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 filter.
The sum of these individual resistances
is so insignificant 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
10,0 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.
With an underlying tank a 1-pipe-
system is not recommended
