Cavitation water jet can take advantage of the power generated from vacuole rupture to enhance the performance of the jet. Studies have shown that the pressure of the cavitation jet is 8.6–124 times as high as continuous pressure in the same pump conditions, therefore the cavitation jet is widely utilized in cutting, cleaning and descaling. The study focused on blade-type cavitation washer, using...
Focused on the metal plastic forming of large-scale cut-off valve bodies used by power plant boilers, and based upon a deep study of combined backward cup-forward rod extrusion, this paper presents a new forming process named ''shear-extrusion'', of which the main characteristic is that it is labor saving. The new shear-extrusion process was studied by the methods of numerical analysis and simulating...
