Abstract
A new pump design is described. The pump features a casing with a continuous enclosure extending from a power end of the casing to a fluid end of the casing for housing the reciprocating assembly of the pump, which includes a crankshaft, a plurality of control rods coupled to the crankshaft, and a plurality of crossheads coupled to the control rods. A detachable lid is attached to the casing at the power end and the fluid end of the casing, and encloses the reciprocating assembly. An alignment plate oriented substantially parallel to a stroke axis of the pump maintains alignment of the crossheads.
Claims20
A pump, comprising:
- a reciprocating assembly comprising a crankshaft, a plurality of control rods coupled to the crankshaft, and a plurality of crossheads coupled to the control rods, wherein the stroke of the crossheads define an axis of the pump, and the crankshaft is disposed transverse to the axis of the pump;
- a casing with a continuous enclosure extending from a power end of the casing to a fluid end of the casing for housing the reciprocating assembly;
- a detachable lid that fastens to the casing at the power end and at the fluid end;
- and
- a removable alignment feature aligned with the axis of the pump.
A pump, comprising:
- a reciprocating assembly comprising a crankshaft, a plurality of control rods coupled to the crankshaft, and a plurality of crossheads coupled to the control rods, wherein the stroke of the crossheads define an axis of the pump, and the crankshaft is disposed substantially perpendicular to the axis of the pump;
- a casing with a continuous enclosure extending from a power end of the casing to a fluid end of the casing for housing the reciprocating assembly;
- a detachable lid that fastens to the casing at the power end and at the fluid end;
- and
- a removable alignment feature oriented substantially parallel to the axis of the pump, wherein the alignment feature has a curved alignment surface for each crosshead.
