Pump System
A pump system that has a power end and a fluid end assembly. The fluid end assembly includes a plunger configured to translate within a plunger bore. The fluid end further includes a suction valve assembly and a discharge valve assembly. The power end is configured to use a pony rod to induce movement of the plunger within the fluid end assembly to generate a pressure differential. The suction valve assembly and the discharge assembly operate in response to the pressure differential to move the fluid. A straight valve seal is located within the suction valve assembly and/or the discharge valve assembly to distribute forces incurred by movement of valves within the fluid end assembly.
1 . A pump system, comprising:
a power end assembly having a pony rod;
a fluid end assembly having a plunger for generating an alternating pressure differential in the fluid system, the power end being configured to induce translation of the plunger within the plunger chamber to pressurize a charge fluid;
a suction valve assembly and a discharge valve assembly configured to selectively operate in response to the pressure differential; and
a straight valve seal configured to seal the suction valve assembly and discharge valve assembly in a straight bore within the fluid end assembly.
2 . The pump system of claim 1 , wherein the power end includes a multi-piece connecting rod configured to use a plurality of threaded fasteners to couple individual portions together to reduce wear of the connecting rod.
3 . The pump system claim 1 , wherein power end includes a connecting rod bearing housing in communication with a connecting rod, the bearing housing including a channel and associated bevel area for the distribution of lubrication.
4 . The pump system claim 1 , wherein the plunger and the pony rod are coupled together via a pony rod adapter.
5 . The pump system claim 1 , wherein the pony rod adapter is a dove-tail clamp.
6 . The pump system claim 5 , wherein the pony rod adapter uses a non-threaded relationship to couple the pony rod and the plunger together.
7 . The pump system claim 1 , wherein the suction valve and the discharge valve are intersect a centerline of the fluid end at an obtuse angle, the centerline being coaxial with an axis of the plunger.
8 . The pump system claim 1 , wherein the suction valve defines a first centerline and the discharge valve defines a second centerline, the first centerline and the second centerline being parallel with each other and perpendicular to a third centerline defined by the plunger.
9 . The pump system of claim 1 , wherein the suction valve assembly includes a seat portion and a guide portion configured to properly align the valve.
10 . The pump system of claim 1 , wherein at least one of the suction valve assembly and the discharge valve assembly includes a valve insert to seal a valve opening.
11 . The pump system of claim 1 , further comprising:
a recirculating manifold having a reducer configured to optimize the distribution of charge fluid through a feeder, the feeder coupled to a suction valve assembly.
12 . The pump system claim 1 , further comprising:
a rock screen insert configured to filter out particulates from the charge fluid;
the rock screen insert being located within the suction valve assembly.
13 . The pump system of claim 12 , wherein the rock screen insert maintains a front valve guide to improve performance of the suction valve assembly.
14 . The pump system of claim 1 , wherein the fluid end assembly includes a packing nut configured to seal around the plunger, the packing nut configured to receive automated adjustment during operation of the pump system.
15 . The pump system of claim 1 , wherein the packing nut includes a monitor to provide an operator operational feedback concerning the condition of the packing nut during operation of the pump system.
16 . The pump system of claim 14 , wherein the packing nut includes a bellows forming an annular volume for reception of a working fluid configured to regulate the pressure on the packing nut.
17 . The pump system of claim 14 , wherein the packing nut includes an annular volume between a piston and a body for reception of a working fluid configured to regulate the pressure on the packing nut.
18 . The pump system of claim 1 , wherein the suction valve assembly and the discharge valve assembly are configured to accept a dual guided valve.
19 . The pump system of claim 1 , wherein the suction valve assembly includes a locking mechanism configured to permit removal of a suction valve with a single hand.
20 . The pump system of claim 1 , wherein the fluid end assembly is configured to receive bores and cutouts configured to reduce stress concentrations within a fluid end.
