Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing.

[0015] like figure 1 As shown, the redundant control valve group of the controllable pitch propeller hydraulic system of the present invention includes a triple pump group 1, a three-way ball valve 2, a high valve group filter 3, an electromagnetic overflow valve 4, an electro-hydraulic reversing valve 5, a double Connected filter 6, electromagnetic overflow valve 7, proportional valve 8, electro-hydraulic reversing valve 9.

[0016] The first pump, the second pump and the third pump in the triple pump group 1 are connected together through shafts. The first pump in the triple pump group 1 is connected to the high control valve group and the main control valve group respectively through the three-way ball valve 2, and the high control valve group and the main control valve group are respectively connected to the actuator cylinder of the control pitch propeller. When worki...

Abstract

The invention relates to a controllable-pitch propeller hydraulic system redundancy control valve unit, which comprises a high control valve unit, a main control valve unit and a triple pump set. A first pump in the triple pump set is respectively connected with the high control valve unit and the main control valve unit through a three-way ball valve, and the high control valve unit and the maincontrol valve unit are respectively connected with an actuator oil cylinder of a controllable-pitch propeller. During normal work, the three-way ball valve cuts off the connection between the first pump in the triple pump set and the high control valve unit, the first pump is used for supplying oil to the main control valve unit, and the main control valve unit controls the controllable-pitch propeller to act; when the main control valve unit fails, the three-way ball valve switches to enable the first pump in the triple pump set to communicate with the high control valve unit so as to controlthe controllable-pitch propeller to act. The existing triple pump set (the first pump) is utilized, a simple three-way ball valve loop is added, and thus redundancy of the main control valve unit isrealized; it is guaranteed that when the main control valve unit fails, the purpose of emergency control can be achieved by enabling the high control valve unit to control the controllable-pitch propeller to act.

Description

technical field [0001] The invention relates to a controllable pitch propeller hydraulic system of a ship power propulsion device, in particular to a redundant control valve group of the controllable pitch propeller hydraulic system. Background technique [0002] The controllable pitch propeller generally adopts the hydraulic system to adjust the blade pitch. The hydraulic system is controlled by the hydraulic pump and the reversing valve. When the main control valve group fails and the crew cannot enter the cabin for repair, the pitch control function of the controllable propeller Just can't realize, cause accident, seriously affect the safe operation of controllable pitch propeller system. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a redundant control valve group of the controllable pitch propeller hydraulic system, which can be used to solve the problem that the main control valve group of the contro...
