(R) Aerospace - System Integration Factors That Affect Hydraulic Pump Life
|Publication Date:||1 February 2017|
This SAE Aerospace Information Report presents the following factors that affect hydraulic pump life and performance:
a. The need to supply hydraulic fluid at the correct pressure and quality to the pump inlet port
b. Considerations for the pump output
c. Factors to be considered for the pump case drain lines
d. The mounting of the hydraulic pump
e. Hydraulic fluid properties, including cleanliness
Field of Application
This document applies to pumps operating constantly or for long periods at quasi-constant speed such as engine driven pumps or within narrow speed ranges such as electric motor driven pumps.
Wide speed range and intermittent duty cycle pumps, such as those used in Electrohydrostatic Actuators, are not covered by this document.
