RAB, (and others)

I took your advice and slowed her down. Then added some resistive loads.

The head started smoking and my appliance wires melted !

Just kidding

Here's the results of a quick test I did today. I'm not sure what can be concluded from this, but maybe one of you guys can help.

First at full speed:

NO LOAD:

Engine @ 1763 rpm

Head @ 1820 rpm (belt driven)

LOADED to 3.6kW/120VAC:

Engine @ 1705 rpm

Head @ 1760 rpm

That got her nice and hot.

(Governor did not hold the engine to the original speed, but that's another issue.)

Then a slower speed test:

LOADED: ( by plugging in two element heaters which draw 1300 watts each @120vac )

Engine @ 1284 rpm (the speed I intend to run when sheaves are changed)

Head @ 1332 rpm

When I turned on the loads (2.6kw total) she grunted a bit but handled the load nicely.

Here's where I need some help. I'm not sure what I accomplished by running the 1800 rpm head at 1332 with the resistive loads.

My estimated max. available power at this speed was between 2.6kW and 3kW.

Did the loads I added actually demand 2.6 kW of power from the head? and did they get it?

Does this test confirm that I can provide 2.6kW of power from the system once I change the sheaves to allow the engine to run at 1280 rpm while the head runs at 1800rpm ?

Thanks,

Veggie
