    Abstract: A pressure relief valve has a housing fluidly connected to a pressurized system line carrying a system fluid. The housing carries a moveable piston and a valve member that both move between closed and open positions. The piston defines an upper chamber and a lower chamber within the housing. A pressurized fluid is supplied to the upper chamber to bias the piston toward the closed position. After the relief valve opens from excessive system pressure, the pressurized fluid is injected into the lower chamber to delay the return of the piston to the closed position. Initially, the fluid in the lower chamber flows through a check valve while the piston returns to the closed position. Then the fluid vent in the lower chamber vents from the lower chamber as the piston and valve member approach the closed position.

    Abstract: A suction cover for a reciprocating pump assembly includes a plug configured to be at least partially received within an access port of a fluid cylinder of the reciprocating pump assembly. The plug includes at least one key configured to be received through a keyhole of the access port such that the at least one key extends within a keyway of the access port when the plug is at least partially received within the access port. The plug is configured to be rotated within the access port between an unlocked position wherein the at least one key is aligned with the keyhole and a locked position that prevents the plug from backing out of the access port.

    Abstract: A monitoring apparatus is adapted to monitor lubricant in a hydraulic fracturing pump system, and includes a gateway and one or more sensors configured to be in communication with the gateway. The one or more sensors are configured to measure quality of the lubricant, a pressure of the lubricant, and a temperature of the lubricant. The gateway is configured to receive sensor data associated with the quality of the lubricant, the pressure of the lubricant, and the temperature of the lubricant. To monitor the lubricant, the gateway is configured to: store the sensor data on the non-transitory computer readable medium; transmit to another computing device the sensor data and/or representative data based on the sensor data; visually indicate a status of the quality of the lubricant; visually indicate a status of the pressure of the lubricant; visually indicate a status of the temperature of the lubricant; or any combination thereof.

    Abstract: A valve seat at least partially formed of a ceramic material for use in a fracturing pump includes a first body and a second body. The first body is configured to be inserted into a fluid passageway of the fracturing pump. The first body has an outer diameter, D1. The second body extends radially from the first body and has an outer diameter, D2, greater than the outer diameter, D1, of the first body. The second body is at least partially formed of the ceramic material.

    Abstract: According to one aspect, a manifold assembly includes a skid, a low pressure manifold connected to the skid, and a high pressure manifold connected to the skid. In another aspect, the high pressure manifold has a modular configuration so that the high pressure manifold is disconnectable in whole or in part from the skid, and reconnectable in whole or in part to the skid. In yet another aspect, the high pressure manifold includes high pressure modules, all of which are in fluid communication with each other and each of which is adapted to be in fluid communication with at least one pump. In still yet another aspect, the low pressure manifold includes one or more flow lines, the high pressure manifold includes fittings, and the manifold assembly includes vibration isolators to dampen dynamic loading, the vibration isolators being disposed between the fittings and the one or more flow lines.

    Abstract: A valve seat for use in a fluid end of a fracturing pump that includes a first body portion having an inner wall and an outer wall, wherein the inner wall forms a fluid bore and outer wall is configured to contact an inside surface of a fluid passageway of a fluid end of the fracturing pump for support therein. The seat further includes a second body portion extending from the first body portion, the second body having a frustro-conical portion forming a seating surface for receiving a valve. A portion of the first and second body portion includes a hardened material insert forming a portion of the seating surface and a portion of the inner wall of the first body, and further includes a metallic body portion affixed to the hardened material insert, the metallic body portion forming at least a portion of first body portion outer wall.

    Abstract: A dual circuit lubrication system for a power end of a reciprocating pump that includes a lubrication pump that supplies lubrication fluid to a high pressure lubrication circuit and a low pressure lubrication circuit. The high pressure lubrication circuit is fluidly coupled to a crankshaft to supply lubrication fluid to journal surfaces associated with the crankshaft at a first lubrication fluid pressure. The crankshaft drives a crosshead coupled to a plunger to displace fluid from a fluid end of the reciprocating pump. The low pressure lubrication circuit is fluidly coupled to supply the lubrication fluid to a plurality of roller bearing surfaces associated with the crankshaft at a second lubrication fluid pressure. The first lubrication fluid pressure is greater than the second lubrication fluid pressure.
