Abstract
A fluid handling protection system configured to prevent cavitation in a first pump can include a first pump, a first pump fluid inlet line, a first pump fluid outlet line, a first pump drive unit, wherein the first pump drive unit is operatively coupled to the first pump, a first pressure sensor, and a control unit, wherein the control unit is operatively coupled to the first sensor and the first pump drive unit.
Claims20
A system comprising:
- a first pump;
- a first pump fluid inlet line;
- a first pump fluid outlet line;
- a first pump drive unit, wherein the first pump drive unit is operatively coupled to the first pump;
- a first pressure sensor;
- a control unit, wherein the control unit is operatively coupled to the first sensor and the first pump drive unit;
- wherein the control unit, in operation, continuously receives, in real time, a first pressure signal from the first pressure sensor;
- wherein the control unit is configured to compare the first pressure signal with a first pressure threshold;
- wherein the first pressure threshold represents a minimum inlet pressure;
- wherein the first pressure threshold is based on a real time first pump speed;
- and
- wherein the first pressure threshold comprises a lower first pressure setpoint and a higher first pressure setpoint, wherein the first pressure threshold is dynamic and has a first direct relationship between 0% first pump speed as a maximum at the lower first pressure setpoint and 100% pump speed as a maximum at the higher first pressure setpoint.
