WHAT IS CLAIMED IS:

1. An active accumulator system, comprising:

a flow line coupled to a pump, wherein a fluid flows through the flow line to the pump; an accumulator coupled to the flow line;

a transducer coupled to the pump, wherein the transducer detects a parameter of the pump at an inlet of the pump; and

a controller coupled to the transducer and the accumulator, wherein the controller receives the parameter, and wherein the controller regulates air flow to the accumulator to adjust the accumulator to an optimal charge pressure based at least in part on the parameter.

2. The active accumulator system of claim 1 , wherein the parameter is indicative of a suction header pressure of the fluid.

3. The active accumulator system of claim 1, wherein the controller adjusts the accumulator to an optimal volume.

4. The active accumulator system of claim 1, further comprising:

a cavitation detector coupled to the pump, wherein the cavitation detector monitors a cavitation condition of the pump.

5. The active accumulator system of claim 4, wherein the cavitation detector monitors volumetric flowrates into and out of the pump.

6. The active accumulator system of claim 4, wherein the cavitation detector is coupled to the controller, and wherein the cavitation detector provides a feedback signal to the controller.

7. The active accumulator system of claim 4, wherein the controller receives the cavitation condition, and wherein the controller regulates air flow to the accumulator based on the cavitation condition.

8. The active accumulator system of claim 1 , wherein the transducer is a pressure transducer.

9. The active accumulator system of claim 1, further comprising:

an air source coupled to the accumulator; and

a regulator coupled to the air source, wherein the regulator at least one of allows air flow to the accumulator and restricts air flow to the accumulator.

10. The active accumulator system of claim 9, wherein the accumulator comprises the regulator.

1 1. A method, comprising the steps of:

detecting a parameter at a pump via a transducer coupled to the pump, wherein a fluid flows through a flow line to the pump;

comparing the parameter to a threshold parameter via a controller, wherein the controller is communicatively coupled to an accumulator; and

adjusting the accumulator to at least one of an optimal charge pressure and an optimal volume based on the comparison, wherein the accumulator is coupled to the flow line.

12. The method of claim 1 1 , wherein the parameter is a suction header fluid pressure of the fluid.

13. The method of claim 1 1, wherein the at least one of the charge pressure and the volume of the accumulator is adjusted to a minimum suction header pressure of the pump.

14. The method of claim 1 1 , wherein the threshold parameter is a volumetric flow rate indicative of a cavitation condition of the pump.

15. The method of claim 1 1 , wherein the adjusting the at least one of the charge pressure and the volume of the accumulator comprises at least one of adding gas to the accumulator and withdrawing gas from the accumulator.

16. The method of claim 15, wherein the at least one of adding gas to the accumulator and withdrawing gas from the accumulator is performed automatically by a regulator.

17. A non-transitory storage computer readable medium storing one or more instructions that when executed by the processor, cause the processor to:

detect a parameter at a pump via a transducer coupled to the pump, wherein a fluid flows through a flow line to the pump;

compare the parameter to a threshold parameter via a controller, wherein the controller is communicatively coupled to an accumulator; and

adjust at least one of a charge pressure and a volume of the accumulator based on the comparison, wherein the accumulator is coupled to the flow line.

18. The non-transitory storage computer readable medium of claim 17, wherein the parameter is a suction header fluid pressure.

19. The non-transitory storage computer readable medium of claim 17, wherein the one or more instructions, that when executed by the processor, further cause the processor to at least one of add gas to the accumulator or withdraw gas from the accumulator to adjust the accumulator to an optimal charge pressure.

20. The non-transitory storage computer readable medium of claim 17, wherein the one or more instructions, that when executed by the processor, further cause the processor to detect a cavitation condition and send a signal to the accumulator in response to detecting the cavitation condition.
