Not all hydraulic transmission systems require the participation of accumulators; some do not. So, what are the differences in their performance? The answer lies here. Firstly, regarding the use of accumulators, because this equipment itself has very high precision requirements, even during repairs, extreme caution is needed to avoid system leaks, which could lead to N2 leakage and hinder subsequent storage operations. The accumulator requires a relatively large amount of force during the initial pressurization; subsequent pressurizations will not be as effective.

　　The following describes the scenario without an accumulator. This is relatively rare in my country, but capitalist countries like those in Europe and America have long since abandoned its use, replacing it with advanced technologies like hydraulic hammers, which produce different results. Removing the accumulator also reduces costs because related problems are eliminated, and the overall structure becomes much simpler.

       Based on the above analysis, having or not having an energy storage device has different advantages. However, the technology in our country is not yet up to par, so there are still many situations where it is not needed. It is believed that this addition will not be necessary in the future.
