Abstract
An auto cleaning system for cleaning a drilling fluid in a drilling operation includes a first line, a second line, an auto clean pump operatively connected to the first line and the second line, and an electromagnetic device around at least a portion of the first line, wherein the electromagnetic device is energized when the drilling fluid is passing through the first line. The auto clean pump is configured to receive the drilling fluid from the first line or the second line and remove metal particles from the drilling fluid. The system also includes a controller configured to determine a pressure difference in a line, at least partially open a valve to divert drilling fluid intake from one line the other, and close the first entrance valve to stop the drilling fluid from entering the first line.
