Problems solved by technology

When the turbocharger surges, the air flow at the outlet of the compressor will vibrate strongly, causing the blades to vibrate strongly and generate a lot of noise, and the pressure at the outlet will drop significantly, accompanied by large fluctuations, even Will cause damage to parts

Abstract

The invention discloses a pressure impeller with non-uniformly distributed blades. The pressure impeller comprises a pressure impeller body, a plurality of large blades and a plurality of small blades; the plurality of large blades and the plurality of small blades are arranged on the pressure impeller body; the plurality of large blades and the plurality of small blades are uniformly distributed along the circumferential direction; the large blades and the small blades are arranged separately; the included angles between every small blade and the two adjacent large blades in the circumferential direction are not equal. Accordingly, the structure is simple and reasonable, the gas flow state when the pressure impeller runs at the surge operating point can be improved, and the purpose of surge inhibition can be achieved.

Description

technical field [0001] The invention relates to the technical field of turbochargers, in particular to a pressure impeller with unevenly distributed blades. Background technique [0002] A turbocharger is a machine widely used in engines. It compresses the air to increase the intake air volume of the engine, thereby improving the combustion of the engine, improving thermal efficiency and increasing the output power torque of the engine. The impeller of the turbocharger is the key part that acts directly on the air for compression. [0003] Due to the complexity of engine working conditions, there are still some problems in the application of turbochargers, and surge is a typical representative of them. When the turbocharger surges, the air flow at the outlet of the compressor will vibrate strongly, causing the blades to vibrate strongly and generate a lot of noise, and the pressure at the outlet will drop significantly, accompanied by large fluctuations, even Will cause da...
