Abstract
Systems and methods for detecting cavitation in a reciprocating positive displacement pump. Fluid pressure proximate the pump's suction manifold is compared to a predetermined pressure that would be conducive to cavitation. If the detected pressure approximates the predetermined pressure, the presence of cavitation is confirmed via correlation of increased vibration.
Claims15
A system for detecting cavitation within a positive displacement pump, the system comprising:
- a pressure sensor to detect fluid pressure at a location within the pump;
- an accelerometer to detect vibration in the pump;
- and
- a processor operably associated with the pressure sensor and accelerometer to:
- compare detected fluid pressure with a predetermined pressure to determine when detected fluid pressure approximates the predetermined pressure;
- and
- correlate detected fluid pressure with vibration when said detected fluid pressure approximates predetermined pressure to confirm the presence of cavitation.
