Cavitation & NPSH are widely talked about terms associated with centrifugal pumps Cavitation & NPSH these two terms are closely interrelated. NPSH is the cause & Cavitation is the effect. NPSH NPSH stands for Net Positive Suction Head. To put it simply – it is the resultant pressure energy or head available at the pump’s …
Water carry-over is the most significant factor for cylinder liner wear & cold corrosion Combustion air (Scavenge air,Charge air) drawn in from the surrounding by the Turbocharger passes through the Air Cooler for cooling down.This cooling down increases density as well as mass of the air supplied to the engine cylinders and ensures that there …
