Learning diesel engine installation and connection will help to operate a diesel engine better and prolong the engine service's life. In this article, we will introduce China Shangchai G Series engine installation and connection.
3.1 Engine
Installation
There are
four engine installation supports on the both sides of the gear housing and
flywheel housing.
There are
lifting rings and plates on the engine, strong enough to bear the engine
weight. Chain pulley or other facilities can be used when lifting the engine.
However, attention should be paid to avoid thin parts or instrument parts of
the engine being pressed by stressed chains, causing damage to them. Keep the
lifting rings and plates from bearing bent moment and keep smooth handling when
lifting to remain the engine in horizontal position. The engine should be
placed on a special base or stable block to prevent the oil sump from directly
bearing the engine weight.
3.2 Engine
Connection
3.2.1 Intake
pipe extended
Caution: The
cross section of an air inlet pipe taken as extended part must be large enough.
To avoid big air inlet resistance, a pipe with inner diameter of 100 mm and
without sharp angles or over length is recommended for the pipes before and
after the intercooler. Air intake pipes must be well sealed or else early
engine wear will happen.
3.2.2
Coolant pipe extended .
The G series
V type diesel engine has a close loop cooling system, so there is no need to
have water pool or water tank. The recommended inner diameter of water pump
inlet is 61 mm and that of thermostat outlet pipe 54 mm.
3.2.3 Fuel
line extended
The fuel
inlet from and the fuel rectum to the fuel tank are showed in the figure below.
The capacity
of the fuel tank should be large enough to hold the fuel that can be used for
more than 8 hours. The fuel tank should be such positioned that the lowest fuel
level of fuel supply is l meter higher than the center of the fuel transfer
pump. The inlet port of the fuel suction pipe should be more than 50 mm above
the bottom of fuel tank. It is better to add a strainer at the inlet port to
avoid sucking in sediments that can block of the pipeline, and to have a drain
valve at the bottom of the fuel tank for an easy cleaning. The fuel tank should
be away from the heat source (such as exhaust manifold or exhaust pipes) and
electrical equipment.
3.2.4 Engine
power output
Engine power
output for driving the equipment is taken from flywheel. When using coupling to
connect the equipment, the center-line of the equipment should be in alignment
with the centerline of the crankshaft. If using an elastic coupling, the
misalignment shall not be greater than Φ0.30mm. If using a rigid coupling, the
misalignment shall not be greater than Φ0.10mm.
Caution: The
engine should not be started with load. So there should be a kind of clutch
device between the engine and driven equipment.
A certain
power can be taken from the front crankshaft of the engine. But the output
power for transverse driving with a belt directly on the front crankshaft
pulley should not exceed 11 kW.
It is
forbidden to directly install a pulley on the flywheel to drive equipment
transversely by belt because such operation can easily damage the crankshaft
and main bearings. If it is required to have a transverse driving, use an
engine or an additional device that is suitable for transverse driving. Do not
let the crankshaft and main bearings sustain transverse forces directly.
