The severe vibration of a screw compressor outlet piping system caused the fatigue failure of some thermowells and the unscheduled shut down of the system. The main reasons of the abnormal vibration in the outlet piping system were investigated by developing an acoustic model to simulate the gas pulsation and establishing two finite element models to conduct the mechanical vibration analyses. T...
In this paper, the transient refrigerant gas flow in a two-cylinder rolling piston type rotary compressor is simulated using STAR-CD, a general computational fluid dynamics (CFD) software. Three models with different suction piping systems are calculated respectively, one is two suction pipes were connected from accumulator to each cylinder separately (separate suction piping system), the other...
Description: Practical, easy–to–follow advice that saves lives Based on the author's thirty years of hands–on experience working in the field of industrial fuel systems and combustion equipment safety, this book integrates safety codes with practical, tested, and proven guidance that makes it viable to specify, operate, and maintain industrial fuel and combustion systems as safely as possible. ...
9 http://ammtiac.alionscience.com http://wstiac.alionscience.com BACKGROUND Modern US Navy ships use considerable quantities of piping to carry fresh water, ballast water, chilled water, wastewater and fuels throughout the ship. Traditionally, copper-nickel (90Cu-10Ni) alloy pipes have been used, but they are heavy, subject to both corrosion and moderate bio-fouling, and are expensive to procur...
The cost of damage to the non-structural systems in critical facilities like nuclear power plants and hospitals can exceed 80% of the total cost of damage during an earthquake. The failure of nonstructural components, especially, piping systems led to leakage of water and subsequent shut-down of hospitals immediately after the event. Consequently, the evaluation of performance of these types of...
For polishing the ultra-thin TMT M3MP, a polishing support system with 18 hydraulic supports (HS) is introduced. This work focuses on the designing and testing of these HSs. Firstly the design concept of HS system is discussed; then mechanical implementation of the HS structure is carried out, with special consideration of fluid cycling, work pressurization and the weight component. Afterward t...
