Marine Hydraulic Steering Gear Introduce



Consists of one set of ram type driving mechanism, two sets of motor kinetic tank for oil pump, one oil box, which has simple structure to install and is wildely used in navigation zone of inland rapid flowing river, normal navigation zone, and for sea ship. When use 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,add an extra set of DC motor pump unit for emergency, to comply with CCS rules.

Control mode of this 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.

320-1000kN·m ram type electro-hydraulic steering gear (four cylinders with twin piston and one tiller type)The reciprocating and ram type electro-hydraulic steering gear series consists of two sets of reciprocating and ram type rudder mechanism, two sets of motor kinetic tank for oil pump, one reserve tank. Control mode, including electronic control, pump control, can be used together with any form of autopilot or follow-up pilot. To meet cunstomer's requirement, two sets of rudder mechanism, can be used together or separately. One of which fails to
 work, can be used separated to ensure normal work of steering control. It is widely used for ships with high safety performance such as large ship, oil tanker, liquefied-gas carrier, chemical tanker and etc.


cylinder type electro-hydraulic steering gear
Consists of one set of rudder mechanism with two piston type of cylinders, two sets of oil pump units, one reserve tank, one electric control station. To finish procedure of steering control, rotate steerting switch of solenold valve in wheel house, though steering mechanism controls hydraulic oil to cylinder
access, thereby rudder blades work. When power is failure, steering mechanism can be used to complete emergency steering control. It is widely used in navigation zone of inland rapid flowing river, normal zone, and for fishing vessel or small size if sightseeing lunch.

The linked cylinder type electro-hydraulic steering gear series consists of one set of rudder mechanism with two piston type of cylinders, two oil pump power units, one reserve tank. One set of emergency pumps, pressure accumulator or DC motor pump unit is added for using in navigation zone of inland rapid flowing river, to comply with CCS rules.
Control modes includes direct control of manual direction valve, electronic control, pump control, among which, electronic and pump control can be used together with any form of autopilot and follow-up pilot.



The linked cylinder type electro-hydraulic steering gear (four cylinder) consists of one rudder mechanism with four piston type of cylinder, two sets of motor kinetic tanker of oil pump, one reserve oil tank. Control modes, including electronic and pump control, can be used together with any form of autopilot and follow up pilot. Four cylinders can be used together or in couples. One of which fails to work, can be separated to ensure normal work of steering control. It is widely used for ships with high safety performance such as large ship, oil tanker, liquefied-gas carrier, chemical tanker and etc.



Rotary vane electro-hydraulic steering gear
Consists of one set of rotary vane type of rudder mechanism, two sets of motor units of oil pump, one reserve oil tank. It has features of firm structure, minimum space occupation, easy installation, which maximum rudder turning angle is ±65° .Its control modes, including electronic, pump control, can be used together with any form of autopilot and follow-up pilot. Rotary vane steering gear does make navigation through narrow straits safer, because of the vessel increased manoeurablity and improved control when docking.

The rotary vane principle also ensure a constant torque through the steering sequence, providing the steering gear with maximum power output, the unique technical solutions ensure very low noise and vibration level
The compact and simple design reduce weight and secures fact, easy installation of steering gear. The actuators are mounted directly on rudder stock, without necessary use of key, facilicating easier assembly and dismantling of rudder stock. The rudder torque is transmitted by hydraulic coupling or by expansion rings.


synchronous steering gear
In order to meet the requirements of special ships on the steering gear, after special research and test, produce a type steering gear can overcome two rudder inner and outer resistance difference, in the whole operating process in synchronized state, a synchronous servo mechanism that the connecting rod does not need; the synchronous state same as us a connecting rod and avoids the defects by connecting rod. The electric hydraulic control synchronous servo, performance than the previous control synchronization is much superior; applicable to catamaran, wide boat.

The synchronous steering gear can accept autopilot control, such as asynchronous steering, can have state of same direction with asynchronous and different direction with asynchronous manipulation. Can instead azimuth thruster function. Can be used in the marine engineering ship tugboat, catamaran, dynamic positioning.

Synchronous steering gear has 24V electric operation, steering handwheel operation and emergency steering handwheel three ways. By a set of hydraulic pump station to provide power to drive the four cylinders two steering gear.
