Change of technical state of spiral duct fan
The working efficiency of spiral duct fan equipment in use is actually affected by many factors. The small editor of spiral duct fan manufacturers sorted out several influencing factors affecting the working efficiency of spiral duct fan here today.
1. The role of surrounding medium energy, including the role of operators, repairmen and environmental conditions;
2. Internal factors related to the operation of spiral duct fan and the work of each mechanism, such as various loads, vibration, temperature, etc;
3. The latent energy gathered in the parts of spiral duct fan during manufacturing and assembly. These energy mainly exists in the form of mechanical energy, thermal energy and chemical energy. When the energy reaches a certain value, the parts will be damaged first, specifically manifested as wear, deformation, crack, fatigue, corrosion, etc, The appearance of damage will also change the structural parameters of spiral duct fan parts.

If the structural parameters of the main parts of the spiral duct fan reach the limit after long-term use, and the functional output parameters seriously exceed the limit, the economy of use will be significantly reduced. At this time, the spiral duct fan is in the technical state, so it needs to be overhauled or updated in time, The repaired spiral duct fan can be put into use only after the technical performance of each part reaches the standard.
Maintenance of spiral duct fan
1. Air duct prefabrication shall have an independent workplace, the workplace shall be flat and tidy, and the processing platform shall be leveled without concave convex places.
2. The site of double-sided aluminum foil insulation board air duct and other composite air ducts shall be dry, the space shall be large, and there shall be space for stacking finished products. The processing site shall reserve transportation channels for on-site materials, finished products and semi-finished products.
3. The spiral air duct machine shall be cleaned regularly. It can be cleaned with a hand-held direct air suction pipe, and the dirt can be removed by directly contacting the inner wall of the pipe with a brush. Using this method requires that the air duct has a large manhole, which can be accessed by the operator.
