DETECTION, CAUSES AND WAYS OF PREVENTION OF CAVITATION IN PUMPS

Abstract

- Pumps and turbines are an integral part of the hydro machine family and play a vital role in many large industries. These machines are required to operate efficiently for the maximum output, and thus they must be free from any damages or problems. Cavitation is a phenomenon occurring in hydro machines (more specifically, pumps and turbines) which is related to the change and fluctuation in the pressure of fluids, the same phenomenon further leads to cavitation erosion. It turns out to be disadvantageous for the machines and deteriorates their performance and efficiency. This paper consists of a detailed study about the phenomenon, including how can we detect the damage and root of the problem. Further, their causes are discussed with the ways of prevention. This will help in taking necessary measures from the beginning so that the problems with the machines can be avoided.
