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 ...
A Fundamental Understanding Of Rotordynamics From A Light Rub (Bounce).
(Texas A&M University. Turbomachinery Laboratories, 1992)
Machinery users, designers, and analysts are both alarmed and fascinated by the occasional occurrences of contact between a rotating shaft and a stationary part. "Rubs," a common description for such contact, are typically ...
Do It Right The First Time - A Review Of An Ethylene Plant Turbomachinery Commissioning Test.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Every user would like to check the mechanical integrity of rotating equipment in the field before startup. In the case of large compressor trains with steam turbine drives, running a mechanical string test with associated ...
Reliability Criteria For Turbine Shaft Based On Coupling Type - Geared To Have Flexibility.
(Texas A&M University. Turbomachinery Laboratories, 1990)
A turbine shaft end at the coupling is exposed not only to constant torque load but to various variable loads as well. These externally imposed variable loads come from sources like compressor surge, misalignment between ...
Shaft Riding Brushes To Control Electric Stray Currents.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Electric discharge causing bearing and seal damage may occur in any nonelectric machine as a result of static electricity, accidental electromagnetic self excitation of casings, rotors, piping, foundations, galvanic effects, ...
Rotordynamic Aspects Of A New Hermetically Sealed Pipeline Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Mopico is an oilfree motor pipeline compressor of fully integrated design with no sealing requirements against atmospheric pressure and supported on magnetic bearings. The application of magnetic bearings for this machine ...
Turbomachinery Balancing Considerations.
(Texas A&M University. Turbomachinery Laboratories, 1991)
The mechanics of balancing, including details concerning tolerances and specifications, tooling, balancing machines, and procedures have been presented many times in the past. However, very little information has been ...
Recent Case Histories With Coupling Enclosures.
(Texas A&M University. Turbomachinery Laboratories, 1990)
Coupling enclosures are oil-tight guards which serve the double purpose of protecting people from the rotating coupling and returning oil that escapes past the seals back to the oil reservoir. Enclosures were, and still ...
Recent Experience With Large Liquid Injected Rotary Screw Process Gas Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Advances in manufacturing techniques and design enhancements for such components as shaft seals have made it possible for liquid flooded rotary screw compressors to achieve availability, reliability, and overall performance ...
Adaptation Of A Propylene Refrigeration Compressor With Dry Gas Seals.
(Texas A&M University. Turbomachinery Laboratories, 1991)
The retrofit of a 35000 hp, two-case centrifugal, propylene refrigeration compressor with tandem dry gas seals in DuPont's ethylene plant at Orange, Texas, is described. The installation of these dry gas seals is one of ...
