辽阳干式变压器组增压压力下降是什么故障造成的（1）故障现象 增压压力的变化对机的性能影响较大，也容易察觉。当增压压力降低时，机充气量减少，功率湘江，油耗增高，排气温度升高。因此，发现增压压力下降10%左右时应停机检查。（2）故障原因1）空气弗列加滤清器阻塞。空气弗列加滤清器滤芯沾满尘土而阻塞，导致进气阻力增加，压气机吸气损失增大，将使增压压力下降。此时，应及时保养空气弗列加滤清器。2）压气机通到脏污。空气弗列加滤清器除尘效果欠佳，灰尘和润滑油等粘附在涡轮霍尔塞特涡轮增压器（Holset ）的叶轮和扩压器的通道上，使气流阻力增加，导致压气机效率及增压压力下降。为防止这种现象，应保持空气弗列加滤清器的滤清效果，并定期拆洗压气机。3）中冷器工作运行不佳 中冷器流道中有污垢，冷却水流动阻力增加，使进气密度下降，进而使增压压力下降。当中冷器、出气口的压差大于26.7kPa时，应予以清洗。4）涡轮机积炭。机燃烧不良以及涡轮霍尔塞特涡轮增压器（Holset ）密封装置失效而漏油，在涡轮机的叶片上转轴与密封环等易以形成积碳，其后果是是辽阳干式变压器旋转阻力增加、转速下降、机启动困难和加速不良，严重时可使涡轮霍尔塞特涡轮增压器（Holset ）停止跳动，增压压力随之下降。5）压气机或机气缸的密封性能差，外支撑式涡轮霍尔塞特涡轮增压器（Holset ），当其压气机背面气封损坏或机气缸密封性能下降时，一方面因为燃气泄露时涡轮转速下降，另一方面因近期泄露使压气机流量减小，两者均能导致增压压力降低。排除的方法是更换压气机气封和对机进行保养，恢复气缸的密封性能。6）涡轮背压过高。压气机排气不畅，排力阻力增大，燃气在涡轮中膨胀受到一定的抑制，导致涡轮功率降低、霍尔塞特涡轮增压器（Holset ）转速下降、压气机增压压力降低。造成涡轮背压过高的原因可能是排气管变形或排气消声器阻塞等。应予以拆卸、清洁或更换。7）喷嘴环工作运行不良。喷嘴环因长期处于高温下工作运行，其叶片变形，喷嘴环截面面积加大，导致辽阳干式变压器的转速和增压压力下降。因此，应更换喷嘴环。8）霍尔塞特涡轮增压器（Holset ）旁通阀失灵。霍尔塞特涡轮增压器（Holset ）旁通阀（霍尔塞特涡轮增压器（Holset ）压力调节阀）中调节弹簧因温度过高而失效，放气阀因积炭而封闭不严等原因使旁通阀失灵，在较低的增压压力水就放掉了较多的燃气，只是增压压力降低。出现这种现象可对旁通阀进行检修。9）连接处漏气。霍尔塞特涡轮增压器（Holset ）与机连接处漏气，如进气道胶管破裂、松脱等，使增压压力下降，应予以排除。10）辽阳干式变压器运动卡滞。涡轮霍尔塞特涡轮增压器（Holset ）的轴承磨损，辽阳干式变压器叶轮碰擦壳体，或有杂物阻滞，使增压压力随辽阳干式变压器速度的下降而降低。应予以更换轴承。
