Assessing Rotor Stability Using Practical Test Procedures.
(Texas A&M University. Turbomachinery Laboratories, 1992)
Perturbation testing of an industrial centrifugal compressor in an at-speed balancing chamber is discussed in PERTURBATION TESTING FOR ASSESSING ROTOR STABILITY. The instrumentation and data acquisition techniques are ...
The Use Of Honeycomb Seals In Stabilizing Two Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1993)
The stabilizing effects achieved by replacing labyrinth seals with honeycomb seals are described. Although honeycomb seals have been used for some time in high pressure compressors and other turbomachinery applications, ...
Hydraulically Rerating Centrifugal Pumps To Improve Reliability
(Texas A&M University. Turbomachinery Laboratories, 1998)
The authors present two case studies where improperly applied hydraulics resulted in poor mechanical reliability, due to chronic flow instability problems. A successful hydraulic rerate of these pumps, which required minimal ...
Using Fiber-Optic Pressure Sensors To Detect Cavitation And Flow Instabilities In Centrifugal Pumps
(Texas A&M University. Turbomachinery Laboratories, 1998)
This paper introduces the benefits of applying the fiber-optic Fabry-Perot interferometer (ffpi) pressure sensor as a means of detecting cavitation and flow instabilities in centrifugal pumps. The need for monitoring dynamic ...
Using Fault Trees To Determine The Root Cause Of Rotating Equipment Failures
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
The great value of using multidisciplinary task groups to conduct root cause failure analyses (RCFA) on pump and rotating equipment failures is discussed. The RCFA method offers its users a structured means of achieving ...
