2020-4-26rig but the lubrication film pressure in the friction interface was not taken into consideration in the experiments [10 11] The lubrication of composite slippers in a water-based axial piston pump/motor was also investigated by a self-designed test system and the results indicated the slipper surface polishing was necessary in pump/motor [12]

2016-6-30Jacobsen et al conducted the experimental research with colored fresh concrete flowing after ordinary concrete to observe the flow conditions and demonstrated the lubrication existence at the interface between concrete bulk and the pipe It was uncertain that the exact thickness of this lubrication layer in literatures was estimated to be between 1 and 5 mm (Austin et al 2000 Crepas 1997)

2020-2-1Lubrication regimes transition has significant effects on the operating stability and lifetime of the bearing-rotor coupled system For the actual bearing and rotor surface undoubtedly lubrication regime on the interface are extremely complicated and always in dynamic fluctuation states under different operating conditions

2014-2-25This paper describes some experimental studies about the effect of interface wettability on hydrodynamic lubrication film thickness by a custom-made slider bearing tester The lubricated contact pair consists of a fixed-incline slider and a transparent disc and a thin lubrication film can be generated when the disc rotates The film thickness was measured by interferometry

2020-6-26Furthermore how the shaft speed load pressure and slipper attitude influence the lubrication performance of the interface is analyzed The research shows that the slipper attitude has a significant effect on the pressure distribution

The application of emulsion for combined heat extraction and lubrication requires continuous monitoring of the quality of emulsion to sustain a desired grinding environment this is applicable to other grinding fluids as well Thus to sustain a controlled grinding environment it is necessary to adopt an effectively lubricated wheel-work interface
