The air filter of the generator set is an air inlet device for filtering particles and
impurities in the working of a piston type generating set, which is
composed of two parts of the filter element and the housing. The main
requirements of the air cleaner is high filtration efficiency and low
flow resistance, long time of continuous use without maintenance. When
the generator works, if the air contains dust and other impurities, will
aggravate the wear parts, so it must be equipped with air filter.
The air filter is divided into 3 types, which are inertia type, filter type and oil bath type.
1. Inertial air filter:
due to particle and impurity density is the density of the air, when
the particles and impurities with air rotation or a sharp turn,
centrifugal inertia force, can make the impurities separated from
airflow.
2. Filter air filter:
guide the air flow through the metal filter or filter paper, the
particle and impurity barrier, and adhesion on the filter element.
3. Oil bath air filter:
air filter is arranged at the bottom of the oil pan, the oil will flow
sharp shock, particles and impurities in the oil viscosity and
separation. By stirring up the oil droplets, with air flows through the
filter, and the adhesion of the filter element. The air flows through
the filter element, further adsorption of impurities, so as to achieve
filter function.
Replacement cycle of air filter for generating units
Commonly used
generating units, every 500 hours to replace the air filter. Standby
generator set, working 300 hours or 6 months to replace the filter. The
usual maintenance of power generators, can remove the air filter, air
gun blowing, the replacement cycle can be extended to 200 hours or three
months.
Filter of air filter
for generating units: the filter is not necessarily a big brand, but can
not be used fake and shoddy filter.
