摘要
FIELD: machine building.;SUBSTANCE: plant comprises an oil filter, a tank with oil, a header, a safety valve for pressure fixation, electric motors, worm gears, a hydraulic pump, oil pipelines, a pressure gauge, a tubular sample, a crank mechanism and a breaker. The plant additionally comprises an electric motor with a worm gear and two hydraulic pumps. A yoke is fixed to a sample end. Three hydraulic cylinders are installed with stems, one of which contacts with the end of the tubular sample, and two other ones - with the yoke. The header is arranged in the form of three reservoirs joined together, to which two pressure gauges are introduced additionally, and two safety valves for pressure fixation, and also one stop valve is attached to each of two reservoirs, and two stop valves are fixed to the third reservoir.;EFFECT: expansion of functional capabilities by testing a tubular sample for twisting, bending and bending with twisting, both with and without internal pressure.;1 dwg
