What.

I agree just imagine having to stuff around with old oily stuff all day.
If you need an ex panel beater who spends 3 out of 4 weekends in Ballarat as an apprentice very good at using a broom for intended purpose pm me.

Hi Dean and Simplicity,
Even I have to agree it is the best job I've had in my entire working life.
Pretty tough to cope with this sort of work (and get paid) .
Today I fitted the other piston rod and set the valves before packing the glands.
Setting the valves on this type of pump is dead easy.
Make sure the piston is in the middle of its stroke and the valves are sitting centrally over the steam ports and the rock shaft levers are hanging vertically down.
Lock it all up and it's (normally) good to go.
After packing the steam end glands I couldn't help my self and went and got the air compressor.
The air compressor can be carried in one hand, including the receiver et al.
I am pleased to say that the pump will do at least 2 strokes (before it drained the air receiver).
It's going to the boiler house for testing where I'll use the 800CFM Ingersol Rand air compressor to make sure everything is going to be ok.
Fingers crossed.

Phil

Hi Phil, ive been watching your latest work pretty much since the start of my holidays and enjoying your latest work. How dare you get paid to have so much fun!!!

Thanks fof the pics and the descriptions.

I think this may have something to do with why Phil enjoys his work so much, look at the size of those sausage rolls they make there.

Do you think gets paid in ssusage rolls?

Thanks Simon,
I thought long and hard about posting again with all these 'social media' policies etc. but what the hell, this is more about engineering with a like minded group of people than deliberately offending others (well I hope it is ).
The next job coming up is a ripper. It's a Mumford wall pump that stands about 5foot (1.524m )tall

Hi Ray,
those sausage rolls are officially the best in Australia. They are now the current titleholders and I haven't even tried one yet.

First thing this morning I transported the pump and placed it on its plinth in readiness for some air.
I decided on using the Thompson Foundry air compressor run by that new fangled electricity stuff rather than the Ingersol
Well, the pump ran ok, good enough to hook it up to steam and water.
This involved hooking up the drain cocks and packing the valve rod glands and the water end glands of the piston rods.
I then searched for the water supply and delivery piping, dusted it off and reconnected them to their appropriate flanges etc.
I warmed the engine through with some steam and off it went, smooth as silk but with a metal to metal noise at one end of its stroke. A small valve adjustment alleviated the noise a bit so maybe a bit more adjustment is required.
With the pump hooked up and pumping against a bit of pressure from the boilers it started to take over and easily filled both boilers without missing a beat.
I half hooked up the exhaust pipe but ran out of time and won't be back at work until Sunday when I'll have another crack at it.
I am uploading some footage but I have a message telling me it is taking longer than usual. Really Sherlock, it has been 45 minutes now and it still says 0% uploaded.
I just may have been able to work that out myself .
Anyways, if and when that happens I will post a link.

Hi Phil,

So each D valve is moved by the opposite conrod(?). What happens if you stop the pump in the middle of the stroke?

Thanks for the pictures

Stuart

Hi Stuart,
That's impossible to do as they are never both meeting mid stroke. One piston rod will always be in advance of the other.
That is the whole concept of duplex double acting pumps. Great for boilers as they will always start no matter where they stop. Excellent in an emergency.

Phil

I sort of figured it was something like that but couldn't get my head around it and gave up waiting for the video
Thank you

Stuart

Where does the "used" steam go Phil? Is it condensed and added to the water being pumped or vented to atmosphere? I can see a line in but not something that looks like an out.

Hi Stuart,
lol, I gave up waiting for the video so I started again. Finally it uploaded

Hi Michael,
Some (probably most) pumps would exhaust through a feedwater heater to get a second use from it, or, like a condensing steam engine which has several uses in its favour, economical usage of steam and added power to the engine. These pumps are fairly small, comparatively speaking, so we won't gain much plus people (me included ) like to see and hear steam in exhaust. We do have a feedwater heater but when it was installed (before the time of the current group of blokes working here), it was piped up backwards and is seriously inefficient. We would get more return from installing an economiser in the boiler stack (chimney)

Here is the short video I took on the coolpix camera so I will apologise in advance for the shaky grainy footage.
