摘要： A method for maintaining a downhole pump impeller of a geothermal downhole pump includes locating a line shaft to a selected depth, monitoring the depth of a lowermost distal end of the line shaft using a monitor positioned at a lowermost distal end of the line shaft, determining that the depth of the lowermost distal end of the line shaft has significantly changed, and taking a corrective action to return the depth of the lowermost distal end of the line shaft to the selected depth. The depth of the lowermost distal end is monitored by directing a beam of light emitted from a housing mounted on a outer portion of the downhole pump onto a plurality of reflective elements located on the line shaft distal end, and determining whether a receiver mounted in the outer portion receives light reflected from one of the plurality of reflective elements.
