Hi Frank,
I like some of your ideas! I have however decided to use the rotating shaft
method. You bring up some valid points that I think I can mitigate if not
completely remove.
I will probably use a double seal, to increase the odds if one seal is
damaged. I also will use very close tolerances so that even if both seals failed
the leak is a nuisance rather than a serious and immediate safety concern. More
importantly in my opinion, is the breakaway design I will be using. I have
always been concerned that in the event I hit something that would snap the
rotating shaft the water pressure would blow the remaining shaft inboard,
leaving a large opening to the outside with no way of stopping the flow. In my
case this shaft will have a shoulder outboard so that this cannot happen and a
weaker necked down area that would fail first.
I am trying to keep most of my systems manual for reliability
concerns.
Keep sending those great ideas. It's always good to share ideas and usually
shows other good options to choose from.
Please contact me directly at kocpnt@tds.net . I may be able
to see you in late January if you will be home. I will be at a trade show in Las
Vegas and I think I may be able to sneak away!
Best Regards,
Jim Kocourek
