Key Part To Turbocharger

The key part of turbocharger bearing which is named of lubrication type. It is also called full floating bearing. This bearing is in high working speed and with bad working environment. So ensure lubrication is very important.

Low oil pressure can lead suppling slowly and turbocharger will be in failure. It will not make such failures occur if the energy started normally. Oil supply will be slow when the energy stated at first time after changing the oil. At the same time, the bearing will be lack of oil lubricated. At this condition, you should idle running for about three minutes after starting. Certainly you could not improve the running quickly. While you also could not stop the energy suddenly on the highway or uphill. You must make the energy running for about one minute in order to prevent shorten oil to the turbocharger bearing. So drivers must obey the rule of manufacturers instructions. At the same time, you should be careful to oil quality.

In fact turbocharger is an air compressor. It increase the air intake quantity by compressed air. Sports cars which take part in the competition are usually equipped with turbocharger on the engine. That can make the car burst out more power. Energy is rely on the fuel combustion in the cylinder to generate power.

The entered fuel is limited by amount of air which sucked into the cylinder. You can only increase the output power from compressing more air if the energy has been in the best statue. And even improve combustion performance ability. Turbocharger is an only mechanical device that increase the output power under the same work efficiency.

Exhaust turbocharger Spare Parts

Exhaust turbocharger can improve the power of the engin by the energy of exhaust. Turbocharger can increase the power and torque without increasing engine output. The maximum power output of engine with turbocharger could be increased 40 percent and even more. At the same time, it also can improve the fuel economy and reduce exhaust emissions.

Exhaust turbocharger spare parts are mainly about centrifugal compressor, radial turbine and intermediates.

Centrifugal compressor is composed of intake population, compressor impeller, the compressor, compressor back cover and other parts. The compressor inlet is connected with the air filter through the hose, runoff turbocharger are mostly use the axial air intake type and the air resistance is small. Inlet is generally made by aluminum alloy casting. It can reduce the air resistance. Certainly the inlet surface must be machined. The annular space formed by the gap between the compressor and compressor back cove is known as compressor diffuser. Compressor impeller is consist of blades, wheel hub, wheel disc and wheel cover. Compressor impeller made by aluminum alloy casting and use  nut  fixed on the rotor shaft. The volute collect the air from diffuser pipe and lead air to the compressor outlet.

The turbine is a device that change exhaust energy into mechanical energy. Radial turbine are made from the vortex shell, turbine and the airway. Gas turbine blade and disk are cast into integration by precision method. The shape of the blade generally use a parabolic or general two times curve. Turbine work under the impact of  high temperature,high speed and corrosive gas. So its material must be in high strength, high temperature resistance and corrosion resistance.
