Commonly problematic parts of stainless steel fans

The stainless steel fan is simply a kind of equipment for conveying gas, and its composition is not complicated. Stainless steel fan installation preparation

The main parts of a stainless steel fan are: impeller, volute, air inlet, bracket, motor, pulley, coupling, muffler, transmission (bearing), etc.

After the stainless steel fan is used for a long time, some parts will have problems under the influence of external factors or its own material factors.

Today, I will introduce to you which parts often have problems.

1. Gear

When designing the gear of the stainless steel fan, a certain amount of tooth wear is calculated. During normal use, its wear is negligible.

If the oil level in the gear box is high, it will cause too much oil to heat up during agitation, and the temperature at the bottom of the oil tank will be too high.

If you continue to operate in this situation, the gear will heat up and the gear may be affected by rapid wear, which will cause the impeller blades to contact or the unit to jam.

2. Bearing

The service life of the booster is closely related to the bearing.

Gradual wear may change the position of the shaft until friction occurs between the impeller and the cylinder block or top plate, and sudden bearing failure usually has serious consequences.

Because the impeller shaft assembly is no longer supported and correctly positioned, extensive damage to the casing and gear may occur immediately after the bearing fails.

3. Transmission shaft sealing components

The assembly is composed of two independent lip seals immersed in oil and located in the drive end cover.

If the oil level of the oil gauge rises, it means that the oil leakage through the inner member is excessive, and it should be replaced as an assembly.

Unless the seal or its bearing surface is damaged, the possibility of leakage through the outer member is unlikely.

In addition, the smoothness of the shaft also has a considerable influence on the performance of this type of seal. The operation problem may be caused by reasons other than component damage.

Since the gap is only a few thousandths of an inch, installation changes or pipe support changes may cause interference and friction.

Four, casing

Foreign matter entering the stainless steel fan casing can also cause some trouble.

If you encounter this type of problem, but you find that the inside of the casing is clean, please disconnect the pipe and loosen the mounting bolts, and re-level and align the driver.

After tightening the installation, make sure that all pipes are properly connected to the unit before reconnecting.

The above is the introduction about the problems with stainless steel fan parts. You must check and maintain it regularly during actual use.
