In actual production, how long does it take for leakage to occur due to pump cavitation or air entrainment? (HAZOP)
Thread Content
During HAZOP analysis, it is common to encounter a low liquid level in the tank ahead of the pump; without protection, this can lead to cavitation in the pump or operation without any liquid present. I would like to ask the experts: in actual production, for ordinary centrifugal pumps, if cavitation occurs, how long does it take before seal failure leads to leakage? What happens with gas application? What about shielded pumps and magnetic drive pumps?
It is recommended to first understand the principles, phenomena, and hazards of \"gas binding\" and \"cavitation\", and then the answer will become clear. For reference.
