Seeking advice on the cooling water issue for the mechanical seal of a centrifugal pump
Thread Content
Our company has several circulating water pumps for wet acid removal, and the mechanical seals in these pumps often fail. Upon inspection, it was found that the flushing and cooling water for the mechanical seals flows from top to bottom; I believe it should flow from bottom to top instead, so as to ensure that there is always water in the mechanical seal chambers. If the water flow decreases or there is a blockage, the return water will flow back immediately, which could result in a lack of water in the chambers. I would like to ask whether there are any relevant provisions to regulate this aspect, and what do everyone think should be done regarding its takeover?
What is the form of sealing at the site? What is the flushing protocol? Communicate with the manufacturer regarding the flow rate and pressure of the seal flushing cooling water.
Cooling water enters from below and exits from above – that’s common sense.
Double-sealed, generally with material entering from the side and exiting from above
