Development of a Multifunctional Abrasion and Friction Test Bench with High Ambient Pressure for Seawater Hydraulics

Abstract:

Seawater hydraulic pump, of which the performances and service life are highly dependent on the structural design and material selection of the friction pairs and sliding bearing, are the power componentof the seawater hydraulic systems. Based on the previous studies, a seawater abrasion and friction test bench with high ambient pressure (≧20MPa) is to be developed for deep-sea (≧2000m) application environments. The technical requirements are presented and comparison analyses have been made between two testing schemes: rotating cylinder-blockscheme and rotating swash-plate scheme. Details are presented on the designs of the three key friction pairs and sliding bearing of the rotating cylinder-block bench. This research provides a test bench for the design of key parts in deep-sea water hydraulic pump/motor and the studies of the related theories (such as the friction and wear theory, lubrication and bearing mechanism).
