Operation Manual of WEICHAI GENSET
Installation of the generator set
1. Size of machine room
In order to meet the requirements on
maintenance around the set, it is
suggested that the distance between the
machine room and any wall, cabinet or
control cabinet should be at least 1 m.
2. Intake and vent louvers
The effective ventilation area of intake
and vent louvers shall not be less than
50%, with good flow line and low air flow
resistance.
Bird/pest protection nets shall be
installed inside the louvers, but shall not
hinder cooling and air flow.
The vent louvers shall be connected to
the set radiator tank through a flexible
connection resistant to heat and oil.
3. Smoke exhaust system
In the layout of the machine room, the
smoke exhaust system is fixed by the
hangers fixed on the ceiling. If this
method is not applicable to the structure
of the building, the exhaust pipe needs
to be supported from the ground. The
exhaust pipe shall be at least 2.3 m from
the ground to ensure the safety of
people in the room and to prevent
sudden contact.
It is suggested that corrugated pipes
should be installed at the exhaust outlet
of the set and then connected with the
smoke exhaust silencer through a rigid
pipe.
In order to lower the temperature in
the machine room, the exhaust pipe
shall be wrapped with thermal insulation
materials with high density and high
insulation performance. If possible, the
silencers and exhaust pipes shall be
installed outside the machine room to
the greatest extent.
4. Cable system
The output cable from the set output
switch to the distribution box shall be of
flexible structure. It is suggested that the
flexible power output cable should be
laid on the rack in the cable duct of
recommended size and be separated
from the control cable.
The flexible single-core power cable that
enters any control cabinet must pass
through a nonmetallic sealing sleeve and
plate.
5. Switching screen
It is divided into wall-mounted type and
floor type.
Wall-mounted type: The screen below
600A can be mounted directly on the
wall of the cable trench;
Floor type: Certain space is required for
installation of the screen above 800A.
Certain space and operator access shall
be reserved around the switching screen.
6. Generator set
The length of the duct between the
radiator tank and the air duct shall not
be less than 300mm.
The air inlet shall be behind the motor
end of the generator set to obtain good
air circulation.
7. Door of machine room
The door of machine room shall be
opened outward so that the door can be
closed better during the operation of the
set, but a door button or handle for
evacuation must be provided in the
machine room to facilitate the rapid
evacuation from the machine room.
