with the unit allowed the auger to spin at a minimum of 5
about 10 Hz.
In other words, the customer was running the equipment as
itself based on inefficient motor usage.
Proposed solution:
WSC was able to determine that the customers target auger
rate was between 1 and 4 rpm. The most practical way to
achieve the target was to change the drive and idle gearing
We replaced the drive sprocket with a smaller sprocket.
We replaced the idle sprocket with a larger sprocket.
Result:
The customer now has an operating range of 0 to 4.75rpm.
Benefits:
The motor operates inside of its intended speed range.
The VFD operates closer to its intendended speed range.
The customer has better adjustability inside of his intended
production range.
Benefits:
The motor operates inside of its intended speed range.
The VFD operates inside of its intended speed range.
The customer has better adjustibility inside of his intended
production range.
Before: auger turns too fast; speed range is not optimized for the customer.
|
During: Determine what sprockets are needed to hit the customers production range. re-design gear enclosure, generate a cad model.
|
After: We have hit the customers required production range of 1 to 4.75 RPM.
