Water ring vacuum pump bearing 30 reasons summary

Water ring vacuum pump in the process of using the bearings often appear abnormal sound, these sounds may be caused by external causes, may also be a pump inside a problem, if not handled in time, it may be a pump By fatal injury. Water ring vacuum pump bearing 30 major causes of abnormal sound Summary So water ring vacuum pump bearing abnormalities what are the main reasons? Fluid Network Xiaobian sorted out the 30 possible causes for you, I hope for your help. 1. Grease is contaminated; 2. Lubrication is insufficient (oil level is too low, improper storage leads to leakage of oil or grease through the seal); 3. Bearing clearance is too small or too large (manufacturer's problem); Sand or carbon particles and other impurities, played the role of abrasive; 5. Bearing mixed with water, acids or paint and other dirt, played a corrosive effect; 6. Bearings are seat clamp flat (seat hole roundness is not good , Or seat hole distortion is not straight); 7 bearing housings on the underside of the horn (resulting in seat hole deformation or even bearing cracks); 8 bearing seat hole debris (residual chips, dust particles, etc.) 9. Seals eccentric (encountered adjacent parts and friction); 10. Bearings are subject to additional load (bearing axial tightness tight, or a shaft with two fixed-end bearings); 11. Bearings and shaft with Too loose (the diameter of the shaft is too small or the sleeve is not tightened); 12. bearing clearance is too small, too tight when rotating (tight sleeve tightened too much); 13. bearing noise End surface or steel ball caused by slip); 14. The shaft thermal elongation is too large (static bearing indefinite axial additional load); 15. The shoulder is too large (bearing seals and friction); 16. Block hole (The bearing seals seal distorted); 17. The labyrinth seal gap is too small (with the shaft friction); 18. Lock washer tooth bending (bearing friction and friction); 19. The location of the slinger is not suitable (hit the flange cover and friction occurs); 20. There are pressure pits on the ball or roller (caused by striking the bearing with a hammer when installed); 21. The bearing is noisy Vibration source interference); 22. Bearing discoloration and deformation of the heat (using the gun to remove the bearing heating caused by); 23. The shaft is too thick to make the actual match too tight (causing the bearing temperature is too high or noise); Small (causing the bearing temperature is too high); 25 bearing hole diameter is too large, the actual match is too loose (bearing temperature is too high - outer ring skid); 26. bearing seat hole becomes larger (non- Large, or due to thermal expansion and larger); 27. Cage fracture; 28. Bearing raceway rusting; 29. ​​Ball, raceway wear (grinding machining failure or product bumps); 30. Ring raceway Unqualified (factory problem).
