    Abstract: 本发明提供一种增压泵的输出电压控制方法,该方法包括:检测增压泵的运行参数,根据该增压泵的运行参数调整增压泵的输出电压。本发明还提供一种增压泵的输出电压控制装置。由于增压泵的输出电压的变化将使得增压泵的转速发生变化,增压泵的转速发生变化将使得增压泵的出水压力发生变化,因此,通过调整增压泵的输出电压,能够有效的实现对增压泵的出水压力的调整,实现对增压泵的出水压力的控制。

    Abstract: 本发明提供在发动机负荷增大时抑制发动机的转速过度跌落,并且可靠性较高的液压驱动系统。油压驱动系统(1)具备:发动机(E);可变容量型的油压泵(17L、17R);倾转角调节装置(20);转速传感器(22);和控制装置(30)。控制装置(30)控制倾转角调节装置(20)的动作,以使油压泵(17L、17R)的泵转矩达到目标指令转矩的形式改变油压泵(17L、17R)的排出容量。又,控制装置(30)在将泵转矩提升至目标指令转矩时,如果由转速传感器22检测出的发动机E的实时转速小于控制开始转速,则使泵转矩以预先设定的上限变化率以下的变化率从小于目标指令转矩的待机转矩上升至目标指令转矩。

    Abstract: A two (or more) piston pump system (10) is provided with both pumps (12) being crank (14) driven. The system does not have a mechanical camshaft, but a software algorithm, which acts like one in controller (20). The algorithm will LEARN and create a unique speed profile, which will mimic the mechanical camshaft. For practical purposes the speed profile of output gear is called Cam profile with software acting as an imaginary camshaft. The algorithm utilizes Crank Angle Estimation, Learn Curve Generation, Smoothing and Advance Timing Calculation.

    Abstract: A compressor controller provides integrated monitoring, control, and alarm capabilities. The compressor controller receives a run signal from a rack controller. Upon receipt of the run signal, the compressor controller monitors startup conditions to determine whether it is safe to start the compressor. If so, the compressor controller applies power to the compressor and determines whether the compressor is running properly. Once the compressor is running properly, the compressor controller continues to monitor the operation of the compressor. If the compressor controller detects a fault conditions during the startup or operation of the compressor, the compressor controller provides an alarm signal and shuts down the compressor if necessary. The compressor controller provides maximum protection for the compressor by monitoring a plurality of relevant conditions and by shutting the compressor down when necessary. The compressor controller also maximizes the compressor's availability by evaluating the monitored conditions to determine whether the compressor can continue to run or be restarted despite a fault condition.
