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 commissioning
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 3,0 Gph. Max. permissible pressure
at the suction and pressure side is 2,0
bar. For two-pipe system Q
max
= 55l/h
pump capacity at 0 bar.
