Maintenance & Reliability
Reliable machines require competent maintenance skills
A proactive approach will provide significant returns through better utilization of existing staff
Retrofitting multijack tensioners on a combustion gas turbine generator
Consider this technology for difficult bolting applications
Fieldbus improves control and asset management
Substantial benefits are realized from increased diagnostics and process data
HP Reliability: Consider overspeed protection retrofits
The overwhelming majority of small turbine overspeed trip devices are mechanical; they incorporate a spring-activated trip bolt that moves out and contacts a trip lever whenever a pres..
Case history 6: Keep those bolts tight
It’s important to keep operating loads less than the bolt preload
HP Reliability: Consider disc pumps where impeller pumps fail
Until recently, finding a suitable pump was difficult for plants pumping viscous fluids or fluids that undergo viscosity change. Here, using conventional centrifugal pumps may lead to poor performance..
HP Reliability: Strategic mechanical seal partnerships
Not all mechanical seal supplier agreements benefit both parties equally. We have recently seen some rather one-sided ones. At a recent users conference, the suggestion that the "partner" should discl..
