Sirocco's new and improved 40" vacuum spinner

Jerry, what is the smallest angle nozzle that this SC can use without leaving an uncleaned area between the two spinner arms? Can zeros be used?

This is a good question Nigel.

I Looked into this some time ago when we thought of merging our Turbo Twisters together. Our solution was to have the first one up a little, ahead of the second one. The second one would over lap by a 1/2 of an inch at 0 degree nozzles.

The other way would be to have a timing belt ( Like a Harley Drive belt ) in play so that the wands are set as to not hit each other during the RPM's. We looked into this, but decided that if the belt was to slip or break, damage to the wands would occur. It would be allot safer just to offset the two Turbo Twisters instead.

Nigel,
the goal is not to use a zero degree nozzle spinning at super-sonic swivel-wear.
I believe a 25 degree nozzle, with a reasonable swivel speed will last laonger,
and allow you to clean faster, with a reasonable level of clean..
remember..
the customer only wants to pay you "70% of the money, for 80% of clean"

..It's a good thing you have someone like me to lead the engineering of
increased workspeed. Eh?


Jerry, is 25 deg the smallest angle nozzle that can be used in the unit, to obtain an overlap?

I wonder if any of the swabby guys broke their arm timing belts. John T?

How do you edit a post? Anyway

I just re-read this Jerry, I cant visualize how a zero deg nozzle would wear the swivel any faster than a wider angle nozzle (same orifice sizes), provided that the flow and pressure are the same at the swivel in each application.
 
Nigel,

You should have an Edit Post option, located near the bottom right corner of your post. Let us know if you do not have that option.

Great thread, really looking forward to the trip to El Cajon to see the monster machine in action.

"Perfection" is a goal rarely achieved

the swivel speed was referring to the nozzle-angle change.

and about the spray angle..
the closer you get to a 0 degree spray, the more likely you will have
perfemant abrasion lines in the swirl-marks in the concrete.
I look at it this way..

1) abrasions in the concrete is a liability problem.
wider is better to NOT have any of those complaints.
2) wider spray angle means you can go faster.
..as long as you have plenty of flow and pressure.
3) overlapping rotor paths means double-cleaning in a small ares..
..AKA..more lines left behind.

Now. Because most of my products were born at the servce counter..
I aim to have NO warranty issues..
perfection is my goal, on every level, as I want happy customers, and ALL the referrals.
..just like you, in yiour business.
Perfection is the goal, so here's the mix on the 40" surface cleaner..

I can NEVER suggest form even a moment a zero degree nozzle is a good idea.
If we have to go to 7gpm for every 20" of surface cleaner to "go fast".. so be it.
If we can "get AWAY WITH a 15 degree nozzle for better cleaning,
..on the jobs that justify a slower pace for better cleaning, .. so be it.
Changing to 25 degr. nozzles for the "production-style rinse-off".. fine.
Trying to convince all of you 4000psi minimum should be used on ALL large surface cleaners on outdoor concrete.. some will swallow it, others will whine about "why it won't work better" for quality-of-clean.

The cleaner you want to achieve, the more pressure and temperature you'd better be committed to.
..and I don't mean steam at 275+..
I mean 220 to 230 degrees is better than thiose wimpy 180 degree systems that those bean-counters ware selling.
I am building dual-heater dual-pump sysrtems for over 8gpm and getting GREAT results with multiple wands.. NO fussing.

I really want this 40" unit to be considered asperfect as perfect can be,
...all matters considered, like my 21" version.. it is WAY better in actual work-speed-efficiency than ANYthingelse out there.. because I tried THAT hard to deliver.
you should ALL own at least one, or you are wasting time and profitability..
you can run 2 of them with a 350cfm vacuum (16hp).
the 40" is only going to have 1 difficulty.. sucking up water on UNEVEN surfaces.
BUT.. you will be able to go real fast, on that mower,
relative to how big a system you back it up with..
I'm projecting for 100 linear feet per minute..
12 to 14gpm at 4000psi (or 4500psi for over 200 feet),
650cfm vac at 35hp (or 40hp for over 200 feet).
I HOPE it does that well with a 2"vac hose, but you might haveto go to 2 1/2"
..IF you are determined to go "that" fast.

Now don't be surprized.. I don't have convenient 12 to 14gpm "sitting around"
selling totally custom systems at very close to "mass-production" prices
does not pay very well..
If you guys will muster the faith to buy a deck,
put it in a mower, (and yes, I will talk you through that,)
and test it with "all you have"..
Jim, you have a monster.. hook it up, and together, we'll adjust it for all it can do.
the rest of you will achieve something less, BUT..
50 feet per minute is still 10,000 sq.ft. per hour, at 2cents sq. = $200. per hour
with just 1 man.
Belly up !
I've made it work, you tune it to your system..
it's done.

Jerry,

Still waiting for the updated dealer package, with the information
we discussed Monday. :confused:

Please e-mail today.:)

Yes I did. But consider this Nigel without counting the extremely large mowers out there I'm talking about 8' swaths mowers, That aside there is no reason to offset two surface machines as Jim is suggesting unless again your talking about a Giant Swath section of cleaning.

If 48",54" & 60" Mowers use the belt system then why can't a Powerwashing surface machine do the same?? They can. I did break the timing belt but that is so rare but if you know me then you will know that I do run into the strangest problems at times such as blowing out the clutch on the swabby when I was doing a parking garage I kept Engaging the clutch with the engine at full speed.(I use to race cars but that mentality goes out the window in Powerwashing).

But Just think about it for a second and Jim should to. If lawn mowers can do it then why can't Powerwashing surface machines do it with the belt system?? They can. But what Jerry is selling here IMHO is revolutionary and cost condusive to most powerwashers. Unless they ever have a reason to mass produce a swabby type machine everything about that machine is expensive because the Powerwashing parts to it such as the bars etc is custom designed just like Jerry's is here.

I like Jerry Reasoning here and for most it makes sense. If I get back in the money I might buy one of his machines to use along with the others that I have.....But right now I'm running a skeleton set-up and using what I have until.....I get back in the money:)

call Mark.. He has the prices.

thanks for all the interest.
..and encouragement.

I've put lots of thought, sweat, money and time into this system.
Also, I believe I've "nailed" the price-point too..
the prices are set to inspire you to focus on growing your cleaning business,
..or at least giving you more time to enjoy your income.

It's time to call Mark.. He has the prices.
