Turbomachinery Problems - Lube And Seal System Revisited
(Texas A&M University. Gas Turbine Laboratories, 1978)
Even an apparently well-designed lube and seal system can and will cause turbomachinery problems to occur if all operating parameters are not considered in the design of the lube and seal system. Lube and seal system design, ...
Table of Contents for the Proceedings of the 7th Turbomachinery Symposium
(Texas A&M University. Gas Turbine Laboratories, 1978)
Improving Cooling Tower Fan System Efficiencies
(Texas A&M University. Gas Turbine Laboratories, 1978)
After a look at the problem for air cooled heat exchangers and cooling towers using axial fans, ways to improve system efficiencies in three areas are discussed: before the fin system design is finalized, improvements in ...
Planning Turbomachinery Overhauls And Documenting The Results
(Texas A&M University. Gas Turbine Laboratories, 1978)
The paper covers the subject of overhauling turbomachines with particular emphasis on practical field procedures and proven concepts. It does not dwell on one type of machine, but multi-stage centrifugal compressors and ...
Plant Lubrication
(Texas A&M University. Gas Turbine Laboratories, 1978)
The correct lubrication of plant equipment is an important factor in sustaining production with reduced equipment outage and lower maintenance costs. A well planned and coordinated lubrication program is a necessary ...
The Role Of Hydraulic Balance In Mechanical Pump Seals
(Texas A&M University. Gas Turbine Laboratories, 1978)
The mechanical seal is the least reliable component in centrifugal pumps. Most seals fail prematurely, i.e., before the seal face wears out. One cause of premature failure is face instability when the seal geometric balance ...
Transient Analyses Of Synchronous Motor Trains
(Texas A&M University. Gas Turbine Laboratories, 1978)
This paper discusses the philosophy of optimum location of torsional critical speeds which will be excited by the transient startup, as well as methods of adjusting the resonant frequencies. Pulsating torque, average torque, ...
Using Modified Acoustic Emission Techniques For Machinery Condition Surveillance
(Texas A&M University. Gas Turbine Laboratories, 1978)
Acoustic emission is the release of high frequency sound energy in a material under strain. It is the result of microscopic changes in material structure and is associated with deformation and defect growth. Until about ...
High Speed And Large Capacity Compressor-Driving Turbines For Chemical Plants
(Texas A&M University. Gas Turbine Laboratories, 1978)
This paper gives a brief description of compressor-driving steam turbines for use in chemical plants. Turbines used for ethylene plants, ammonia plants and LNG plants, in particular, are large-capacity, high-speed ...
Design Automation Of Centrifugal Compressors
(Texas A&M University. Gas Turbine Laboratories, 1978)
Centrifugal compressors used in various plants come in diverse specifications with regard to capacity, pressure and gas handled. In designing such compressors, important considerations are to shorten design time and save ...
