Design flaws cause catastrophic failure in a geothermal power station hotwell in New Zealand.
Cavitation
The positive displacement technology handles backpressure fluctuations, cavitation and air entrainment.
These pumps prevent equipment from corroding, provide lower costs and increase efficiency.
Because cavitation is unavoidable in pump operations, understanding how to reduce it using NPSH calculations is necessary to maintain pump functionality and health.
Lev Nelik answers a reader's question on thermodynamic sub-processes that are highly time dependent
This material stands up to pump upsets such as cavitation and dry running.
Higher temperatures reduce water’s lubricating effect and stress seal faces.
Drops in pressure and shifting flow rates were significant hurdles of a $403 million water project.
The solution to pump impellers suffering from cavitation is finding a material that can withstand high pressure levels, endure harsh environments and be machinable.
