The invention discloses a hydraulic operation system of an aircraft refueling truck, an emergency refueling method and the aircraft refueling truck. The hydraulic operation system comprises an operation execution part, an oil tank, a control valve and an oil pumping assembly. The operation executing part comprises a fixed part and a movable part reciprocating relative to the fixed part, and an operation oil cavity is formed between the fixed part and the movable part. The oil tank communicates with the operation oil cavity. The control valve is used for controlling connection or disconnection of an oil way between the oil tank and the operation oil cavity. The oil pumping assembly comprises an oil pumping part and at least two driving parts, the oil pumping part acts on the oil inlet path, the driving parts operate independently, and when the control valve is in the on state, any driving part drives the oil pumping part to operate, so that hydraulic oil in the oil tank is pumped into the operation oil cavity to drive the movable part of the operation execution part to move. The hydraulic operation system provided by the invention is high in operation reliability, can assist the aircraft refueling truck in smoothly completing aircraft refueling operation, and ensures stable operation of an airport.
