One of the liquid as the working medium, usually mineral oil, its role and mechanical transmission of the belts, chains and gears and other transmission components are similar. Hydraulic transmission has many outstanding advantages, it is widely used, such as general industrial plastic processing machinery, pressure machinery, machine tools; walking machines in the engineering machinery, construction machinery, agricultural machinery, automobiles, etc.;; power plant turbine speed control devices, nuclear power plants, etc.; the ships deck with a crane (winch), the bow doors, bulkhead valve, stern thrusters, etc.; special technology with a huge antenna control unit, measuring buoys, lift revolving stage, etc.; military industrial control devices used in artillery, ship roll stabilization devices, aircraft simulation, The retractable landing gear and rudder control devices installed. Therefore, the overall design of hydraulic servo workstations, both to consolidate the basic knowledge learned, but also training students in basic skills.
