Correct maintenance is an important guarantee to improve the service life of acid and alkali resistant fans

Release time: 2019/10/25 Clicks: 1903

Correct maintenance and maintenance is an important guarantee for the safe and reliable operation of the fan and an increase in the service life of the acid and alkali resistant fan. Therefore, when using the acid and alkali resistant fan, the maintenance and maintenance of the acid and alkali resistant fan must be paid full attention.

Impeller maintenance:

At the beginning of the impeller operation and all regular inspections, whenever possible, the impeller must be inspected for defects such as cracks, wear, and dust accumulation.

Whenever possible, the impeller must be kept in a clean state, and the dust and rust on it must be periodically removed with a wire brush, because with the increase of the operating time, it is impossible for these dusts to adhere to the impeller uniformly, resulting in Impeller balance is broken, causing rotor vibration.

Once the impeller has been repaired, it needs to be rebalanced. If possible, you can use a portable trial balancer to perform on-site balancing. Before performing balancing, all tightening bolts must be checked for tightening. Because the impeller has been running unbalanced for some time, these bolts may have become loose.

Bearing maintenance:

Always check the bearing lubricant supply. If there is oil leakage in the box, you can tighten the bolts of the end caps. If this is not possible, you may have to replace with new sealing packing.

The bearing lubricant should be replaced at least once in half a year during normal use. For the first use, it should be performed after about 200 hours of operation. The second oil change should be performed within 1 to 2 months. After that, the lubricant should be checked once a week. If the lubricating oil has not deteriorated, the oil change can be extended to once every 2 to 4 months. When replacing, you must use the specified grade of lubricating oil, and thoroughly drain and clean the old oil in the tank before filling with new oil.

If you need to replace the fan bearing seat, you should pay attention to the following:

Before installing a new bearing, the bearing and the bearing box must be cleaned. The bearing is placed in oil with a temperature of about 70-80 C and heated before being loaded on the shaft. It must not be forcibly assembled to avoid injury to the shaft.

Case maintenance:

Except for regular inspection of the casing and the interior of the intake chamber for serious wear and tear and removal of serious dust deposits, these areas may not be subject to other special maintenance. Regularly check whether all the fastening bolts are tight. For the fan with the compression bolts, press the butterfly spring on the feet to the installation height specified in the drawing.
