Centrifugal fan daily maintenance, maintenance knowledge - bearing

Maintenance, correct maintenance of the centrifugal fan, it is safe and reliable operation of the centrifugal fan, the important guarantee of improving the service life of the fan. When using centrifugal fan, therefore, must cause enough attention. Today, xin feng small make up on the Internet to find some, centrifugal fan, the daily maintenance of information and share with you a centrifugal fan impeller maintenance: at the beginning of the centrifugal fan impeller and all regular check, as long as there is a chance, must check whether the impeller appear flaw, wear, dust and other defects. Whenever possible, must make the impeller must be kept clean, and regularly to use wire brush to brush the dust and scale and so on, because as the run time lengthen, these dust due to can't be evenly attached on centrifugal fan impeller, and balance the centrifugal fan impeller damage, so that cause the rotor vibration. As long as the centrifugal fan impeller repair, you need to make dynamic balance. If there are any conditions, you can use the portable test of dynamic balance instrument in the field of balance. Before a dynamic balance, must check whether all set bolt tightening. Because of centrifugal fan impeller has run under unbalanced state for a period of time, the bolt looseness may have. Centrifugal fan bearing maintenance: check centrifugal fan bearing lubricant oil supply situation, if appear the oil box, can put the end cover of the bolt tightening, so also not line, may have to switch to the new packing. Centrifugal fan bearing lubricating oil during normal use, should be replaced at least once half a year, when used for the first time in about 200 hours after the operation, the second oil change in 1 ~ 2 months time, after should check the oil once a week, such as lubricating oil without metamorphism, the oil change work can be extended to 2 ~ 4 months, provisions must be used when the brand lubricating oil ( On the general regulations) And the old oil within the tank after put clean and clean thoroughly to insert the new oil. If you want to for centrifugal fan bearing replacement, attention should be paid to the following items: before the new bearing load, must take the bearing and the bearing box is very clean. Put the bearing temperature is about 70 ~ 80 ℃ in the oil heating again after loading shaft, shall not be forcibly assembly, to avoid injury axis. Centrifugal fan of the rest of the equipment maintenance: all equipment including motor, electric actuators, maintenance of instruments, meters and so on can be found in the respective operating instructions. These operating instructions are provided by the various manufacturers, our factory will random packing these instructions provided to the user.
