Why is nitrogen chosen as the compressed gas for membrane accumulators?

Nitrogen, as one of the most abundant gases in the atmosphere, provides a reliable guarantee for the stable operation of diaphragm accumulators due to its unique chemical inertness. In hydraulic systems, accumulators must stand high-pressure environments for a long time and frequently store and release energy. This requires that the compressed gas inside has good chemical stability to avoid chemical reactions under high pressure, high temperature or when in contact with other media, which will lead to performance degradation or safety hazards. Nitrogen, with its property of not easily reacting with other substances, perfectly meets this requirement and ensures the long-term stable operation of accumulators under difficult working conditions.

Excellent compression performance and efficient energy storage
In addition to chemical stability, the compression efficiency of nitrogen is also a key factor in making it the preferred compressed gas for diaphragm accumulators. Nitrogen has a high compression ratio and can store a large amount of energy in a relatively small volume. This means that in hydraulic systems, diaphragm accumulators can use the compression efficiency of nitrogen to convert excess hydraulic energy into compressed gas for storage. When the system requires additional energy, this stored energy can be quickly released to replenish the system pressure and ensure smooth operation of the system under high dynamic loads.

Cost Control and Environmental Protection Issues
In industrial production, cost control has always been the focus of enterprises. As a widely available and readily available gas, nitrogen has a relatively low production cost, which is undoubtedly a huge advantage for enterprises. In addition, nitrogen does not emit harmful substances during production and use, which meets the strict environmental protection requirements of modern industry. Therefore, choosing nitrogen as the compressed gas for membrane accumulators not only helps reduce the production costs of enterprises, but also helps improve the environmental image of enterprises.

Wide Application and Excellent Performance
The combination of membrane accumulators with nitrogen as a compressed gas has shown excellent results in many fields. In high-precision applications such as precision machining and semiconductor manufacturing, the shock absorption and pulsation damping functions of membrane accumulators are especially important. It can effectively absorb and attenuate the pressure and flow pulsation caused by the rapid action of pumps and valves, protect precision instruments and key equipment from damage, and improve product quality and production efficiency. At the same time, in the automotive, aerospace, etc., diaphragm accumulators also play an important role in providing reliable support for the stable operation of the system.
