Abstract
A linear pump includes a centrally-disposed drive system and a plunger having a center portion coupled to the drive system, and first and second fluid ends disposed at the first and second ends of the plunger. The pump further includes first and second packing seals each being disposed about the plunger to isolate fluids within the respective first and second fluid ends. First and second adapters are disposed at an interface between the drive system and respective first and second fluid ends, each adapter incorporating an angled deflector configured to deflect and redirect high-pressure fluids escaping past the respective packing seal toward the drive system.
Claims20
A reciprocating pump comprising:
- a drive system having a first adapter coupled to a first end of the drive system and a second adapter coupled to a second end of the drive system;
- a plunger having a center portion coupled to the drive system, and the plunger further having first and second end portions;
- a first fluid end receiving the first end portion of the plunger, the first fluid end coupled to the first adapter;
- a second fluid end receiving the second end portion of the plunger, the second fluid end coupled to the second adapter;
- and
- first and second packing seals each being disposed about the plunger to isolate fluids within the respective first and second fluid ends;
- wherein the first adapter houses comprises an angled deflector formed from a portion of the first adapter, the angled deflector positioned within a void of the first adapter, the angled deflector positioned within the void nearer to the drive system than to the first fluid end, the angled deflector configured to sealingly engage a portion of the plunger and to deflect and redirect high-pressure fluids escaping past the first packing seal away from the drive system.
A linearly-actuated pump comprising:
- a plunger having a center portion and first and second end portions, the center portion being coupled to a drive system capable of effecting linear displacement of the plunger;
- a first adapter coupled to a first end of the drive system and housing a first portion of the plunger;
- a first fluid end receiving the first end portion of the plunger, the first fluid end coupled to the first adapter;
- a second adapter coupled to a second end of the drive system and housing a second portion of the plunger;
- a second fluid end receiving the second end portion of the plunger;
- and
- first and second packing seals each being disposed about the plunger to isolate fluids within the respective first and second fluid ends;
- wherein at least one of the first adapter and the second adapter comprises an angled deflector formed from a portion of the respective adapter, the angled deflector sealingly encircling the plunger, the angled deflector contacting the plunger and having a conical surface extending from an inner diameter of the angled deflector and tapering away from the respective first or second packing seal, the deflector configured to deflect and redirect high-pressure fluids escaping past the respective packing seal away from the drive system.
A pump comprising:
- a plunger coupled to a drive system at a first end portion of the plunger;
- a fluid end receiving a second end portion of the plunger;
- a packing seal disposed about the plunger to isolate fluids within the fluid end;
- an adapter disposed between the drive system and the fluid end and coupled to the drive system and to the fluid end;
- and
- an angled deflector formed from a portion of the adapter, the angled deflector having an inner diameter encircling at least a portion of the plunger and providing a seal against the plunger, the angled deflector configured to deflect and redirect high-pressure fluids escaping past the packing seal away from the drive system.
