Forced lubrication system of supercharger

The utility model belongs to the field of engines, and particularly relates to a pressurizer forced lubrication system which comprises a pressurizer, an oil inlet pipeline, an oil return pipeline, anengine main engine oil pump and an electronic engine oil pump, the electronic oil pump is arranged on the oil inlet pipeline and comprises a shell and an impeller arranged in the shell, an annular circulation gap is formed between the impeller and the shell, the cross section area of the circulation gap is larger than the minimum circulation area of a pipeline of the supercharger forced lubrication system, and the oil return pipeline is communicated with an oil circulation channel of the engine; by adopting the electronic oil pump, the problems of dry grinding, high-temperature coking and thelike of a supercharger rotor system are avoided, the operation time of the electronic oil pump is shortened, and the service life of the electronic oil pump is prolonged. 本实用新型属于发动机领域，具体是一种增压器强制润滑系统，包括增压器，分别设置在增压器两端的进油管路和回油管路，
