In a periodic test of a baghouse dust collection system, the PD compressor’s belts were found almost worn out, though still running doggedly. The PD compressor supplies compressed air of about 8 psi to the low-pressure, high-volume pulse cleaning system of the baghouse. The belts had to be replaced. Per the model number on the old ones, the customer bought a pair of new ones, NAPA A38. Belt replacement for this PD compressor The alignment of the sheaves was checked first; it was good. The sheaves and their inner faces were cleaned up and inspected; they were fine. The motor base has a jacking bolt, so it is easy to adjust the position of the motor. The new belts were rotated by hand for a couple of rounds to make sure they sat in the groove properly. We then measured the span-length of the belt and the sheave diameter, read the motor RPM, and took the V-belt tension table by Browning as a reference to decide the deflection force of the belt as 6 pounds. After the new belts ...
