The trend toward higher speed, higher power density liquid turbomachinery has inevitably increased the potential for fluid/structure interaction problems, and the severity of those problems. Fluid structure interaction phenomena can lead to increased wear and to structure failure. There are many factors affecting hydraulic and dynamic performance of pumping plants. These factors contribute to d...
PURPOSE Failure mode and effects analysis (FMEA) was used to evaluate a smart i.v. pump as it was implemented into a redesigned medication-use process. SUMMARY A multidisciplinary team conducted a FMEA to guide the implementation of a smart i.v. pump that was designed to prevent pump programming errors. The smart i.v. pump was equipped with a dose-error reduction system that included a pre-de...
The number of off-pump coronary artery surgery procedures in high-risk patients such as renal failure, hepatic failure and in anticoagulant drug using patients is increasing. The associated co morbidity and repeated use of electrocautery in postoperative bleeding, caused a susceptibility of patients to pressure or electrocautery ulcers. During a period of three years, 1400 off-pump coronary art...
water is the most essential component for sustaining lives of humans and other living creatures. supplying potable water with adequate residual pressure is a fundamental responsibility of city administration, which they do during normal conditions. but sometimes, abnormal conditions are formed resulting pressure deficient conditions during the daily operations of water distribution networks. th...
Operational failures in centrifuge pumps could be hydraulic or mechanical. However, most of these mechanical and hydraulic failures are connected cause of their operational nature and finding the right cause is due to considering numerous mechanical and hydraulic signs and parameters in pumps. On the other hand, due to non-linear and fluctuant behavior of pumps in the matter of time and not pre...

The shaft bearing is the key component of water pump and its fatigue failure results in abnormal operation system. However, mechanisms are still unclear. In this paper, analysis on engine was carried out by using measurement material composition properties, observation macro micro morphologies, theoretical failure. wear behavior were clarified, prevention measures further proposed. reflected fr...
