    Abstract: A monitoring system may include a position sensor, strain gauges, and a computing device for monitoring valves in a pressure pump having multiple chambers to determine critical valve limits for the valves using strain measurements for each charmber. The strain gauges may determine strain in each chamber of the pressure pump. The position sensor may determine the position of a crankshaft mechanically coupled to a plunger in each chamber. The computing device may receive signals generated by the strain gauges and the position sensor related to the strain in each chamber and the position of the crankshaft, respectively, and may process the signals to determine delays in the actuation of the valves for determining critical valve limits.

    Abstract: A method for monitoring a condition of at least one valve positioned with respect to at least one of a first chamber and a second chamber of a reciprocating compressor is provided. The method includes establishing a compressor operation cycle including a valve opening event, a valve closing event and/or a rod reversal event. A crank angle is determined at each of the valve opening event, the valve closing event and/or the rod reversal event during the compressor operation cycle using at least one of a static pressure input and a machine speed input. The method further include diagnosing a valve leak condition during the compressor operation cycle at the valve closing event, wherein the at least one valve is closed.

    Abstract translation: 提供了一种用于监测相对于往复式压缩机的第一室和第二室中的至少一个定位的至少一个阀的状态的方法。 该方法包括建立包括阀打开事件，闭阀事件和/或杆反转事件的压缩机操作循环。 在压缩机运行循环期间，使用静压输入和机器速度输入中的至少一个，在阀打开事件，闭阀事件和/或杆反转事件中的每一个确定曲柄角。 所述方法还包括在所述关闭阀门事件期间在压缩机运行循环期间诊断阀泄漏状况，其中所述至少一个阀关闭。
