The fuel conveying pump takes charge of conveying the fuel to the diesel filter, then
to the fuel blowout pump. The fuel generates high pressure in the fuel blowout pump,
then spray into the combustion room to burn from fuel injector through high pressure
duct in the form of mist.
The fuel conveying pump is a single action piston oil pump. Installed at the external
side of the oil injection pump and driven by the eccentric gear on cam shaft of the fuel
injection pump.
The fuel injection pump has been calibrated by the manufactured. Do not dismantle
it without permission. If dismantling for repair and adjustment are required, please keep it
clean. Plunger piston, oil outlet and other couple part can not be exchanged.
Fully mechanical adjuster is employed. Rotation speed of the diesel increase
relatively; when the speed adjustment handle moves towards the direction for releasing
the spring, the oil supply amount reduces and rotation speed of the diesel reduces, too.
Do not change positions of the two screws for rotation speed limitation and limit screws
for maximum oil amount.
Stop working handle is installed on the casing of the adjuster, when the diesel needs
stopping, move the stopping working handle to realize emergency stop.
