    摘要： A lubricating sealing system for a fluid end includes a fluid end, a sleeve, a plunger, and a lubrication system. The sleeve is coupled to an internal surface of the fluid end. The plunger reciprocates in a linear manner through the sleeve and into a pressure chamber of the fluid end. The lubrication system is in communication with the plunger and configured to provide lubricant through an interior of the plunger for routing to surfaces between the plunger and the sleeve. The lubricant is pressurized and moved via the reciprocating of the plunger and create a positive pressure on the lubricant over the pressures experienced in the pressure chamber of the fluid end. The positive pressure creates a barrier and pushes away contaminants from the plunger seals thereby avoiding wash out.

    摘要： A box lubricator that includes a pump with a piston housing and piston. The piston housing extends from a first end to a second end, and includes a bore extending through the piston housing from the first end of the piston housing to the second end of the piston housing. The piston housing also includes a recess disposed at the second end of the piston housing, the recess being concentric with the bore and comprising a diameter larger than a diameter of the bore. The piston is disposed inside the bore of the piston housing. At least one elastomeric seal is disposed inside the recess of the piston housing and around the piston. In some embodiments, a ball and socket joint connects the piston to the rocker arm assembly. In some embodiments, a fluid passage and a check valve are disposed inside the piston.

    摘要： An apparatus according to which a power end of a reciprocating pump assembly includes a block having bores formed therethrough, and crossheads disposed in the bores and adapted to reciprocate therein. A lubrication pump is in fluid communication with the bores. The pump is operable to pump lubrication fluid into each of the bores so that the crossheads are lubricated as they reciprocate within their respective bores. In another aspect, a power end includes a crosshead block and a power frame connected thereto, the frame including rib plates and supporting the crosshead block. In yet another aspect, a method includes casting a crosshead block; fabricating rib plates; connecting the rib plates to form a frame; and connecting the cast crosshead block to the frame. In some embodiments, the power ends may be used in oilfield operations such as, for example, the cementing, acidizing, or fracturing of a subterranean wellbore.
