PNEUMATIC TEST BED FOR TUNING AND TESTING ELECTROMAGNETIC VALVE DISTRIBUTORS FOR PNEUMATIC DRIVES

摘要

FIELD: testing instruments. SUBSTANCE: device has chamber with socket for pneumatic distributor, compressed air source and pressure gage which are connected to chamber. Cross section of input channel from compressed air source and volume of chamber are equal to cross sections of input constrictor and volume of power cylinder respectively. Pneumatic chamber has two-position valve which provides through residual hole which section which is equal to one third of area of input constrictor of power cylinder. In addition it has sealed unit for tuning of electromagnet spring. EFFECT: possibility to model operations of pneumatic distributor in real conditions of pneumatic drive, simplified design of tuning. 1 dwgb
