Dynamic characteristic analysis of the piston pump with the valve plate outer dead center damage
Source abstract
Abstract
The piston pump is one of the key components of the hydraulic system. The valve plate, one of the key friction pairs of piston pumps, contributes most to the dynamical stability and operational reliability of the pump. Existing research on the valve plate of the piston pump does not mention the outer dead center (ODC) damage, which is necessary when considering the dynamic characteristics of the piston pump facing failure. This paper establishes a flow area model and a fluid-domain simulation model of the valve plate of the piston pump under normal and damaged conditions. The dynamic characteristics in the pressure and vibration signals under ODC damage are analyzed. A piston pump testing with ODC damage is carried on to verify the proposed models. The simulation and the experimental signals are compared by extracting the fault features of the valve plate ODC damage.
