How does the mechanical seal flushing oil and isolation fluid flow?
Thread Content
What is the specific flow direction of the seal flushing oil and isolation fluid in mechanical pumps? Some of them also have channels for circulating water – what exactly is the flow path in those cases? I’d like to clarify this
The flushing oil is pumped from the outlet of the pump to the mechanical seal. If the mechanical seal does not leak, the isolation fluid does not flow; once there is a leak in the mechanical seal, the fluid will enter the isolation system, causing the level of the isolation fluid to rise as well as the pressure. The circulating water is used to cool it down
I understand all of what you’ve mentioned. I’d like to know how the flow takes place within a mechanical seal, or it would be helpful if you could provide an image to illustrate it more clearly
It’s hard to explain this in just a short time; when you have the chance to take it apart and look at it, it will become clear. A mechanical seal usually has two sealing surfaces that are perpendicular to the axis of rotation, which is why it can also be referred to as a \"radial face seal\". One of the sealing surface components is mounted on the pump cover, end cover, or pump body and remains stationary; the other is fixed to the shaft and rotates along with it. The stationary one is called the static ring assembly (in stationary mechanical seals, it is also referred to as the floating ring assembly), while the rotating one is called the dynamic ring (rotating ring) assembly
Okay, I’ll take a look at the actual item to confirm. Thank you for your patience in answering my questions
