Hello,

 I made the drawings for about five months. The second drawings for casting of gray cast iron I gave for the production of wooden models. Wooden models I put into another casting company. All preparation to have the first test castings was almost one year. So, I gave myself the perfect gift for Christmas.

Great looking castings and great start to the machining.

It must be so satisfying to be working at last on the castings you have designed yourself and had poured.

Looking forward to seeing the way you build this model to your usual high standard.

Gray cast iron works well, total preparation including wooden models, castings, drawings, was one year ...

As always Paval, more than suitably impressed with your valve work. You appear to have in this build selected 90 degree isolation valves for all or both applications

Are these simply 90 degree rotation tapered plug valves?.......apart from using the same saddle cross slide angle setup for both valve bodies and plugs, is there any lapping, or just grease with metal on metal  for sealing?

Without giving any secrets away  :happyreader:  ...do you select say a harder [aluminium bronze] for the valve body then brass for the plug?

Always good to see..... :Doh:

Lastly, what is this?....... a glass cylinder with a free floating Teflon piston with an energised o-ring in an exhaust line?  :facepalm:

Derek

Hi, I'll try to answer everything. Sorry for my English. Two glass cylinders - 1 is a thermometer up to 100 C, the other is a float gauge. The steam outlet is connected to a water condensate cooler. I make taps (valves) on a lathe where I set 2.5 degrees. The taps must be applied with abrasive paste.

Beautiful work as always, Pavel.  The whole plant is most impressive.

I am another always particularly  impressed by your valves, they look fabulous

Thanks also for the detail of the sight glass.  That method solves some of the alignment problems as well as structural strength of the more common two part designs.

Post by: crueby on October 03, 2021, 03:08:20 AM
Hi Pavel,


The injectors have a small opening in the nozzle, possibly it got clogged. If it cannot get enough flow through the nozzle to draw water through the side opening, it won't work. Or the check valve at the opening to the boiler is jammed shut. Do you use distilled water? Minerals in the water can accumulate and clog the openings. Soaking the injector and valve in vinegar can clean them up


Chris

Title: Re: Buffalo steam engine model
Post by: Zephyrin on October 03, 2021, 08:24:30 AM
great work with this engine, very realistic.
with this tiny injector, most probably the temperature is to high to function properly; no condensation occurs, and the injection fails.
may be the injector is too close from the boiler, or heated by the copper pipes, or the water from the tank is too hot.

In short the Giffard injector functions as follows :
The velocity of the steam jet draws water from the tank by Venturi effect. The steam mixes to water and condenses, and the resulting heated water jet is accelerated in a converging nozzle.
The water jet then enters a diverging nozzle, which causes the jet to slow down and creates a pressure rise (which depends on the jet's speed and density; that is the water density now, not of the steam, which is where the genius of the process lies !), the water jet is then at a higher pressure easily above boiler pressure, and passes through an inlet valve and fills the boiler...
Title: Re: Buffalo steam engine model
Post by: rarach22 on October 03, 2021, 08:47:47 AM
thank you, it looks like hot water in the tank where the temperature was high. I have to build it differently ..... I have to build another non-return valve and use a hose to suck in cold water  Pavel :ThumbsUp:

Hi
looking at your piping the over flow goes back to the water tank that would sone heat up the water i usually have only a short aver flow pipe
it need to have e free passage to let that initial expansion of steam as it leaves the steam nozzle out it needs to go some were out the over flow this sudden expansion is when the steam condenses slowing down but still at high speed into the combining cone creating a low pressure so the water rushes in and is carried though the combining cone  it needs to be the right volume to be able to continue condense the steam  .as it flows trough the delivery cone it increases pressure to go into the boiler.if the water is to hot it does not condense the steam
and it will stop or not work if it worked to start with it cannot be much wrong.i have made new cones for some 3/8"injectors recently just made what i thought the old cones were badly damaged or missing they all worked and over the full range full boiler pressure down to 20 or 30 psi. when they have stopped working they were blocked with leaves from the feed water .
John.

Excellent, Pavel, very satisfying.

That little puff of steam and water out of the overflow as it starts is a positive sign that all is well.

Great to see the whole plant working.  Is that a fan being driven by the engine with the ducting to help draft?

Pavel...what are you adjusting on the shell of the generator to alter the generator output [voltage]? 

It is the positioning of an additional ferric magnet adding to the stator magnetic strength?, so to increase the load demand to overcome the additional stator EMF.........[maybe EMF is an incorrect term?....maybe just strength?]

When asking Google :happyreader: about magnetic strength, it  says.......'one tesla is equal to one weber per square metre'  :lolb:
