ELECTROHYDRAULIC TEST PRESS Russian patent published in 2024 - IPC B30B1/32 B30B15/16 G01B13/24 G01L1/02 G01N3/10 

FIELD: test equipment.

SUBSTANCE: invention can be used for mechanical testing of samples of materials for strength in compression and bending mode. Press comprises loading module, programmable logic controller, pressure sensor and cable encoder. Loading module includes a base with columns, a fixed crossbar, on which a screw with a flywheel is fixed with possibility of movement. On the lower end of the screw there is an upper plate with guides to limit its rotation. Power hydraulic cylinder is fixed on the base. At the upper end of the rod there is a lower plate with a cable encoder drive fixed on it. Hydraulic cylinder is connected in series via proportional-distributing valve and hydraulic control valve of valve type with high-pressure oil pump. Proportional-distribution valve transfers volume of liquid to distribution plate. Programmable logic controller is connected with proportional-distributing valve, hydraulic control valve of valve type and electric motor.

EFFECT: result is expansion of functional capabilities, higher reliability and safety of use.
