To guarantee the reliability and performance of hydraulic systems, it is of vital importance to do hydraulic impulse testing for hydraulic components. However, the testing time is usually so long that the energy consumption is very large. An energy regeneration system with an accumulator is proposed and used for hydraulic impulse testing equipment. Mathematical analysis and simulations show that the hydraulic impulse testing system with an accumulator can reduce energy consumption by 15% compared with that of the system without an accumulator in the cycle. Furthermore, the energy efficiency of the hydraulic impulse testing system is increased from 62.82 to 75.71% by the use of an accumulator. Both simulation results and experimental results show that the control performance of the hydraulic impulse testing equipment with an accumulator is better than that of the equipment without an accumulator, and has a faster response speed and a larger pressure rise rate. Preizkušanje hidravličnih komponent s hidravličnimi impulzi je ključnega pomena za zagotavljanje zanesljivosti in zmogljivosti hidravličnih sistemov. Čeprav so aplikacije ponovnega pridobivanja energije močno razširjene v industriji, pa je med njimi le malo takih, ki bi bile razvite za opremo za preizkušanje hidravličnih impulzov. Standardi določajo, da trajajo impulzni preizkusi do 280 ur, kar pa je energijsko potratno in zmanjšanje rabe energije za impulzne preizkuse je zato zelo pomembna naloga. Hidravlični akumulator lahko hitro shrani in sprosti energijo, zato predstavlja dobro rešitev za regeneracijo energije v opremi za preizkušanje hidravličnih impulzov, kjer so cikli običajno zelo kratki. V članku je podan predlog sistema za regeneracijo energije z akumulatorjem kot del opreme za preizkušanje hidravličnih impulzov. |
