Fire Pump System Operation

I have read that. But it didnt explain about the duty pump and also the standby pump.

My point is, if you don't know what you are doing, DON'T DO ANYTHING!

IT IS IRRESPONSIBLE OF OTHERS TO PUT WHAT IS ESSENTAILLY A LOADED GUN INTO THHE HANDS OF A BLIND MAN!

I think he's just a student...

Perhaps, but if this is the way he completes an assignment, what will he do in the real world?

Searching and finding correct, authoritative answers, with adequate supporting data is something that must be learned early on.

Internet searches are, as you demonstrate every day, are not a black art.

Please dont mad at me..

My lecturer just tell me to find about fire pump, focus on Jockey, duty and standby pump. And I just doing my research based on that key point.

Maybe you can give me some idea regarding this

The same goes for negative critics.

Well,

Your total "contribution" of 6 posts means you have a way to go!

And in two of those posts, you are preaching to others about their lack of professionalism?

English Rose certainly didn't need an admonishment from the likes of you and neither do I.

Now, quit preaching and help the student do their homework!!!

"And in two of those posts, you are preaching to others about their lack of professionalism?" .......your words.

CR4 - The Engineer's Place for News and Discussion ^®

Where does it state CR4® is the place to go for your Engineering degree? It doesn't.

Lyn said it best in post #4, "IT IS IRRESPONSIBLE OF OTHERS TO PUT WHAT IS ESSENTIALLY A LOADED GUN INTO THE HANDS OF A BLIND MAN!"

Fire suppression system is life critical, lives depends on the Engineer getting it right the first time. An anonymous forum is not the place to acquire your engineering degree or skills.

I agree 100% with your and Lyn's intent here. Clueless, lazy people should not be allowed to design critical systems. I disagree that the design of a fire pump system is to save lives. A fire pump system attempts to prevent a bad situation from getting worse. Often lives will be saved in this process but life saving is not the primary goal. Respirators, defribulators, extraction harnesses and fire escapes saves lives. Putting out a fire protects property.

You right in the fact the pumps are for fire suppression. But if your on the 13th floor and the fire is on the 7th floor, it becomes life critical that the pumps operate properly and suppress the fire/ heat otherwise ..... you crapped out of luck

I got at least 30% of my engineering skills while staying at a Holiday Inn, or was that Howard Johnson's...I forget, since they did not issue me a certificate.

Please do elaborate your point: You mention negative critics. Is there another kind I am not aware of? Usually criticism is meant to point out flaws in a (1) design, (2) concept, (3) mathematical expression, or (4) constructed object.

If there were no negative (constructive) criticism, then no one would grow from their mistakes, receiving no feedback on weaknesses of what they are doing, they would progress from milding amusing to downright dangerous, to completely negligent contructions that result in injuries, maimings, and death.

I for one, thank God Almightly for engineers that can take criticism without taking it personally, and can dish it out as well as receive it. That, sir, is what the forum is for.

It is not the place for the little Johnnies of the world to come ask for the answer to their homework on a silver platter. We don't do that around here, we don't do floors, and we don't do windows, although we have criticized Windows (various versions) over and over again.

This might help....

<...standby pump...will start if the main duty pump cannot meet the demand...> Ahem, actually, that would make it an assist pump, and not a standby pump.

Ok, then what is it when the main duty pump is handling the situation without any further assistance? The non-assisting pump? Really? I think this pump is offline more of the time than online, therefore when it is ready to operate, but not operating it is the stand-by pump, because you are (or are not) standing by it.

What assignment does any pump need? ON or OFF are the only assignments the pump needs. Its not like one can give a pump the assignment to squirt water in room 375 above the wastebasket. The pipes, hoses, sprinklers and steering valves select and steer where the fire protecting or extinguishing fluid goes. The pump provides only pressure for the fluid.

The pump didn't get the assignment, the op did...

ROFLMAO! Wow. not a clue about the duty (main) pump, or the standby (backup) pump, and wants to think the jockey pump is there to provide flow during an event. How dangerous is that?

I worked on pressure tank system designed by my Australian boss Mr. Sam D Jovine. All electrical pumps. In this 1000 ltr pressure ventricle tank is used and small 1 HP pump keeps the pressure at 8 Bar against Air at top. When any sprinkler or jet opens, the pressure drop activates 30 HP pump.
