Faults for Diesel Generator Set Overload Operation
by Starlight Generator dieselgeneratortechOverload: operating
diesel generator beyond the rated capacity of the generator, in this
conditions, will causes an overload condition.
The
faults for diesel generator set overload operation:
1.Easy to damage air
cylinder of diesel engine;
2.Easy to cause
increasing heat load and mechanical load, which cylinder liners bear;
3.Supercharger of super
silent diesel generator set becomes red, the supercharger will be damaged for a
long-term high temperature;
4.Also easy to cause
pull cylinder and burn tile faults etc.
General reality, the
load of diesel generating set is 80% of the rated load, and the fuel
consumption is the smallest. If the load increases, the fuel consumption will
increase, and the fuel consumption of diesel generating set is proportional to
the load. But if when load less than 20%, not only the fuel consumption will
substantially raise, but also damage diesel generator set.
Therefore, if want to
reduce fuel consumption, we can let diesel generator run at load about 80% of
the rated load, long time load will increase fuel consumption, even damage
diesel generator. So should remember do not let diesel generator load for a long
time, otherwise, easy to cause faults.
If we ignore follow
problems, also will cause the genset overload, such as follows:
1. When purchase 100kw
generator set, buy 100kw standby power genset directly, long-term overload
operation will damage the diesel genset;
2. Poor heat
dissipation. Because the fan of the engine can not blow away the heat of the
water tank, so that making the water temperature rise. As a result, the
temperature of lubricating oil also rises, which resulting in insufficient oil
pressure and poor lubrication. Damage of moving parts, such as pulling
cylinder, piston and bearing bush, will affect the normal operation of engine;
3. Maintenance issues.
Failure to maintain on time results in dirty oil, reduced viscosity and blocked
filter, which resulting in insufficient lubrication, and damage of moving parts
lead to greater failure of the diesel generator set. Because of the quality
problems of diesel oil, the diesel filter will be blocked, the fuel supply will
not be smooth, and the genset will not have enough load. We should do the first
maintenance when the genset first operate 50 hours, after every 200 hours to
replace oil, oil filters, diesel filters. Air filters are regularly checked for
ambient dust. Replace immediately if there is a problem;
4.Personnel care
problem. No matter how good a machine or equipment is, if the responsible
person does not take care of it, the machine will not last long. It is also
very important to check all the machine's startup, check regularly during
operation, and make a good record of checking.
Overload operation is
very damaged to diesel generator set, because long-term overload operation will
accelerate the damage of parts, and very easy to cause faults.
