一、Y81S—100手动金属打包液压机(见液压原理图) (一)操纵各缸,均无动作; 原因;系统(即高压)溢流阀⑩之调节手柄回松或处于故障开启状态,不能建立推动活塞运动的起码压力。 (二)操纵合益无动作: 原因;即使高压溢流阀正常,但中压溢流阀⑥之调节手柄回松或处于故障开启状态,合 First, the Y81S-100 manual metal hydraulic packaging machine (see Hydraulic Schematic) (A) the operation of each cylinder, no action; reason; system (that is, high pressure) relief valve ⑩ control handle back to loose or in the fault open state can not be established Piston exercise to promote the minimum pressure. (B) to manipulate the benefits of no action: the reason; even if the high-pressure relief valve normal, but the pressure relief valve ⑥ control handle back to loose or in the fault open state, and
