What If the Diesel Generator Set Is Overheating?
by Starlight Generator dieselgeneratortechExcessive operation of
the the diesel engine will result in a decrease in the power of the diesel
engine, a deterioration in the acceleration performance, and an increase in the
wear of the moving parts. In severe cases, malignant failures such as pulling
the cylinder, sticking the cylinder, burning the tile and burning the piston
may occur, resulting in serious damage to the diesel engine.
What
should I do if the diesel generator set is partially overheated?
As the temperature rises
throughout the summer, it is easy to cause the diesel generator set to heat up.
We can judge whether the genset is running normally from the aspects of sound
and temperature. Let’s share the local overheat prevention and countermeasures
for diesel generator sets.
1. Regularly check the
contact condition of the electric brake blade static contact, and find that the
compression spring is loose or the single contact finger is not parallel with
other fingers and should be dealt with in time.
2. The generator outlet
and the neutral point lead connection part should be reliable. During the
operation of the generator set, the infrared imaging temperature measurement of
the split-phase cable, the static excitation device to the rotor slip ring
cable and the rotor slip ring of the excitation to the static excitation device
should be performed periodically.
3. In the commissioning
of new machines and maintenance of old machines, attention should be paid to
check the compression of the stator core and the pressure deviation of the
tooth pressure fingers, especially the toothing at both ends. If there is a
slack phenomenon, it should be processed before it can be put into operation.
If there is any doubt about the connection or the insulation of the core, the
iron loss test shall be carried out.
4. During manufacturing,
transportation, installation and overhaul, care should be taken to prevent tiny
foreign objects such as welding slag or metal chips from falling into the
stator core ventilation slots.
5. When the generator
insulation overheat alarm occurs, the cause should be analyzed, and if
necessary, stop and perform the defect treatment.
In daily operation, we
can take the above five measures to actively prevent and deal with the problem
of overheating of diesel generator sets. Once we find out the cause and solve
it in time, and it is good for generator set. Run to lay a solid
foundation.
