what factors can cause dryer fan failure？How to avoid?
0
1Usually, the manufacturer requires
customers to clean the filter element of a dryer every 3 days and replace it
every 3 months.
Due to negligence or a fluke mentality,
users fail to clean and replace it in time. This will lead to poor airflow and
excessive fan temperature.
0
2Due to the interruption of water supply,
the water in the condenser evaporates at high temperature, and the return air
temperature cannot be cooled, resulting in excessive fan temperature.

3desiccant wheel dryer: Since the rotor keeps rotating 24 hours a day, the silicone pad of
the rotor base is aged and worn seriously, resulting in air leakage and
cross-flow. The rotor belt is stretched and loose, and the rotor stops
rotating. Since the rotor is made of silica gel and molecular sieve fired at
high temperature, the heat resistance is low. When the rotor stops rotating,
the heating temperature of the regeneration area is too high, and the rotor
will burn and be damaged.
two desiccant bed dryer: The regeneration process requires switching valves, and the
switching frequency is about once every 4-6 hours. If the valve is not switched
in place or the silica gel is aged, it will also cause leakage and cross-flow.
The fan temperature is too high.

4Most manufacturers use high-temperature
hoses to connect the main unit of the dehumidifier. When checking the internal
unit of the equipment, the hose is damaged by mistake, or the hose is aged and
collapsed due to long-term use, which leads to fan overload and high
temperature. Eventually, the fan is damaged.

1In addition to judging the air volume
attenuation based on the air volume system, Jinyue Machinery has added filter
element pressure difference monitoring and separate filter element warning
light to give the greatest attention to the filter element.

2In order to ensure the reliability of the
system, Jinyue Machinery has dual temperature monitoring at key positions, such
as the drying and heating position and the regeneration and heating position,
to avoid inaccurate temperature measurement due to the relationship between the
measurement points, resulting in raw material agglomeration and significant
losses.

3As the only mechanical displacement part of
the whole machine, Jinyue Machinery attaches great importance to it and adds
magnetic switch monitoring points to accurately judge the accuracy of the
cylinder stroke position and movement time, and give reminders in the all-round
fault monitoring system.

4Drying tech J combines air flow analysis
with industrial design to connect all stainless steel pipes to avoid pipeline
damage, stratification, and collapse caused by the filter element not being
cleaned in time and the excessive negative pressure of the fan, which further
causes huge sequelae such as fan damage and fire.

5With all-round data support, through 24-hour data collection, automatic and manual analysis of the system, the system status can be judged and anticipated, equipment problems can be discovered in advance, and small problems can be prevented from developing into big problems. Jinyue Machinery after-sales engineers have a more intuitive understanding of the equipment status and interact with on-site mechanics in real time, just like being there in person. At the same time, free software upgrades are available for life to continuously improve the equipment.
