A complex mechanism is called a turbocharger, which is used in engine design to improve performance and power. The turbine is under heavy stress, because of what this part is capable of failure, despite high reliability and long working life.
The turbocharger is repairable, therefore, not all faults require a complete replacement of the unit. In many cases repair of turbines Kharkiv Dergachi turns out to be cheaper, than replacement.
How is turbocharger repair carried out??
Turbine repair requires the appropriate qualifications and knowledge of the technological nuances of the process. Turbocharged compressor machining is a delicate process, where every millimeter plays a role. For this reason, repair work is carried out on the basis of specialized service stations..
Sequence of repair work
Restoration and repair of turbocharged compressors is carried out according to the following algorithm:
- Repair work begins with a visual inspection to determine visible defects and damage.
- The second step is to carry out dismantling work - the turbocharger is disassembled into individual components, to install, which components are worn out and need to be replaced.
- Compressor components are thoroughly cleaned, remove greasy stains and wash. Further valves, the body and external elements are machined. In most cases, sandblasting is used for cleaning..
- Change bearings if necessary, shafts, wheels and other parts, based on the device of a specific turbine model.
- To tune the compressor, be sure to balance the shaft. First they do it disassembled, and then - in the assembled. After balancing, the turbocharger core is assembled.
- The assembled compressor is tested under heavy loads on special equipment.
Upon completion of the repair, a conclusion is drawn up on the turbocharged compressor and a guarantee is provided. The exact order of repair work and their number is determined based on the type of breakdown, as well as turbine models. If buying a new part is cheaper, than a major overhaul, then they refuse to repair work. The exceptions are cases, when buying a new compressor is not possible due to the lack of a corresponding model on the market.
