Thermia Matningsystem dead (Skruv)

[Gäst]

Hi all,

since yesterday afternoon, my thermia matningssystem is dead

After 800 kg of transported pellets the screw looks like this:



The screw was all in all 12m long

4m in the pellets storage + 1x 45° bow + 1m + 1x45° bow + 5m

I just ordered the spare parts and build a new matning with two motors and a box to handle over the pellets between...

Hej

Hur många och hur stora är hålen på skruven i förrådet?
Hur högt med pellets har du i förrådet?
Har du något centrumrör för skruven i förrådet?

Jag har 6 hål som är 6x6cm på skruven med centrumrör som är 6meter samt en planka ovanför som förhoppningsvis avlastar lite och som man kan gå på när det är tomt.

Hi,

the pellet storage is about 2 m filled. there are 3 inlets to the tube.
it is installed exactly the way thermia describes in it´s booklet

there is of course a centerpipe (made of copper) inside the pellet storage.

my dealer has a book which says: when this happens - screw too long


I have put some pics up here:



the green line is a bow, going directly to the pellets storage - the red line is the way to the pannrum

the motor was in the pannrum before- now i use it for the first part of my new matningsystem. below the motor i have planned to make a box made of wood, where the next skruv goes into and brings the pellets to the pannrum


the red points was another 45° bow

Strange..!

Thermia says that 24 Meters is the maximum of the Skrew.

On my skrew i have tow 45° & one 90°..

How can thay say that you are using to long skrew.. ?

800Kg has my skrew transported so far.. any time now?

hope not....

In think they mean that the screw i too long if you corelate it to the length of the tube.

no fear patrik...

i have heard strange sounds for a couple of days. a sound like the screw pulls and tears. every sound ended with a "tock".

if you hear nothing - no problem ( that´s what my dealer said).

The skrew engine must be verry power full. to make the skrew look like that..

/still going strong..

Today the first 24h test of my new matningsystem ended positely!

Now i have 2 skruv and 2 motors (större modell)

No.1 brings out the pellets of the storage
No2 brings them into the pannhus

The pellets fall out from skruv 1 directly into skruv 2.
There is only a plastic-bin around.
Because the 2 motors run exactly at the same speed, there is no problem with too much or to less pellets.

see here motor1+ from storage and below motor2 near the pannrum
PS: The bottom of pic1 is just full of pellets from trying around. The storage is directly at the lift side.
