Embodiment Construction
[0034] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0035] The invention provides an automatic oil string control device for a pitch control propeller, figure 1 It is a structural schematic diagram of an automatic oil spill control device for a controllable pitch propeller provided by an embodiment of the present invention. The automatic oil spill control device includes: a control module 100 , a forward solenoid valve 200 and a reverse solenoid valve 300 .
[0036] The control module 100 includes a controller 110 , a forward relay 120 and a reverse relay 130 . The controller 110 is used to obtain the pitch change time t required by the pitch control propeller from the maximum position of the pitch in the forward direction to the maximum position of the pitch in the reverse direction, a...

The invention discloses an automatic oil swapping control device and method for an adjustable pitch airscrew and belongs to the technical field of ship propulsion. The automatic oil swapping control device comprises a control module, an ahead solenoid valve and an astern solenoid valve. The control module comprises a controller, an ahead relay and an astern relay. The controller is used for obtaining the needed variable-pitch time t, from the maximum position of the screw pitch in the ahead direction to the maximum position of the screw pitch in the astern direction, of the adjustable pitch airscrew, and controlling a coil of the ahead relay and a coil of the astern relay to be sequentially powered according to the set time interval on the basis of the variable-pitch time t, a contactor ofthe ahead relay is connected with the coil of the ahead solenoid valve to control whether the ahead solenoid valve is powered or not, and a contactor of the astern relay is connected with the coil ofthe astern solenoid valve to control whether the astern solenoid valve is powered or not. According to the automatic oil swapping control device and method, a control button or handle in a control chamber does not need to be manually operated, and manpower is greatly saved accordingly.
Description
technical field [0001] The invention relates to the technical field of ship propulsion, in particular to an automatic oil string control device and control method for a pitch control propeller. Background technique [0002] The controllable pitch propeller propeller rotates the propeller blades through the driving mechanism in the propeller hub, and adjusts the pitch of different sizes to adapt to various working conditions in the motion of the ship. Before the installed adjustable-pitch propeller is put into use, it must be cleaned first, and then the normal commissioning of the entire system must be carried out. On the one hand, the oil string cleaning makes the hydraulic oil circulate in the system, carrying out the impurities in the system, and then the impurities carried by the circulating oil are filtered out through the system filter, and on the other hand, it can discharge the air in the system. [0003] During the oil stringing process of the controllable pitch pro...
