Case Study 3 – Booster Fan

Case Study 3 – Booster Fan

Problem:

The company’s booster fan carries a high volume of abrasive particulate in the gas stream. Because this is a large, single width, single inlet fan, the velocity of the particulate erodes the casing cut-off point and its surrounding scroll area.

Solution:

Robinson designed, manufactured and installed a new pie-shaped cut-off area that can be easily changed out with a spare. This cut-off is a small area in the scroll that is separate from the removable pie that enables the rotor to be removed.

Result:

Due to this extra removable part in the housing, the customer now can change this piece in a one-day planned outage. The worn part can therefore be repaired at a reasonable price to become his spare.
