Machine
Application
Centrifugal fan is a machine that relies on input mechanical energy
to increase gas pressure and discharge gas. It is a driven fluid
machine. Centrifugal fans are widely used in ventilation, dust
exhaust and cooling of factories, mines, tunnels, cooling towers,
vehicles, ships and buildings; ventilation and induced air of
boilers and industrial furnaces; cooling and cooling in air
conditioning equipment and household appliances Ventilation; drying
and selection of grain.

Repair and maintenance of centrifugal fan
Correct maintenance is an important guarantee for the safe and
reliable operation of centrifugal fan and the improvement of the
service life of centrifugal fan. Therefore, we must pay full attention to the use of centrifugal fans.
1. Repair and maintenance of impeller
In the early stage of impeller operation and all regular
inspections, whenever there is a chance, the impeller must be
inspected for defects such as cracks, wear, and dust accumulation.
Whenever possible, the impeller must be kept clean, and the dust
and rust on it must be regularly brushed with a wire brush, because
as the operation time increases, these dusts cannot be evenly
attached to the impeller, which is caused The balance of the
impeller is broken, and the rotor vibrates.
As long as the impeller is repaired, it needs to be dynamically
balanced. If possible, you can use a portable test balancer to
balance on site. Before performing dynamic balancing, it is
necessary to check whether all tightening bolts are tightened.
Because the impeller has been operating in an unbalanced state for
some time, these bolts may have been loosened.
2. Maintenance of the casing and air inlet chamber
Except for regular inspections of the casing and inlet chamber for
serious wear and tear, and removal of serious dust accumulation,
these parts do not require other special maintenance.
Regularly check whether all fastening bolts are tight.
FAQ
1. What parameters need to be provided when you design the
industrial centrifugal fans?
Answers: Air flow, total pressure or static pressure, inlet
temperature, local voltage and frequency, Altitude etc.
If there is flammable and explosive gas, or big dust loading in the
medium, please also inform the designer.
2. How about your company’s pre-sales service and after-sales
service?
Answers: Before our cooperation, we have the professional technical
team to help you make the technical solution according to your
working condition, to make sure the centrifugal fan efficiency
operation.
