Description
Technical Field
[0001] The utility model relates to the technical field of turbochargers, in particular to a wear-resistant turbocharger. Background Art
[0002] A turbocharger is a device that can increase the pressure of a gas or liquid medium, also known as a turbocharger or turbine unit. The working principle of a turbocharger is to use high-speed rotating turbine blades to accelerate low-speed, low-pressure gas or liquid medium and increase its pressure. The use of a turbocharger can increase the power density of the engine, improve the efficiency of the engine, and reduce exhaust emissions.
[0003] The Chinese authorized announcement number is CN219754657U, which is a wear-resistant turbocharger. The device uses materials optimization, surface treatment, coating and other technologies to make the turbine and impeller have higher hardness and wear resistance. The wear-resistant turbocharger can better maintain the gap between the impeller and the turbine, improve the supercharging efficiency, and the device has a longer service life, providing stable supercharging performance for the device for a longer time, reducing the frequency of replacement and reducing the cost of use. However, this patent still has certain shortcomings when used. If the oil is not changed for a long time or the air filter fails, too much dust will enter the supercharger, the floating bearing will be seriously worn, resulting in excessive bearing clearance and unstable oil film. When driving at high speed, the supercharger will soon become unbalanced, the vibration of the rotor shaft system will intensify, and the seals at both ends will be damaged, causing lubricating oil leakage. Therefore, we propose an anti-wear turbocharger to improve the above problems. Utility Model Content
