滤油器的寿命受系统参数(滤芯尺寸、工作条件和污染程度)变化的影响.因而,正确地预测滤油器寿命常常是很困难的.为此,(美国)Parker Hannifin有限公司以滤油器的污物滞留能力和污物进入系统的速度为依据,提出了一种切实可行的估算方法.在现场工作条件下,滤油器的滤污能力依赖于:1.油液中污物颗粒尺寸的分布;2.通过滤油器的流量;3.油液的粘度; The lifespan of the oil filter is affected by changes in system parameters (filter size, operating conditions, and contamination levels), so it is often difficult to predict the correct life of the oil filter. To do this, Parker Hannifin (USA) Based on the speed of dirt into the system, based on the proposed a practical method of estimating the working conditions in the field, the filter capacity of the filter depends on: 1. Oil particles in the dirt The size of the distribution; 2 flow through the oil filter; 3 oil viscosity;
