Surface Cleaner Arm, NOZZLE TILT

[810F250]

I was looking at my mosmatic surface cleaner 3 arm spare part# 82.943 (for a 30" SC), and was wondering what was the angle of tilt on these welded mosmatic arms .

I have heard that some of the steel eagle (and mosmatic "s" style see link above) arms have an adjustable female nozzle port (so you can adjust the angle of tilt, hence increasing/decreasing the rotating speed and cleaning impact.

I was wondering what are the manufacturers set angle for different makes of Surface cleaners;

anyone know/measured what some of the arm angles are on the name brand Surface cleaners;

Landa
Steel eagle,
Mosmatic,
Whisper Wash,
Whirl-a-way.

I had a mill work protractor in the garage and the mosmatic non-adjustable arm 82.943 angle measured about 15 degrees. This angle does not seem to impart much of the fluid energy toward rotation.

Sounds like a good question for Mark.

I run Whisper Wash but know nothing about the angles of the tips or how they are set on the arms.

If there is a tip that allows you to adjust.....I'd be interested in hearing about them but wonder what examples one could post as to why you would want to decrease the speed of the arm??

If you decrease the speed of the arm then that would mean you would have to walk slower so you do not end up with "tiger strips"....am I correct on this guys and gals??

The Tips need to be tilted just a hair to get them to spin. That was part of my question quiz a few weeks ago. Some bars the elbows are welded on where the bar and the elbow are now one piece. I think that is what Nigel is asking as to what degree those elbows are tilted. At 0 degrees the tips are facing straight down and the bar won't spin(that was the answer to my problem in that quiz) If the elbow is a screw on which some of my surface machines are you can adjust that tilt angle. To get the tips to spin the fastest then you would most likely turn that elbow to a 90 degree tilt angle from the ground. That means the tips would be facing parallel to the ground. Yes the bars would be spining the fastest but the water would be not hitting the ground so there is no point to that. There is a degree that the elbows should be tilted at and its very small. My guess its no more then 10 degrees tilt away from the ground. On a bar with two tips these elbows have to be set opposite tilt angles to each other so the bar will spin. If there set where the one bar has both elbows tilted the same direction then the tips are working against each other and the bar wont spin.

Mark probably knows what this tilt angle is for these elbows to be set so the tips have maximum cleaning capacity.

I have a picture I'll attach here from a 3 bar surface machine that I purchase last year at the Toms RT. I think the principle is the same in that each elbow tilt is set opposite from the elbow accross from it because the principle seems to be the same. On this Hydrotek surface machine the bar and elbows are set and welded so you don't have to worry about reseting it. The draw back is if the elbow wears out and you are not a welder you might have to get a new bar set-up where thats expensive compared to just changing out an elbow.

Long post but I hope I explain it some even thought it does seem to be a bit confusing until you grasp it and as I'm typing this I'm getting lost that I have to stop for a second and rethink this to stay on track.[pc]

All bars are set right at 15 degrees. If you adjust them to say 10 it slows the bar down and if you set at 20 it speeds the bar up but not enough water hitting the ground for cleaning. Either way you will have to go slower when you use the surface cleaner to get it clean. Leave it at 15 degrees and you can change the tips to find your best cleaning. The tips that companys recomend are 0, 15, and 25. With most being the 25 degree tip for most coverage and cleaning. When my guys complain it isnt working good the first thing I check is the angle of the tips as mine are adjustable. And they normaly hit something and knock them out of adjustment, turn them back and it works like it should again.

15 is what I use. Never tried the 0. Played around with the 20 but didn't like it...went back to 15's

Thanks for the responses guys. I figured that the manufacturers had it set for optimal cleaning and speed but on paper 15 deg looked small (on paper, 45deg would be half the fluid energy to the spinning and the other half to the cleaning)and wondered if it could be tweaked I could gain a little more arm speed, translating to faster forward speed. I would have compensated for the impact by increasing gpm, pressure or decreasing nozzle angle (maybe 0503, instead of the 1503 I use).

So you have an adjustable elbow on the end of you SC arms, what make of SC is it?

Am I beating a dead horse, lol

Mine is a older Hydro twister unit. I am in the prosess of up grading it right now, if my parts ever show up. Putting a new Mosmatic swivel on and have to put there arm on it aswell. There arm is welded Im told so I wont have to worry about adjusting it anymore. My other cleaner will remain the same for now, so if they bump it I will just readjust it again.

Thanks any pics?

I have run a 3 arm SC (Whirl-A-Way), it was either 18" or 20" with 8 gpm, and compared that to my mosmatic 30" 3 arm with the same pump, hoses and nozzle angles, it allows twice as fast or more forward speed. But nothing beats the motor driven I have seen from Crystal Cleaning Company LLC (Jim Gamble's) modified turbo twister.

Just about all of our surface machines usually have the 15 degree tips but we have gone as high as 40 degree tips on them when dealing with New and soft concrete if just a rinse down doesn't work.

As for the 0 degree tips on the surface machine I heard when you have a motorized unit like me and Jim Gamble have there used to really clean very strong concrete such as most parking garage concrete floors that are going to be re-sealed after completion. Personally we also have never used a 0 degree tip on a surface machine.

Now on a House wash thats another story(For rinsing purposes for siding high off the ground)
