Operating Experience With Improved Steam Turbine Packing Rings.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The losses in turbine performance due to excessive leakages in the labyrinth seals can result in significant heat rate degradation to the turbine cycle. The modified packing arrangement described helps eliminate the rubs ...
Large Motor Specification and Selection
(Texas A&M University. Turbomachinery Laboratories, 1988)
The induction motor has been the work horse of industry for many years. It has achieved this position by virtue of its ruggedness, and relative low cost. Induction motors include the popular squirrel cage and the versatile ...
Improving Plant Economy Through Retrofit And Maintenance Of Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1988)
Retrofits on compressors can become attractive if the operating requirements of a plant change. Often, compressor modifications are imposed by process changes due to market demands or new process technologies. Sometimes, ...
Turbine-Generator Life Assessment/Extension.
(Texas A&M University. Turbomachinery Laboratories, 1988)
The approach and methodology to life assessment/extension are described. Items considered are nondestructive testing, material testing, flaw sizing, stress analysis, fracture mechanics analysis and cumulative damage analysis. ...
Turbomachinery Health Measurement Application And Misapplication
(Texas A&M University. Turbomachinery Laboratories, 1988)
All machinery vibrates, has heat generated internally, and begins to wear as soon as it is put into service. The monitoring process must be customized for each class of equipment. If possible, each machine should be evaluated ...
Emergency Turbine Repair Procedures
(Texas A&M University. Turbomachinery Laboratories, 1988)
Emergency repairs of a cracked steam turbine disc can be accomplished effectively by using sound basic engineering principles. One such method used to expedite a repair is reported.
Dry Gas Compressor Seals
(Texas A&M University. Turbomachinery Laboratories, 1988)
Dry gas seals can eliminate some of the conventional problems associated with seal oil systems. Increased safety, lowered maintenance and improved reliability are key considerations for retrofitting with gas seals. ...
Full Fluid Film Face Seals
(Texas A&M University. Turbomachinery Laboratories, 1988)
The basic types of seal face lubrication are described and the basic design concepts and deflection analysis are discussed. Present field installations are presented, along with operating conditions and common problems ...
