1. In some supercharger models,
in order to further improve its low-temperature starting performance, an intake
air preheating device is also provided on the intake pipe of the diesel engine,
and should be used correctly when starting at a low temperature.
2. After the diesel engine is
started, it must be accelerated before the oil pressure rises, otherwise it may
cause the supercharger bearing to burn out; especially when the diesel engine
replaces the lubricating oil, cleans the supercharger, filters or replaces the
filter element and stops for more than one week. After starting, in the idle
state, loosen the oil inlet connector on the supercharger, tighten the oil
after it overflows, and then idle for a few minutes before loading.
3. The diesel engine should avoid
idling for a long time, otherwise it will easily cause the oil in the
supercharger to leak into the compressor and cause the exhaust pipe to spray
oil.
4. After the new diesel engine or
the supercharger is replaced, the inlet pipe joint on the supercharger must be
removed, and 50~60ml of oil should be added to prevent the supercharger bearing
from being burnt out due to lack of oil during start-up.
5. Before the diesel engine
stops, it must be idling for 2~3min. Under non-special circumstances, it is not
allowed to stop suddenly to prevent the supercharger from overheating and
causing the supercharger bearing to die.
6. Frequently, after using the
diesel engine to stop, monitor whether there is any rubbing sound between the
turbocharger impeller and the casing. If there is a rubbing sound, immediately
disassemble the supercharger and check whether the bearing clearance is normal.
7. The sealing of the inlet and
exhaust pipes of the supercharged diesel engine must be maintained, otherwise
the performance of the diesel engine will be affected. Always check whether the
tightening nut or bolt is loose, whether the hose clamp is clamped, and if
necessary, replace the gasket.
Precautions for the use of diesel
generators for supercharged diesel engines
The turbocharged diesel engine of
the diesel generator set has the characteristics of improving the power of the
unit, improving the specific power, improving the fuel economy, reducing the
exhaust emission and noise, and thus is well received by the users. So what are
the precautions in the use process?
1. Among the 135 basic diesel
engines, the supercharged diesel engine designed before 1989, due to the low
compression ratio, the starting performance is not satisfactory. In order to
improve the starting performance, the turbocharged diesel engine that has been
designed and improved since 1989 has taken measures to increase the compression
ratio. In some supercharged models, in order to further improve its low
temperature starting performance, an intake air preheating device is also
provided on the intake pipe of the diesel engine.
2. The diesel engine should avoid
idling for a long time, otherwise it will easily cause the supercharger oil to
leak into the compressor and cause the exhaust pipe to spray oil.
3. After the diesel engine is
started, it must be accelerated before the oil pressure rises, otherwise it may
cause the supercharger bearing to burn out; especially when the diesel engine
replaces the lubricating oil, cleans the supercharger, filters or replaces the
filter element and stops for more than one week. After starting, in the idling
state, loosen the oil inlet connector on the supercharger, tighten the oil
after it overflows, and then idle for a few minutes before loading.
4. After the new diesel engine or
the supercharger is replaced, the inlet pipe joint on the supercharger must be
removed and the oil of 50-60m should be filled to prevent the supercharger
bearing from being burnt due to lack of oil during starting.
5. Before the generator set
stops, it needs to idle for 2-3 minutes. Under non-special circumstances, it is
not allowed to stop suddenly to prevent the supercharger bearing from being
killed due to overheating of the supercharger.
6. The sealing of the inlet and
exhaust pipes of the supercharged diesel engine must be maintained, otherwise
the performance of the diesel engine will be affected. Always check the
tightening nut or bolt for looseness and the hose clamp is clamped. Replace the
gasket if necessary.
7. Frequently, after using the
diesel engine to stop, monitor whether there is any rubbing sound between the
turbocharger impeller and the casing. If there is a rubbing sound, immediately
disassemble the supercharger and check whether the bearing clearance is normal.
