HP Reliability: Consider toroidal chamber rotary compressors
In 1970, the first of five toroidal chamber rotary compressors entered service in nuclear test loops. Each of these machines was used to circulate 2,240 scfm of CO2 at 660°F; the s..
Benchmarking: a reliability driver
Approaches range from purely quantitative to highly qualitative
HP Reliability: Machine scanning is coming of age
For quite some time, our columns and bound texts have explained that forward-looking companies are no longer expecting experienced vibration analysts and technical personnel to look for..
HP Reliability: Cost-effective sheave maintenance
Good sheave alignment will increase efficiency by reducing premature wear or failure of belts, pulleys and bearings. This can be accomplished by several different alignment methods, suc..
HP Reliability: Consider floating piston compressors
Process plants have for decades applied nonlubricated reciprocating compressors. Early designs used carbon piston rings and rider bands; these were soon followed by Teflon, filled Teflo..
HP Reliability: Consider machine condition inspection systems
Your plant is probably depending on a dedicated group of reliability professionals to first collect and then analyze machinery vibration and other equipment condition data. You undoubte..
