Detecting Cavitation in Centrifugal Pumps
ently Nevada Corporation is continually investigating methods to help our customers protect and manage all their machinery. This includes integrated solutions to address machines of all sizes, speeds, and criticality. Within two of the largest markets that we serve, Hydrocarbon Processing and Power Generation, the most common machine type is the process pump. The vast majority of these pumps ar...
متن کاملPrevention of tissue damage by water jet during cavitation
Cavitation bubbles accompany explosive vaporization of water following pulsed energy deposition in liquid media. Bubbles collapsing at the tip of a surgical endoprobe produce a powerful and damaging water jet propagating forward in the axial direction of the probe. We studied interaction of such jet with tissue using fast flash photography and modeled the flow dynamics using a two-dimensional R...
متن کاملDetection of Cavitation in Centrifugal Pumps
Pumps are designed and manufactured to operate well away from the cavitation condition and thus the factors affecting the onset of cavitation are important. A specially designed test rig was and constructed so that the onset of cavitation could be studied visually while obtaining actual NPSH data. The magnitude of the NPSH level at 3% drop in total discharge head of a pump was determined at dif...
متن کاملCavitation in Reciprocating Positive Displacement Pumps
Owing to their impressive properties reciprocating positive displacement pumps are used in many applications. Pumping fluids at high delivery pressures and metering are the areas of frequent use. The design of reciprocating pumps requires an exact knowledge of the appearing phenomena such as unacceptable pipeline pulsation and harmful cavitation. But cavitation in reciprocating positive displac...
متن کاملCavitation in Turbo Pumps - Part 1
Associate Profe ssor of M echanical Engineering, California Institute of Technology, Pasad e na , Calif. Assoc. Mem. ASME A free-streamline flow through a cascade of semi-infinite flat plates is taken as a simplified model of the cavitation process in a helical inducer pump. The length and thickness of the resulting cavity is determined as a f unction of blade geometry and cavitation parameter....
