Investigation into Hydraulic Gear Pump Efficiencies during the First Few Hours of the Pumps' Lives and a Comparative Study of Accelerated Life Test Methods on Hydraulic Fluid Power Gear Pumps. Parts 1 and 2.

Abstract

This interim report summarizes the results obtained in evaluating the changes in overall efficiency of 18 hydraulic gear pumps during the first few hours of the pumps' lives, that is, during the break-in period. A literature search and a mail survey of industry was conducted in order to devise a break-in procedure. Measurement procedures were developed to provide traceability, calibration and verification of the working instruments. Originator-supplied keywords include: Hydraulic fluid power gear pumps, Contamination, Roll-off cleanliness, Traceability, Instrumenation calibration, Measurement accuracy, Pressure calibration, Flow calibration, Torque and load cell, and Temperature calibration.
