【Abstract】 The large homemade CPP device and main diesel engine of a 9000 HP ocean salvage drag ship is briefly introduced in the paper. The hydraulic system of CPP and the circuits of main engine remote control system are described. It is indicated that the engine-propeller combined control in accordance with the preprogram of the correspondence between the setting pitches of CPP and the revolutions of main engine with the control method of equal toque limit and equal thermal load is reasonable. It is also suggested that lower pressure be adopted in the pneumatic control system of main diesel engine.更多还原
