               常见螺杆空压机高温概况

 



        空压机运行高温现象是售后服务过程中常见问题之一,空压机主机排气温度是影响空压机安全、可靠、稳定运行的重要因素。很多空压机运行超温在夏天是一种常见现象,因此往往不能引起空压机管理人员的重视。高温的发生不仅影响生产,还会加剧设备的损耗,缩短其正常使用寿命。此外高温还会加速空压机油劣化,润滑性能降低、闪点下降等,有时高温还会在内外因共同作用下引发油品自燃,导致空压机烧毁,甚至发生爆炸事故。因此,高度重视设备运行中出现的高温问题,及时消除隐患,保障生产用气要求。

     空压机设备正常排气温度处于75℃ —95℃ 之间,排气温度低于压力露点时会产生结露现象,使系统内出现较多的水分,导致润滑油乳化,影响润滑效果。严重者可能会因为冷凝水较多,使油气桶内的润滑油因为比重关系全部排入空气管网中。这不但增加后处理难度,而且会使主机轴承不能及时得到润滑而烧毁,最终导致主机故障。而高排气温度,使压缩机为考虑膨胀而预留的间隙增大,高泄漏让压缩机的效率降低,导致电能消耗依旧,而产气量却下降。温度过高还会使润滑油在金属的催化下出现热分解,生产有害的游离碳和酸类物质,导致积碳淤积,堵塞油路,严重者会使主机结焦卡死。尽管螺杆空压机设计有高温保护(105或110℃ 自动停机),但还是要谨慎对待空压机长期高温问题(本公司微官网里有专门文章论述螺杆机油超温问题)。

三、冷却水、冷却风量不足。

     查看冷却水水温高低,水温高使得冷却水与润滑油间的温度缩小,降低换热效果;另外,冷却水量不足,高温润滑油的热量不能及时被循环冷却水降温,导致温度越来越高。通常要求冷却水回水水压不低于0.15MPa.

大乐透综合走势图        润滑油在保养周期内,随时间推移会有所损耗,此时因为油气桶内油量减少,设备运行温度会有所增高。根据运行油位计指示,达到最低限时,就需要停机补充润滑油,润滑油的连续补给, 并不会改善其劣化状态,因此若压缩机到达油品更换周期,需全部排空更换压缩机专用润滑油。压缩机如在多粉尘及高温环境下运行,换油周期应视具体情况提前更换(正常工况下换油周期是2000小时的,建议缩短到1000—1500小时;正常工况下换油周期是4000小时的,建议缩短到2000—2500小时;其他换油周期的以此类推)。

      在条件许可的情况下,压缩机润滑油可以采用定期抽验的方法,根据油样结果酌情是否更换。一般压缩机设备运行一年左右,建议对压缩机整个油路系统做一次系统在线清洗,有条件的用户每次换油前做一次系统在线清洗;在线清洗剂类似保健品,它的消费对象是螺杆压缩机整机养护,随着螺杆压缩机的日益普及,由于螺杆压缩机保养知识的缺乏,处于亚健康的螺杆压缩机也越来越多,螺杆压缩机在线积碳清洗剂也就应运而生,在线清洗剂由于其免拆卸、方便使用、提升设备效率等优点,很快被市场接受,但要明确的是:在线积碳清洗剂只有在每次压缩机换油时,坚持使用才能减少油路结焦积碳几率!若主机机头和油路已经严重结焦积碳,就必须改用线下采用溶剂型清洗剂清洗(主机、油管、冷却器拆下来浸泡或外力循环清洗,油气桶底部胶状物浸泡刷洗)。

二、温控阀动作不良

三、油过滤器堵塞

      螺杆式压缩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,会大大缩短压缩机包括轴承的使用寿命。

四、高压胶管和二次回油管路
