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

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

Excellent compression performance and efficient energy storage
In addition to chemical stability, the compression performance of nitrogen is also a key factor in its becoming 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 efficient compression performance of nitrogen to convert excess hydraulic energy into compressed gas for storage. When the system needs additional energy, this stored energy can be quickly released to replenish the system pressure and ensure the smooth operation of the system under high dynamic loads.

Cost control and environmental protection considerations
In industrial production, cost control has always been the focus of enterprises. As a widely available and easily accessible gas, nitrogen has a relatively low production cost, which is undoubtedly a huge advantage for enterprises. In addition, nitrogen does not produce harmful substances during production and use, which meets the strict requirements of modern industry for environmental protection. Therefore, choosing nitrogen as the compressed gas for diaphragm accumulators not only helps to reduce the production costs of enterprises, but also helps to enhance the environmental image of enterprises.

Wide application and excellent performance
The combination of diaphragm accumulators with nitrogen as compressed gas has shown excellent performance in many fields. In high-precision applications such as precision machining and semiconductor manufacturing, the shock absorption and pulsation attenuation functions of diaphragm accumulators are particularly important. It can effectively absorb and attenuate the pressure and flow pulsations generated 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 fields of automobiles, aerospace, etc., diaphragm accumulators also play an important role, providing strong support for the stable operation of the system.
