Description and Purpose
Driven by the force of the engine exhaust.
Compresses intake air to a density up to four
times that of atmospheric pressure. This
greater amount of dense air allows more fuel to
be burned, thereby doubling the engine’s power
output. The turbocharger also reduces exhaust
emissions and exhaust noise.
Exhaust gases are expelled through the exhaust
manifold to the turbocharger. The gases are
then expelled by the turbocharger through the
muffler, exhaust pipes and rain cap. Engine
noise is reduced by passing exhaust through the
muffler. Rain is kept out by the rain cap.
Provides the interface between the diesel engine
and the water pump. The pump rotating assembly
contains the impeller shaft of the pump which is
supported by a single, self-lubricated,
permanently sealed, ball bearing. The impeller
shaft drives the impeller which causes the pump
to transfer water.
Tie down points are used to secure the pump
assembly to transportation vehicles. The sling
load points are hard points used for sling
operations.
Used to support and transport the pumping
assembly.
Encloses all V-belts to prevent foreign objects
from interfering with operation or personal
injury. Covers crankshaft, alternator, and
tension pulleys.
Maintains a supply of fresh air to each cylinder
so that air can be drawn into each cylinder on
the intake stroke. The turbocharger draws air
through a clean air filter and air intake pipe
assembly. The air supply is kept under pressure
by the turbocharger to provide additional power
from the engine.
Stores diesel fuel, used to power diesel engine
operation.
SECTION III. PRINCIPLES OF OPERATION
PUMPING ASSEMBLY OVERVIEW.
1.15.1 General.
The 600 GPM pumping assembly is a mobile system that transfers
potable water. It is trailer mounted and is towed by a vehicle for short distances.
When relocated, the 600 GPM pumping assembly is disconnected from the vehicle and
stabilized. When used as a source pump the pumping assembly is connected between
the water source and TWDS. When used as a booster pump, the pump disconnected to
hose assemblies. When the engine is started, the water flow through the pump is
controlled by gate valves. The following paragraphs provide a detailed functional
description of the 600 GPM Pumping Assembly.
