Changing Judgment For Turbocharger Spare Parts

Whether the turbocharger spar parts need change or not is rely on many factors, such as ablation, wear and deformation. In daily life, you had better check turbocharger spar parts carefully.

Sealing ring will produce wear if the turbocharger working with dry friction intermittently. After disassemble, the sealing ring is difficult to recovery and its sealing will be decreased. At this time, you must replace it with a new one. The inner and outer ring of floating bearing are all in the oil film. At the same time, there is little wear. If you find the oil become dirty, oil film scratched or the bearing deformation, you should change floating bearing as soon as possible.

Generally speaking, thrust bearing plate will be without any wear if the oil is enough. But it is easy to plug oil hole if the oil become dirty. Then you may replace it according to the real situation. After the turbine shaft working for a period of time, the shaft surface will be in high temperature and its color will be changed too. As long as there is no obvious scratches and grooves of the shaft neck, you can continue to use. Inner hole wall of floating bearing will not wear due to enough oil supply. You could not change new one if there is no obvious scratch.

Take Good Maintain To Thrust Bearings

Generally speaking, thrust bearing is used on the parts which under axial load side and in high speed, such as crane hook, vertical pump, Hoisting jack and speed reducer. Bearing ring, seat and roller are separate and could assembly and disassembly respectively.

Pump which used just now usually should change the grease after working 100 hours. Then you can change it about 500 hours once. Thrust ball bearing which use grease had better change the grease 1500 hours once, filling oil quantity should be moderate. The thrust ball bearing will be heating because without appropriate amount of grease. In general, the gas volume had better in half or even more.

Container for lubricating oil and lubricating grease should be clean and also in good daily sealing. Dust, debris and other sundries can not exist. So that it will not damage trust ball bearing. Motor thrust ball bearings often use sodium base grease. This nature of the lubricating grease can be resistant to high temperature. But it can dissolve in water. So don’t this lubricating grease in trust ball bearing.
