    摘要： A pumping control unit is disclosed herein. The pumping control unit includes a processor coupled to a memory and a communication interface. The memory is configured to store an invariant matrix. The communication interface is configured to receive a plurality of measurements of a time-varying parameter for a rod pumping unit. The plurality of measurements is taken at a surface of a pumping site over a pump cycle for a sucker rod string. The processor is configured to gain access to the invariant matrix in the memory and the plurality of measurements from the communication interface. The processor is further configured to compute a Fourier coefficient array based on the invariant matrix and the plurality of measurements. The processor is further configured to compute a time-varying downhole parameter based on the Fourier coefficient array and a sucker rod string model.

    摘要： An air compressor comprising: a tank (50), a compression mechanism (30), a motor (5) and a control circuit (7). The control circuit (7) includes a CPU (70) and a storing unit (74) which stores a control program, the compressor operation history and a plurality of operation modes. Each of the operation modes is defined by two setting values: a reference restart pressure value and a motor rotational speed value, at least one of these values being different from among the plurality of modes. The control circuit (7) executes one of the plurality of modes as a target mode in which the control unit controls the motor to restart by comparing the pressure in the tank with the reference restart pressure and rotates the motor at the rotational speed of the target mode. The control circuit changes the target mode from the one of the plurality of modes to another one of the plurality of modes based on the compressor operation history.

    摘要： An electric oil pump for supplying oil to at least a part (a clutch) of a transmission is provided in parallel with a mechanical oil pump which is driven by an engine and supplies oil to each part of the transmission. In advance of an operation request to the electric oil pump, the electric oil pump is rotated at a first operation-preparation rotational speed which is a very low speed so as to replace oils in oil pipes controlled by the electric oil pump. Thereafter, the electric oil pump is rotated at a second operation-preparation rotational speed which is a relatively-high speed, and when an actual rotational speed reaches the second operation-preparation rotational speed, it is determined that operation preparation is completed.

    摘要： A variable capacity hydraulic machine has a rotating group located within a casing and a control housing secured to the casing to extend across and seal an opening in the casing. The control housing accommodates a control circuit and a pair of sensors to sense change in parameters associated with the rotating group. One of the sensors is positioned adjacent the barrel on the rotating group to sense rotational speed and the other senses displacement of the swashplate. The control housing accommodates a control valve and accumulator to supply fluid to the control valve.

    摘要： A method and a system for determining a setting parameter of a hydrostatic displacement unit is provided. In the method, a pressure value, a rotational speed value, and a torque value are determined. The setting parameter can be determined with use of the pressure value, rotational speed value, torque value of the setting parameter characteristic diagram, and a setting parameter characteristic diagram, which is an inverted efficiency characteristic diagram, which has at least pressure, rotational speed, and torque as input parameters. The system can include a system unit for determining a pressure value, a system unit for determining a rotational speed value, a system unit for determining a torque value, and a system unit for determining the setting parameter with use of the pressure value, rotational speed value, torque value, and a characteristic diagram, whereby the system for determining a setting parameter is formed so that during the determination of the setting parameter it can use as a characteristic diagram a setting parameter characteristic diagram, which is an inverted efficiency characteristic diagram or torque characteristic diagram, which has at least pressure, rotational speed, and torque as input parameters.
