The lifespan of a fan is influenced by multiple factors, with the key factor being the operating environment

The operating environment of  a fan is one of the core variables that determine its lifespan. Different environmental factors directly affect the core components of the wind turbine (such as blades, towers, electrical systems, and transmission chains) through mechanisms such as corrosion, wear, and fatigue stress, ultimately affecting the service life of the entire machine.

1、 Climate conditions: the 'fundamental loss source' that runs through the entire lifecycle of wind turbines

Climate conditions are the most common environmental factors faced by wind turbines during operation, and their impact has the characteristics of "sustainability and accumulation". It mainly shortens the service life by changing material properties and accelerating component aging.
Temperature: High temperature accelerates the aging of lubricating oil, low temperature causes material brittleness, and extreme temperature can shorten the service life of components.
Humidity: High humidity environments can easily cause electrical component short circuits or metal corrosion.
Wind speed and turbulence: Long term high-speed operation or turbulence can intensify blade vibration, leading to fatigue damage; Frequent starting and stopping at low wind speeds increases mechanical wear.

2、 Geographical environment: Regional 'strong destructive factors' require targeted design

The influence of geographical environment has the characteristics of "regionalism and strong destructiveness". Wind turbines in different regions need to undergo "customized protection design", otherwise it may lead to rapid component failure (the lifespan may be shortened to one-third of the design value).
Salt spray and sand dust: Wind turbines in offshore or desert areas require special protection, otherwise salt spray corrosion or sand dust wear will quickly damage surface coatings and seals.
Earthquake and geological activity: In areas with frequent earthquakes, it is necessary to strengthen the seismic design of tower structures to avoid structural failure.

3、 Biological factors: 'Hidden damage' is easily overlooked, with significant long-term cumulative effects

The influence of biological factors often has a "hidden" nature, and initial damage is not easy to detect, but long-term accumulation can seriously affect the performance and lifespan of the fan.
