Regarding the high bearing temperature of Giti Nasir vane compressors
Thread Content
The company uses GEA rotary vane compressors to transport chlorine gas; the motor has a power of 185 KW, and the transmission is of the gearbox type. Concentrated sulfuric acid is used as the working fluid. Currently, the temperature of the bearings on the non-driving side of the unit is rising rapidly, reaching 100°C, while the temperature of the bearings on the driving side remains normal at 30°C. The vibration level is 2.5 mm/s. I would appreciate it if those who are available could help think through possible reasons for this phenomenon.
Dirt gets inside the machine, causing axial friction between moving and stationary parts, which results in excessive axial load on the bearings!
Inspect to rule out issues such as lack of oil in the bearings and the presence of foreign objects
Upon inspection, the working fluid inside the unit is normal with no foreign objects present, so this issue can be ruled out
