Cleaning components mechanically

5.5

Introduction

Compressor wheels can be heavily contaminated by badly filtered intake

air, as can turbines by heavy fuel oil operation or coked oil. Such

contamination may possibly no longer be removed through cleaning

during operation and must be cleaned mechanically during the standard

service intervals (see chapter entitled Service work).

Professional overhauling of the components by an ABB Turbocharging

Service Station is required, preferably using the cleaning method

described in the following.

CAUTION

Choosing cleaning tools
Turbocharger components are sensitive to mechanical damage. The

use of needle guns or other impact tools, for example, damages the

components. Depending on the specification, nozzle rings have

protective coatings, which can also be damaged.



Only use soft tools such as scouring cloths, brushes or wire brushes.



In the event of heavy contamination, the cleaning methods described

in this chapter such as soaking can be repeated until a satisfactory

result has been achieved.

NOTICE

Disassembly and assembly
Disassembly and assembly of the parts is described in the chapter

entitled Fitting and dismantling.



Dispose of contaminated water and cleaning agents in an

environmentally compatible manner, professionally and in accordance

with valid local regulations.
