Centrifugal air compressor impeller | IHI Sullair centrifugal air compressor oil filter

Use appropriate and accurate installation tools. Try to use special tools, and try to avoid using things like cloth and short fibers. To prevent bearing corrosion, when handling the bearing directly by hand, wash off the sweat on your hands and apply high-quality mineral oil before operating. Pay special attention to rust prevention during the rainy season and summer. However, under certain special operating conditions, bearings can obtain a longer life than conventional calculations, especially under light loads. These special operating conditions are when the rolling surfaces (rails and rolling elements) are effectively separated by a lubricating oil film and limit possible surface damage caused by contaminants. In fact, under ideal conditions, so-called permanent bearing life is possible. Among the numerous maintenance records of centrifugal air compressors, there are many issues related to bearing maintenance. Bearings are the core component of centrifugal air compressor operation failures and determine the operating efficiency of the entire equipment. Excessive bearing temperature is a common failure in air compressor operation. Temperature failure mainly shows that the aperture of the bearing's oil inlet throttle ring is too small, the oil inlet volume is insufficient, the oil pressure of the lubrication system drops or the oil filter is clogged, the oil inlet volume is reduced, the cooling water volume of the oil cooler is insufficient, and the oil inlet temperature is too high. According to these fault phenomena, the actual treatment process requires overhauling the oil pump and oil pipe of the lubrication system or cleaning the oil filter to adjust the water inlet volume of the oil cooler cooling water. The aperture of the oil inlet throttle ring of the bearing is too small and the oil inlet volume is insufficient. Increase the throttle appropriately. Check the flow circle aperture to inspect the oil cooler, troubleshoot water leakage or replace with new oil.
