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。
滤芯更换及清洗
过滤器底部的滤头上装有压差发讯器，当过
滤器内的滤芯压差达到 3bar 时，压差发讯
器发出开关信号给主机控制系统，并由主机
控制系统发出警报，以提示更换滤芯（油温
低于 40℃报警信号被忽略）。
过滤的定义:利用有孔介质从流体(液体或气体)中除去污染物
精度的定义:
在***试验条件下能够通过过滤器的刚性球形颗粒的直径，它是过滤器元件中开孔的标志。
高效过滤芯
滤除固体污染物速度快、*** ( βx(c)) ≥ 1000)滤材由纤维纤维和树脂通过***工艺制成，具有固
定的空隙结构，滤材无脱落。被拦截的污染颗粒不，会因压差和流量的脉动而产生 " 卸载 " 现象。深层滤材 , 高容污空间 , 过滤器使用寿命长。采用螺缠带***的支撑，***滤材稳固
***技术的打褶设计■ 使用滤面积化■ 增加流量处理能力■ 更小滤芯外形■ 创造均匀的流量分布
抗冲击疲劳滤材■ 提高流体清洁度的稳定性■ 提高现场恶劣条件下的过滤性能
