二十四.SRFA系列双筒微型直回式回油过滤器(新型)

SRFA DUPLEX TANK MOUNTED MINI-TYPE RETURN FILTER SERIES

(一)性能用途

它被安装在油箱顶部,可在系统不停机的情况下更换滤芯,适用于连续工作的液压系统回油精过滤,用来滤除液压系统中诸元件磨损产生的金属粉末以及密封件的橡胶杂质等,使流回油箱的油液保持清洁,以利于系统中的油液循环使用。

    当一只过滤器的滤芯堵塞致使进出口压差为0.35MPa时,发讯器发讯,这时,转动换向阀,使备用滤油器工作,然后更换已堵塞的滤芯。在因故不能及时更换已堵塞滤芯,使进出油口压差进一步上升到0.4MPa时,因设计采用了直回滤油,从而更换滤芯或向油箱加油变得非常方便,只需旋开过滤器滤盖即可更换滤芯或向油箱加油,每个滤头设有2只M18×1.5油口,可在任何一处安装发讯器。

    扩散器设置在回油筒体底部,能使回油的介质平稳地流入油箱内,不易产生气泡,减少了空气的重新进入,并减弱已沉积污染物的骚动。滤芯采用新型化纤过滤材料,具有过滤精度高、通油能力大、原始压力损失小、纳污量大等优点,其过滤精度以绝对过滤精度标定,过滤比β3、5、10、20>100,过滤效率n≥99%,符合ISO标准。

INTRODUCTION

      The SLHN  series filter is composed of two single bowl filters  and a 2-position 3-way dir-ectional valve.it is simple in structure and easy to use .it  is mounted on tank top , There is
by-pass valve and  contamination indicator in it, for protecting the hydraulic system safety.

      The feature of this filter allows continous operation even  during  replacing element which is clogged by contaminant. Turn the directional valve,the  other filter will be working in the hydraulic system,the cloogged element should be changed in that time.

      This series filter is widly used in the hydraulic systems of heavy duty, mining and  metallur gical machinary.
