Abstract
A reciprocating injection pump is disclosed including but not limited to a reciprocating block driven by a rotating gear, the gear having a substantially circular shape with four gear teeth formed on the rotating gear along approximately one fourth of the substantially circular shape, the rotating gear is attached to a rotating motor, the rotating motor having a right-angle motor shaft.
Claims20
A reciprocating injection pump comprising:
- a reciprocating block driven by a rotating gear, the gear having a substantially circular shape with four gear teeth formed on the rotating gear along approximately one fourth of the substantially circular shape, the rotating gear is attached to a rotating motor, the rotating motor having a right-angle motor shaft.
A method comprising:
- rotating a gear in a reciprocating block driven by a rotating gear, the gear having a substantially circular shape with four gear teeth formed on the rotating gear along approximately one fourth of the substantially circular shape, the rotating gear is attached to a rotating motor, the rotating motor having a right-angle motor shaft, wherein the motor shaft is connected to the right-angle motor a minimal distance minimizing the length of the motor shaft to reduce torque losses associated with longer shaft lengths, wherein the rotating motor shaft is directly coupled to rotating gear so that gear teeth are rotated by the rotating motor shaft and during rotation, the rotating gear teeth alternately engage the upper gear teeth and lower gear teeth formed inside of the block, wherein the rotating gear causes the reciprocating block to linearly translate back and forth along a longitudinal axis of a plunger, wherein the rotating gear rotates clockwise causing rotating gear teeth to alternately engage upper block gear teeth and moves the reciprocating block to the right along the longitudinal axis plunger and wherein after the rotating gear teeth exit the upper gear teeth the rotating gear teeth alternately engage lower block gear teeth and moves the reciprocating block to the left along the longitudinal axis plunger and wherein the stepper motor steps to rotate the motor shaft clockwise a programmable number of degrees less that a 360 degrees and less that full rotation of the motor shaft to move the right end of the lock to the right, and the processor then reverses the direction of the stepper motor to rotate the motor shaft counter clock wise programmable number of degrees less than 360 degrees and less than full rotation of the motor shaft to move the left end of the lock to the left.
