Monitoring Repairs To Your Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Many centrifugal pumps are doomed to premature failure because the total pump installation was not evaluated or the repair activity coordinated to correct the basic cause of the initial failure. Pump users have a great ...
Justifying The Reinstallation And Upgrading Of Problem ANSI Pumps At An Operating Chemical Plant
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Many facilities do not obtain the expected life out of ANSI and other centrifugal pumps, seals, and bearings that need to be obtained to be competitive in today’s market place. The analysis of this situation leads to two ...
Modern Manufacturing Of Advanced Impeller And Diffuser Vane Profiles
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Both fluid dynamics and manufacturing technology have seen rapid progress over the last few years. Vane profiles need no longer be developed in cavitation demonstration experiments, but can be optimized by computerized ...
Effect Of Mechanical Unbalance On Vibrations, Forces And Reliability Of A Single-Stage Centrifugal Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
The effect of rotor mechanical unbalance on pump vibrations was tested for a typical ANSI pump. It was found that significant damping of vibrations occurs at actual (wet) operations as compared to dry run. Rotor forces and ...
Experimental Evaluation Of High Energy Pump Improvements Including Effects Of Upstream Piping
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
The suction-impeller (single-suction) of a 33,500hp, four-stage barrel pump used in boiler feed service at a fossil fuel steam plant experienced operating life ranging from 6.0 to 19 months. Cavitation erosion on the suction ...
Magnetic Bearings As An Impeller Force Measurement Technique
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
The technique of measuring steady loads on centrifugal pump impellers via magnetic bearings is demonstrated and shown to be reliable way of clarifying loads, which have been traditionally difficult to determine both ...
Judge The Pump Hydraulic Design Through Numbers Before You Buy
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
A few well established hydraulic design parameters define the internal quality of an impeller design. Becoming familiar with those parameters and understanding their limits will enable pump buyers to make better pump buying ...
A Name Well Chosen
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Centrifugal Pump Application - Key Hydraulic And Performance Criteria
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
The essential elements to be reviewed when considering a centrifugal pump application are highlighted. The purpose is to ensure the procurement and/or application of a centrifugal pump which optimizes reliability, energy ...
Design And Implementation Of A Mechanical Seal Improvement Program At An Oil Refinery
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
A mechanical seal improvement program was initiated at a major oil refinery. The program was intended to improve seal reliability, reduce emissions, improve safety, and reduce costs. A partnership agreement was reached ...
