This article first self-healing techniques are discussed , explored its causes , classification , status , application and development. For high-speed rotating fluid machinery common axial displacement fault , we propose a new type of axial displacement fault self-recovery system (Fault Self-recovery System), the system can be online real-time monitoring of shaft displacement by adjusting the pressure on both sides of the balance disc to adjust the axial displacement , to avoid malfunction. Laying the foundation for industrial applications , we have designed a laboratory axial displacement fault self-recovery bench . We build a finite element model of the rotor system , the use of Samcef rotor system software analysis and calculation , design a multi- disc rotor balancing bench for active research . In addition , we Shijiazhuang simulated flue gas turbine , gas turbine design simulation platform . Through comprehensive consideration and careful calculation, we make the experiment station has an axial displacement fault self-recovery for research, two for single span , multi- span rotor dynamic performance of experimental studies, three studies conducted unbalanced shaft coupling alignment and six -dimensional study , four studies conducted honeycomb seals , five for gas turbine simulation experiment , six for gas turbine shaft imbalance and excessive vibration when using electromagnetic balance head for active balance studies six functions .
