FIELD: testing.
SUBSTANCE: invention relates to the field of test equipment in mechanical engineering and can be used for dynamic testing of high-pressure hoses. Stand constitutes a metal structure containing a frame 19 with a tank 1 installed thereon. A pumping unit 2 is secured on the upper flange of the tank 1. The pumping unit 2 is connected to the hydraulic panel 18 installed on the frame 19 by a pipeline. Installed on the hydraulic panel 18 are: a check valve 3, whereto a pressure valve 4 and an inlet distributor 9 with an electromagnet 8 are connected by a channel. A pressure gauge 7 is also connected to the hydraulic panel 18 via a gate 6. A hydraulic accumulator 5 is connected to the channel of the hydraulic panel 18 used to connect the pressure valve 4 with the inlet distributor 9, thereby being located between the pumping unit 2 and the inlet distributor 9. An adjustable throttle 10 is secured on the upper wall of the frame 19 and located between the inlet distributor 9 and the tested hose 15. A pressure sensor 14 and an outlet distributor 17 with an electromagnet 16 are installed at the outlet of the tested hose. The pressure sensor 14 is electrically connected with the signal converter 12, the programmable logic controller 11, and the display 13, located in the control cabinet 20 secured on the frame 19. The electromagnets 8 and 16 of the distributors 9 and 17 are also electrically connected with the programmable logic controller 11.
EFFECT: expanded range of testing pressure change rate adjustment, guaranteed distribution of pressure along the entire length of the tested hose, and higher reliability of testing.
