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
resistances 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 nozzle capacity
of 2,5 kg/h. Max. permissible pressure
at the suction and pressure side is 2,0
bar.
Purging
On 1-pipe systems it is necessary to
purge the pump. On 2-pipe systems
purging is automatic through the
return line.
