Turbocharged And Mechanical Supercharged For Engine

Although turbocharger can make the power output easily. You still need to treat the high heat that produced by turbocharger carefully. The high heat has two effects. One is the oil which is responsible for cooling and lubrication directly. It will be oxidation quickly with the high heat. So turbocharger must choose good oil which is resistant high temperature and oxidation.

Another affected by high temperature is cooling system. It is in the air inlet part. In order to adding the oxygen content of the intake. Cars who own turbocharger are mostly increasing the charge air cooler. That could decrease the temperature of compressed air. At the same time, the cooling water tank and connection temperature regulator can all be appropriate to increase and improve the radiating efficiency. So I have nearly hear about that the turbocharger difficult to dissipate heat.

Compared to the turbocharged cars, the supercharged cars are much simpler. In principle, as long as the engine is running, the mechanical supercharger will produced naturally. More higher engine speed, more greater degree of pressure. The advantage of supercharged cars is without any hysteresis phenomenon. Acceleration feeling is quite linearized and has little difference with naturally aspirated engine. But the disadvantage of the supercharged one is driven by the belt.

Knowledge About Bearing Housing

Cap and base of the split bearing housing could be separated. It is mainly fit for spherical roller bearings and self-aligning ball bearing which with cylindrical and conical bore. This bearing housing is widely used in metallurgy, mining, transportation system, environmental protection equipment and so on. The main difference between various types are loading and sealing method. A good bearing housing always own good thermal conductivity and easy to be installing and removing. So it improved sealing efficiency greatly.

Sliding bearing housing is composed of upper cover, base, split bearing shell and mounting bolt. Bearing shell surface does not bear the load. And there is oil tank in it. Lubricating oil run into the gap through oil the hole and oil groove.

Various types of spherical ball bearing are composed of outer spherical ball bearings and spherical bearing. It is unnecessary to design bearing box when using. So the size is usually small and the structure is simple. Certainly it is convenient to using. Bearing housing has automatic aligning function. Bearing housing which adopt double sealing type is mainly applied to agricultural machinery, construction equipment, conveyor system, textile machinery and other processing equipment.

Method For Improving Compressor Housing Crack

Compressor housing often leads to parts crack or fracture phenomenon because of the defects of casting and machining, the internal stress and overload operation. Once the crack happen, you must take reasonable methods. The common repair method is using welding. But some parts material may be cast iron, aluminum alloy or titanium alloy, these are all difficult to do the welding processing.

Some dangerous occasions which are easy to explosion had better not adopt welding repair method. The new cold welding technology can avoid thermal stress and deformation. At the same time, the material usually own good adhesion and comprehensive performance of compressive strength, and corrosion resistance. So that this new technology can satisfy the requirement for compressor housing in the maximum. It can ensure effective operation at the inputs with lowest cost.

Compressor is mainly based on welding and brush plating spray. But both of them exist some defects. Thermal stress generated by the high temperature of repair welding can not be eliminated completely. On the contrary, it is easy to cause material damage and even lead to bend and break. Brush plating is limited by coating thickness, it is easy to peeling.
