Abstract
A fluid end assembly comprising a fluid end housing with multiple discharge manifold ports which provide a fluid end assembly that overcomes problems associated with prior art single port discharge manifold designs that result in non-symmetrical flow of discharged fluids through the fluid end discharge valves, resulting in premature failure of said valves. The multiple port discharge manifolds overcome problems associated with non-symmetrical flow of discharged fluids through a fluid end discharge valve, thereby improving valve life and performance.
Claims18
A positive displacement pump fluid end, comprising:
- a plurality of fluid chambers, each individual fluid chamber in said plurality of fluid chambers further comprising:
- a discharge fluid chamber;
- a plunger bore;
- a discharge valve seat;
- a discharge valve;
- first and second discharge manifold ports on opposite sides of said each respective individual fluid chamber;
- and
- first and second discharge manifolds in fluid communication with said first and second individual discharge manifold ports, respectively, to receive fluid discharged therefrom;
- wherein:
- fluid is discharged through each respective discharge valve and seat by the forward stroke of a plunger in each respective plunger bore, and the flow of said discharged fluid is diverted around each respective discharge valve in a balanced flow pattern above said respective discharge valve to exit said fluid end through said respective first and second discharge manifold ports.
A positive displacement pump fluid end, comprising:
- a plurality of fluid chambers, each individual fluid chamber in said plurality of fluid chambers further comprising:
- a discharge fluid chamber;
- a plunger bore;
- a discharge valve seat;
- a discharge valve;
- a suction fluid chamber;
- first and second discharge manifold ports on opposite sides of said each respective individual fluid chamber;
- and
- first and second discharge manifolds in fluid communication with said first and second individual discharge manifold ports, respectively, to receive fluid discharged therefrom;
- wherein:
- the centerline of each of said respective discharge fluid chambers is offset from the corresponding centerline of each of said respective suction fluid chambers;
- and
- wherein:
- fluid is discharged through each respective discharge valve and seat by the forward stroke of a plunger in each respective plunger bore, and the flow of said discharged fluid is diverted around each respective discharge valve in a balanced flow pattern above each said respective discharge valve to exit said fluid end through said respective first and second discharge manifold ports.
