的市场供货情况,对该机液控系统进 Our imitation of the large liquid-controlled nozzle Tsui extruder is used to squeeze solid or hollow porcelain resistance products of special equipment. Also applies to metallurgy, ceramic industry in the suppression of molding parts. The original machine’s hydraulic control system (Figure 1) is more complicated, more joystick, use, adjustment and maintenance inconvenience. Therefore, to meet the requirements of the premise, combined with China’s hydraulic components market availability, the aircraft hydraulic control system into
