The invention discloses a hydraulic control device for adjustable pitch side thrusting of a ship. The hydraulic control device comprises a hydraulic station and a side thrusting pitch angle adjustment mechanism in a propeller hub, wherein the hydraulic station comprises a side thrusting oil tank, a motor pump unit, a filter, an electromagnetic overflow valve, a pressure compensator and an electromagnetic proportional reversing valve; an input end of the motor pump unit is connected with the side thrusting oil tank; a pipeline of a working branch at an output end of the motor pump unit passes through the filter and the pressure compensator, and is then connected with an input end of the electromagnetic proportional reversing valve; a pipeline of an oil return branch at the output end of the motor pump unit returns to the side thrusting oil tank via the electromagnetic overflow valve; a pipeline at an output end of the electromagnetic proportional reversing valve is butted with the side thrusting pitch angle adjustment mechanism in the propeller hub; the device can allow a working oil flow entering the electromagnetic proportional reversing valve to be more stable; when a pitch is adjusted, the pitch is changed accurately and stably; oily soil produced during working of the propeller hub is cleaned; the quality of working oil of a gear box in the propeller hub is ensured; and the hydraulic station is in a safe working state all the time.
Description
technical field [0001] The invention relates to a hydraulic control device for ship's adjustable pitch side thruster, in particular to a hydraulic control system for variable pitch side thruster. Background technique [0002] The lateral propulsion device that changes the thrust by adjusting the pitch of the blades is widely used in large and medium-sized civil transport ships. Because the magnitude of the thrust can be changed by changing the pitch angle, and the pitch angle can be changed continuously, it can improve the maneuverability of the ship. performance. At present, the adjustable pitch side thruster generally adopts a hydraulic system to complete the pitch adjustment. [0003] Common adjustable-pitch side thruster hydraulic systems include a gravity tank, and the oil in the gravity tank is supplied to the pitch control pump while providing sealing oil pressure to the side thruster gearbox. The installation height of the gravity oil tank of this type of hydraulic...
