Abstract

The invention discloses a centrifugal oil-gas separator. The centrifugal oil-gas separator comprises a shell, a cavity partition plate, a rotating shaft and a driving disc, wherein the cavity partition plate and the shell are used for forming a separation cavity in a separated mode, a sleeve pipe is arranged on the cavity partition plate, the lower end of the rotating shaft penetrates through thesleeve and then is connected with the driving disc, and a step-shaped gap seal is arranged between the upper end of the driving disc and the lower end of the sleeve. The centrifugal oil-gas separatorhas the beneficial effects that the step-shaped gap seal is directly adopted, compared with an original maze seal and an original fan and horizontal clearance seal combination, parts are reduced, theproduction is facilitated, the installation is simple and convenient, and the manufacturing cost is saved; and due to the facts that the path of the whole gap seal is long and the structure of the gapseal is a step-shaped structure, oil needs to pass through two upward climbing processes when the oil in a driving chamber enters the gap again, and the horizontal step surface can also play a role in reducing pressure and buffering the incoming oil, so that the oil in the driving chamber is also not prone to entering the separation cavity.

Description

technical field [0001] The invention relates to the technical field of oil-gas separation, in particular to a centrifugal oil-gas separator used for oil-gas separation in a crankcase of a vehicle engine and an engine used therein. Background technique [0002] At present, there are two kinds of sealing structures in the centrifugal oil-gas separator. A kind of prior art publication number is CN101189414A, the name is used for the device (10) that is used for purifying gas while pumping gas to crankcase is disclosed by the device for purifying gas while pumping gas to crankcase, The device (10) comprises: a housing (12) with a separation chamber (14) inside, a rotor structure with a rotor shaft (32) and a centrifugal rotor (39), the rotor shaft (32) is rotatably Mounted in said housing, the centrifugal rotor (39) is located in the separation chamber (14), and - fluid drive means (64) for driving the rotor shaft (32) by means of a drive fluid, said drive means (64) is arrang...
