Type
GKD3B diesel locomotive is a new type of economic and environmental
protection shunting and transfer locomotive which is provided for
all the users in and out of railway. Its wheel arrangement is Co-Co,
axle load is 23t or 25t and max. speed is 100km/h. The locomotive
is designed depending on RAMS demand (namely reliability, applicability,
maintenance, security)
In the locomotive is installed a type
12V240ZJ diesel engine rated at 2000kW in vehicle. There are electronic
injection and mechanical injection methods for users to choose.
When adopt the electronic injection, the diesel engine cancel
the velometer, the speed becomes more stable, and the inertia
speed can be adjusted from 400r/min to 350r/min, so finally reduce
the oil consumption with no-load service. The pressure charging
system adopt pulse pressure charging, so the diesel engine has
a good following performance. It is very useful to the shunting,
because most of shunting locomotives under low-load service can
achieve good economic efficiency and emission performance. The
main generator adopts brushless excitation, cancels the exciter
and rectifier, so the main generator become more advanced and
reliable.
The locomotive adopts the programmed
control and adds a logical control and color LCD screen display.
The microcomputer control is more perfect, compared with the shunting
locomotive made by our factory before, the content is more, the
range is wider, operation is more reliable.
The driver¡¯s cab is designed according
to standardization cab. 23t or 25t axle load are adopted for the
locomotive, which can be choosen according to user¡¯s requirements.
The successful development of the type
GKD3B diesel locomotive adds a new member to our works¡¯ locomotive
series. The excellence of the structural and performance in this
type of locomotive decide it to has the stronger competitive power
in the same type locomotive in our country, and has the widely
market foreground. Now it has already been taken to the users
and it¡¯s operation is very good.
