1.Primary technical
maintenance: 50-80 hours. (Added to the content of daily maintenance)
A. Replace and clean air
filter if necessary. The air filter is an unconspicuous but important part of
the whole diesel generator set. Once the air filter is too dirty, it may cause
serious mechanical accidents, especially in the environment and areas with poor
air quality. In order to avoid shortening the service life of diesel generator,
after shutdown, check the air filter in time and whether the air filter is
blockage and damage. If so, clean and replace it in time.
B. Check and replace the
fuel filter and water filter;
C. Check the tension of
the drive belt;
D. Add lubricating oil
to all oil injection nozzles and lubricating parts;
E. Replace cooling
water.
2.Secondary technical
maintenance: 250-300 hours. (Added to the contents of daily maintenance and
primary maintenance)
A. Clean the piston,
piston pin, cylinder sleeve, piston ring and connecting rod bearing of diesel
generator regularly, and check its wear situation;
B. Check whether the
inner and outer rings of the rolling main bearing are loose;
C. Remove the scale and
sediment in the water channel of the cooling water system;
D. Remove the carbon
deposit in the combustion chamber of the cylinder and the inlet and exhaust
pipe;
E. Check the matching
wear of valve, valve seat, push rod and rocker arm, and make grinding
adjustment;
F. Clean the carbon
deposit on the turbocharger rotor, check the wear situation of the bearing and
impeller, and repair them if necessary;
G. Check whether the
bolts of the coupling between the diesel generator and the diesel engine are
loose and slip. If there is problem, should replace in time.
3.There-level technical
maintenance: 500-1000 hours. (Added to the contents of daily maintenance,
primary maintenance and secondary maintenance)
A. Check and adjust fuel
injection lift angle;
B. Clean the fuel tank;
C. Clean the oil pan;
D. Check the atomization
of fuel injection nozzle.
Diesel engine is easy to
break down when diesel generator set runs for a long time, we must also pay
attention to the overall inspection of the diesel engine. If not found and
handled in time, the generator set may be damaged over time.
After the above
technical maintenance, it can basically help the use of 500kw Volvo diesel
generator, reduce the probability of failure, and extend the service life.
4.Medium
maintenance
After the diesel
generator set runs total 6000-8000 hours, we can carry out medium maintenance.
The specific maintenance contents are as follows:
A. Check the wear degree
of the valve and valve seat, and repair or replace if necessary;
B. Check the working
condition of PT pump and fuel injector, repair and adjust if necessary;
C. Check and adjust the
torque between connecting rod and every fastening screw;
D. Check and adjust the
valve clearance of diesel generator set;
E. Adjust the fuel
injector stroke;
F. Check and adjust the
tension of fan charger belt;
G. Clean the carbon deposit
in the intake branch pipe;
H. Clean intercooler
core;
I. Clean the whole oil
lubrication system of the diesel generator set;
J. Clean the oil sludge
and metal scrap of rocker arm chamber and oil pan;
K. Check the
easy-to-break parts of cylinder liner, piston, piston ring, intake and exhaust
valve, etc. crank and connecting rod mechanism, gas distribution mechanism,
lubrication system, cooling system. Replace if necessary;
L. Check the fuel supply
system of diesel generator set and adjust the oil nozzle of oil pump;
M. Repair and test the
electric ball of the generator, clean the grease and sediment, and lubricate
the electric ball bearing.
In order to prolong the
service life of 500kw Volvo diesel generator set, attention should be paid to
maintenance. Be sure to unload the load before shutdown, and do not shut down
with load. Try not to operate the generator set with high power for a long time
under the condition of poor environment, and check it regularly.
