Cushion Ring Damage Mechanism and Its Improvement for Hydraulic Pile Hammers |
| |
| Abstract: | The text describes work principles of the hydraulic pile hammer and its cushion ring effect.And more,in view of air leakage at the hammer’s cushion ring the text analyzes the trouble cause and finds out the case lying in lower hardness value of the cushion ring material and high pressure borne instantaneously at the seal.We put forth an alternative to adopt a nested sealing ring to have solved such an existing problem successfully,while increasing reliability in the application. |
