AI Technical Summary
In existing technologies, impurities in lubricating oil enter the lubrication system directly without effective filtration, leading to equipment wear or failure and affecting the reliability and stability of wind turbine units.
A lubrication pump oil inlet filtration structure for wind turbines was designed, comprising a filter cartridge and a filter plate. The filter plate and filter cartridge are cleaned by a motor-driven cleaning plate, and the filter plate and filter cartridge can be quickly replaced to ensure the cleanliness of the lubricating oil.
It achieves effective filtration of lubricating oil, reduces equipment wear, improves the reliability and stability of wind turbine units, and simplifies the maintenance process of filter plates and filter cartridges.
