Embodiment Construction
[0013] The accompanying drawings non-restrictively disclose the specific structure of the embodiment of the present invention and its working process in the marine hydraulic station.
[0014] The marine hydraulic station mainly includes an oil storage tank 9, a motor pump unit 1, a safety valve 3, a main reversing valve 6 and a cooler 2. During operation, the motor pump unit 1 supplies the hydraulic oil in the oil storage tank 9 to the main reversing valve 6 The oil port P of the main reversing valve 6 sends the hydraulic oil to the hub, and the return oil enters the oil return line from the main reversing valve 6 port T, and the hydraulic oil is cooled by the cooler 2 in the oil return line. Generally, a safety valve 3 and a pressure regulating and overflow valve 8 are also provided in the marine hydraulic station. In order to realize automatic circulation cooling, the present invention sets up a hydraulically controlled reversing valve 4 in the marine hydraulic station.

The invention relates to a ship hydraulic station capable of realizing automatic cycle cooling, comprising an oil storage tank, a motor pump unit, a safety valve, a main reversing valve and a cooler, wherein the cooler is arranged in an oil return pipeline. The ship hydraulic station is characterized in that the oil port P and the oil port T of the main reversing valve are respectively connected with a high-pressure oil supplying pipe and the oil return pipeline, the oil port A and the oil port B of the main reversing valve are respectively connected with corresponding two-way oil supplying pipes, one of the two-way oil supplying pipes is connected with an inner oil pipe inside a stern shaft, and the other two-way oil supplying pipe is connected with an outer oil pipe of the stern shaft. Furthermore, a hydraulic operated directional valve is arranged between the high-pressure oil supplying pipe and the oil return pipeline which are connected with the oil port P and the oil port T of the main reversing valve, the oil inlet of the hydraulic operated directional valve is connected with the high-pressure oil supplying pipe, the oil outlet of the hydraulic operated directional valve is connected with the oil return pipeline, a shuttle valve is arranged between the two two-way oil supplying pipes connected with the oil port A and the oil port B of the main reversing valve, and an output hydraulic signal of the shuttle valve is a control signal of the hydraulic operated directional valve.
Description
technical field [0001] The invention relates to a marine hydraulic station, in particular to a marine hydraulic station realizing automatic circulation cooling. Background technique [0002] The marine hydraulic station is an indispensable and important part of the control part of the adjustable pitch propeller. When the adjustable pitch propeller performs pitch control operation, the hydraulic station outputs pressure oil to the working mechanism. However, most of the time, the controllable pitch propeller The pitch does not need to be adjusted, and the hydraulic station is in an idling state. At present, the hydraulic station with cooling device is to install an oil cooler in the oil return pipeline, and the oil returned by the system passes through the cooler to realize oil cooling. Without oil return, the cooler here does not work. In order to reduce the oil temperature in the oil tank, it is often necessary to configure an independent cooling system composed of a speci...
