Increased Lift for Feather Valves by Elimination of Failures Caused by Impact
نویسنده
چکیده
The maximum lift that can be used in a feather valve for a particular application is limited by the valve failures that occur if the lift is too high. This limit ~as been increased by testing valves with a high lift and investigating the resulting failures. This has shown that the primary cause of failure is damage caused to the strip by impact of the strip on the guard. As a result of this work, several design modifications have been made to the feather valve and these allow reliable operation at considerably higher lifts than were previously practical. This will, of course, have a direct influence on compressor performance.

Elimination of Flow-induced Instability from Steam Turbine Control Valves
This paper describes two steam turbine governor valve failures in the same installation, the troubleshooting that determined the root cause, and the new valve designed to prevent similar failures. The original governor valve design had been used successfully for many years in large multistage, multivalve steam turbines, but apparently was not reliable at the high steam pressures employed today....
متن کاملA Computational Study on Avian Flapping Flight and the Influence of Feather Separation
Bird flight is an area of significant interest due to the utilization and control of unsteady aerodynamic effects via flapping. Although modern aerodynamics were originally inspired by bird flight, contemporary computational and experimental work associated with flapping flight focuses on insect flight. The purpose of the present paper is to improve the understanding of avian flight by investig...

Background; Feather waste is generated in large amounts as a by-product of commercial poultry processing. The main component of feather is keratin. The main purpose of this study was to identify Bacillus spp. (the keratinolytic bacteria) that are able to degrade the feather for producing keratin. Methods; Bacillus spp. Were isolated from the waste of poultries located in Miyaneh city. The bact...
متن کاملImpact of Energy Subsidies Elimination on Technology Gap Ratio in Cucumber Production
This paper presents an analysis of technical efficiency and technology gap ratio (TGR) in greenhouse cucumber in Fars Province, Iran. Cucumber production was chosen for this study for the reason that greenhouse productions in this provincemainly have focused on this product. The data used in this study was obtained from a random sample of 127 greenhouses in Fars Province for 2010 to 2011. Metaf...
