PROPULSION CONTROL SYSTEM OF VARIABLE-PITCH PROPELLER VESSEL

摘要

PROBLEM TO BE SOLVED: To provide a propulsion control system of a variable-pitch propeller vessel in which a blade angle of propeller blades can freely be changed as necessary at any time.;SOLUTION: The propulsion control system 1 of a variable-pitch propeller vessel is equipped with a variable-pitch propeller 2; and a controller 3, into which a revolution signal from a tachometer 18, for detecting the revolutions of a main engine E, and a pressure signal from a pressure gauge 19, for detecting the pressure of hydraulic oil used for changing the blade angle of the variable-pitch propeller 2, are input, and which reduces the revolutions of the main engine E from the revolutions at a time when the pressure of the hydraulic oil detected by the pressure gauge 19 exceeds the threshold value.;COPYRIGHT: (C)2010,JPO&INPIT
