FIELD: engines and pumps. ^ SUBSTANCE: proposed electrohydraulic control system is designed to control the displacement speed of inertial load connected to the actuator hydraulic motor output in compliance with the preset displacement algorithm. The proposed system comprises a hydraulic tank, actuator hydraulic motor, control unit, speed setting unit, three-position hydraulic control valve, pumping unit representing non-adjustable drive motor and constant capacity pump. Note that, additionally, the system incorporates an overflow valve, throttling controlled electrically-driven hydraulic control valve, and hydraulic lock. Note also that the control unit incorporates additionally the throttling electrically-driven hydraulic control valve control stage. ^ EFFECT: higher reliability and specified power, optimum weight and size characteristics for mobile radars. |
