Unexpected Injector Failure Cause

Hi all, Hopefully the following may be of use to someone experiencing similar symptoms with their injectors…. I was testing some new injectors recently using the traction engine as a testbed. My plan was to install an injector, see if it would repeatedly pick up around 50psi and then raise boiler pr...

I'll hopefully be there with the traction engine either on the Saturday or the Sunday John.

Re: Boiler treatment

Hi Glenn, This subject comes up periodically. You may want to search on a thread titled "Water Treatment Targets and Method" which attempted to answer these same questions in a fashion that was applicable for anyone's situation. Marty's over-arching points about boiler washouts and storage are vital...

Re: Vacuum Ejector Drawing / Guidance

As an update, I ultimately used the cone configuration described by DAG Brown at the back of his injector book and this seems to work well. On air the ejector pulls to 18 inches Hg from 40psi upwards which is what I was aiming for. Fred - the cone configuration in your drawings are similar but not i...

Steam Fairgrounds and Onward

The attached video may be of interest to folks in the US, it's one example of the extent to which steam remains a mainstream pastime in the UK. For those unfamiliar, all of the fairground rides are steam-powered. The rides are powered either directly from a dedicated engine as in the case of the gal...

Re: Vacuum Ejector Drawing / Guidance

Many thanks Julian,
I'll try the ejector cone modifications as you suggest - it's great to hear that you have had good success after modifying the design.
Like you, I'd used an injector steam cone inlet reamer to make the ejector steam cone entry.
Best regards

Re: Vacuum Ejector Drawing / Guidance

Drawings received and printed - many thanks Fred. I'll make up one of each and see how they compare on air on the bench. I'd hoped for a bit more suck than the 17" I'm currently getting. Keith Wilson's original article suggested that the ejector would pull 20" at 40psi but it's quite possible that t...

Re: Vacuum Ejector Drawing / Guidance

Thanks Fred, the drawings would be much appreciated. I'll PM you with my Email if that's okay.
Do you recall what vacuum you've achieved with yours?
Best regards

Vacuum Ejector Drawing / Guidance

Hi there, Does anyone have a drawing or sketch of a vacuum ejector that they've built and found to be successful? I'm aiming for 20" Hg at 60psi. Testing mine on air this weekend, built to a Keith Wilson drawing from a 1980's Model Engineer, it pulls to 17" Hg at 80psi but only 8" at 60psi. The ejec...
