What Is the Function of Genset Air Filter
by Starlight Generator dieselgeneratortech
This article is mainly written
to introduce the function of diesel
generator air filter as well as its maintenance
period. If you are interested, then read on.
It is mainly used to filter the
particulates and impurities in the air so as to reduce the wear of the
piston rod, valve gear and the cylinder. Usually, the air filter consists of
two parts: filter element and shell.
In general, there are two types
of air filters, dry type and wet type.
A dry type air filter is a
filter that separates the impurities from the air through a dry type filter
However, a wet type air filter
includes oil-immersed and oil-bath two types. The main function of the
oil-immersed type filter is to separate the impurities from the air through the
filter element. The main function of the oil-bath type filter is to import the
dusty air into the oil tank to remove most dust.
Usually, air filtration has
three ways, inertia, filter and oil-bath way.
Inertia type: Because the density of the particles and impurities is greater
than the density of the air, when the particles and impurities rotate with the
air or take a sudden turn, the particles can be separated from the air flow
under the action of centrifugal inertial force.
Filter type: Guide the air to flow through
the metal screen or filter paper, so as to block the particles and impurities
and make them paste on the filter element.
type: Equipped with oil pan at the bottom of the air filter, using the
air flow to impact the oil to separate the particles and impurities and make
them stick in the oil; the oil droplets flow through the filter core with air
and adhere to the filter core.Air flows through the filter element, which can
adsorb impurities further, so as to achieve the purpose of filtering.
Genset air filter replacement
cycle: replace the filter when the common generator sets work every 500 hours;
replace it when the standby generator sets work for 300 hours or half year. In
addition, the genset maintenance
is also very important and necessary, which contribute to extend the
In general, the maintenance
period of the diesel generator air filter is conducted every 50 hours.
If the filter is not too dirty,
it can be directly blown with compressed air, but it should be noted that the
air pressure can’t be too big, besides, the nozzle can’t be too close to the
filter element. However, if the filter is too dirty, you should use
special cleaning fluid to clean it, and then blow it to dry. After the
cleaning is completed, check the air filter, use the light to lighting from
inside and outside, observe at the external of the filter, if found there is a
light-spot, it shows that the filter has been perforated, you should replace
the same type of the filter. If there isn’t a light-spot, it shows that the
filter hasn’t been perforated. You should be careful to install the air filter.
