Abstract

A reciprocating injection pump with a reciprocating block driven by a rotating gear, the gear having a substantially circular shape with gear teeth formed on the rotating gear the rotating gear is attached to a rotating motor.

Claims (50)

1. A reciprocating pump comprising:

a pumping house assembly housing;

a rotating gear;

a reciprocating block which is a mangle rack with two opposite ends comprising two transition pockets that cup said rotating gear and mangle rack teeth receptacles on said mangle rack;

said rotating gear further comprising; gear teeth covering an angle from 65 to 125 degrees in relation to the gear teeth spread on the circumference of the rotating gear, and a greater than half smooth gear circumference;

a motor shaft;

said rotating gear is mechanically connected to said motor shaft;

a connector for moving fluid attached to at least one of said mangle rack opposite ends;

said connector comprising a second shaft attached to the outer surface of said reciprocating block; and

a motor attached to said motor shaft; wherein

multiple gear teeth engage said mangle teeth receptacles when said rotating gear is not engaging said transition pocket; and

a fluid end connected to said pumping assembly; wherein

said transition pockets that cup said rotating gear are designed in a semicircle to mechanically engage with said greater than_half smooth gear circumference to allow for said rotating gear to momentarily disengage said rack teeth receptacles.

2. The reciprocating pump of claim 1 further comprising:

said motor may be selected from the group of motors consisting of parallel shaft motor, dual shaft motor, stepper motor, right angle motor, fractional or whole horsepower AC or DC motor, brushed or brushless motor, explosion proof motors, or planetary gear motor.

3. The reciprocating pump assembly of claim 1 wherein,

an activation of said motor results in the rotation of said motor shaft, resulting in the rotation of said rotating gear which interacts mechanically with said mangle rack teeth, resulting in the axial or reciprocating motion of said mangle rack and the attached connector, which pumps fluid out of the reciprocating pump assembly.

4. The reciprocating pump assembly of claim 1 further comprising a coupling between a pump head and a yoke, providing a quick disconnect between the pump head and the yoke, wherein the yoke is attached to the pump housing assembly.

5. The reciprocating pump of claim 1 , wherein said gear teeth further comprise:

a pressure angle to allow from no pressure to 7,000 PSI pressures in operation.

6. The reciprocating pump of claim 1 , wherein

said mangle rack is driven by said gear attached to said motor shaft when said gear is rotated and said gear teeth engage said mangle rack teeth, moving said mangle rack in a linear motion.

7. The reciprocating pump of claim 6 , wherein said connector further comprises a single plunger, or multiple plungers.

8. The reciprocating pump of claim 7 , wherein when said gear drives the mangle rack, said mangle rack moves the connector to create suction on a back movement and discharge on a forward movement.

9. The reciprocating pump of claim 1 , wherein said mangle rack drives multiple connectors.

10. A method for pumping a fluid using a reciprocating pump comprising the steps of:

activating a reciprocating pump comprising;

a pumping house assembly housing;

a rotating gear;

a reciprocating block which is a mangle rack with two opposite ends comprising two transition pockets that cup said rotating gear and mangle rack teeth receptacles on said mangle rack;

said rotating gear further comprising; gear teeth covering_an angle from 65 to 125 degrees in relation to the gear teeth spread on the circumference of the rotating gear and a smooth gear circumference covering a complimentary angle between 235 to 295 degrees opposite and in relation to the gear teeth spread on the circumference of the rotating gear;

a motor shaft;

said rotating gear is mechanically connected to said motor shaft;

a connector for moving fluid attached to at least one of said mangle rack opposite ends;

said connector comprising a second shaft attached to the outer surface of said reciprocating block; and

a motor attached to said motor shaft; wherein

activation of the motor causes the motor shaft to rotate, causing said gear to rotate and engage the gear teeth with said mangle rack teeth, moving said mangle and said attached connectors in a reciprocating pumping motion; wherein,

multiple gear teeth engage said mangle teeth receptacles when said rotating gear is not engaging said transition pocket; and

a fluid end connected to said pumping assembly; wherein

said transition pockets that cup said rotating gear are designed in a semicircle to mechanically engage with said half smooth gear circumference to allow for said rotating gear to momentarily disengage said rack teeth receptacles.

11. The method of claim 10 further comprising:

said motor may be selected from the group of motors consisting of parallel shaft motor, dual shaft motor, stepper motor, right angle motor, fractional or whole horsepower AC or DC motor, brushed or brushless motor, explosion proof motors, or planetary gear motor.

12. The reciprocating pump assembly of claim 10 further comprising a coupling between a pump head and a yoke, providing a quick disconnect between pump head and the yoke, wherein the yoke is attached to the pump housing assembly.

13. The method of claim 10 , wherein said gear teeth further comprise:

a pressure angle to allow from no pressure to 7,000 PSI low to high pressures in operation.

14. The method of claim 10 , wherein

said mangle rack is driven by said gear attached to said motor shaft when said gear is rotated and said gear teeth engage said mangle rack teeth, moving said mangle rack in a linear motion.

15. The method of claim 14 , wherein said connector further comprises a single plunger, or multiple plungers.

16. The method of claim 15 , wherein when said gear drives the mangle rack, said mangle rack moves the connector to create suction on a back movement and discharge on a forward movement.

17. The method of claim 10 , wherein said mangle rack drives multiple connectors.
