Fuel pump as condensate pump - experiences

Post by dampfspieler »

Hi,

in a new project i want to use a DELCO fuel pump as condensate pump, like done at the plants of STUART Cygnet or Swan. Are there any experiences with that configuration?

Regards

I remember reading about these kind of installations in the 1990s in Steamboating.... there's some more recent discussion here if you have facebook:

That is an interesting idea. Also having a Cygnet engine and also thinking about condensing it might be something for me to adopt. There do seem to be lots of ACDelco pumps available on eBay at quite reasonable prices.

I look forward to seeing how you get on with the idea.

In this part of the world (Cymru) I am fighting with a new Raspberry Pi 5 which refuses to see the keyboard under the GUI but will happily work with it at OS level. I think the Raspberry Pi Connect system that allows one to 'control' the Pi from another computer is going to provide a fix. Next up is to install Python and get the two thermocouples for the mono-tube boiler sending me some figures. The untimate aim is to have the Pi control the electric feed pumps using the thermocouple data. Once I have sime progress I will post up some details. The whole story so far is to be found on [https://mono-tube.org.uk/index.php/tech ... ight-canoe]

Regards

Hello Peter,

yes it is. However, implementing the modifications is somewhat challenging, especially since it would likely be sensible to build a pump unit with all the necessary pumps (condensate, feed water, steam lubricant, circulating for the condenser), as can be seen in the pictures below.

Hello,

since only three images are allowed in one post, here's another picture showing the pump gearbox. The machine speed is reduced by half to ensure the pump valves operate reliably. Above 500 revolutions per minute, the pump valves require slightly more effort.
