Suction line tables
The suction line tables consist
of theoretically calculated values
where the pipe dimensions and oil
velocity have been matched so that
turbulences will not occur. Such
turbulences will result in increased
pressure losses and in acoustic
noise in the pipe system. In addition
to drawn copper piping a pipe system
usually comprises 4 elbows, a non-
return valve, a cut-off valve and an
external oil ilter.
The sum of these individual resist-
ances is so insigniicant that they
can be disregarded. The tables do
not include any lengths exceeding
100 m as experience shows that
longer lengths are not needed.
The tables apply to a standard fuel
oil of normal commercial quality
according to current standards. On
commis sioning with an empty tube
system the oil pump should not be
run without oil for more than 5 min.
(a condition is that the pump is being
lubricated during operation).
The tables state the total suction line
length in metres at a viscosity of
6,0 mm

Purging
On 1-pipe systems it is necessary to
purge the pump. On 2-pipe systems
purging is automatic through the return
line.
