6. Maintenance of the oil seal plate Check the cracks, surface roughness and deformation of the oil seal plate. 7. When the sealing ring is running in the turbocharger, the sealing ring directly has thousands of friction with the relevant moving parts, which will inevitably cause wear. If it is not disassembled, it can still be reliably sealed due to the mutual friction and good coordination. After removal, the thickness of the seal ring can be measured to check for wear. Put the new seal ring into the groove, if the gap exceeds 0.23mm, the oil seal sleeve should be scrapped. The floating bearing retaining ring is a vulnerable seal, and needs to be replaced once it is removed. 8. Air compressor impeller maintenance Air compressor impeller is composed of blade, hub, wheel and wheel cover. When it rotates, the air is compressed under the action of centrifugal force and thrown to the edge of the working wheel

The bearings of turbochargers are usually floating bearings or rolling bearings. High speed turbochargers use floating bearings with high reliability. There is a certain gap between the floating bearing and the rotor journal and the middle housing. In the turbocharger operation, the rotor shaft and floating bearings are all floating in the lubricating oil, and there is no mechanical friction between each other. The lubrication between the rotor shaft and the bearing of the compressor adopts pressure lubrication, and the lubricating oil comes from the rich oil channel of the engine, filtered through the fine filter, and enters the middle housing of the supercharger. If the oil is dirty or deteriorated in use, the floating bearing is not easy to form an oil film, the bearing is easy to be scratched in semi-dry friction, and even overheating causes the bearing to deform or turn blue. If it is scratched, deformed or blue after disassembly, it needs to be replaced. During the inspection, if

Recently, there are often fan messages about turbocharged engines: I heard that turbocharged to about 100,000 kilometers is prone to problems, is this true? How long does it last? Is the maintenance cost high? Today, Tencent, the car to talk about the life of the turbocharged engine. In fact, for the turbocharged engine, the life of the engine itself is relatively long, here is mainly talking about the turbocharged system, this system because of high temperature and high pressure work, so the life of the early product is slightly shorter than the life of the engine part, generally 80,000 to 100,000 kilometers! At present, turbine technology is very mature, so if used and maintained properly, it can basically reach the same life as the engine! The turbocharger is a high-temperature component because the gas that drives it comes directly from the cylinder

The "2016 Internal Combustion Engine Supercharger Industry Development Forum" sponsored by the Engineering Research Center of Internal Combustion Engine Supercharger Technology was held in Beijing Institute of Technology on January 11, 2016. More than 20 representatives from major supercharger manufacturers, research institutes and universities at home and abroad participated in the forum. Shandong Hei Supercharger Co., Ltd. participated in the 2016 Internal combustion engine supercharger industry Development Forum seminar hosted by Professor Ma Chaochen, Department of Thermal Energy and Power Engineering, Beijing Institute of Technology. Liu Jianhua, vice president of the College of Machinery and Vehicles, delivered a speech, Ms. Wu Meiying of the Science and Technology Work Department of the China Machinery Industry Federation read out the list of the Technical Committee of the Engineering research center of the Internal combustion engine supercharging technology of the machinery ind
