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。
