Development of bushings and bearings for use in hot brine pumps

PDF Version Also Available for Download.

Description

The exploitation of geothermal resources often requires that naturally heated subterranean brines be pumped to the surface from depths of up to 6000 feet underground while minimizing heat losses and maintaining sufficient fluid pressure to prevent boiling. To accomplish this requires the use of downhole brine pumps capable of months of uninterrupted operation. Significant problems have occurred with pump lineshaft bearings in the geothermal wells. The objective of this research program was to determine the nature of the problems associated with commonly reported premature failures of downhole lineshaft pump bearings. Using the information gathered, a series of bearing endurance tests ... continued below

Description

The exploitation of geothermal resources often requires that naturally heated subterranean brines be pumped to the surface from depths of up to 6000 feet underground while minimizing heat losses and maintaining sufficient fluid pressure to prevent boiling. To accomplish this requires the use of downhole brine pumps capable of months of uninterrupted operation. Significant problems have occurred with pump lineshaft bearings in the geothermal wells. The objective of this research program was to determine the nature of the problems associated with commonly reported premature failures of downhole lineshaft pump bearings. Using the information gathered, a series of bearing endurance tests was performed on a variety of candidate bearing materials. These tests were accomplished using test rigs specially developed to simulate actual geothermal field conditions and to isolate specific bearing wear problems.
