Description
Is the fuel pump part of the engine?
The engine driven fuel pump is part of the Excavator fuel system, one of the most important elements of the fuel system, like to any other internal combustion engine equipped vehicle.
What is the pressure of a fuel pump?
The
capability
of
the
high
pressure
gear
stage
of
the
pump
in
pressure
is
850
to
900
psi
(pounds
per
square
inches),
and
in
volume
displacement
50
to
60
U.
S.
Gallons,
or
13.000
litters
per
hour
at
maximum
nominal
operating
speed
of
the
pump
at
6250
rpm
for
this
pump,
and
when
the
engine
operates
to
take
off
power.
How a mechanical pump works?
A
mechanical
fuel
pump
is
driven
by
the
camshaft
,
or
by
a
special
shaft
driven
by
the
crankshaft
.
As
the
shaft
turns,
a
cam
passes
under
a
pivoted
lever
and
forces
it
up
at
one
end.
The other end of the lever, which is linked loosely to a rubber diaphragm forming the floor of a chamber in the pump, goes down and pulls the diaphragm with it.
When the lever pulls the diaphragm down, it creates suction that draws fuel along the fuel pipe into the pump through a one-way valve .
As the revolving cam turns further, so that it no longer presses on the lever, the lever is moved back by a return spring , relaxing its pull on the diaphragm.
The loosely linked lever does not push the diaphragm up, but there is a return spring that pushes against it.
The diaphragm can move up only by expelling petrol from the chamber. The petrol cannot go back through the first one-way valve, so it goes out through another one leading to the carburettor.
The carburettor admits petrol only as it needs it, through the needle valve in its float chamber.
