摘要： Systems and methods for operating hydraulic fracturing units, each including a hydraulic fracturing pump to pump fracturing fluid into a wellhead and an internal combustion engine to drive the hydraulic fracturing pump, may include receiving signals indicative of operational parameters. The systems and methods also may include determining an amount of required fracturing power sufficient to perform the hydraulic fracturing operation, determining an available power to perform the hydraulic fracturing operation and a difference between the available power and the required power, and controlling operation of the hydraulic fracturing units based at least in part on the power difference. When the power difference is indicative of excess power available, the system and methods may include causing at least one of the hydraulic fracturing units to idle, and when the power difference is indicative of a power deficit, increasing a power output of at least one of the hydraulic fracturing units.

摘要： A bellows pump device includes a control unit which, before operation of the bellows pump device is started, performs initial control in which solenoid valves are switched and pressurized air is supplied to suction-side air chambers in advance, thereby determining operation air pressures which are air pressures of the pressurized air to be supplied to the suction-side air chambers during the operation. As the initial control, the control unit outputs control commands to electropneumatic regulators so as to gradually increase the air pressures of the pressurized air to be supplied to the suction-side air chambers in advance, and when detection signals resulting from detection of expansion positions of the bellows are inputted from the proximity sensors to the control unit, the control unit determines the air pressures of the pressurized air supplied to the suction-side air chambers at that time as the operation air pressures.

摘要： The purpose of the present invention is to provide an air compressing apparatus capable of establishing a sufficient air-filling rate while reducing noise at the initiation of operations. To solve this problem, in the present invention, the air compressing apparatus comprises a compressor body that compresses air, a motor that drives the compressor body, an inverter that controls the rotation speed of the motor, a control circuit connected to the inverter, and a pressure sensor that detects the pressure of air compressed in the compressor body, wherein the control circuit controls operation of the compressor body by operating at a low speed activation mode that operates the compressor body at a low speed rotational frequency lower than a maximum rotational speed when the air compressing apparatus is activated, and on the basis of a pressure value detected by the pressure sensor and elapsed time from activation, switching from the low speed activation mode to a normal operating mode that operates at variable frequencies including a maximum rotational frequency.
