摘要： A controlling device ensures an accurate control of the rotational speed of an engine. When a hydraulic working machine is in a suspended state, the rotational speed of the engine can be changed from a designated rotational speed to a low rotational speed without requiring any specific manipulation by the operator. When all control levers 14 to 21 are shifted to their respective neutral positions to suspend the operation, and the shifting speed of the control lever which is lastly shifted to its neutral position is low, a delay time is set to be longer than in the case of high shifting speed. If the control levers 14 to 21 are maintained in their respective neutral positions after the elapse of the delay time, the engine 1 is changed to the low rotational speed mode. When one of control levers is shifted before the elapse of the delay time, the engine 1 is continuously maintained in the designated rotational speed mode.

摘要： A pumping system pumps material downhole, for example, to perform a fracturing operation. The pumping system comprises one or more variable speed engines, one or more variable displacement hydraulic pumps and one or more intensifiers. According to the desired or required load, the speed of the engine is set at an optimal or most efficient operating speed. The volumetric displacement of the variable displacement hydraulic pump is set to provide the desired output volume and pressure of the material from the intensifier. Varying the speed of the engine and the volumetric displacement of the variable displacement pump allows for the pumping system and in particular the engine to operate at an optimal efficiency which reduces at least fuel costs and wear and tear on components.

摘要： A method for optimizing the operating efficiency of a compressor having a compression module for compressing a fluid, the compression module including an inlet for receiving the fluid and an outlet for discharging compressed fluid, the compressor including a prime mover for driving the compression module and a rotatable fan for drawing ambient air into the compressor. The compressor includes a first temperature sensor for sensing the temperature of compressed fluid discharged from the compression module, a second temperature sensor for sensing the temperature of a coolant circulating through the prime mover, a third temperature sensor for sensing the temperature of the fluid entering the compression module, and a fourth temperature sensor for sensing the temperature of a lubricant mixed with the fluid as the fluid is compressed in the compression module. The compressor includes an electronic control module (ECM) electrically connected to the four temperature sensors for receiving signals therefrom. The ECM includes a non-volatile memory containing empirical data relating to optimal operating set points of the compressor and a logic routine for controlling the rotational speed of the fan and the volume of the lubricant mixed with the fluid so as to optimize the efficiency of the compressor. The method includes the steps of executing a temperature sensing subroutine whereby the first, second, third and fourth temperature sensors collect temperature data and relay the temperature data to the ECM, executing a fan speed subroutine whereby the ECM generates signals in response to the temperature data received by the ECM for controlling the rotational speed of the fan, and executing a lubricant volume control subroutine whereby the ECM generates signals in response to the temperature data received by the ECM for controlling the volume of the lubricant mixed with the fluid in the compression module.
