Abstract

The invention relates to a sealing device of turbine pressurizing compressor, which comprises a middle case, a sealing ring base, a retaining oil spray disc, a retaining bearing, and an oil baffle plate between the retaining oil spray disc and the middle case. Wherein, the oil baffle plate, the middle case and the retaining bearing can form a stable sealing chamber; the oil baffle plate is mounted at the inclined surface of annular heave to limit the flowing shape of machine oil with resisting and dividing the machine oil; the case of retaining oil spray disc that connecting the oil container has a annular heave whose inner and outer sides have inclined surface to change the flowing direction; the sealing ring base has a guide groove; the guide groove and the retaining oil spray disc form a guide channel to guide the machine oil leaked from the movable sealing gap between the oil baffle plate and the retaining oil spray disc into the oil reflux cut of middle case. The invention can effectively reduce the oil leakage with wider market prospect.

Description

technical field [0001] The invention relates to a turbocharger compressor end sealing device, which belongs to the field of internal combustion engines. Background technique [0002] my country's turbocharger industry has formed a considerable scale after decades of development. As a new technology, the turbocharger has promoted the development of the internal combustion engine and improved the technical performance of the internal combustion engine. , Such as the forward and backward curved compressor impeller, mixed-flow turbine, the calculation of the three-dimensional flow field and the breakthrough of the turbine dynamometer equipment, etc., have opened up broad prospects for improving the performance of the turbocharger. Although the performance of the turbocharger has been rapidly improved, at present, the sealing problem of the turbocharger is still a weak link of the turbocharger, which is mainly manifested in the oil leakage when the turbocharger is running. How t...
