摘要

Particulate contamination in a hydraulic system fluid is generally considered thernmost important factor governing the reliability and life of the system components.rnModern hydraulic systems demand cleaner fluid and better filtration performance,rnand this drives filter manufacturers to continuously make improvements to theirrnproducts. It has long been recognized that cyclic, or unsteady flow has arnsignificant deleterious impact on filter performance. Since hydraulic systemsrnnormally generate cyclic flow, filters are subject to these flow variations, andrnshould be designed to maintain consistent particle capture and retentionrnefficiency such that the effluent fluid cleanliness target is met.rnThe normal Multi-pass test procedure, ISO 16889, cannot measure the effects ofrnflow variations; therefore, the Cyclic Stabilization Test was developed andrnadopted as SAE ARP4205. The SAE procedure also introduces a new methodrnfor rating filter performance that enables discrimination between filters underrncycling conditions, thereby giving filter designers a tool for developing a stressresistantrnfilter. This paper details the need for improved filtration and documentsrninvestigations using the SAE procedure to study the performance of a number ofrnhydraulic filter elements as a function of flow cycling, vibration, contaminant, andrntemperature.
