Design of Hydraulic System of Microcomputer Governor for Small Turbine

“…The accumulator is filled with nitrogen gas at a pressure of 11MPa, and the energy of the oil is stored in the gas because of the compressible nature of the gas. The operation values of the three electric-contact pressure gauges 12 are set according to table 1, which are respectively used for start/stop control of working oil pump and standby oil pump, as well as high oil pressure alarm and low oil pressure accident shutdown [5]. The function of relief valve 4 is to discharge part or all of the oil from the oil pump outlet to the tank when the oil pump cannot be stopped for any reason, so as to avoid damage caused by high oil pressure of the hydraulic station and hydraulic servo system.…”
