Nantong Po Ju 190 Turbocharger Turbocharger SJ150

Nantong Po Ju 190 Turbocharger SJ150 turbocharger turbocharger ① maintaining normal operating temperature. When the supercharger working, turbine shell normal temperature is about 400 ℃, the temperature of the compressor housing not hot as appropriate, in use, if the diesel oil is too large, oil too late, prolonged overload or regular H-throttle, the exhaust gas temperature will be too high and because the turbocharger overheating, increased wear. If the turbine end seal failure, the oil within the turbocharger turbine housing fleeing, with the high temperature exhaust gas discharged together with the cylinder, resulting in excessive oil consumption, exhaust pipe smoke there. If the compressor end seal failure, the oil within the turbocharger compressor housing will fleeing, with intake air is sucked into the cylinder combustion, also cause excessive oil consumption, exhaust smoke, soot also resulted in an increase in the cylinder. . (Booster Zhang: 15165664175 ② maintain normal diesel engine oil pressure lubrication system in operation, when the oil lubrication system pressure is lower than 015MPa, should stop and check, in case of poor lubrication and ablation turbocharger rotor shaft and bearing. . Oil pressure is not too high, so as not to oil fleeing into the turbine room or compressor room. Engine low idle time not too long, to prevent low oil pressure leaving turbocharger poor lubrication. ③ enhance air filter maintenance work. To injected into the cylinder diesel combustion, need a lot of clean air supply diesel engine turbocharger installation, the fuel injection pump adjusted accordingly large amount of oil, if the air filter clogging and into the gas shortage, diesel power will It will be significantly reduced. Therefore, to strengthen the maintenance of the air filter to ensure its normal operating condition. In addition, if the filter element is damaged or sealing gasket aging failure, the turbocharger due to gray sand intrusion speed instability, increased noise and lead bearings, seals and air seal assembly increased wear. It should be noted that the maintenance of the air filter, do not let hard objects falling into the intake manifold, so as not to inhale the turbocharger crushed or broken impeller rotor shaft, and may trigger pull Cylinder accident. 5, proper maintenance supercharger in use, should always check and tighten bolts between turbocharger three housing, eliminating oil spills, leakage phenomenon. diesel per work 500 ~ 1000h, should be removed turbocharger, check whether the rotor rotating flexible, turbocharger inlet and return port with or without carbon deposition, and carefully cleaned to ensure uninterrupted oil. scrape microscopic dust deposited on the throat of the compressor, clean water intermediate shell sandwich The scale, gas and oil chamber closed to traffic, removing the turbine, and the turbine nozzle ring shell coke, cleaning each gas seals and seal parts, and check damage and replace if necessary. When Working turbocharger Since the turbine housing and compressor housing are thin-walled castings, beating avoid collision, if necessary, use a wooden hammer tapping, do not use iron to prevent break must sign the original position of the rotor shaft assembly assembly, so as not to affect the movement balance when the assembly should be kept clean, can not let debris fall into the housing cavity or conduit. oil into the intermediate housing on the oil port should be mounted vertically, from the turbocharger outlet pipe connected to the crankshaft should be gradually curved received box to middle of any "dead corner", to prevent the oil back to the oil does not flow to the turbine room or leaving the compressor room leak (turbocharger Zhang: 15165664175
