In
this article, Starlight mainly talks about installation and use of CCEC Cummins generator.
1.The
design of machine room
2.Ventilation
system
The
machine room should be well ventilated.
A.Closed
cooling mode of fan water radiator: Fan radiator units have been installed in a
complete set, users do not need to install additional cooling devices;
B.The
air inlet area of generator room is 1.0 to 1.5 times of the front area of the
radiator, and the air outlet area is 1.0 to 1.5 times of the front area of the
radiator. If the ventilator is equipped with shutters or grids, the area of the
air outlet should also be increased;
C.If
there is window shades on exhaust duct which to adjust indoor temperature, when
indoor temperature, when indoor temperature is higher than 16 ℃, should close window
shades to discharge all hot air outdoor.
3.Exhaust
system
A.The
back pressure of air exhaust can not over 76mm Hg (10kPa);
B.We
recommend the exhaust pipe diameter: N series: 130/150mm, K6 series: 150/200mm
and KV series: 200/250mm;
C.Exhaust
system components should not be due to their own weight, inertia, relative
movement between components;
D.Flexible
pipes should be installed between supercharger and muffler exhaust pipes to
cause excessive stress caused by thermal expansion to damage supercharger and
exhaust manifold;
E.Exhaust
system must prevent any water from entering diesel engine or supercharger;
F.Fire
prevention and heat insulation should be paid attention to when the temperature
of exhaust pipe is high.
4.Intake
system
A.Intake
resistance should be less than 6.4kPa( New filter element<3.8kPa);
B.When
intake resistance is over 6.4kPa, the air intake resistance indicator will turn
red. The air filter core should be replaced at this time;
C.The
genset is usually installed in the engine room. In order to ensure the air flow
in the machine room, a large enough vent is necessary;
D.Air
filter inlet temperature should not be higher than 38 ℃, otherwise the exhaust
temperature will rise, power will drop, and will cause faults.
5.Fuel
system
Intake
resistance should be less than 102mm Hg.
The
fuel tank shall not be less than or higher than 1.6m of the crankshaft axis.
The
auxiliary (float) tank should be added when the tank exceeds 1.6m of the
crankshaft axis.
We
recommend fuel pipe diameter (Cummins) as follows:
Oil
supply pipe diameter: N series: 13mm, K6 series: 16mm, KV series: 22mm.
Return
pipe diameter: N series: 10mm, K6 series: 13mm, KV series: 16mm.
Fuel
pipes should not be galvanized, otherwise they will be easily corroded.
6.Electrical
systems
The
circuit voltage drop should be small, and the loop resistance is less than
0.002 ohms.
Battery
capacity:
KV38/50－1800CCA(400Ah)
N855/K19－900CCA(200Ah)
Low
temperature batteries are used below 20 ℃,
but the charge and discharge performance of batteries below 0 ℃ is very poor. Battery
heating (< 58 ℃) is conducive
to charging and discharging.
7.Engine
lubricating oil requirements
A.Viscosity
conforms to SAE 15W40; Quality conforms to API CF4 or higher grade;
B.Change
engine oil and filters regularly(250h);
C.When
on the plateau, must use CF4 or above CF4 level oil. Because on the plateau,
the burning situation of engine fuel is bad, oil contamination is rapid, oil
life below CF4 level is less than 250 hours (usually shorter in plateau than in
plain);
D.If
has not changed engine oil over the changing oil period, the engine will not be
properly lubricated and aggravate wear and tear, even block up filters, then
cause faults. On the plateau, accord to temperature to choose 10W30 or 15W40.
We
do not recommend to use single viscosity engine oil:
It
will cause serious problems when SAE40 is used in the environment below + 10 ℃ in summer.
Hot
zone engine oil (SAE50) will cause serious problems when it is used in the
environment below + 20 C, and it is also used in the engine before overhaul in
the temperate zone.
Requirements
of engine coolant liquid:
According
to the requirements to use water filter or add DCA dry powder to prevent
corrosion, cavitation and scaling of cooling systems.
Check
pressure cover sealability of water tank and whether there is leakage on
cooling systems, ensure the boiling point of the coolant does not decrease and
the cooling system is normal.
Use
coolant which scale between glycol and water is 57: 43 or the
manufacturer-approved coolant that meet below 45 ℃.
Check
regularly DCA concentration and freezing point in coolant.
