TESTING STAND FOR HYDRAULIC MACHINES OF FLUID POWER DRIVE Russian patent published in 2008 - IPC F15B19/00 

FIELD: technological processes.

SUBSTANCE: stand is intended for testing in production, operation and repair of hydraulic machines of fluid power drive. Stand consists of rotary drive, for instance, hydraulic, mechanically connected with regulated reversible loading hydraulic machine. This hydraulic machine is mechanically and hydraulically connected with tested hydraulic machine. Mechanical connection of rotary drive with loading hydraulic machine is arranged in the form of toothed gear, the free ends of shafts of which are equipped with couplings for connection with tested hydraulic machine. In hydraulic connection between tested and loading hydraulic machines, in parallel to the latter, at least one controlled throttle and hydraulic valve equipped with loading form setting device are installed, at that, hydraulic line of hydraulic valve control is supplied from head hydraulic line of rotary hydraulic valve, and drain is connected to non-loaded hydraulic line, which connects tested and loaded hydraulic machines.

EFFECT: reduction of production and operation costs.
