New full-rotation rudder propeller hydraulic servo system

Abstract

The invention discloses a novel hydraulic servo system of a full-rotating rudder propeller. The novel hydraulic servo system of the full-rotating rudder propeller comprises a motor pump assembly, and the motor pump assembly comprises a first motor and a closed type variable displacement piston pump, and the first motor is connected with the closed type variable displacement piston pump; an oil port of the closed type variable displacement piston pump is connected with an oil port of a first diversion valve block, a first diversion port of the first diversion valve block is connected with a first control end of a first rotating motor, a second diversion port of the first diversion valve block is connected with a first control end of a second rotating motor, and a second control end of the first rotating motor and a second control end of the second rotating motor are connected with a diversion port of a second diversion valve block; the motor drives the closed type variable displacement piston pump to supply power oil and drives the first rotating motor and the second rotting motor to rotate a support pipe of the propeller to achieve rudder rotating. The hydraulic servo system of the full-rotating rudder propeller has the advantages that work is reliable, the noise is reduced, and the power range is widened.

Description

technical field [0001] The invention relates to the technical field of ship hydraulic servo, in particular to a novel full-rotation rudder propeller hydraulic servo system. Background technique [0002] The original full-turn propeller control hydraulic system adopts an open loop control system, that is, the pump source is responsible for providing pressure oil, and an electro-hydraulic proportional directional valve is installed on the circuit, and the electro-hydraulic proportional directional valve is controlled by electrical signals. Thereby realizing the control of the rotation speed, direction and position of the rudder propeller device. The open system has the following problems in the actual use process: [0003] 1. The system is not compact, which causes a great waste of space in the ship's warehouse; [0004] 2. The system is complex, the efficiency is low, and the system generates serious heat; [0005] 3. The repeatability of the system control is low; [000...
