Embodiment 1
[0040] see figure 1 , a hydraulic control system for a full-turn steering propeller, including a No. 1 balance valve 1, a No. 2 balance valve 2, a hydraulic motor 7, and a hydraulic brake 8. The No. 1 port 11 of the No. 1 balance valve 1 is connected to the No. 1 hydraulic motor. The working oil port 9 communicates, the No. 2 port 12 of the No. 1 balance valve 1 communicates with the hydraulic motor third working oil port 71 of the hydraulic motor 7, and the No. 3 port 21 of the No. 2 balance valve 2 communicates with the second hydraulic motor port 71 of the hydraulic motor. The working oil port 10 communicates, and the fourth port 22 of the second balance valve 2 communicates with the hydraulic motor fourth working oil port 72 of the hydraulic motor 7. There is a valve between the first balance valve 1 and the second balance valve 2 No. 1 damping hole 14, No. 2 damping hole 15, No. 1 bypass damping hole 16, No. 2 bypass damping hole 17, the No. 1 damping hole 14, No. 2 dampi...

The invention discloses a hydraulic control system of a full-rotation rudder propeller and a control method thereof. The hydraulic control system of the full-rotation rudder propeller comprises two balancing valves and two corresponding bypass damping holes, wherein two ends of each of the two bypass damping holes are correspondingly connected with a pilot control pressure channel of the corresponding balancing valve and a system overflow filling oil mouth. The control method comprises the steps that when the full-rotation rudder propeller rotates back, an outlet of one of the balance valves and the corresponding bypass damping hole will form a hydraulic half-bridge, high-pressure oil subjected to pressure dividing and filtering by the hydraulic half-bridge will act on the pilot control pressure channel of the other balancing valve to open the channel, and a back pressure is formed at the position of a working oil mouth of a hydraulic motor. According to the design, the system eliminates the phenomenon of vibration of full-rotation rudder paddle back rotation and improves operation comfort and reliability.
Description
technical field [0001] The invention belongs to the technical field of rotary hydraulic control, and in particular relates to a hydraulic control system and a control method of a full rotary rudder propeller, which can be applied to dynamic positioning engineering ships or platforms. Background technique [0002] The full-turn rudder and propeller device can provide omni-directional vector thrust, and is an important equipment for dynamic positioning engineering ships or platforms. Rotation is one of the most frequent actions in the working process of the full-turn rudder and propeller device, and the control of the slewing action adopts the driving method of hydraulic motor + reducer. When the rudder propeller rotates, the hydraulic control system drives the hydraulic motor to rotate, the hydraulic motor drives the reducer to rotate, the reducer drives the drive gear to rotate, and the drive gear drives the meshed slewing bearing inner ring gear to rotate, and finally reali...
