有三个问题问各位大哥，
1.350左右发动机是一致的么？
2. A350液压发动机驱动泵一个发动机上有2个，它是5000Psi，流量是多少？以及其他性能参数怎么样？

请问上述材料去哪里查阅。

等国内运行了350再问吧

1、一致
2、System Description Ref. Fig. Main Hydraulic Power - System Description There are two main hydraulic-power systems, the Green and the Yellow system. These two hydraulic systems operate at the same time. Each hydraulic system operates independently. There is no hydraulic fluid flow between them. When the engines are in operation, four engine pumps (two engine pumps for each engine) automatically pressurize the two hydraulic systems. Each engine operates one Green engine pump and one Yellow engine pump. When the engine pump operates, it pressurizes the hydraulic system to 5000 psi (344.74 bar) for the operation of the hydraulic consumers. When the electric pump is in operation, the hydraulic system pressure-indication is: - In green, when the hydraulic pressure is more than 2610 psi (179.95 bar) - In amber, when the hydraulic pressure is less than 2610 psi (179.95 bar). When the electric pump is not in operation, the hydraulic system pressure-indication is: - In green, when the hydraulic pressure is more than 2900 psi (199.95 bar) - In amber, when the hydraulic pressure is less than 2900 psi (199.95 bar). Each main hydraulic-power system has temperature control valves, which keep the hydraulic fluid at a temperature between 20 deg.C (68.0 deg.F) and 95 deg.C (203.0 deg.F). The temperature control valves increase the temperature of the hydraulic fluid and the hydraulic heat exchangers decrease the temperature of the hydraulic fluid to keep the temperature of the hydraulic fluid in the correct limits. The Green hydraulic-power system supplies the hydraulic power to the MLG and its related doors, the Ram Air Turbine (RAT) retraction and the flight controls. The Yellow hydraulic-power system supplies the hydraulic power to the NLG, the cargo doors and the flight controls. The pressurized hydraulic fluid from the engine pumps goes to the related hydraulic reservoir to pressurize the reservoir. There are hydraulic filters installed in the hydraulic system manifolds. They remove dust and solid particles from the hydraulic fluid to prevent damage to the hydraulic consumers. The hydraulic-fluid distribution system has hydraulic pipes which supply pressure at specified values. The nominal pressure values for the hydraulic pipes are: - 5080 psi (350.25 bar) for the high pressure line - 1000 psi (68.95 bar) for the low pressure line - 435 psi (29.99 bar) for the case drain line - 210 psi (14.48 bar) for the suction line. Each main hydraulic-power system has a hydraulic reservoir. When the aircraft engines operate the engine pumps, suction causes the hydraulic fluid to flow out of the hydraulic reservoirs and into the related engine pumps. The suction pipe between each engine pump and the related reservoir has a Fire ShutOff Valve (FSOV). The FSOV isolates the engine pump from the hydraulic system and prevents leaks. The hydraulic fluid from the return line of the hydraulic consumers flows back to the hydraulic reservoirs. For servicing of the aircraft on the ground, two Ground Service Panels (GSPs) are installed in the belly fairing. The GSPs have the necessary hydraulic connection ports, switches and gages.
