摘要

testing of bellows. SUBSTANCE: device has bellows, moving and immovable supports-flanges connected rigidly to force loader-hydraulic drive consisting of hydraulic cylinder, piston and rod. Working fluid is supplied to and drained from upper and lower cavities of hydraulic cylinder through channels. Adjustment of stroke for stretching and compression is provided. Bellows tightness test is performed by supply of air into bellows through channel located in moving support-flange. EFFECT: enlarged functional capabilities. 1 dwg
