TPL?三、涡轮机端水洗三、涡轮机端水洗1.Adjust the engine load until the scavenge air pressure is in the range of pscav=0.3 0.6 bar pscav=0.3 0.6 bar(overpressure).The temperature before turbocharger has to be below 430C and the auxiliary blower should be in operation.2.Open the drain cock A of the gas outlet casing and check whether exhaust gas emerges3.Open valve B slowly until the pressure gauge C(water pressure pwater)indicates:p pwaterwater=1.0 bar=1.0 bar4.Inject water for 5 minutes while keeping the engine load constant5.Close valve B6.Close the drain cock A of the gas outlet casing清洗程序：ABB TPL?三、涡轮机端水洗三、涡轮机端水洗 The engine should be run at least for further 10 minutes to prevent corrosion of the internal casing surfaces.Depending on the load only little or no water flows out the drain hole A.Water drain is not relevant for the cleaning effect.Water injection can be confirmed with reduced T/C speed during cleaning and lower gas temperature after turbochareger.If more than one turbocharger is mounted it is recommend to clean one after the other.注意事项：ABB TPL?三、涡轮机端水洗三、涡轮机端水洗ABB BBC三、涡轮机端水洗三、涡轮机端水洗1.Reduce the rpm to 50%load.2.Open the drain cock(A)(Pos.1-3).3.Close the drain cock(B).4.Open valve(C).5.Open the valve(D)slowly!until the pressure gauge shows 2.5 bar.6.When the water from the drain pipe 3 appears clean,the cleaning is completed(after about 10 minutes).7.Close the valve(D).8.Close the valve(C).9.Open the drain cock(B).10.Close the drain cock(A)(Pos.2-1).11.After completing the cleaning,operate at the same load for 5 minutes.12.Listen to the turbocharger,to make sure that it runs smoothly(without vibrations)when increasing the rpm.If not,repeat the cleaning.ABB
