我们平时使用真空泵的过程中,经常会遇到各种问题,那我们应该如何判断和处理呢? 

一、真空度不高 

  (1)密封圈漏气。解决方案:检查所有密封部位的密封情况,更换破损的密封圈; 

  (2)气镇阀垫圈损坏或未拧紧。解决方案:更换垫圈并拧紧气镇阀; 

  (3)排气阀片损坏,密封不好。解决方案:更换气阀片; 

  (4)真空泵中隔板压入时过盈量太大,造成真空泵腔变形而漏气。解决方案:修整真空泵腔或更换。  

  (5)由于真空泵的端面油密封不良造成漏气。解决方案:拆开端盖,检查是否有杂物或不平整,并进行清洗或修理。 

  (6)转字弹簧变形或折断及旋片动作不灵。解决方案:整修或更换弹簧变形,使转子积旋片配合良好; 

  (7) 进气口的过滤网被堵塞。解决方案:取下过滤网清洗干净,再装上去。 

  (8)因加工不良或磨损造成配合间隙过大。解决方案:检查真空泵腔、转子、旋片、端盖板之间的配合间隙,投规定的精度要求进行修复或更换。 

  (9)真空泵运转中摩擦发热。温升太高,使真空泵油变稀,密封性变差。解决方案:通冷却水或用电风扇降温,同时,检查有关部件配合间隙并按规定精度要求进行修理或更换。

二、真空泵温度太高 

  (1)被抽气体温度过高。解决方案:应让气体冷却后再进入真空泵内。 

  (2)吸入硬物导致真空泵体磨损。解决方案:应拆开真空泵除去硬物,对划伤部件进行修复或更换。 

  (3)真空泵冷却水流量不够。解决方案:应加大冷却水流量。 

  (4)装配不当,使转子轴心位移,造成单面磨损。解决方案:拆开检查并重新装配。
