ZY10-4自动液控增压器是一种新型的液压动力元件(图1)。它以一定功率的液体压力能为原动力,连续产生二次压力输出,适用于工作肘具有短期大负载及小位移特点的液压系统中,广泛使用在压榨机,校正机、试压设备、金属成形及塑料机械的液压系统中。采用增压器后,使系统工作更合理可靠,并显著节约能源。到1981年底,已有 ZY10-4 automatic pilot supercharger is a new type of hydraulic power components (Figure 1). It is a certain power of liquid pressure can be used as the driving force, continuous secondary pressure output for elbow with short-term load and small displacement characteristics of the hydraulic system, widely used in the press, calibration machines, pressure test equipment, metal forming And plastic machinery in the hydraulic system. The use of supercharger, make the system more reasonable and reliable, and significant energy savings. By the end of 1981, already
