Abstract
The paper goes to research on calculation to design the pneumatic system to reply electric-electrolic system for remote control of ship’s propeller pitch. The pneumatic system that replaces the electric-electronic system must ensure full control feature and pitch propeller indicator as the remote control system of propeller pitch by using electric-electrolic system. The alternative pneumatic system has overcome the disadvantages of electric-electronic systems being applied on ships. The disadvantage of the remote control system of propeller pitch by using electric-electrolic system is that the operation is less accurate in environments with high temperature, humidity, strong vibration environment on ships. The pneumatic system has the advantages of being safe, reliable and durable, with low installation cost. The system can operate in all environmental conditions and bad weather on ship.
