Teach you how to increase turbocharger rotor life
Most of the small-displacement cars now use the turbocharger rotor, which can relieve the excess pressure when the increased pressure exceeds, thereby increasing the life of the throttle body, but the unreasonable operation of the car owner will also reduce the The life of the turbocharger rotor, in order to reduce the car owner's cost, Botao Power Machinery will teach you how to increase the life of the turbocharger rotor.
1. Do not leave the car
After the car engine is started, especially in winter, it should be allowed to run at a high speed for a period of time, so as to allow the grease to fully lubricate the rolling bearing before the rotor of the supercharger motor runs at a high speed. Therefore, it is absolutely forbidden to slam the accelerator after just running to prevent damage to the supercharger sealing ring.
2. do not immediately turn off the engine
After the car engine runs at high speed for a long time, the engine should not be turned off immediately. When the car engine is working, a part of the car oil provides lubrication and cooling of the stator rolling bearing of the supercharger. After the running car engine is suddenly shut down, the oil pressure quickly drops to zero, the high temperature of the turbocharger part of the supercharger is introduced into the middle, and the heat in the rolling bearing support shell cannot be quickly taken away, and at the same time the supercharger The rotor of the motor is still running at high speed under the action of inertia. Therefore, if the car engine is suddenly turned off when it is hot, it will cause the car oil in the supercharger to overheat and damage the sliding bearing and shaft. In particular, avoid sudden engine shutdown after banging the accelerator pedal a few times.
3. Maintain cleanliness
When disassembling and assembling the turbocharger rotor, it is necessary to maintain cleanliness, and each tee joint must be blocked with a cleaning cloth to prevent dirt from falling into the turbocharger and damaging the motor rotor. When overhauling, pay attention not to impact and damage the centrifugal impeller. If the centrifugal impeller must be replaced, perform a dynamic balance test to solve it. After reassembly is complete, remove the blockage.
4. to carry out cleaning
Because the turbocharger rotor often runs at high temperature, its grease pipe is very easy to have a part of fouling due to the high temperature effect, which will lead to insufficient lubrication of the supercharger rolling bearing and damage. Therefore, the grease pipe needs to be cleaned after a period of operation.
5. pay attention to maintenance
Before delivery and after receiving the vehicle, the connection status of each pipe of the gas pipe should be checked to avoid loosening and falling off, which would cause the turbocharger rotor to be invalid and the gas short-circuit fault to enter the cylinder.
