Turbocharger Parts High Strength, Heat And Corrosion Resistance
Oct 23, 2017

The failure of turbocharger parts will reduce the turbocharger efficiency, increase the exhaust and reduce the output power. For example, bearing wear or ablation failure will produce friction, so that the rotor assembly speed slows down. At the same time, the bearing damage will also make the turbocharger rotor assembly blade friction casing, resulting in the rotor assembly speed reduction.

Turbocharger exhaust gas bypass valve failure or the valve calibration is incorrect, will lead to pressurization pressure too high or too low. In particular,Turbocharger Parts pressurization pressure too low will cause excessive smoke and power reduction; too much pressure will cause oil spills and even damage engines.

The supercharger is a motor-driven air pump or compressor that increases manifold pressure to force the oil-gas mixer into the cylinder. According to the principle of work, turbocharger can be divided into turbo supercharger and mechanical supercharger.

The turbocharger uses the engine exhaust gas inertia impulse to promote the turbine interior turbine, turbine and drive the coaxial impeller, impeller pressure sent by the air filter pipe sent to the air, so that pressurized into the cylinder. The increase of air pressure and density can make the fuel burn more fully,Turbocharger Parts increase the output power, and achieve the effect of reducing fuel consumption and energy saving.

The supercharger is a motor-driven air pump or compressor that increases manifold pressure to force the oil-gas mixer into the cylinder. According to the principle of work, turbocharger can be divided into turbo supercharger and mechanical supercharger.

By the impeller, vortex shell, middle shell, compressor shell, bearings and other major components. The vortex shell is connected with the engine exhaust pipe. The compressor shell is connected to the air duct, and the outlet is to the inlet pipe. The compressor impeller and the turbine support rotate at high speed on the floating bearing. Turbine with High-strength, heat-resisting, corrosion-resistant alloy steel close casting, and through the welding connection on the rotor shaft, compressor impeller for aluminum alloy castings, with nuts fixed on the rotor shaft.

In order to solve the problems of low speed torque and turbine hysteresis, the technology research and development of turbocharger industry mainly revolves around the electronic pressurization technology. Electronic booster is to use the motor instead of exhaust to promote the turbine rotation, can eliminate the turbo-pressurization of the general existence of the turbine hysteresis phenomenon, because the control of the motor more accurate. Electronic supercharger is not universal, because the work of the electronic supercharger needs voltage support, and now the car 12V voltage is not enough to meet the needs of electronic supercharger,Turbocharger Parts so the electronic turbocharging system and 48V system combination is the future development trend.
