Hydraulic Power Unit

We are offering hydraulic power unit. Hydraulic power unit (hpu) is used as oil installations, which through external piping system is connected with a number of hydraulic cylinders to control multiple sets of valve movement. Tank, pump and accumulator to form an independent power source of oil closed system. Filling stations can be equipped with plc control system, which controls all internal functions and generates a signal with a hydraulic control chamber (dcs) switching. The hydraulic servo valve control element is mounted directly on the hydraulic cylinder, through the valve into the high pressure hydraulic cylinder, pressure oil discharged from one of, or. Under normal, pump oil to the system to automatically maintain system rated pressure, through the control valve atresia, to achieve the valve functions to secure his position in any location; in working condition, hydraulic actuators controlled by a solenoid valve, the system command signal the solenoid valve action, control and accumulator hydraulic energy release, and then control slide valve cylinder, valve driven by mechanical transmission mechanism, the implementation of fast close, open and close properly and test control. High pressure cylinder can be fixed on the stem, but also directly as the executing agency with. Returns excess hydraulic oil hydraulic oil station, this pipeline system with a single return pipe inlet pipe valve can control several parallel connections. This has a special hydraulic drive technology is used to control the operation of the main steam valve actuators and turbine bypass system.
