An assembly configured for insertion into and removal from a bore of a fluid end block in which a plunger is to reciprocate. The assembly comprises a valve cartridge configured for insertion into and removal from the bore as a unit, the valve cartridge comprising a valve cartridge housing having an open end, and a plurality of valves operably connected to the valve cartridge housing, and a packing cartridge, configured for insertion into and removal from the bore as a unit, comprising a packing cartridge housing having a plunger bore, to receive the plunger, that defines a first open end and a second open end of the packing cartridge housing. The valve cartridge housing and the packing cartridge housing are engaged such that the open end of the valve cartridge housing and the first open end of the packing cartridge housing overlap.

A system for detecting wear in a fluid end packing of a reciprocating pump is disclosed. The system includes an insert, a sensor, and a controller. The insert is associated with an annular seal ring of the fluid end packing. The annular seal ring defines a sealing interface with a plunger of the reciprocating pump. The sensor is configured to obtain vibration data associated with the fluid end packing. The controller configured to receive, from the sensor, the vibration data associated with the fluid end packing. Further, the controller is configured to determine, based on the vibration data being within a predefined range of vibration indicative of a contact of the plunger with the insert, that a wear level of the fluid end packing satisfies a wear threshold.

At least one aspect of the present disclosure is directed to systems and methods for a valve assembly for a fluid end of a high pressure fracturing pump. The valve assembly may include a valve member having an engagement surface, the valve member movable between a closed position and an open position. The valve assembly may include a valve seat body including a seating surface that is engaged with the engagement surface of the valve member in the closed position, the seating surface including a recess therein. The valve assembly may include an insert disposed within the recess such that at least a portion of an outer surface of the insert that faces a surface of the recess is spaced apart therefrom when the valve member is in the open position.

A manifold assembly includes a high-pressure section including a module with one or more side inlets and a mounting block assembly including a template mounted on the module, a cavity defined through the template, and one or more brackets disposed in the cavity and configured to support a portion of a piping assembly passing through the cavity.

A valve assembly may include a first valve having a central opening and a guide element connected within the central opening. The valve assembly may include a second valve having a valve stem extending through the guide element to define a protruding portion of the valve stem, and a spring retainer on the protruding portion of the valve stem. The valve assembly may include a spring disposed between the spring retainer and the guide element. The spring may be configured to bias both the first valve and the second valve.

A suction valve control system of a fluid pump, that is configured to discharge fluid during a plurality of discharge cycles, may include a plurality of suction valves for respective cylinders of a fluid end of the fluid pump. The plurality of suction valves may be configured to close during the plurality of discharge cycles in accordance with a normal operation of the plurality of suction valves. The suction valve control system may include a controller configured to cause, responsive to a deactivating event for a cylinder of the respective cylinders, a suction valve of the cylinder to be maintained in an open position throughout one or more discharge cycles of the plurality of discharge cycles, while at least one other suction valve of the plurality of suction valves has the normal operation during the one or more discharge cycles.

A valve cartridge for a fluid pump may include a valve cartridge housing, a fluid cavity defined in the valve cartridge housing, and a valve configured to control flow through the fluid cavity. The valve may include one or more guiding components configured to guide opening and closing of the valve. The valve cartridge may include a wear ring surrounding the one or more guiding components to allow sliding movement of the one or more guiding components along an inner surface of the wear ring.

A hydraulic fracturing pump system may include a hydraulic fracturing pump including a fluid end and a power end, a fluid end controller, mounted to the fluid end, storing a fluid end identifier that uniquely identifies the fluid end, a sensor configured to measure a parameter relating to the hydraulic fracturing pump, and a primary controller communicatively coupled to the sensor and to the fluid end controller. The primary controller may be configured to receive the fluid end identifier from the fluid end controller, obtain measurements from the sensor, generate a report that indicates data based on the measurements, and transmit the report to the fluid end controller.

An automated bleed-off system for a hydraulic fracturing system may include a bleed-off manifold that includes one or more fluid inputs to receive pressurized fluid from the hydraulic fracturing system, a bleed-off line fluidly coupling the one or more fluid inputs to an output, and a plurality of isolation valves to control flow through the one or more fluid inputs and the bleed-off line. The automated bleed-off system may include a valve greasing system that includes a grease reservoir to hold grease, and a grease conduit fluidly coupling the grease reservoir to an isolation valve of the plurality of isolation valves. The automated bleed-off system may include a control system that includes a valve actuator, including an actuation sensor, to control actuation of the isolation valve, and a controller configured to cause actuation of one or more of the plurality of isolation valves to bleed-off pressure via the bleed-off line.

A monitoring system for a hydraulic fracturing pump may include a sensor configured to output a signal based on measurements of a fluid parameter relating to the hydraulic fracturing pump, where the signal has a fixed relationship to a measurement scale. The monitoring system may include a first data receiver and a second data receiver configured to derive the measurements of the fluid parameter using the measurement scale. The monitoring system may include a signal distribution device, without external power, coupled to the sensor, the first data receiver, and the second data receiver. The signal distribution device may be configured to distribute respective input signals to the first data receiver and to the second data receiver, where the respective input signals are based on the signal and have the fixed relationship to the measurement scale.
