How to deal with vibrations caused by severe wear in the bearing area of high-temperature fans

High-temperature fans in the cement industry are key equipment in the entire clinker production process. Generally speaking, they have high power, poor operating conditions, large flow rates, and high speeds. A certain company's high-temperature fan has bearing position wear, resulting in high vibration values during production operation. The bearings are damaged, and there is no effective solution on site.

Online Repair Technology for Bearing Wear of High-Temperature Cement Fans

A certain cement company's high-temperature fan shaft is worn out, with a shaft diameter of 220mm, a bearing width of 70mm, and a wear amount of about 1.5mm. For the bearing wear issue of high-temperature fans, the traditional method is generally to transport the shaft to the machine repair workshop for welding and sleeve insertion. The welding machine processing process itself is prone to generate local thermal stress on the shaft surface, posing a risk of shaft fracture.

What are the causes of high-temperature fan vibration and the measures to address them?

The model of the high-temperature fan at the kiln tail of a certain company's 1000t/D production line is W6-2×29-46№ 21.5F, with a typical speed of 1000~1200r/min. The allowable values for bearing vibration of the high-temperature fan are: amplitude 0.198mm, vibration speed 11mm/S; the alarm temperature for the bearing is 75℃, and the shutdown temperature is 95℃; the alarm temperature for the hydraulic coupler oil output is 80℃, and the shutdown value is 85℃. The bearing housing has experienced significant vibration multiple times during production. Initially, this was mainly caused by poor ventilation in the fan pipeline.
