Maintenance of Negative Pressure Fan Malaysia

Correct maintenance is an important guarantee for the safe and reliable operation of the negative pressure fan and the improvement of the service life of the negative pressure fan. Therefore, adequate attention must be paid to the use of fans.

1. Impeller maintenance: In the early stage of impeller operation and all regular inspections, as long as there is an opportunity, it is necessary to check whether the impeller has cracks, wear, dust and other defects.

2. Bearing maintenance: often check the bearing lubricating oil supply situation, if the box appears oil leakage, you can tighten the bolts of the end cover a little, so that it is not possible, consider replacing with a new sealing filler.

3. The negative pressure fan stops running for a long time, some parts are exposed to the air, and even the sun and rain, and the appearance is easy to rust. The exposure of the fan in the sun must be reduced, and it can not be shelved in the humid air for a long time.

4. In the northern region, the winter temperature is low, if the installation of negative pressure fan workshop or negative pressure fan operating environment is not good, we must pay attention to the anti-freeze problem of the fan, in the winter fan long-term use, the temperature is below zero, we must check the bearing box, the cooling water inside the clean.

5. The maintenance of electrical components is also very important, especially the motor, which is the most important power organ of the fan. When the fan is not used for a long time, it is necessary to do a good job of moisture-proof work. The workshop and the operating environment need to be ventilated and exhaust, and the Windows should not be opened on the wall with damp air and upwind.

6. When the fan is not used, it is necessary to run the main shaft and other components at regular intervals, so that the rotor rotates 180° to prevent the main shaft from deformation or even bending because of long-term static.

In addition to the above circumstances that require our special attention, we can not relax the maintenance of other aspects of the fan. To achieve regular maintenance of them, it is best to develop a complete set of maintenance and maintenance programs, so that the negative pressure fan will not affect its operating quality when it is started again, in order to extend the service life of the negative pressure fan.
