The invention provides a hydraulic system for controlling a controllable-pitch propeller, and belongs to the technical field of controllable-pitch propellers. The hydraulic system comprises an oil tank, a hydraulic pump set, a control assembly and a variable-pitch assembly. The control assembly comprises a three-position three-way reversing valve and a first two-position four-way reversing valve,and the variable-pitch assembly comprises a servo oil cylinder, a propeller hub oil cylinder and a first three-position four-way reversing valve. According to the hydraulic system for controlling thecontrollable-pitch propeller, the variable pitch of the controllable-pitch propeller can be controlled through a single pump, so that the investment and maintenance costs are reduced.
