The electric-mechanical energy-hydraulic energy is converted by the pump driven by the motor. Oil pump and hydraulic motor complete. The pump body works by sealing the cavity so that its volume changes. The ideal pump does not exist, because there will always be product gaps on the structure, and the mechanical wear of the vertical disk injection molding machine will also produce gaps, so the efficiency of the pump must be considered. The quality of the oil pump is different, and its efficiency is different, which directly affects the stability of the hydraulic system. In addition, the compression performance of the oil also has an impact on the pump efficiency.

The hydraulic acceleration device is a device that converts the hydraulic energy into axial acceleration. The output speed of the shaft is controlled by oil pressure; The output speed of the shaft is controlled by the input flow.

Control components mainly refer to various control valves, such as pressure valves, directional valves, proportional valves, directional valves, etc. We produce injection molding machine, in addition to the back pressure through the attention of the relief valve to control, the rest of the pressure and flow control are controlled by the proportional pressure flow compound regulator, no flow valve. The direction control valve is a controller that controls the flow direction of the oil in the system, which is carried out according to the program of changing the direction of the movement of the actuator. The valves on the steering wheel are: conduit type, electro-hydraulic type and electro-hydraulic type.
