Study on vibration of reciprocating pump pipelines
Due to the periodic movement of the piston in the reciprocating pump, the fluid will cause 8 pressure pulsation, and the vibration of the pipeline will lead to instrument distortion, pipe failure 9 and equipment damage. Therefore, it is necessary to study the vibration phenomena of the 10 reciprocating pump pipeline based on the pressure pulsation theory. This paper starts from the 11 reciproca...
متن کاملThe diminishing role of biochemistry in subarachnoid haemorrhage diagnosis.
The incidence of subarachnoid haemorrhage (SAH) is 24.6 per 100,000 population 1 . Case fatalities are about 44% in Europe 2 . SAH is misdiagnosed in 12 â 50% of cases. Non-contrast CT scanning is positive in 98% of patients with SAH who present within 12 hours of the bleed. There is a rapid clearance of subarachnoid blood over time and after one week, the diagnostic sensitivity of CT scannin...
متن کاملSerum lactate as a prognostic factor in coronary artery bypass graft operation by on pump method
Background: Lactic acidosis in cardiac surgical patients is a manifestation of systemic inflammation and excess pro-inflammatory cytokine production. This investigation was designed to integrate basic concepts about lactate acidosis with a clinically used of serum lactate in patients under coronary artery bypass surgery (CABG) by on pump method. Methods: From August to September 2012, 15 patie...
متن کاملDevelopment of Linguistic Rules Diagnosis of Failure in Centrifugal Pump for Use in Expert System
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...
