ISO 23181:2007规定了一种方法,用于确定液压滤芯在高粘度流体中的流动疲劳阻力,该方法使用均匀变化的流速,达到预定的终端压差和受控波形。
它建立了一种方法,用于验证滤芯承受由可变流量引起的循环压差引起的挠曲的能力。
ISO 23181:2007 specifies a method for determining the resistance of a hydraulic filter element to flow fatigue when subjected to high viscosity fluid, using a uniformly varying flow rate up to a predetermined terminal differential pressure and a controlled waveform.
It establishes a method for verifying the ability of a filter element to withstand the flexing caused by cyclic differential pressures induced by a variable flow rate.
