Abstract
A light-weight reciprocating element is disclosed. The reciprocating element may include a body defining a cavity, the body having a closed distal end and an open proximal end opposite the closed distal end, wherein the body is configured to apply a pressure to a working fluid. The cavity extends from the open proximal end towards the closed distal end. The reciprocating element may include an insert disposed in the cavity, the insert is configured to prevent debris from accumulating within the cavity.
Claims17
A lightweight reciprocating plunger for a high pressure pump comprising:
- a plunger body defining a cavity, the plunger body having a closed distal end and an open proximal end opposite the closed distal end, wherein the plunger body is configured to reciprocate within and with respect to one or more packing seals to apply a pressure to a working fluid in a fluid end of the high pressure pump, wherein the cavity extends from the open proximal end towards the closed distal end;
- and
- an insert disposed in the cavity, wherein the insert comprises an agitator configured to move freely within the cavity to prevent debris from accumulating within the cavity.
A reciprocating pump, comprising:
- a power end configured to generate pumping power;
- a fluid end coupled to the power end, the fluid end configured to deliver a fluid from an inlet bore, through a chamber, and to an outlet bore as the power end generates the pumping power;
- a lightweight reciprocating plunger configured to drive the fluid through the fluid end, the lightweight reciprocating plunger having an open proximal end and a closed distal end, the distal end coupled to the power end and the proximal end received in the fluid end, the lightweight reciprocating plunger defining a cavity extending from the proximal end to the distal end;
- and
- an insert disposed in the cavity, wherein the insert comprises an agitator configured to move freely within the cavity to prevent debris from accumulating within the cavity.
A method comprising:
- drawing, via a lightweight reciprocating plunger, a fluid from an inlet bore to a pumping chamber;
- guiding a portion of the fluid from the pumping chamber into a cavity of the lightweight reciprocating plunger;
- preventing debris from the portion of the fluid disposed in the cavity from accumulating within the cavity via an insert by agitating the fluid disposed in the cavity via the insert to mix the debris with the fluid, wherein the insert comprises an agitator configured to move freely within the cavity;
- and
- driving, via the lightweight reciprocating plunger, the fluid to an outlet bore.
