PROCESS OF STRUCTURE TESTING FOR IMPACT ACTION OF TWO-PHASE MEDIA AND BED FOR ITS IMPLEMENTATION Russian patent published in 1995 - IPC

FIELD: testing equipment. SUBSTANCE: this testing process is realized on bed carrying cylindrical barrels 11 with separable skirt 13. Bed is also fitted with packings which contain cylindrical shell 8 and casing composed of outer 20 and inner 21 rings interjoined by means of rods. Mix of bed includes generator of high-pressure gas manufactured in the form of chamber 1 carrying return valve 5, electric heater 4 and pressure and temperature transducers 26 and 28 correspondingly. Pipe 6 which is uniaxially put into round hole of packing bottom is joined to outlet hole of chamber. Casing is tightly installed in ring clearance between outer surface of pipe and inner surface of shell of packing and is located between butt of pipe with rests and belt of overflow holes 10. Solid particles 14 are attached to bottom of barrel. Attachment members of tested structure are placed in front of open butt of packing and destructed diaphragm 23 shuts off gas path of ring nozzle. EFFECT: expanded functional capabilities by action of shock wave and hard particles on structure. 5 cl, 5 dwg
