Abstract

The invention discloses a novel turbocharger which adopts a magnetic bearing and solves the problems of bearing quality and oil-gas sealing effect of the existing supercharger. A supercharger module structure is provided with a magnetic bearing part arranged between a compressor stage throughflow element and a turbine stage throughflow element; and a compressor impeller of a compression air part in the compressor stage throughflow element is axially connected with a power turbine in the turbine stage throughflow element through a magnetic bearing, the compressor stage throughflow element and the turbine stage throughflow element respectively form a self circulating sealed pipeline to seal the self gas; and the magnetic bearing part is connected with a power supply system, a control systemmodule is connected with the power supply system and the magnetic bearing part, and the power supply system is connected with an energy storage and starting system. The novel turbocharger has the advantages of simplifying the supercharger structure and the sealing system, improving the reliability, reducing the mechanical machining difficulty of the supercharger and being propitious to environmentprotection and safe running.

Description

technical field

[0001] The invention relates to a turbocharger, in particular to a novel turbocharger. Background technique

[0002] With the development of my country's transportation industry, the load of internal combustion engines has increased, and the faults of turbochargers have also increased sharply. The faults of existing turbochargers are mainly concentrated in oil seal leakage, bearing burning, and rotor solidification. It accounts for 60% to 70% of the total failure rate of the turbocharger, and the bearing burning failure accounts for about 50% of the total failure rate of the turbocharger. The cause of bearing burning can be summarized into three factors: oil product, oil pressure and bearing quality, and the first two items are related to the oil lubrication structure; in addition, due to the use of oil lubrication, the oil and gas seal cannot provide a good seal for the moving parts Effect, causing oil seal leakage or carbon deposit solid death.
