Seal failure reason analysis
Still need to supplement the following for the sealing surface wear trace, check the wear trace, can help analysis of failure.
1. Wear wider: show that machine pump there had been a terrible wrong.
Its reason is bearing damage;Shaft vibration or shaft deformation;Shaft bending;Pump cavitation vibration;In the coupling of;The pipe serious deformation;Seal static ring tilt.
2. Mark the narrowing: grinding marks than two sealing surface minimum width narrow, this shows that overpressure sealing, pressure or temperature deformation of the sealing surface.
3. No grinding marks:
Sealing surface is not adhesive.Check whether spring compensation institution such as sliding or hampered.
4. No grinding crack but there are bright spots.
Sealing surface buckling will appear bright spot without grinding crack.Pressure is too high, gland screw is not tied to turn good or not good, or pump rough surface can form a bright spot.When two screw tied gland is used, its rigidity is not enough, the deformation is also one of the reasons that form the bright spot.
The emergence of this kind of symptom description: seal may leak a drive.
