Abstract: An intermittent flushing plunger packing assembly is described herein. The packing assembly includes a plurality of annular seals disposed about the plunger configured to reciprocate along a linear axis within the fluid bore of the pump, and an annular packing nut disposed circumferentially about the plunger and configured to retain the plurality of annular seals and adjust a combined height of the plurality of annular seals. A selected one of the plurality of annular seals proximate to the fluid cylinder of the pump has a flushing fluid chamber in fluid communication with a flushing fluid port coupled to a first one-way check valve allowing a pressurized flushing fluid to be introduced and retained within the flushing fluid chamber and creating a fluid barrier to prevent frac fluid in the fluid cylinder from bypassing the annular seals.

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.

Abstract: An electrically-actuated linear pump includes a linear actuator housing coupled to a screw housing. A rod is configured to linearly translate within screw housing and the linear actuator housing, the rod includes a threaded portion disposed axially between a first plunger portion and a second plunger portion. A linear actuator is disposed within the linear actuator housing and includes a drive mechanism in meshed engagement with the threaded portion of the rod, the meshed engagement operable to linearly translate the rod, the linear actuator being electrically-actuated. The pump includes a first fluid end and a second fluid end disposed opposite the first fluid end, each fluid end configured to receive and discharge a fluid. Translation of the rod toward the first fluid end discharges the fluid from the first fluid end and simultaneously draws the fluid into the second fluid end.

Abstract: A cable-tie carrier is disclosed herein that includes a chip holder with a recess cavity for holding an electronic chip and a cable that is removably attached to the chip holder. The electronic chip stores identification information or testing data that may be used to identify and track the part. External computing devices (e.g., smart phone, tablet, scanner) may access the stored identification information or testing data for a user. The electronic chip is fastened, magnetically attached, or stuck with adhesive to the chip holder to position a transmitter (or antenna) to face out of the recess cavity.

Abstract: The oil quality in an oil reservoir of a pump is monitored using the disclosed oil-monitoring sensor. The oil-monitoring sensor includes a first capacitive portion for measuring oil level and a second capacitive portion for measuring dielectric constant of the oil. Changes in dielectric constant of the oil are indicative of degradation of the quality of the oil (e.g., due to contaminants, oxidation, etc.) So oil-monitoring sensor is used to indicate various parameters about the oil quality to an operator. Using the disclosed sensors, the quality of the lubricant and/or cooling oil used by the pump may be monitored without needing to be present at the pump, or without needing to access the interior of the pump (or oil reservoir).

Abstract: A valve assembly for a hydraulic frac pump includes a valve body having a spherical sealing surface, a valve seat having a circular concave sealing surface that receives and accommodates the spherical sealing surface of the valve body. The valve seat forms a fluid passageway, where the fluid passageway is completely closed when the valve body is received and accommodated in the valve seat in a closed position. The valve assembly further includes a stopper disposed above the valve body to restrict movement of the valve body when it is lifted off of the valve seat in an open position.
