TEST BENCH FOR TESTING PRODUCT FOR EFFECT OF EXTERNAL HYDRAULIC PRESSURE VARYING AT GIVEN RATE Russian patent published in 2025 - IPC G01N3/10 G01M3/28 

FIELD: testing.

SUBSTANCE: invention relates to the field of test equipment, in particular to the hydraulic tests of deep-sea devices (mainly large-sized ones) and allows to simulate the loads that occur when the devices are submerged at a given speed to a given depth, as well as during their surfacing. Proposed device comprises hydraulic chamber, pressure generating device, pressure control device and working medium tank communicated via pipeline with hydraulic chamber via pressure generating device. Pressure control device is made in the form of a pressure gauge installed on a container with a working medium. Device is equipped with at least one pipeline connecting the hydraulic chamber with a reservoir with a working medium made in the form of a receiver filled with compressed gas. Device for creating pressure in the hydraulic chamber is made in the form of a ball valve, an electromagnetic shut-off valve, a servo valve and a check valve installed in series on the pipeline connecting the receiver and the hydraulic chamber. Device for creating pressure in the hydraulic chamber is equipped with a filter and an electrically driven ball valve installed in series on a pipeline connecting the hydraulic chamber to the environment. Pressure control device is additionally equipped with a pressure gauge and a pressure sensor, which are installed on the hydraulic chamber.

EFFECT: improving reliability of control of parameters of articles during testing with reduction of costs for performance of works.
