Impact Analysis of Worn Surface Morphology on Adaptive Friction Characteristics of the Slipper Pair in Hydraulic Pump. [PDF]

Micromachines (Basel), 2023
The hydrostatic bearing slipper pair of the hydraulic pump has a unique adaptive friction characteristic, which has a better friction reduction and anti-wear ability than the general sliding friction pair, and also has a certain recovery effect on the ...

Analysis of Slipper Overturning and Collision Behavior of the Axial Piston Pump Based on Rigid-Flexible Coupling

IEEE Access, 2023
In the working process of the axial piston pump, the composite multi-degree motion of the slipper and its coupling, as well as the complex working conditions, cause the slipper to overturn and collide irregularly with its coupling. The overturning of the

Study on the Lubricating Characteristics of the Oil Film of the Slipper Pair in a Large Displacement Piston Pump

Lubricants, 2023
Due to the large size of the bottom surface, the slipper pair of the large displacement piston pump (LDPP) will form a larger linear speed difference in the inner and outer positions of the slipper relative to the center of the swash plate during high ...

Fault Diagnosis Method for Axial Piston Pump Slipper Wear Based on Symmetric Dot Pattern and Multi-Channel Densely Connected Convolutional Networks. [PDF]

Sensors (Basel)
Fault diagnosis in axial piston pumps is key to ensuring the proper operation of a hydraulic system. Slipper wear, as a typical fault in piston pumps, is challenging to accurately diagnose because the faults are very similar for different forms and ...
