Abstract: |
Through the analysis of the effect on FOD (foreign object debris) controlling by the structural and processing characteristics of the lower closed chamber of the small hole in the surface of the piston rod, the thesis adopts such processing methods as screw choke plugging, ultrasonic variable reciprocate flushing, repeated blowing and cleaning by filling cleaning agent and high pressure gas etc, to achieve the effective controlling of FOD in the lower closed chamber of the small hole. |
Key words: piston rod;lower closed chamber;FOD controlling |
