Abstract
The utility model belongs to the technical field of aviation fuel systems, particularly relates to a split fuel pump, which comprises a pump body and a pump core which is arranged in the pump body, wherein a residual oil cavity is formed between the pump body and the pump core, a ventilation component is arranged above the outer side of the pump core, and an oil extraction component is arranged below the pump core. The split fuel pump is simple in structure, and can be achieved just by adding the ventilation component and the oil extraction component on a common split fuel pump. The split fuel pump is simple in structure, convenient to use and excellent in oil extraction effect. The split fuel pump can discharge residual oil in the pump core by changing the pump core, thereby preventing surrounding components and environment from being polluted by fuel, and reducing maintenance workload and maintenance time.
