摘要
PURPOSE: An apparatus for analyzing performance of a hydraulic valve is provided to check reliability of the hydraulic valve by testing the performance of the hydraulic valve while separating the hydraulic valve from a main steam line and a main water feeding line. CONSTITUTION: An apparatus for analyzing performance of a hydraulic valve includes a touch panel(10) for display information and a power feeding switch(20) for feeding power to a central control panel. A power lamp(30) is provided to display the supply of the driving power. An ampere meter(40) displays a SET value and a display value of DC current when a solenoid valve is disconnected. A PLC error lamp(50) is turned on/off when an error occurs in programmable logic controllers. An emergency lamp(60) is provided to notify a user of an emergency stop of the analyzing apparatus.
