Operation
MB-DLE 407 gas train
AS47D fuel oil pump
Operation
When the magnetic coils are switched
on, valves
Y12
and
Y13
open. The valve
seats are protected against impurities by
a fine screen fitted upstream. The
integrated pressure regulator regulates
the desired outlet pressure.
The adjustment values required for:
- the gas pressure switch
- the gas pressure regulator
- the starting gas pressure
(MB-DLE407)
may be adjusted using the screw. The
inlet and outlet pressure can be
measured at the pressure taps.

The fuel oil pump used is a self-priming
gear pump, which must be connected as
a two-line pump via a bleed filter. There
is an intake filter and a fuel oil pressure
regulator integrated in the pump. Before
commissioning, install pressure gauges
for the pressure (
4
) and vacuum (
5
)
measurements.
