润滑油循环过程中,由于螺杆空压机转速高,油的循环速度快,润滑油在有铜、铁等金属催化剂存在的高温条件下,油品极易老化,且油品处于高温搅拌状态,很容易形成泡沫,如果油位过高(判断油位,在螺杆空压机加载状态下观察油位计更为准确),大量泡沫会进入油分,使得气体通过阻力增大,油耗增加,严重者造成高温、过载喷油等。
4、温控阀动作不良:温控阀作为螺杆空压机设备润滑油路的中枢,性能的优劣直接关系着螺杆空压机的高温与否。温控阀主要控制螺杆空压机的喷油温度,因为较低的喷油温度会使螺杆空压机油分内因为压力露点关系而析出冷凝水,容易产生螺杆空压机润滑油乳化现象,缩短润滑油的使用寿命。当温控阀感温探头测得的油温低于其动作值时(感温元件的动作值有55℃和71℃等),则润滑油从油气桶经油过滤器直接到主机;当温控阀感温探头测得的油温高于其动作值时,内部感温探头顶针动作,推动阀芯打开阀内旁通,使有流经冷却器,冷却后的油经油滤回到主机。
5、油过滤器堵塞:螺杆式空压机的油过滤器一般为旋装式纸质过滤器,过滤精度为12um时有50%的杂质分离率,过滤精度为30um时为99%的杂质分离率,能除去润滑油中的大部分杂质,保证主机正常润滑。油滤内底部有止回安全阀,随使用时间推移,沉积在滤纸上的杂质颗粒会引发压差增大,当达到一定压差值时,旁通阀打开,润滑油不经过过滤即喷入主机,这样确保主机机头足够润滑。但通过旁通阀进油后,润滑油的大量杂质带入主机机头,如不及时处理,会大大缩短螺杆空压机包括轴承的使用寿命。
