This paper discusses the design of a high pressure reinjection centrifugal compressor. This compressor was tested in the manufacturer’s shop under full load to simulate the field operating conditions in terms of inlet/discharge ...

This paper will describe the 570-K high performance industrial gas turbine and provide technical rationale for the design approach and performance limits. Construction details are discussed, including assembly of major ...

This paper presents the development and analysis of new critical speed criteria. The critical speed has been defined as the resonant speed of the rotor bearing system at which large response amplitudes can occur. However, ...

Couplings are one of the critical elements in a turbomachinery system. Malfunctions and failures results in significant outage time that, in most cases, is very costly to the user. This paper will deal with the application ...

The paper presents a review of electronic governors as developed and used by industry. The current interest in the conservation of energy has led many users of prime mover equipment to develop better control technology for ...

Self-acting fluid film bearings are the predominant choice for bearings used to position the rotors of high power turbomachinery. The present paper outlines the reasons for their selection, discusses the basic phenomenon ...

This paper covers turbomachinery repair techniques that have evolved from experiences in a large gasoline refinery. Engineering design problems and upgrading of all types of compressors, drivers, and accessories are ...

The similarity of failures of impellers in centrifugal compressors soon after initial startup and failures of impellers in other compressors after about seven years of successful operation and the test programs to define ...

For years, labyrinth shaft-end seals have been used for centrifugal compressors handling air and nonhazardous gases, and for low suction pressure compressors in hydrocarbon service. To prevent gas leakage from the hydrocarbon ...

Annular clearance spaces, such as impeller wearing rings, inter0stage bushes and balance drums in centrifugal pumps, or the fluid-filled clearance around the armature of the submerged motor, at a first glance present the ...
