Car Turbocharger housing on transport and cleaning pallet

New at Piller: Cleaning machine for turbocharger housings

Clean Parts - compact machine - energy-saving operation

New cleaning machine developed to clean machined castings

Final cleaning of machined turbocharger housings
High cleaning quality and short cycle times in combination with low space and energy requirements, and this for the lowest possible investment. In cycle times under 60 seconds the system removes dirt and clamping chips from the workpieces in several zones and finally dries the parts. In the actual version, the system is specially adapted to the size of the parts and to the requirements of the turbochargers. Maximum 600 microns particle size after cleaning was the challenging quality specification.

Maximum processing time and machine flexibility

On a specially designed cleaning pallet, the turbochargers are very quickly fed through the machine via chain drive. In the individual process zones, the cleaning platforms are decoupled from the chain and are individually movable. This allows optimal alignment process to spraying technique. Thanks to the very quick part transport, the available processing time in each zone can be better exploited. This construction also allows flexibility for different type turbocharger, which can be cleaned in the washing machine. The spraying technique is divided into three areas. Two of them work with low pressure and a chamber is equipped with a high-pressure cleaning system. This one works with pressures below 200 bar and removes reliably all clamping chips from the workpieces.

Energy efficiency all around

Each process zone has been constructed so that the water quantity and the pressure level have been very reduced to the real requirements. Much attention was paid also to the entire air flow inside and outside the machine. ”We have realized an energetic high-class exhaust concept", tells Chief Technology Officer Thomas Piller about the overall design of the machine. With a reduced quantity of water, divided into two baths, you can expect manageable energy costs in daily operation. According to the customer's requirement, bag filters perform the filtration and the bath heating is electric. Of course we can basically also implement alternative concepts. In the drying zone, optimized air quantity exhaust technique and a vacuum chamber are used.

Future prospects

We are confident that this system meets exactly the demands imposed in the turbocharger Industry.

The new system combines cleaning quality, productivity, flexibility and energy efficiency in a brand new way and can be adapted to other parts.
