Abstract

A controller for a pump for pumping a drilling fluid from a storage unit to a downhole tool includes at least one actuation device coupled to a control console of the pump, and at least one connector coupled to the at least one actuation device and a pump control mechanism of the control console.

Claims

1. A controller for a pump, the pump adapted to pump a drilling fluid from a storage unit to a downhole tool, comprising:

at least one actuation device coupled to a control console of the pump; and

at least one connector coupled to the at least one actuation device and a pump control mechanism of the control console.

2. The controller of claim 1, wherein the pump control mechanism is a pump control knob.

3. The controller of claim 1, wherein the pump control mechanism is a pump control lever.

4. The controller of claim 1, wherein the at least one actuation device is magnetically coupled to die control console.

5. The controller of claim 1, wherein the at least one connector comprises a connecting rod.

6. The controller of claim 1, wherein the at least one connector comprises a belt.

7. The controller of claim 6, wherein the at least one pump control mechanism comprises a pump control knob having a stem and the belt is operatively coupled to the stem.

8. The controller of claim 1, wherein the at least one connector comprises a drive wheel.

9. The controller of claim 8, wherein the at least one actuator mechanism further comprises a tension arm.
