Waterhammer Caused by Intermittent Pump Failure in Pipe Systems Including Parallel Pump Groups
The use of pumps linked in parallel or series in large scale pipe systems is usually inevitable, to meet the required head and discharge. Transient flow occurs following a pump failure in a pump group as a result of variations in the flow rate. This research is an investigation about waterhammer caused by one or more pump-switch off in a pump group when they are connected in parallel. The opera...
متن کاملA precursor in waterhammer analysis – rediscovering
In 1883 Johannes von Kries published the theory of waterhammer in a study of blood flow in arteries. He derived the “Joukowsky formula” before Joukowsky (1898) and Frizell (1898) did. He considered skin friction in unsteady laminar flow and thus derived formulas for wave attenuation and line pack. The theory was confirmed by experimental results obtained in rubber hoses. In 1892 he published th...

Stress analysis of reciprocating pump pipeline system in oil station
The strong vibration of reciprocating pump in oil transportation station pipeline system will seriously affect the safe running of the equipment and pipeline. And the resonance between pipe and equipment will cause more severe damage. Therefore before the formal operation of station, not only static stress analysis, but also modal analysis and vibration analysis are necessary for the reciprocat...
