| Summary: | Aiming at the fatigue fracture phenomenon of the pump's circlip,it is necessary to determine the circlip's fracture factors and formulate improving measures.By analysing the force of axial and radial movements of the circlip,it was determined that under normal assembly conditions,the axial impact generated during the opening and closing process of the valve will not lead to the fatigue fracture of the circlip.However,in the abnormal assembly state,metal impurities accumulated in slot and circlip's fillet smaller than the radius of the slot will cause frequent radial shrinkage of the circlip,which were the main factors for the fracture of the circlip.From the perspective of piston pump repair,circlip's fracture suppression measures such as controling the circlip and the slot matching size were formulated,which effectively reduced the possibility of the circlip sliding along the groove rounded trajectory.It is of certain significance to the maintenance application of the plunger pump. |
