The difference is where the damage occurs on the impeller.
If it’s too severe case, pitting damage impellers. Let it not be the case, but if that is the case then check where the pitting on the impeller has happened.
Moreover, I asked the operator to throttle the discharge valve, that reduced the flow, and the noise got quiet. If had been the case of recirculation or air entrainment this wouldn’t have happened, the noise getting quiet.
What will happen if you see pump cavitation as an underrated warrior?
A good engineer will never let you down, man!
A Pump is a Heart of any plant and of course, your Heart is the closest pump to you.
Imagine, if your Heart stops, what will happen to you? Now imagine, if a pump stops?
That is why a running pump always has a standby pump!
Moreover, if something goes wrong, or if taken for granted anything can happen.
For instance, if this was a running pump supplying a cooling water from the cooling tower to a reactor, specifically where an exothermic reaction is taking place. And if the pump had stopped for some reason, let say because of some blockage or plugged strainer, thereby causing cavitation and low pump output, by the time your interlocks work or control valve take actions, this could have become next runaway plant case.
3 Things you must know as a Graduate Chemical Engineer
As a Graduate Chemical Engineer:
Do you wonder what sort of knowledge the industry demands?
Do you wonder what skills you need before they think of hiring you?
As an engineer, one needs to possess certain skill sets, which belongs to your field, at least to differentiate from other professionals.
It’s difficult to point out which skills are necessary and which one to neglect.
Or
Which will gain the upper hand and which one will not be worth your time?
Since our field has a vast horizon, so to say, you will come across all sorts of variations and diversions under the roof of Chemical Engineer.
I’m trying to focus on one of the quintessential skills that you as a graduate chemical engineer must know.
It will be useful to have this skill set, no matter what profile cap you are wearing. I am not going to talk analytical skills, leadership skills, communication skills, creativity, etc.
This article is supposed to be a quick know-how guide post, to step right into the understanding of practical approach about starting your career, assuming that you hold accountability for the rest of the knowledge you have learned in your graduation years.
Engineers communicate via diagrams and documents.
One of the important document is P&ID.
