The proposed novel structure of the flow control valve promises to attain improved controllability, reliability and efficiency of the hydraulic control units of heavy mobile machinery operating at high flow rates regimes.
The device is equipped with a digital control unit, hydraulic cooling system, two return oil tank, and the main dynamic hydraulic unit to control the sheet flow as well as control the imposed forces on the die.
When wheel rotation increases because of tire slippage or loss of traction, the control unit signals a hydraulic or electric modulator to regulate brake line pressure to forestall impending wheel lockup.
The Fletcher drilling experiment system consists of a set of sensors, a drill control unit, drill and hydraulic power pack.
Longest hydraulic retention time (HRT) was observed in the control unit.
Each control unit of the control system is equipped with one hydraulic support.
To meet these requirements a sensor-controlled sprayer was developed, consisting of a hydraulic system that was fitted with air induction nozzles, an ultrasonic sensor and a control unit with display and navigator keys.
E ME represents the efficiency of the hydraulic control system.
were controlled with a central control unit.
