Points for replacing the turbocharger of diesel generator set

Technical common sense——
1. Clean the engine and replace the filter element. Drain the dirty oil, add 70% diesel and 30% engine oil to the engine, start the engine to run for 3 to 5 minutes to clean the engine and oil passage, and then let it go. Add an appropriate amount of engine oil and let it run after 5-10 minutes. Replace the oil filter element and air filter element, and then filter and add clean lubricant to the full scale of the oil scale, so as to ensure that the engine lubricant and oil passage are clean.
2. Check the turbocharger. Check whether the new turbocharger model is compatible with the engine. Turning the turbocharger rotor by hand should run freely. If the impeller stalls or there is a feeling of rubbing against the casing, find out the reason before installing.
3. Check if there is any debris in the compressor's intake line and the exhaust line in front of the turbine to prevent the debris from damaging the impeller.
4. Check the inlet and return lines of the booster. The inlet and return pipes of the turbocharger should be clean, and the inlet and return pipes must not be twisted and blocked. If a gasket is used for the inlet and outlet of the turbocharger, check the gasket for corrosion and deformation. The gasket cannot block the inlet and outlet.
5. Pre-lubricated booster. The supercharger is installed on the engine and is not connected to the oil pipe for the time being. First, add clean oil into the supercharger from the supercharger oil inlet, and turn the rotor by hand to make the supercharger bearing full of lubricant before connecting the oil pipe. .
6. Test run. Start the diesel engine, the oil inlet of the turbocharger must show the oil pressure within 3 ~ 4s to prevent the turbocharger bearing system from being damaged due to lack of lubricant. Run for 2min, check whether the rotor rotates smoothly and without noise, and then stop. Observe whether the rotor can run smoothly by inertia. Normally, it stops after about half a minute.
8. When the engine is running under load, the oil pressure must be between 196 and 392kPa to be safe. When idling, the oil pressure should not be lower than 70kPa.
9. The exhaust back pressure after the turbine and the pressure drop of the air filter must not exceed 4.9kPa. The air filter element should be protected from moisture, because the wet filter element will significantly increase the pressure drop.
