The recovery price of
used diesel generators is mainly affected by the brand, power, year and other
factors etc., including engine brand and generator brand. Because engine and alternator
is the main part of diesel genset.
As time goes on, diesel
generator sets depreciate year by year, that is to say, the longer the year is,
the less price it is, and the greater the power is, the more valuable it is. In
generally, brands are divided into imported brands, domestic first-line brands,
and other domestic brands. The recovery price will be different with different
brands.
How
to judge the recovery price of used diesel generator set?
1.It is necessary to
know the history, usage and sales reasons of the diesel generator set, as well
as the past maintenance situation and which important parts have been replaced.
Know what are the problems in use, so as to understand the wear condition of
diesel generator set more comprehensively and systematically.
2.Check the mechanical
parts of the unit for wear or fatigue by visual inspection. If problems are
found, replace them and better use the parts recommended by the manufacturer.
3.Through the complete
weld, check the electrical components and complete winding at the same time,
carry out the breakdown test on the wire insulation, and replace any parts that
do not meet the requirements of the trademark.
4.Replace the bearings
and bushings to ensure that these areas are not damaged by the inability to
operate the generator set. It is difficult to test whether the bearing and
sleeve affect the operation of the generator. Therefore, from the point of view
of safety, it is a better way to replace the bearing and shaft sleeve.
5.Observe the oil
pressure, water temperature, frequency and voltage. If the oil pressure is too
low and the water temperature is too high, you should be alert. It is easy to
cause serious damage to the generator set. The frequency and voltage are to see
whether the circuit is normal.
6.Carefully check the
used diesel electric generator by shaking the crankshaft, traction flywheel,
starter, etc.
How
to distinguish between refurbished and used generator sets?
Maybe many people
refurbished generator set and used generator set is the same, but actually,
they are not. We can check the difference by these methods:
1.Some parts of the
original generator are different from the color of the generator set, while the
refurbished machine is painted, so the color of the generator set is all the
same. Pay attention when the color of the generator set is all the same from
any point of view.
2.Start the generator to
see the instrument: when the renovated generator starts, the water tank
temperature is slow, while the new unit is fast.
3.Check the nameplate of
the generator. The generator set must have a nameplate, which is equivalent to
the ID card of the generator, and the generator without a nameplate is
equivalent to a unqualified product. We can check with the manufacturer on the
nameplate.
4.Touch the smoke
exhaust pipe by hand to see if there are not many black substances in it. If
there are more black substances, it is likely to be a refurbished machine.
5.How about the load
capacity? Generally, if the use time is too long, its performance will decline,
and its load capacity will be poor. Therefore, it is necessary to carry enough
load during the test. You'd better increase the load from 30% to full load to
see how it performs.
Of course, there are
many methods to judge the value of a used diesel generator set, also many
factors affect its value. We should check it according to the actual
situations.
Due to the wide
application of diesel generators, the quality of diesel generators is
different, and the market is mixed. Even some businesses directly take out the
used unit renovation as a new unit to sell, and often only report the brand of
diesel engine or generator, not say the original place, the unit brand in the
conversation process. So, if you plan to buy a used diesel genset, you must to
check clearly.
