摘要： A system for detecting leakage in a pump includes a first pressure sensor, a second pressure sensor, multiple third pressure sensors, and a controller. The first pressure sensor is configured to output a pressure value associated with a suction manifold of the pump. The second pressure sensor is configured to output a pressure value associated with a discharge manifold of the pump. The third pressure sensors are configured to output a pressure value associated with the cylinders of the pump. The controller is disposed in communication with the first pressure sensor, the second pressure sensor, and the third pressure sensors. The controller is configured to determine amplitude of a leak, and a location of the leak in the pump on the basis of pressure values received from the first pressure sensor, the second pressure sensor, and the third pressure sensors.

摘要： A method for identifying a mode of failure in a pump includes receiving and recording a first set of flow rate pressure values over a specified time period to determine an existing hydraulic signature of the pump. The method then includes receiving and recording real-time flow rate pressure values over a subsequent period of time to determine a current hydraulic signature of the pump. The method further includes comparing the real-time flow rate pressure values to the first set of flow rate pressure values to detect variances in the hydraulic signature and output a mode of failure for the pump.

摘要： A prognosis and diagnosis system for a pump includes a reference dataset, a historical dataset, a data acquisition engine (DAE), and a comparison engine. The reference dataset includes theoretical values obtained for at least one performance parameter pertaining to the pump. The historical dataset includes data values for the at least one performance parameter based on historical performance of the pump when the frac rig pump was operating under healthy and normal operating conditions. The DAE is configured to obtain real-time values for the at least one performance parameter that are measured during a current operating condition of the pump. The comparison engine is configured to selectively output a mode of failure based upon a comparison between the real-time values and at least one of the theoretical values from the reference dataset and the data values from the historical dataset.

摘要： A cost configurable drive system for machines having dual/tandem axle drive systems employs a split hystat power system. The system performance can be easily adjusted by the removal or installation of a planetary gear set and a clutch box. In this way, the system is configurable with components removed or substituted to allow for a less capable but lower cost offering, while allowing for very simple upgrade to a fully capable system.

摘要： A hybrid engine assembly may include an engine having a crankshaft, a supplemental shaft mechanically coupled to the crankshaft, a flywheel energy storage assembly, and an auxiliary device. A flywheel clutch may selectively couple the flywheel assembly to the crankshaft. The assembly may be selectively operated in an engine restart mode by directly coupling the flywheel energy storage assembly to the crankshaft prior to starting the engine, and in an auxiliary power mode by directly coupling the flywheel energy storage assembly to the auxiliary device.

摘要： A hybrid construction machine is provided. The machine includes a prime mover, at least one fluid pump, at least one fluid actuator, a swing motor, a first flywheel, and a second flywheel. The prime mover drives the at least one fluid pump. The fluid pump provides pressurized fluid to drive the at least one fluid actuator. The returning fluid from the at least one fluid actuator can be used to drive a swing motor, which in turn drives a swing structure. Further, the second flywheel is also coupled with the prime mover. The second flywheel can be configured to store the energy when the prime mover is driven by the at least one fluid pump. The at least one fluid pump is driven by the return fluid from the at least one fluid actuator.

摘要： A drivetrain system is disclosed for use with a machine having a work tool. The drivetrain system may have a transmission with a plurality of clutches. The drivetrain system may also have an input device movable by an operator to generate a first signal indicative of a desired selection of a park setting or one of a plurality of travel settings, a sensor configured to generate a second signal indicative of loading of the work tool, and a controller in communication with the input device, the sensor, and the transmission. The controller may be configured to anticipate completion of a loading cycle based the second signal, and to selectively cause at least a first of the plurality of clutches to engage in a combination that produces one of the plurality of travel settings based on the anticipated completion of the loading cycle, notwithstanding the desired selection from the input device being the park setting.
