What Make Turbine Rotor Stuck

There are more and more cars with turbocharger in the market. The turbocharger can improve the intake of engine air. And so as to improve the power and torque of main engine. Cars are more dynamic. When drivers use these cars, they had better get more knowledge of turbocharger. The more the better.

Little people know why does the turbine rotor stuck. In fact, there are following factors that cause stuck. The oil pressure may be too low. If the joint of oil inlet pipe is loosen or leakage will make the turbine rotor and bushing stuck. So people should tighten the clamping sleeve and screw sleeve of pipe joint. Certainly drivers must change the oil and oil filter in time. Dirty oil will make the oil hole of bushing blockage. If drivers often start the engine emergency or stop engine suddenly, that also will make the turbine rotor stuck.

Compared to cars with normal engine which is in naturally aspirated engine, cars with turbocharger are in higher maintenance cost. Turbine driven by the exhaust gas has very high rotating speed while working. It needs oil with high quality to come true the lubrication and cooling.

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.

Choose A Suitable Bearing

Turbocharger is one of the important technology in the future automotive development. Compared to the naturally aspirated engine which with equal power, the turbocharger always own smaller displacement and lower oil consumption. It has a positive significance on energy saving and emission reduction. When the energy worked, there is a part of the oil supply of turbocharger rotor bearing lubrication and it also could used for cooling.

The running energy stopped suddenly and the oil pressure decreased to zero. The high temperature of turbocharger parts pass to the middle and the heat of bearing shell can not be took away quickly. At the same time, turbocharger rotor is still rotating in high speed with the effect of inertia. So it is easy to make the oil too hot and even damage the bearing if the energy stopped suddenly in heat state.

Turbocharger is composed by fixed nozzle ring, rotating impeller and turbine shell. Some small turbochargers are without nozzle ring because it could reduce the volume and weight, and even make its structure simple. This is called non turbine shell. Turbine impeller and the compressor working wheels shares one rotating shaft, the rotor is just composed by these three parts. With the high speed of the rotor, we muse check its dynamic balance and choose a suitable bearing type to ensure the turbocharger work successfully.

Solve Common Problems In Bearing House

Wear is the most common problem to bearing house. The traditional method to solve this problem is processing by welding machine to repair. Surfacing will make parts surface reach to high temperature and even make the part deformation or cracks. Nowadays we adopt polymer composite materials to repair it on site. There is not any limited to repair the thickness. Repairing in site can save a lot of downtime to manufacture and even create huge production.

The repairing process is very simple. At first, you should do some surface treatment. It means that you should remove grease and moisture from bearing house surface. Then reconcile repairing materials. Secondly, painting the material on the repair parts of the bearing house evenly and filled it strongly. After the material has been cured, you can heat its surface properly and accelerated material curing.

Generally speaking, bearing house wear can be repaired about three hours or even more, but it must be less than six hours. This operation usually easy to learn and don’t need any special equipment and professional training. While on site repairing has reduce the equipment repairing time and transportation cost.
