Basic pump operation..what is your routine?
I'm a little ashamed to say this, but I have been in the biz for 10 years + and never actually run a pump on a scene. I have done it a few times in training and just messing around with the trucks, but never on a live scene. I want to better understand the basics of this so that if I ever am caught in a situation where I need to run it I will be able to do it. I think I have it mostly figured out, but I want to be sure so please correct me if I am wrong.
1. truck - air brakes on, in neutral, engage pump to half way position. let sit for a few seconds and then go all the way to fully engaged. put truck back in drive.
2. panel - if truck is not hooked up to a hydrant, engage tank to pump lever. figure out which line has been pulled, and open that valve (slowly). run throttle up to whatever psi is needed for a given line pulled.
3. Be sure relief valve is set, (usually slightly higher than psi of line or lines)?
4. If truck will be sitting for any period of time with pump engaged, open up a valve (or crack it) so that water can circulate through the pump and keep it cool.
Now, what I am not clear on is what needs to be done when I get a water supply. Do I shut the tank to pump valve off? If I understand this correctly, I need to be sure my tank is full before I kill that valve, just in case I lose my water supply for any reason...Just not clear on procedure to do so.
On the panel of one of our engines I was studying last night, we have two small guages in an area by theirself. One is water temp, and the other is oil temp. Is the water temp guage here for the engine's coolant temp, or is it talking about the temp of the water running in and around the pump??
Please feel free to post up your routine :)
