Dimensionering van de buisleiding
De tabellen voor de twee- resp. éénpijpsinstallatie tonen
de maximaal mogelijke buisleidinglengte, afhankeljk van 3
factoren:
hoogteverschil tussen pomp en tank (H)
oliedebiet resp. pomptype
buisleidingdoormeter (DN)
Er werd in deze tabel rekening gehouden met de
gebruikelijke drukverliezen veroorzaakt door filter, voetklep,
buisboogstukken en olieslangen.
Voor de montage van de olieslangen in de toevoer- en
terugloop (tussen pomp en vaste buisinstallatie)
moeten de productgebonden installatietekeningen in
acht genomen worden.
Voor gasolie verwarming worden olieslangen volgens
DIN 4798, deel 1, drukklasse A, geleverd.
Technische gegevens:
Nominale druk _________________________ P
N
= 10 bar
Proefdruk _____________________________ P
P
= 15 bar
Bedrijfstemperatuur _____________________ T
B
= 7C
Na de montage moeten de leidingen (zonder oliefilter en
olieslang) een drukproef ondergaan. De controle gebeurt
met perslucht of stikstof, bij een min. druk van 5 bar. De
brander mag tijdens deze test niet aangesloten zijn.
