Abstract

A reciprocating pump system for replacing a removable packing bore, the system includes a fluid end and a pump drive end. The fluid end includes a fluid inlet, a fluid outlet, a working barrel, a reciprocating member disposed in the working barrel, and the removable packing bore disposed within the working barrel. The pump drive end includes a gearbox integrally connected to a crankshaft, a crosshead, a transverse member configured to oscillate the reciprocating member of the fluid end in transverse motion. The removable packing bore and the transverse member are each configured to be connected to a packing bore connector.

Claims (14)

1. A method for replacing a packing bore, the method comprising:

attaching a packing bore connector to a packing bore disposed in a working barrel in a fluid end of a pump;

attaching the packing bore connector to a transverse member of a drive end of the pump;

wherein the packing bore connector is attached to the packing bore and the transverse member by physically accessing, through a space, a spacer section of the pump between the fluid end and the drive end of the pump without detaching the fluid end from the drive end;

rotating a crankshaft in the pump drive end to move the transverse member and the attached packing bore; and

removing the packing bore from the fluid end.

2. The method of claim 1 , further comprising, prior to attaching the packing bore connector to the packing bore, disconnecting the transverse member of the pump drive end from a reciprocating member of the pump fluid end.

3. The method of claim 1 , further comprising disposing a new packing bore in the working barrel.

4. The method of claim 3 , wherein disposing the new packing bore in the working barrel comprises:

disconnecting the packing bore from the packing bore connector;

connecting the new packing bore to the packing bore connector; and

rotating the crankshaft to insert the new packing bore into the working barrel.

5. The method of claim 1 , further comprising using a handle that is connected to the crankshaft to manually control strokes in the crankshaft to move the transverse member.

6. The method of claim 1 , further comprising controlling a gearbox connected to the crankshaft to control a speed and power of the transverse member.
