Pressure Surge Analysis of a Test Bench for Biodegradable Hydraulic Oils

Abstract: A test bench for biodegradable hydraulic oils generates pressure surges by cyclic pressure loading. The parameters of these pressure surges (maximum pressure, amplitude, frequency etc.) are defined by the characteristics of the pressure valve and pipe line system. The response of the hydraulic system was recorded and studied in the case of four test bench modifications by comparing the maximum pressure, maximum pressure increase and the opening time of the pressure valve. The test bench with steel pipe between… Show more

“…The methodology for measuring the working fluid by loading the gear hydraulic pump was implemented according to the Vickers standard at 200 operating hours and corresponded to a dynamic load of 480,000 cycles, during which the GHD1-17R-S2D1-SG05G04-N hydraulic pump was loaded with pressure of 22.5 MPa for 0.5 s, with pressure of 18.5 MPa for 0.5 s, and with pressure of 0 MPa also for 0.5 s. The system itself was, thus, cyclically loaded. A similar approach was used in the work of the authors [8].…”

“…Producenci cieczy hydraulicznych zaopatrują w nie wiele gałęzi przemysłu, w tym takie dzie-dziny, jak m.in. obróbka drewna i maszyny rolnicze 1,2) , przenośniki, przemysł chemiczny i spożywczy oraz produkcja opakowań. W ostatnich latach moc systemów hydraulicznych znacznie wzrosła.…”
