Changzhou pressure guide impeller extends service life

In order to ensure the service life of the turbocharger, lubrication and cooling of the floating bearings of the turbocharger should be ensured in the design. At the same time, during use, it is required to: ① After starting the engine, it should idle for 3-5 minutes and not immediately increase the load to ensure good lubrication of the turbocharger. The main reason is that the turbocharger is located at the top of the engine. If the turbocharger starts running at high speed immediately after the engine starts, it will cause the oil pressure to not increase in time to supply oil to the turbocharger, resulting in oil shortage and damage to the turbocharger, and even burning the entire turbocharger The idle time should not be too long, generally not exceeding 10 minutes. Excessive idle time can easily cause oil leakage at the compressor end Before parking, do not immediately shut down the engine. Idle for 3-5 minutes to lower the speed of the turbocharger and the temperature of the exhaust system, and prevent malfunctions such as reheating, oil coking, and bearing burning. Frequent incorrect use can damage the turbocharger An engine that has not been used for a long time (usually more than 7 days), or an engine with a new turbocharger, should be filled with oil at the inlet of the turbocharger before use. Otherwise, poor lubrication may reduce the service life or damage the turbocharger Regularly check whether there is any looseness, air leakage, or oil leakage in each connection part, and whether the return oil pipe is unobstructed. Otherwise, it should be promptly eliminated Ensure that the air filter is clean and replace it regularly as required. ⑦ Regularly replace the engine oil and oil filter. ⑧ Regularly check the radial and axial clearance of the turbocharger shaft, and the axial clearance should not exceed 0.15 millimeters. The radial clearance is: the clearance between the impeller and the pressure shell should not be less than 0.10 millimeters. Otherwise, professional personnel should be hired for repair to avoid expanding the loss
