The invention discloses a single-pump dual-rail fuel oil supply system. The single-pump dual-rail fuel oil supply system comprises a high-pressure oil pump which is driven by a servo motor to provide high-pressure fuel oil; the oil outlet end of the high-pressure oil pump is connected with at least two oil supply branches, wherein an electromagnetic flow regulating valve and a pressure accumulator for storing the high-pressure fuel oil are connected in series on each oil supply branch, and the output end of each oil supply branch is correspondingly connected to a corresponding fuel oil injector for injecting the high-pressure fuel oil to the combustion chamber of an engine; the single-pump dual-rail fuel oil supply system is characterized in that the high-pressure oil pump and the corresponding servo motor are connected with a plurality of pressure accumulators and a plurality of electromagnetic flow regulating valves so as to provide the desired fuel oil amount for a plurality of burners correspondingly, and the light weight requirement of the fuel oil supply system is met; the actual oil injection amount of the oil injector is detected by use of a flow sensor, and the rotating speed of the servo motor and the opening of the flow regulating valves are controlled by use of an electric control unit, so that the fuel oil amount of a plurality of oil paths reaches a set value; the system is simple in structure and low in energy consumption.
Description
technical field [0001] The invention belongs to the field of fuel supply systems, and in particular relates to a single-pump dual-rail fuel supply system. Background technique [0002] The burner is a device that mixes air and fuel in an appropriate proportion through a premixing device to make them fully combustible. Take the Stirling engine as an example: the Stirling engine is a closed-cycle reciprocating piston heat engine with external combustion , which is different from an internal combustion engine that relies on the combustion of fuel inside the engine to obtain power. The Stirling engine uses gas as the working medium. The fuel burns continuously in the combustion chamber outside the cylinder, and is transmitted to the working medium through the heater. The working medium does not directly participate in the combustion and is not replaced. The heater expands the gas when it is heated, and compresses it when it is cooled. Power is generated to drive the piston, and...
