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 (47)

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 85 to 95 degrees in relation to a gear teeth spread on the circumference of the rotating gear, and

a greater than half smooth gear circumference;

a motor shaft with a first key-way;

said rotating gear is pressed onto said motor shaft;

said rotating gear is further comprised with a second key-way that mechanically engages said first key-way of the 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 of said gear teeth engage said mangle rack teeth receptacles when said rotating gear is not engaging one of said transition pockets; and

a fluid end connected to said pumping house 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 mangle 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, and a planetary gear motor.

3. The reciprocating pump of claim 1 , wherein each said gear tooth further comprise;

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

4. The reciprocating pump of claim 1 , wherein

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

5. The reciprocating pump of claim 4 , wherein said connector further comprises a single plunger or multiple plungers.

6. The reciprocating pump of claim 5 , wherein when said rotating gear drives the mangle rack, said mangle rack moves the connector to create suction on a back movement and discharge on a forward movement.

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

8. 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 85 to 95 degrees in relation to a gear teeth spread on the circumference of the rotating gear, and a greater than half smooth gear circumference;

a motor shaft with a first key-way;

said rotating gear is pressed onto said motor shaft;

said rotating gear is further comprised with a second key-way that mechanically engages said first key-way of the 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

said activation causes said rotating gear to rotate and engage the gear teeth with said mangle rack teeth receptacles, moving said mangle rack and said attached connector in a reciprocating pumping motion;

wherein

multiple gear teeth of said 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 housing 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 mangle rack teeth receptacles.

9. The reciprocating pump of claim 8 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, and a planetary gear motor.

10. The method of claim 8 , wherein said each gear tooth further comprise;

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

11. The method of claim 8 , wherein said mangle rack is driven by said rotating gear attached to said motor shaft when said rotating gear is rotated and said gear teeth engage said mangle rack teeth receptacles, moving said mangle rack in a linear motion.

12. The method of claim 11 , wherein said connector further comprises a single plunger or multiple plungers.

13. The method of claim 12 , wherein when said rotating gear drives the mangle rack, said mangle rack moves the connector to create suction on a back movement and discharge on a forward movement.

14. The method of claim 8 , wherein said mangle rack drives multiple connectors.
