Abstract

A lubricating system is disclosed. The lubricating system includes: at least one first to-be-lubricated component, wherein an inlet of each of the at least one first to-be-lubricated component is connected with a first lubrication oil inlet pipe, and an outlet of the each of the at least one first to-be-lubricated component is connected with a first lubrication oil outlet pipe; and at least one second to-be-lubricated component, wherein an inlet of each of the second to-be-lubricated component is connected with a second lubrication oil inlet pipe, and an outlet of the each of the at least one second to-be-lubricated component is connected with a second lubrication oil outlet pipe. An operating pressure of the each of the at least one first to-be-lubricated component is different from a working pressure of the each of the at least one second to-be-lubricated component.
