一、保压(2Y、5Y1、7Y1、9Y0通电)：
1、 Voltage maintaining (2Y, 5y1, 7y1, 9y0 are energized)
由于一次性餐具设备的注入缸对模腔内的熔料实行保压并补塑，因此只要少量油液，所以泵1卸载，泵2单独供油，多余的油液经溢流阀4回油箱，保压压力由远程调压阀19调节。
As the injection cylinder of disposable tableware equipment maintains pressure and replenishes the molten material in the mold cavity, only a small amount of oil is needed. Therefore, pump 1 is unloaded and pump 2 is supplied with oil separately. The surplus oil is returned to the oil tank through overflow valve 4, and the pressure maintaining pressure is regulated by remote pressure regulating valve 19.
