Abstract:
After analyzed the failure mechanism of physics exploration hammer, the failure cause of the inner cylinder liner was mainly plastic deformation and eccentric wear, the failure cause of the piston was mainly abrasion on its outside part and fatigue failure on the end plane. The principal mode of abrasion was stuck wearing and abrasive wear. Finally, theilsu pwad to prolong the service life of hammer and some experimental investigation on the heat treatment to piston was also done.
Key words: hammer, wearing mechanism, improvement
