Pump / Controller Callibration

[rcproperty]

6m requires MORE pressure as there is increased resistance to the pump. As mentioned before I had to increase my pressure cut off on my controller by one notch when I went over to 6mm from 8mm because the increase in resistance kept cutting the pump out.

we never have that, our 6mm uses less pressure than our 8mm.

our controller is on a lower setting on the 6mm to get same flow than the 8mm

I see what you mean. You have to reduce the speed of the pump. So if you have a Spring controller, your speed setting could be 60 with minibore but would need to be reduced to 50 with microbore for the same flow at the brush.

But you will have to up the calibration of the controller to achieve the same result.

So many windies get confused with the controller figures on the first screen level. Just because it is divided up into 100 segments and our pumps are 100 psi rated, they confuse this with pressure. It is just the flow they are increasing or decreasing. The pressure is the calibration setting - its controlled by the amperage the pump draws as the pressure increases.

I don't use any digital controller, I use ones that I built myself!!

6mm hose requires more pressure- it's physics and fact. Your home made controller is irrelevant. Length of hose also plays it's part, connectors, fittings etc etc all build an "overall" amount of resistance- this is why all our settings differ from system to system. The longer the hose and smaller the bore the higher the amount of pressure is required to push water through it- it's simple physics.:thumbsup:

I best get new pressure gauges then, they must be wrong!!!!

Then your pumps manual pressure switch is set to accommodate both pipe sizes at the flow you need without cycling. What you are doing is slowing the pump down and this reduces the pumping rate.

I think pressure and flow are often confused with each other.

Forget each other.....i'm confused with myself!!

The amount of pressure you use should be the minimum amount required to achieve water out of the brush head so the pump works at it's optimum and dead ends quickly any more pressure used than is required will draw air into the system you don't want that. Flow is merely the amount of water used.

I hope that post didn't come across wrong, it wasn't aimed at you or meant to look like I was trying to be clever./emoticons/wink.png

We need a video of this, as I am lost, I don't know how to calibrate, mine set up works n haven't got any problems. My thoughts are if you have water flow going through hose n you pinch the end, the water comes out end faster, hence 2mm jets/fan. My brain cogs are slowly kind of understand flow n pressure

I never forgot my test marks in a physics test 9 out of 50 n 13 out of 50. Always felt gutted on how rubbish I was at that subject, as it seems like a fun subject.

When a system is set up and balanced correctly, you will achieve what PolesApart describes above. I have no jubilee clips on my system, all barbs/hoses are held in place only by plastic cable ties. I also use Hozelock type fittings throughout and have no leaks- never needed to waterproof any of my vans. I've read so many posts over the years with people having connectors "pop off" due to excessive and unnecessary pressure, persistent leaks etc etc. It often surprises me at how many, even experienced wfp'ers do not understand how their pumps and controllers should work. When you do understand it, you also know what things affect these parameters and thus how to adjust accordingly to keep things sweet.

I also concur. A video of how to callibrate a system correctly would be extremly valuable to many on here myself included so if on of you lads could take the time that would be most appreciated.

I also have a bone dry vehicle it's a sign you're running a watertight efficient system operating at it's best, I use a combo of pro26 and JGs for connectors, when I had a trolley system I had big problems at first was running on too much pressure with wrong calibration, I learned a lot off winpro or whatever that name is?

you lot a mad !!! wear on pumps ??????/ wtf , there 70 quid just binned them when there shot who cares northing lasts forever

I don't think the 70 quid is an issue, nor wear on the pump. It's about getting your system balanced and set up correctly, my current pump is about 8 years old and never missed a beat.

 

[♠Winp®oClean♠]

it is missing a beat it will be missing many beats and if you knew how to do a flow test like me you would die when you see how weak your pump is that why we bin us at around 2years

This pump came with it's current controller. Both are 8 years old. Both have worked together in all that time the same today as they did on day one 8 years ago. I still use the same pressure and flow setting today as I did 8 years ago to achieve exactly the same flow rate today as per 8 years ago. The pump is as quiet now as it was when new, in fact- nothing has changed in these 8 years of daily use. Now noddy, if there's some mysterious phenomenon why your pumps only last 2 years then you might want to pay a little more attention to the content of this thread!/emoticons/biggrin.png

Auto calibration of a digital controller.

Set pole running as in normal working conditions. Press the arrow up and the horizontal arrow for a few seconds until 'cal' comes up.

Press arrow down until 'aut' comes up.

Press horizontal arrow (set). C99 will appear, don't touch anything, just leave running until a number appears. Press horizontal arrow (set). This is now automatically calibrated for your particular setting. Off to the pub now

On Variastream digi (from memory) as it's in the shed press both the + and - together till the letters A-F appear and start flashing start at A then your turn the controller off, turn it back on and the flow rate should appear doesn't matter how high the flow is put it on about 5 upwards if you have water at the brush then pressure setting A is enough, that's still about 60 psi, we don't need pressure washers. I haven't seen other controllers but I presume it's more or less the same.

Interesting thread. Tomorrow i am cutting 30 meters off my 6mm hose and fitting on 50 meters of Gardiners reinforced pole hose.

With the way my roller system is setup it could make for a very nice setup.

Or explode.

I hope it's the former mate.
