Except for removing serious dust accumulation, these parts may not be subject to other special maintenance. Regularly check whether all fastening bolts are fastened. For side channel blower with compression bolt, compress the butterfly spring on the foot to the installation height specified in the drawing. It is also necessary to check the lubrication system of the side channel blower frequently. As we all know, once the lubrication system of the side channel blower has problems, the bearing of the fan is likely to have excessive temperature, which is not conducive to the operation of the fan. If there is oil leakage in the box, the bolts of the end cover can be tightened a little. If this does not work, it may be necessary to replace it with a new sealing filler.

When the bearing lubricating oil is used normally, it should be replaced at least once in half a year. When it is used for the first time, it should be carried out after 200 hours of operation. The second oil change should be carried out in 1 ~ 2 months. After that, the lubricating oil should be checked once a week. If the lubricating oil does not deteriorate, the oil change can be extended to once every 2 ~ 4 months. The specified brand of lubricating oil must be used when replacing, The old oil in the oil tank shall be completely drained and cleaned before filling with new oil. Once there is a problem with the bearing of the side channel blower, it is necessary to replace the new bearing in time.

Place the bearing in oil with a temperature of about 70 ~ 80 ℃ and heat it before installing it on the shaft. Do not forcibly assemble it to avoid damaging the shaft. Therefore, the maintenance of the bearing of the side channel blower is not a simple thing. Once the user ignores what has not been done well, there is still a great risk in the bearing of the fan. Therefore, when using the fan, the safety of the fan bearing must be checked in advance to ensure that it is correct before starting the fan. This can also make the fan play a full role in use.
