A low flow coefficient unshrouded centrifugal compressor would give up clearance in relation to the span of the blades, because centrifugal compressors produce a sufficiently large pressure rise.

Regardless of the type of failure in many cases catastrophic failure can be avoided by applying the following guidelines Looseness due to excessive clearances in the bear- ing or bearing support is also seen at two time's running speed, except the axial probe does not show any excursions. Volume pockets are most easily added to the head-end of the compressor cylinder. A custom engineered replacement cylinder was determined to be the preferred solution, but lead time was also prohibitively long. As the crosshead moves back and forth within the guide the piston rod exerts a vertical motion on it. The unusually large outer head requires a large number of bolts that must be removed for routine service of the piston, wear band and compression rings.
