Abstract
Systems and methods to enhance the flow of fracturing fluid into a wellhead during a high and the second plungers may pump a second fracturing fluid different from the first fracturing fluid.
Claims20
A pump, comprising:
- a pump frame at least partially defining a shaft aperture;
- a crankshaft extending through the shaft aperture;
- a plurality of first plungers connected to the crankshaft and configured to reciprocate relative to the crankshaft as the crankshaft rotates, each of the plurality of first plungers configured to reciprocate in a first plane;
- a plurality of second plungers connected to the crankshaft and configured to reciprocate relative to the crankshaft as the crankshaft rotates, each of the plurality of second plungers configured to reciprocate in a second plane so as to define a non-zero offset angle between the first plane and the second plane;
- a plurality of crankpins connected to the crankshaft and each being connected to one of the plurality of first plungers and one of the plurality of second plungers;
- and
- a plurality of first connector rods each having a plunger end connected to one of the plurality of first plungers, and a crank end connected to a corresponding crankpin of the plurality of crankpins, and each crank end of the plurality of first connector rods comprising a pair of crank end connectors;
- and
- a plurality of second connector rods each having a plunger end connected to one of the plurality of second plungers, and a crank end connected to a corresponding crankpin of the plurality of crankpins, and each crank end of the plurality of second connector rods comprising a crank end connector disposed between the pair of crank end connectors of a corresponding one of the plurality of first connector rods,
- wherein a first pair of plungers includes a first one of the plurality of first plungers and a first one of the plurality of second plungers,
- wherein a second pair of plungers includes a second one of the plurality of first plungers and a second one of the plurality of second plungers, and
- wherein the first pair of plungers is offset from the second pair of plungers such that the first pair of plungers and the second pair of plungers are engaged in a non-consecutive firing sequence.
