Modernization of the diffuser
and guide vane units of a soda gas compressor,
Soda Plant, Sterlitamak, Russia
Scope of the work and basic technical data of the
units made by Turboservice was as follows:
- The technical documentation necessary for seven
types of stationary cast units of individual compressor
stages was prepared. The units incorporated internal
water cooling systems as part of their complex gas flow
path shape.
- Basic dimensions of the units
- outer diameter 1300 mm
- width 250 mm
- weight 1150 kgs
Geometry of the guide vanes and diffusers has
been adjusted to the existing body. Sealings of the gas
and water flow systems were improved by tight fittings of
the units into the compressor case.
- Due to an aggressive environment the units have
been made of an alloy cast iron that is resistant to
stress corrosion and erosion.
- Addition the technology of casting has ensured
very good surface quality, without need for additional
machining.
