HYDRAULIC HOSE TEST BED Russian patent published in 2004 - IPC

FIELD: test equipment.

SUBSTANCE: bed has hydraulic system with hydraulic reservoir for working fluid, discharge and drain lines, working pressure pump for supplying working fluid from hydraulic reservoir to tested hydraulic hose through discharge line, aids for connecting hydraulic hose to discharge line and drain valve. Input of drain valve is connected with discharge line and output of valve is connected with drain line. Bed also has pressure transducer connected to discharge line, additional low pressure piston-type pump which is connected with discharge line in parallel to working pressure pump to provide quick filling of hydraulic system with working fluid. Working pressure pump has to be plunger-type pump; aids for connecting hydraulic hose to discharge line have quick removable clutches. At least one pump has foot drive. Bed is provided with capped chamber for placing hydraulic hose, drum for reeling hydraulic hose up during test and safety valve for limiting value of pressure in discharge line. Drain valve is made in form of plunger-type cock. Bed allows testing of long-length hydraulic hoses.

EFFECT: reduced working hours of testing: improved safety, reduced loss of working fluid.
