RFA系列微型直回式回油过滤器相关说明
本过滤器适用于液压系统回油精过滤，滤除系统中由于元件磨损产生的金属颗粒和密割件的橡胶杂质等污染物，使流回油箱的油液保持清洁。RFA系列微型直回式回油过滤器相关说明
过滤器配有发讯器、旁通阀、液流扩散器。其主要性能特点有：1．过滤器直接安装在油箱盖板上，筒体伸入油箱的油液中，进油口设有螺纹和法兰连接方式，与回油管路连接，管路简单，安装方便。
2．过滤器进油口设有滤芯堵塞发讯器，通过观察发讯器指示表，可以随时了解滤芯堵塞情况，当滤芯堵塞，进油口压力达到0.35MPa时发讯器会发出讯号，此时应立即停机更换滤芯。
3．设计采用直回式滤油，只需旋开上盖，即可更换滤芯或向油箱加油。在滤头侧面设有二只M18x1.5油口，可在任何一处安装发讯器或系统中少量油液回流油箱过滤之用，使更换滤芯和向油箱加油十分方便。
4．当滤芯堵塞，发讯器报警后，若不能立即处理故障，进油口压力升至0.4MPa时，设在滤芯下部的旁通阀便会自动开启，另开油路，以避免过滤器损坏，确保系统照常运行。
5．滤芯采用新犁化纤滤材，具有过滤精度高，通油能力大，压力损失小，纳污量大等优点。
