... materials for working elements, improvements in construction, and optimization of the slurry flow are all various ways of softening the consequences of erosion wear that reflects on the working life of the hydraulic transportation pump’s elements. Data, which would be used for acquiring the above mentioned...

... in an actual application. The performance of a hydraulic axial piston pump with DLC-coated piston shoes was evaluated in a newly designed, dedicated hydraulic test system using fully formulated biodegradable, synthetic ester oil. For comparison, an equal but separated hydraulic system with a conventional...

... for asperity height, where the load capacity and friction coefficient are optimized. These optimum heights were reached at 1 – 3 μ m . Although the lip seal surface is considered to be smooth, reverse pumping can still be obtained using an oriented triangular design. The Couette flow rate for this asperity...

...Larry A. Villasmil; Dara W. Childs; Hamn-Ching Chen Multistage centrifugal pumps and compressors are among the most widely used pieces of rotating machinery in industry. A typical application demands the arrangement of several impellers or wheels mounted on a shaft that spins within a stationary...
