As a key component of the wind power generation system, the operating stability and efficiency of the fan box are directly related to the performance and life of the entire system. As a supporting and rotating component, the design of the lubrication system of special bearings for fan boxes is particularly critical. These special designs not only ensure the good operation of the bearings under extreme working conditions, but also extend the service life of the bearings and equipment.
The lubrication system of special bearings for fan boxes first focuses on the selection of lubricants. For the high-speed rotation and heavy-load conditions of the fan box, high-performance lubricating oil or grease is usually selected. These lubricants have excellent extreme pressure anti-wear properties, antioxidant properties and rust prevention properties, and can maintain stable lubrication effects under high temperature, high speed and heavy load conditions. At the same time, in order to meet the operating requirements of the fan box under different climatic conditions, the lubricant also has good low-temperature fluidity and high-temperature stability to ensure that sufficient lubrication can be provided for the bearings under various environments.
In terms of lubrication methods, special bearings for fan boxes adopt a variety of special designs. For large fan boxes, oil bath lubrication or forced lubrication is usually used. Oil bath lubrication uses the oil pool in the bearing seat to store lubricants, and the bearings dip the lubricants for lubrication during rotation. Forced lubrication uses an oil pump to force the lubricant to the bearing to ensure that the bearings are fully lubricated even when rotating at high speeds. For small fan boxes, grease lubrication may be used to maintain the lubrication of the bearings by regularly adding grease.
In addition, the lubrication system of special bearings for fan boxes also focuses on the design of sealing performance. In order to prevent lubricant leakage and external impurities from invading, sealing devices are usually set between the bearing seat and the end cover. These sealing devices not only have good sealing performance, but also can adapt to the slight displacement of the bearing during rotation, ensuring long-term and stable sealing effect. At the same time, in order to reduce the friction and wear between the seal and the shaft, the sealing device also uses wear-resistant materials and special structural designs.
The lubrication system of special bearings for fan boxes is specially designed in terms of lubricant selection, lubrication method and sealing performance. These designs not only ensure the good operation of the bearings under extreme working conditions, but also extend the service life of the bearings and equipment.
