High temperature resistant centrifugal fanThere are several parts and components, and each part fully exerts its key function. The bearing is one of the key parts. During the whole process of operation, the machine and equipment rely on the bearing to promote the operation. If the bearing is Invalid conditions will result in the failure of all machinery and equipment to be used normally. It is necessary to immediately find the cause of the invalidation of the bearing. Let me introduce the reason of the invalid bearing.
1. The bearing load of the high temperature resistant centrifugal fan will destroy the lubricating oil film of the bearing and cause damage to the bearing. The cause is that the angle of view of the fan blades is adjusted too large; the rotating part and the stationary part have friction; the transmission belt of the transmission system is too tight; the gap in the bearing work is too small and the running time is too long.
2. Problems at the lubricant level. The key is because the viscosity of the lubricating oil is too high or too low; there are residual particles in the lubricating oil; the lubricating oil contains water to make the oil emulsion and the lubricating oil insufficient.
3. For the sake of spare parts and assembly line. The quality of the spare parts is not good; the bearing turnover body and the surface of the ropeway are not smooth and the precision is low; the bearing oil gap is too large; the shaft and level of the high temperature resistant centrifugal fan are not vertical; some leaves are damaged; The flatness of the fan shaft and the motor shaft exceeds the standard and other factors.
4. In summer, due to the pouring of the fire-fighting spray, the bearing box lubricating oil emulsion causes the bearing to be ineffective. It indicates that the key element of the frequent maintenance of high-temperature centrifugal fans is that the bearing box lubricating oil emulsion causes damage to the fan bearings, which causes the rotating parts of the fan to become static. Pieces are damaged and shaken. Frequent maintenance of the fan not only consumes a lot of spare parts, but also expands the labor efficiency of maintenance workers, and also creates safety hazards to production safety. Therefore, it was decided to carry out partial renewal and transformation of the fan, and a set of moisture-proof system software for the design of the fan.
The above is the root cause of the ineffective high-temperature centrifugal fan bearings. Therefore, when working with machinery and equipment, pay attention to the inspection of each part. It is very important to check the air intake system to avoid poor lubrication. When the bearing is unable to perform normal work, the maintenance of the machinery and equipment on time can improve the working efficiency of the machinery and equipment.
