1 Scope This document describes two methods to measure in repeatable conditions the filtration efficiency of filter elements used in aviation and aerospace hydraulic fluid systems. It can be applied when evaluating the overall characteristics of a filter element according to ISO 14085‑1, or separately. Since the filtration efficiency of a filter element can change during its service life as it is clogging, this test method specifies its continuous measurement by using on-line particle counters with continuous injection of test contaminant and recirculation of particles not retained by the test filter element until the differential pressure across the element reaches a given final or “terminal” value. This document allows the efficiency to be measured under both steady or cyclic flow conditions. It is also applicable to measuring the stabilized contamination levels that are produced by the filter element while testing with cyclic flow . This document is not applicable to qualifying a filter element under replicate conditions of service; this can only be done by a specific test protocol developed for the purpose, including actual conditions of use, e.g. the operating fluid or contamination. The test data resulting from application of this document can be used to compare the performance of aerospace hydraulic filter elements.
吸油过滤器的主要性能指标具体介绍如下:1.过滤精度过滤精度是指过滤器对不同尺寸颗粒污染物的滤除能力,常用绝对过滤精度 吸油过滤器价格,过滤比和过滤效率等指标来评定,过滤精度分为粗(d≥0.1mm)、普通(d≥0.01mm)、精(d≥0.005mm)、和特精(d≥0.001mm)四个等级。2.纳垢容量过滤器在压力降大于其规定限值之前截留的污染物的问题称为纳污容量,以重量(g)表示。...
与相匹配的滤芯直接互换严格的质量管理系统保证了滤芯在长度,直径和密封面上的尺寸误差ParFit 替换滤芯的过滤效率与原始滤芯的效率相当或防腐蚀端盖和全粘合结构保证了大强度符合所有制造和试验的ISO标准价格具有竞争力具有成本效益的全系列、优质滤材选择可与大多数液压油和润滑油兼容Parker 过滤器、配件和增值服务为全方位的滤波器应用提供了节省成本的解决方案。...
如重复使用时,需明确其规程并进行管理和控制,以确保设备的安全和有效,确保其一直符合制造商的规格和使用要求,并进行重复使用的相关测试和验证。 重复使用滤芯的细菌截留测试是针对重复使用后滤芯的一项细菌截留测试,考察重复使用后的滤芯是否还有细菌截留能力,评价细菌穿透的风险。...
因此β值越大,则该过滤器的过滤效率也越高。贺德克HYDAC滤芯的主要特性由于名义精度不能真实的反映贺德克HYDAC滤芯的过滤能力,因此,常以在规定的实验条件下过滤器可以通过的zui大硬质球形颗粒的直径作为其过滤精度,用以直接反映新装滤芯初期的过滤能力。...
