Netizens ask questions:
How does the high-pressure accumulator work in high-pressure EH oil systems and when does it work?
Asahi replied: The high-pressure accumulator mainly balances oil pressure fluctuations in the pipeline. Specific analysis of a special example: when most of the oil motors of the system are quickly opened (such as the steam turbine starts to roll, 2 medium pressure regulating valves are opened at the same time, or the valve is switched at 2900 revolutions, 6 high regulating valves are opened at the same time), the system oil pressure The oil pump will inevitably fall at this time. At this time, the oil pump is too late to make a response. The accumulator is designed not only close to the oil motive, but also can replenish the system with oil more quickly than the oil pump. . The importance of accumulators plays an important role in high-pressure EH oil systems. The fluid is actually incompressible and cannot store energy, so the hydraulic accumulator uses gas (nitrogen) compressibility to store the fluid.
