在油压装置中设置过滤器的目的就是除去污染物。油压装置的故障80～90%是由于污染物产生的。油压装置的故障大致可分为突发性故障和劣化故障两种。突发性故障大多是由15μm 以上的污染物,即尖片状的污染物引起的。劣化故障主要是由于缓慢磨损等使机械性能降低到允许的限度以下,由5μm 以下的粉砂污染物造成这种故障的情况很多。对运转中的油压机械的污染物的调查表明:油压系统中存在大量的污染物,由于这些污染物使油压装
The purpose of the filter in the hydraulic unit is to remove the contaminants. 80 to 90% of the hydraulic device failure is due to contaminants. Hydraulic equipment failure can be divided into two kinds of sudden failure and deterioration. Sudden failures are mostly caused by contaminants of more than 15 μm, ie, sharp-edged contaminants. Degradation failures are mainly caused by the slow wear and other mechanical properties below the allowable limit, often caused by the silt contaminants below 5μm. A survey of the contaminants in the hydraulic machinery in operation shows that there are a large number of contaminants in the hydraulic system,
