A compressor maintenance monitoring and alert system for use with a compressor comprises a sensor unit including a housing, at least one vibration sensor and/or electrical impulse sensor, and a computer processor. The housing is constructed and arranged for being mounted or electrically coupled to the compressor. A processor of a mobile communication device receives compressor data transmitted by the sensor unit over a period of time, processes the received compressor data, determines if the received compressor data meets or exceeds scheduled maintenance tasks included in the look up tables, and displays required maintenance tasks on a display of the mobile communication device.

Systems and methods for monitoring, detecting, and/or intervening with respect to cavitation and pulsation events during hydraulic fracturing operations may include a supervisory controller. The supervisory controller may be configured to receive pump signals indicative of one or more of pump discharge pressure, pump suction pressure, pump speed, or pump vibration associated with operation of the hydraulic fracturing pump. The supervisory controller also may be configured to receive blender signals indicative of one or more of blender flow rate or blender discharge pressure. Based on one or more of these signals, the supervisory controller may be configured to detect a cavitation event and/or a pulsation event. The supervisory controller may be configured to generate a cavitation notification signal indicative of detection of cavitation associated with operation of the hydraulic fracturing pump, and/or a pulsation notification signal indicative of detection of pulsation associated with operation of the hydraulic fracturing pump.

A method that includes an electronic application identifying a downlink sequence for execution by a surface control system of a drilling rig, with the sequence including target output values of a mud pump system and/or a drive system. The method includes instructing the control system to operate in accordance with the sequence. The application receives measured output values of the mud pump system and/or the drive system and calculates differences between the target and measured output values. When the differences are within a level of tolerance, then the application identifies the control system as compliant; and when the differences are greater than the level of tolerance, then the application identifies the control system as non-compliant. The method also includes the application receiving data from a BHA of the drilling rig and determining, based on the data received, if a downlink to the BHA was successful.

A positive displacement reciprocating multi-cylinder pump has a pair of cams and associated bearings and yokes that cooperatively and positively reciprocate the pistons. The fluid flow paths are configured through specially designed intake and outlet manifolds to provide intrinsic cooling of the bearings through specially configured fluid flow paths at distal ends of the pump. An intentional head geometry that is identical for each piston may be readily machined using exterior bores. Each head defines a cylinder, captures both inlet and outlet one-way valves, and provides essential fluid flow paths about the cylinders. All bearings are of the sealed type, and no additional oil baths or the like are required, permitting the pump to be stored, transported, and used in any orientation.

A monitoring device is attached to a first leg portion and detects vibration generated in the first leg portion. The monitoring device includes a sensor unit including an inertial sensor, a plate for attachment of the sensor unit, a spacer in contact with the first leg portion, and a bolt for fixation, and is attached to the first leg portion by the bolt with the spacer, the plate, and the sensor sequentially stacked and the spacer is softer than the plate.

Disclosed is a status monitoring and fault diagnosis system for a plunger pump, including a monitoring and fault diagnosis device. The monitoring and fault diagnosis device monitors and diagnoses a hydraulic end assembly of a plunger pump. The monitoring and fault diagnosis device further monitors and diagnoses a power end assembly and/or a reduction gearbox assembly. Beneficial effects: The diagnosis system monitors and diagnoses not only a hydraulic end assembly, but also a power end assembly and/or a reduction gearbox assembly, that is, an equipment fault can be accurately predetermined in time for an entire plunger pump, so that high-pressure, large-displacement, and continuous operation requirements on fracturing sites at present are better satisfied, and on-demand maintenance is adopted instead of regular examination and maintenance, thereby saving labor, time, and materials to achieve economic efficiency.
