  • Patent number: 10662941
    Abstract: The present disclosure relates to a modular fluid pump system for configuring a fluid pump in a selected one of first and second configurations. The system may have a first pump casing with a first diameter, and a second pump casing with a second diameter smaller than the first diameter. A tubular frame may be included along with a first float having a first diameter positioned over the tubular frame for sliding longitudinal movement along the tubular frame. The first pump casing may be used to configure the fluid pump in the first configuration, to thus provide a first degree of clearance between the first float and an inner surface of the first pump casing, or alternatively the second pump casing may be used to configure the fluid pump in the second configuration, which provides a second degree of clearance between the first float and an inner of the second pump casing.

  • Patent number: 10655623
    Abstract: A plunger pump fluid end assembly design in which the suction valve and seat is aligned with the plunger and the fluid end housing is constructed with multiple modules. Modules are held in a rigid assembly by staybolts that connect to the power end of the plunger pump. Said staybolts pass though bores in the central fluid module and the suction seat module and bound by a conventional threaded nut. Packing box modules are bound to the central fluid module by bolts that also pass through separate bores in the same central module. A suction valve spring retainer/plunger spacer within the plunger bore of the assembly shields the intersection of the plunger bore and the discharge bore from destructive erosion damage.

  • Patent number: 10626858
    Abstract: A fluid machinery, a heat exchange equipment, and an operating method for the fluid machinery. The fluid machinery includes: an upper flange (50); a lower flange (60); a cylinder (20); a rotating shaft (10), the axis of the rotating shaft (10) being eccentric to the axis of the cylinder (20) and at a fixed eccentric distance; and a piston component (30), the piston component (30) being provided with a variable volume cavity (31). Because the eccentric distance between the rotating shaft (10) and the cylinder (20) is fixed, the rotating shaft (10) and the cylinder (20) rotate around the respective axes thereof during motion, and the position of the center of mass remains unchanged, so that the piston component is allowed to rotate stably and continuously when moving within the cylinder (20); and vibration of the fluid machinery is effectively mitigated.

  • Patent number: 10619462
    Abstract: A gas compressor system is provided to operate at a well site and to inject a compressible fluid into a wellbore in support of a gas-lift operation. Methods and systems are provided that allow for the automated individual control of discharge temperatures from coolers for gas injection, in real time, wherein the temperature control points of the first and/or second stage cooler discharges are automatically controlled by a process controller in order to push heat produced by adiabatic compression to a third or final compression stage. In this way, discharge temperatures at the final stage are elevated to maintain injection gaseous mixtures in vapor phase.
