Cleaning and drying of injection tubes

Injection tube washer

A parts washer for cleaning and drying gasoline injection tubes was required in three different references:

  • Ø21.5 mm, length 243 mm, thickness 2.5 mm.
  • Ø23 mm, length 335 mm, thickness 3 mm.
  • Ø28 mm, length 342 mm, thickness 4 mm.

The treatment cycle had to last a maximum of 16 seconds (1 tube every 16 seconds = 225 tubes/hour).

The contaminants to be removed were coolant and chips from cutting operations, and the tube surface had to be completely degreased for subsequent welding thereof.
