What are the precautions for using turbocharger accessories?
Since the turbocharger parts often work at high speed and high temperature, the temperature of the turbocharger exhaust gas turbine end is about 600 °C, and the turbocharger rotor rotates at a high speed of 832-1040r/min. Therefore, in order to ensure the normal operation of the turbocharger, The following points should be paid attention to when using:
Leave without getting in the car:
After the engine is started, especially in winter, it should be allowed to idle for a period of time to allow the lubricating oil to fully lubricate the bearings before the supercharger rotor runs at high speed. Therefore, do not slam the accelerator after starting to prevent damage to the supercharger oil seal.
Do not turn off the flame immediately:
After the engine runs at high speed for a long time, it cannot be turned off immediately. When the engine is working, a part of the oil is supplied to the turbocharger rotor bearing for lubrication and cooling. After the running engine suddenly stops, the oil pressure drops rapidly to zero, the high temperature of the turbo part of the supercharger is transmitted to the middle, the heat in the bearing support shell cannot be quickly taken away, and at the same time, the supercharger rotor is still rotating at a high speed under the action of inertia. Therefore, if the engine is stopped suddenly when the engine is hot, it will cause the oil retained in the turbocharger to overheat and damage the bearings and shafts. In particular, it is necessary to prevent the engine from suddenly turning off after a few kicks of the accelerator.
keep clean:
When disassembling the supercharger, keep it clean, and plug each pipe joint with a clean cloth to prevent debris from falling into the supercharger and damaging the rotor. During maintenance, care should be taken not to collide and damage the impeller. If the impeller needs to be replaced, it should be subjected to a dynamic balance test. After reassembly is complete, remove the blockage.
To clean:
Because the supercharger often runs at high temperature, its lubricating oil pipeline is prone to partial coking due to the high temperature, which will cause the turbocharger bearing to be damaged due to insufficient lubrication. Therefore, the lubricating oil line should be cleaned after a period of operation.
