Power end of reciprocating pump with fastener assembly
A power end frame includes a plurality of rings cooperatively defining an interior of the power end frame configured to enclose a portion of a crankshaft of a power end of the reciprocating pump and a rod extending through each ring of the plurality of rings to couple each ring with an adjacent ring of the plurality of rings.
1 . A method of manufacture of a power end frame of a reciprocating pump, comprising:
aligning a plurality of rings with one another to define an interior of the power end frame configured to enclose a portion of a crankshaft of a power end of the reciprocating pump, wherein each ring, including a first ring and a second ring, of the plurality of rings comprises a flange, and aligning the plurality of rings with one another provides a space between the flange of the first ring of the plurality of rings and the flange of the second ring of the plurality of rings;
positioning a sleeve within the space between the flange of the first ring and the flange of the second ring;
inserting a rod through the plurality of rings; and
securing the plurality of rings together with the rod such that the sleeve abuts the flange of the first ring and the flange of the second ring.
2 . The method of claim 1 , wherein securing the plurality of rings comprises coupling a lock to an end of the rod, the end of the rod extending beyond a lateral boundary of the plurality of rings.
3 . The method of claim 1 , wherein aligning the plurality of rings with one another comprises aligning a respective hole formed through each ring of the plurality of rings with one another, and inserting the rod through the plurality of rings comprises inserting the rod through each respective hole formed through each ring of the plurality of rings.
4 . The method of claim 1 , comprising inserting the rod through the plurality of rings and the sleeve.
5 . The method of claim 1 , comprising positioning plates between adjacent rings of the plurality of rings.
6 . The method of claim 5 , wherein inserting the rod through the plurality of rings comprises inserting the rod across the plates.
7 . A reciprocating pump, comprising:
a fluid end configured to enclose a reciprocating element configured to receive and discharge fluid; and
a power end configured to enclose a portion of a crankshaft configured to operate the reciprocating element, wherein the power end comprises:
a plurality of rings, wherein each ring of the plurality of rings comprises a base, a flange extending from the base, a first surface configured to couple to the fluid end, a second surface opposite to and facing away from the first surface, and a third surface extending between the first surface and the second surface, and wherein the second surface and the third surface intersect to cooperatively define the flange; and
a rod extending through the flange of each ring of the plurality of rings.
8 . The reciprocating pump of claim 7 , wherein the flange extends away from the first surface.
9 . The reciprocating pump of claim 7 , comprising a sleeve positioned between and abutting the flange of a first ring of the plurality of rings and the flange of a second ring of the plurality of rings.
10 . The reciprocating pump of claim 7 , wherein each ring of the plurality of rings is positioned adjacent to one another along an axis, and the rod extends through the flange of each ring of the plurality of rings along the axis.
11 . The reciprocating pump of claim 7 , wherein each ring of the plurality of rings comprises an opening, the openings of the plurality of rings cooperatively define an interior of the power end, and the flange of each ring of the plurality of rings extends away from the interior of the power end.
