10-500kN m Ram type Marine Electro-hydraulic Steering Gear
10-500kN m Ram type Marine Electro-hydraulic Steering Gear consists of one set of ram type driving mechanism, two sets of motor kinetic tank for oil pump and one oil box, which has simple structure to install and is widely used in navigation zone of inland rapid flowing river, normal navigation zone, and for sea ship. When it is used for navigation zone of inland rapid flowing river, the steering gear, specification below 16kn·m, is added an extra pressure accumulator or a set of manual emergency pump for emergency steering control; specification above 16kn·m, is added an extra set of DC motor pump unit for emergency, to comply with CCS rules. Control mode of marine electro-hydraulic steering gear series includes direct control of hand-operated direction valve, direct control of steering mechanism, electronic control, pump control and etc. Electronic and pump control can be used together with any form of autopilot and follow-up pilot.
