Embodiments of vibration damping clips for use within a climate control system are disclosed. In an embodiment, a vibration damping clip is engaged with three fluid lines of an outdoor unit of the climate control system, such as, for instance, a suction line of a compressor of the climate control system, a discharge line of the compressor, and a fluid line coupled to a pressure equalization valve (PEV) within the outdoor unit.

According to an embodiment, an apparatus for detecting a characteristic of a pump includes: a housing having a first planar surface and a second planar surface opposite the first planar surface, a mount structure located on the second planar surface, wherein the mount structure is configured to facilitate attachment of the apparatus on an external surface of the triplex pump, and wherein the mount structure avoids penetrating an inside surface of the triplex pump. Advantageously, apparatus is a non-invasive device and does not involve modifications to the pump nor opening the lid of the pump.

A pump control system and an abnormal processing and recovering method thereof are disclosed. The pump control system includes a pump; a motor mechanically connected to the pump; and a driving controller electrically coupled to the motor, and the driving controller configured to control a speed of the motor. The driving controller controls the speed of the motor to be varied in a multistage manner in response to an abnormal triggering event, so as to recover the pump control system to an originally set stable state. The abnormal triggering event is generated by at least one physical parameter when the pump control system is operated.

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 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.

A hydraulic pumping method for use with a subterranean well can include mounting a hydraulic actuator above a wellhead, the hydraulic actuator and the wellhead being axially aligned with each other and inclined relative to vertical The hydraulic actuator can be unsupported by any substructure or guy wires after the mounting. A hydraulic pumping system for use with a subterranean well can include a hydraulic actuator including a piston that displaces in response to pressure in the actuator, a magnet that displaces with the piston, and a magnetic field sensor that detects a presence of the magnet. The hydraulic actuator may be mounted above a wellhead, with the hydraulic actuator and the wellhead being axially aligned with each other and inclined relative to vertical.

A pumping method can include displacing a rod string with pressure applied to an actuator by a pressure source including an accumulator and a separate gas volume in communication with the accumulator. A sensor indicates whether a fluid is in the gas volume. A pumping system can include an actuator, a pump connected between the actuator and an accumulator, a hydraulic fluid contacting a gas in the accumulator, a separate gas volume in communication with the accumulator, and a sensor that detects the hydraulic fluid in the gas volume. Another pumping system can include an actuator, a pump connected between the actuator and an accumulator that receives nitrogen gas from a nitrogen concentrator assembly while a hydraulic fluid flows between the pump and the actuator, a separate gas volume in communication with the accumulator, and a sensor that detects a presence of the hydraulic fluid in the gas volume.

A control system for hermetic cooling compressor includes a reciprocating compressor (3) and an electronic control (2) for the reciprocating compressor (3). The electronic control (2) is configured for, after commanding the turning off of the reciprocating compressor (3), detecting whether the turn velocity (23) of the turning axle (10) is below a predefined velocity level, and then applying a braking torque (36) that causes deceleration of the turning axle (10) before completing the next turn of the turning axle (10), in case the turn velocity (23) detected is below the velocity level (34).

A fracturing apparatus may include a first plunger pump including a first power end and a first hydraulic end; a prime mover including a first power output shaft; and a first clutch including a first connection portion and a second connection portion. The first power end of the first plunger pump includes a first power input shaft, the first connection portion is coupled to the first power input shaft, the second connection portion is coupled to the first power output shaft of the prime mover.

Provided is a dynamic characteristic measurement method for a cylinder block of a non-intrusive axial piston pump. The cylinder block is the main rotating component of the axial piston pump, and the dynamic characteristic of the cylinder block is more capable of reflecting the health condition of the pump than an external characteristic. A non-contact type measurement scheme is provided so as to reduce the influence of a measurement device on the motion of the cylinder block. Cylinder block contour signals and radial displacement signals are obtained by measuring the radial displacement of two sections of the surface of the cylinder block under different working conditions in the perpendicular directions, and then the cylinder block contour signals are accurately removed from the radial displacement signals to obtain the translational and tilting motion characteristics of the cylinder block.
