The power unit or receiver for remote control system is not required since the hydraulic pump is controlled by electric signal. hydraulic cylinder. Easy adaptability to classification societies Steering gear can be easily complied with specification of tanker over than 10. The adoption of Mitsubishi Janney pump ( a variable delivery pump ) with an integrated servo controller of higher pressure and longer life has enabled the design of high pressurization and durable steering gear. the emergency generator can be designed just that much smaller in capacity. The local steering can be performed by pushing manually the push rod of solenoid valve. Steering gear is constructed with all pipings completed in the factory. The local steering can be performed by mechanical handle on the servo mechanism on the pump. requiring only a simple installation work on the ship. The rudder angle deviation signal from the steering stand operates the solenoid valve and controls the direction of oil from fixed displacement pump. ¯ 3 .000GT by changing the valve block. Trouble free Adoption of pump The maximum durability and reliability are guaranteed as steering gear. Fixed displacement vane type Hydraulic pump. Easy installation Maintenance free The power unit of remote control system is not required since the hydraulic pump is controlled by electric signal. C Series [ Valve Control S/G ] The electric rudder command signal is compared with the feedback signal of actual rudder angle in the steering stand. Each joint portion is provided with oil-impregnated metal to facilitate maintenance. are especially of sturdy construction and full consideration is given to safety. No-load motor start up Since the motor of the hydraulic pump can be started in the No-load condition. Complete dual control The control system is made to meet ABS and other classification societies rule requirements within the limit of the standard system design specification. The rudder angle deviation signal from the steering stand is amplified by the amplifier and controls electrically the stroke of variable displacement type pump through torque motor.

After a single failure as described above. 4 ¯ INFORMATION OF YOOWON INDUSTRIES LTD. the low oil level detector of the oil tank connected to the power system in operation is actuated to send an alarm to the bridge and engine room. And the power system in line with the malfunctioning piping system is stopped automatically by the second low level detector. 4. speed or below 7 knots. At the same time. 2. the rudder actuator capacity is reduced to half to designcapacity. At the same time. the rudder actuator has a total capacity (torque) equivalent to 100% of design capacity and the power system is completely doubled. Valve adjustment of A~ F on the next page diagram is then done manually in the steering gear room in order to isolate the malfunctioning hydraulic system. steering capability is maintained. In both 1-ram 2-cylinder and 2-ram 4-cylinder types. the related isolation valve also returns to its original position. steering capacity is maintained.000 GT tankers. 3. when a single failure accompanying oil leakage occurs in the piping system. It is necessary to reduce ship speed to half of max. by the low oil level detector of the oil tank connected to the power system in operation. When a single failure accompanying oil leakage occurs in the piping system. . In that case. Changing valves A and B to automatic isolation valves satisfies IMO regulation for over 10. the circuit isolation valves of both circuits actuate to isolate the malfunctioning piping system automatically.In this manner.
