过滤分离主要基于以下三种机理 直接拦截 惯性撞击 扩散拦截

直接拦截 : 液体中的基本过滤机制，本质是一种筛分效应，机械拦截颗粒，当颗粒大于流道孔径时即被该结构去除，通过搭桥作用,尺寸小于滤孔的颗粒也可被拦截，

惯性撞击:尺寸小于滤材孔径的颗粒的辅助拦截方式，流体携带的颗粒由于质量和线速度而具有直线运动的惯性，颗粒离开流体主流而撞击到滤材上，当流体改变运动方向时,惯性使颗粒撞击到滤材表面, 因吸附力的存在颗粒便停留在撞击表面。当流经过滤介质时流体必须沿弯曲通道行进.这将增加该过滤机理的有效性。

过滤介质的过滤/分离效率由于直接拦截 惯性撞击 扩散拦截的共同作用而增强。

滤芯的操作与维护

■ 当油温 >10℃时，风力发电机组工作。

■ 当油温 40℃，过滤器进出口的压差超过 3bar 时，压差发讯

器发出报警信号，提示更换滤芯。当油温≤ 40℃时，忽略从压

差发讯器传来的报警信号。

■ 当油温＞ 55℃时，油流经冷却器的进行冷却，当油温降至

45℃时，油直接流入齿轮箱。

■ 泵出口压力传感器或压力表，用于检测系统的压力，系统

安全阀设定压力为 12bar，当检测压力超过 12bar 时，安全

阀打开，系统溢流。

■ 齿轮箱入口处的压力传感器的监测范围为

0.8 ～ 6bar，不在此范围内时报警（油温 70℃时

压力≥ 0.8bar，油温低于 10℃时压力≤ 6bar）（此

监控范围为主机制造商根据实际需要设定，仅供参

考）；或采用压力继电器监测压力，若压

力＜ 0.8bar 时，报警持续超过 5 秒则停机。
