FIELD: hydraulic engineering. ^ SUBSTANCE: bench for testing hydraulic cylinders has tank, controllable hydraulic pump, safety valve with pressure gauge, electrical hydraulic control valve, rod and piston loading device, meters of fluid leakages, and hydraulic cylinders interconnected through rods. The under-piston spaces are connected with the operation section of the electric hydraulic control valve via rod flow meters. The drain pipeline of the valve is connected to the tank through the rod loading device. The above-piston spaces of the cylinders to be tested are interconnected via piston flow meters connected in series and piston loading device interposed between them. ^ EFFECT: accelerated testing. ^ 1 dwg |
