Hello rocketscientist!
Could you give that formula in "Finnish"!!!
I really don't get it. Maybe its your way to put it, but please advise me:
P = 6.566 X 10 and then what??
What is S.G.?
Thanx in advance
Hello!
I don't think that it goes just multiplying. When there is level enough in the tank that first impellers move the slurry, second and third impellers don't increase the power consumption a lot. I have at the moment 47 m3 slurry in the tank and there are two impellers in touch with...
Can somebody explain how to do this http://www.eng-tips.com/viewthread.cfm?qid=153109&page=8
I'm trying to do same kind of excel spreadsheet from process variables (temperature,flow,solids) and then get min, max and average values of data. Maybe charts too.
Values from process (Omron PLC and...
Simple question: what is the reason to use mechanical sealings or sealings what so ever, for example in centrifugal pumps?? What is its function??

Hello!
I changed 1450 rpm 4 kW motor to 2990 4 kW motor, but it took overcurrent all the time at the same flows (waterpump) so I had to change old motor back.
I guess that your boss is right.

Thank you TrevorP. We have quite a lot of experiences with these meters, but not in this kind of application. Nowadays throughtput is about 180.000 kg/h with DN80 meter, which is quite good. This info was from manufacturer, so I will ask written quarantee of it, otherwise we will return it.
We...
Hello all!
Has anybody long term experiences with mass flow meters? We are planning to measure slurry amount by using above meter and total counter instead of weighing to whole tank truck. I know that accuracy of such meters are up to 0.10 % which is enough, but how sure can I be with the...
We use Atrex high speed mixer in making pigment slurry up to 72 % solids. http://www.megatrex.com/.
Mixer was first designed to make concrete, but new applications are developed all the time.

We tried to use Discflo pump in our slurry plant. If the viscosity, solids, flow and pressure were the same all the time => no problemos, but if changes in some parameters => no can do.
So we said adios to Discflo after 8 hours testing.

We have used seals made of teflon and nylon. Nylon is much more cheaper. I'm not sure are talking about same system, our agitator is up in the tank roof and agitator shaft is in this seal at the bottom.
We just buy a nylon bar and turner will do the rest.

In Finnish paper industry people use more and more Vacon and ABB VFDs. If you go more than 30 kW power, the price difference is quite high.
At least in Finland, Allweiler is out of market 'cause the prices for spare parts almost double comparing Bredel and Wangen.
In Finland is saying: flow...
