PRESSURE CONTROL DEVICE FOR HYDRIC PUMP UNIT

摘要

PURPOSE: A pressure control apparatus of a hydro pump unit is provided to prevent a safety accident by easily and accurately controlling pressure which is actually required. CONSTITUTION: A pressure control apparatus of a hydro pump unit includes a manometer(210), an input flow rate control valve(220), and an output flow rate control valve(230). The input flow rate control valve is installed in one side of the manometer and controls a flow rate of an input side while being connected to the hydro pump unit in series through a connection hose. The output flow rate control valve is installed in the other side of the manometer and creates an oil pressure drop by discharging hydraulic oil flowing in through the input flow rate control valve.
