高压抗燃油液压控制系统运行 [ 日期2005-03-13 ] [ 来自网友...（Operation of high pressure anti fuel hydraulic control system [date 2005-03-13] [from net friend]...） Operation of high pressure anti fuel hydraulic control system [date: 2005-03-13] [from: netizen Network] The second chapter is running After the debugging of the EH system, it can be put into normal operation. 2.1 starting oil pump If the oil supply system in the environment of low temperature applications running on the need to start the heater, preferably not less than 20 DEG C long-term operation, in any case not less than 10 DEG C operation, the heater starts 15 minutes after the hand near the heater tank bottom, feel the heater is put to the oil temperature rose to 20 degrees above when to start the pump. Two main pumps can be mutually reserved, usually after 2 or 1 months, you can switch once, so that two pumps operating life is approximately equal. When the turbine is restarted for longer periods, the main oil pump must start the oil cycle 10 hours ahead of schedule. Filter pump can run for a long time, in order to ensure the cleanliness of the fuel tank and other oil, it is recommended that the filter pump run for a long time. If the main pump is to pump, you can start the filter pump in front of the feed tree, so that oil can be filtered on the one hand, and the oil temperature of the tank can be even on the other, especially when heating is started. 2.2 inspection The operator shall record the following parameters every 1 hours. Parameter name, typical value, permitted limit range EH system oil pressure 14.5MPa 11.2 ~ 17MPa The hydraulic pressure at the pump outlet is 0.2 to 0.5MPa higher than the hydraulic pressure of the system Work pump A or B A + B The tank level is 430~560 300mm The oil temperature of the tank is 30 to 55, and 20 to 60 centigrade The working pump works stably for a long time and the current is 20 ~ 25A 40A 2.3 parameter description 2.3.1 EH system oil pressure EH hydraulic system can be read
