WebAnother option uses a porous media, or “frit”, to reduce the cross-sectional area (the lower restrictor in the Figure 1). Instead of just one straight hole, frits channel the gas through hundreds of pores in a central plug. Although generally more expensive than a simple laser-drilled plate, these offer a number of advantages.

WebThe porous restrictor was proposed by Panzera et al. [11], being designed based on a cementitious composite reinforced with silica microparticles via cold uniaxial pressing. This composite reaches 30% of porosity and 1.14x10-15m² of viscous permeability coefficient. WebThe porous bearings impregnated with the diphase fluid were run additionally with external lubricant and the results of the experiment led to the following conclusions: (i) ... 2.3.4 …
WebMar 13, 2024 · Abstract. The hydrostatic journal bearing equipped with a carbon-fiber-reinforced carbon-based porous bushing is employed in the hydraulic turbomachine. The bearing exhibits high load capacity, but may unduly consume pressurized lubricant. This study aims to maximize the load capacity and minimize the feeding power. The journal …
WebThe porous restrictors are fixed on the base plate. There are gas flow channels in the base plate leading to the porous restrictors. High pressure gas flows through the gas flow channels and the porous restrictors, and then forms an uniform gas film between the aerostatic gas-floating plate and the three-dimensional vibration platform. WebThe differences between the calculation results and the experimental data for both ceramic and graphite porous restrictors were less than 10%, which demonstrated that the permeability for compressible gas flow through a porous restrictor in aerostatic bearings can be accurately predicted by the fractal calculation method. 展开
