i have 2 vacs ofcourse but one of them today sounded like metal grinding when on found out which one it is and that metal fan is wobberly can it be fixed or does it mean new vac
-
Sounds like the bottom fans fouling the metal case, a wobbly top fan is not much of an issue. ashby's do a curved
tool for taping the case open so the fans stop scrapping the 'lid' as it were.
hope this helps
-
is it safer just to get another vac dont want the thing jaming and blowing up etc

Hi Andy
Had that problem last week with my Prochem Steempro mate.
Have you tightened the 3 nuts down resent if you have you may have squash the bottom part on to the blades like what Paul said.
Mine was the motor had started to seize up.
Ended up buying 2 new motors just in case the other one went :'(
Hope you have some luck soon mate ;)

i feel worried maybe just easyier getting new vac but on these machines is one a slave and one a master ??
-
Hi Andy
Are the vac motors old ?
It might be best to buy a new motor
Mine were getting old so just replaced both
John Martin is the best person on this topic..He has help me out in the past.

i dont know how old the vacs are but i recently changed the bushes on them and plenty of lifting power in them untill the horrible noise started on one of the vacs

The mounting screws need to be tightened evenly.
If the screws are tightened to one side or over tightened it will knock
the fans/spindle off balance or out of true causing what you describe.
Undo the screws and run the motor....if it still sounds the same then it's f....d! and will need replacing.
When you install a new vac, ensure the spacers are ''exactly the same length'' or that the washers make up for any discrepancy in spacer length. And then only just nip up....don't over tighten.
In other words, if these motors are subject to over tightening to one side of the body, they will run out of true causing bearing failure.

blimey hope i dont tit this up

Although the advice above is spot-on concerning over-tightening - which might cause the fan "stages" inside the motor to foul.... I suspect you mean the cooling vanes which are on the back of the motor? This is exposed when you take off the black plastic casing
The way these are designed is very crude - they are simply forced on to the motor spindle, relying on friction to keep them in place. I have had motors where this has come loose so it no longer turns true. You need to use something like a small bit of metal tube and CAREFULLY hammer it back on to the spindle. 2 problems, firstly it is a b***rd to get it true again, and secondly if you force it on too far it will foul the casing when it is re-fitted. But with a little bit of jigging around you can sort it, unless you've forced the hole open too far.

i think your right jim i was thinking maybe silly idea but could it be solderd but then it made me think the soulder would melt as they get hot

thank you richard
-
Thats ok ;)
-
The operating temperature at that point couldn't melt solder, nowhere near enough heat but lead solder is going to be the wrong sort of metallurgy - it wouldn't bond I don't think. I can't remember whether those vanes are anodised steel or aluminium but it may be possible to spot weld, although you'd need to make sure it was running true and I don't know what effect the heat from welding would have on the rest of the motor, as the heat would carry along the motor spindle.
-
It's also possible that one of the vanes has been
knocked and is sitting proud of the others, this is common
too, if so just gently bend it back.
If the motors are over tightened then the first stage cowling
(furthest from motor) can be pushed down so thet the fan catches on the
cowling.
Carefully tapping the flange with a SMALL hammer away from the motor
all the way around, will ease the interference.
-
Super glues adequate to keep top cooling fans in place.

thank christ ive fixed it for the time being hope it last until xas then il buy it a present lol
-
Andy, when you decide to replace vac upgrade both to 1500wt 3 stage, well worth it.
Be careful getting vacs off ebay just stick to that seller mentioned. Most of us have been
shafted by cheap copies :o
If you need help let me know.
-
Nice one Andy ;)
I`am crossing my fingers for you mate
Richard
-
thank you everyone and i didnt know you could have 2 3 stages
-
Hi Andy
Do you have 2 motors in your ninji mate if you do you should have 2 3 stage vacs in it.
not to sure what the watts are but as Paul said upgrade to the new 1500 watt motors.
I was upgrading to this but phoned Prochem and they advise me to stick with the 1200 watt motors because its all to do with the tank.
Richard
-
ok thank you richard il call ashbys in morning just random question when a hoover says 2200 watts is that the power of its vac ??? surely not because thing would jump about at that speed of motor
-
Not sure on this but John Martin can explain more.
Check the new Enforcer on the Ashbys website and see the vac types on there they have a standard vac & a h/duty vac..

Richard
:) I am more an expert on googling than a dedicated motor specialist ...
There are some powerfull dry vacuum motors ... like this one
http://gallery.domel.si/products/files/496-3-457.pdf
but they are intended for dry filtered aspiration , most are one stage so don't have huge waterlift but good airflow .. and perhaps in the case above , powerfull but not as efficient per watt as the tangential design .
-
Cheers John ;) You are good on explaining
Richard
-
...and don't forget disguise ;)
-
Andy, You have two stage vacs ie two sets of fans on each vac., 3 stage being 3 sets, just check with ashbys they fit in the depth of the machine and the mounting holes line up.
