Suction manifold mounting for a fluid end for a high-pressure pump
View Patent ↗A suction manifold mounting for a fluid end of a high pressure pump having a frame assembly. The fluid end has a body forging with a detachable suction manifold plate. The plate is pivotally attached at opposed ends to a pair of swivel arms through a cooperating pair of yoke limbs. The swivel arms are rigidly affixed to the frame member. When attachment bolts are removed from the manifold plate, the plate may pivot from a first closed position wherein the mounting holes in the plate are aligned with mounting holes in the forging to a second open position.
1. A suction manifold for the fluid end of a high pressure pump comprising an elongated cylindrical tubular section, a manifold mounting plate attached to the cylindrical tubular section, and a pair of yoke links extending from opposed ends of the mounting plate, each yoke link comprises a first end having fastener holes and a second end provided with spaced apart legs, each leg having opposing aligned pivot pin apertures for rotably supporting the suction manifold.
2. A method of servicing a high pressure pump that includes a frame, a power end, a fluid end having a suction manifold including a manifold mounting plate removably secured to the fluid end by a plurality of bolts, and a plurality of suction intake valves located in the fluid end comprising:
removing the bolts that secure the manifold mounting plate to the fluid end;
rotatable supporting the manifold on a pair of support arms directly connected to the frame and mounting plate;
rotating the suction manifold about a fixed axis away from the fluid end thereby exposing the suction intake valves; and
servicing the suction intake valves.
3. A high pressure pump comprising:
a frame;
a power end mounted on the frame;
a fluid end mounted on the frame and connected to the power end;
a detachable suction manifold plate mounted to the fluid end;
a pair of swivel arms mounted on the frame at one end and having holes at a second end;
a pair of yoke links mounted on the suction manifold plate and having holes therein; and
a pair of pivot bolts extending through the holes in the second end of the swivel arms and the holes in the yoke links whereby the suction manifold plate is pivotably mounted on the frame so that it can be pivoted away from the fluid end.
4. A high pressure pump according to claim 3 wherein the inner diameter of the holes in the swivel arm and yoke links are substantially the same as the outer diameter of the pivot bolts so that the suction manifold plate rotates about a fixed axis.
5. A high pressure pump comprising:
a frame;
a power end mounted on the frame;
a fluid end mounted on the frame and connected to the power end;
a detachable suction manifold plate mounted to the fluid end;
said plate pivotably attached at opposed ends to a pair of opposed swivel arms through a cooperating pair of yoke links, said swivel arms attached to said frame; and
each said yoke link comprises a first end having fastener holes and a second end provided with spaced apart legs each having opposing aligned pivot pin apertures.
6. A high pressure pump as claimed in claim 5 wherein each swivel arm comprises an arcurate plate portion.
7. A high pressure pump as claimed in claim 5 wherein a top portion of the swivel arms includes a pivot aperture and a threaded bolt having opposed heads, the spaced apart legs of the yoke link mounted between one of the opposed heads and the swivel arm.
