Hydraulic Tank

Hydraulic Pump

Control Valve

Actuator

1.Outline of Hyd. System: the equipment to transmit the power by oil flow

-Hydraulic Tank : Oil Storage

-Hyd. Pump : Create oil flow to transmit the power

-Control Valve : Direction control of actuator

-Actuator : Working device such as cylinder,motor and etc

Cylinder - Inline movement

Motor – Rotating movement

-Charecteristic of hydraulic oil : incompressible,automatic lubrication,less friction loss, higher

cooling efficiency,more safety for overload,silent operation,precise control
