Bladder Accumulator is the energy guardian in the hydraulic system. What are its working principles and advantages?

The core of Bladder Accumulator lies in its ingenious structural design. It mainly consists of an elastic airbag, a pressure container and a sealing device connecting the two. The airbag is filled with inert gas. When the pressure of the hydraulic system increases, the hydraulic oil is pumped into the accumulator, the airbag is deformed by pressure, and the gas volume is reduced, thereby storing hydraulic energy. When the system needs to replenish energy, the airbag expands under the action of the internal gas pressure and releases the stored hydraulic oil to meet the system needs.
This design not only ensures the complete isolation of gas and hydraulic oil, but also realizes the efficient storage and release of energy through the elastic deformation of the airbag. At the same time, the high-strength material and precise manufacturing process of the pressure container ensure the safety and reliability of the accumulator under high-pressure environment.
As an auxiliary power source for the hydraulic system, Bladder Accumulator can store excess hydraulic oil when the system demand is low, and release it quickly when the demand increases, so as to achieve a smooth transition of energy. This not only reduces the capacity requirement of the hydraulic pump, but also reduces the energy consumption and operating cost of the system; the hydraulic pump will generate pulsation during operation, affecting the stability of the system and the service life of the components. The Bladder Accumulator effectively attenuates the pulsation by absorbing and releasing the hydraulic oil, making the system work more smoothly; in the hydraulic system, the sudden closing of the valve or the load change will generate impact pressure, causing damage to the equipment and pipelines. The Bladder Accumulator can absorb these impact pressures, protect the hydraulic components from damage, and reduce vibration and noise.
In a closed hydraulic system, changes in temperature and pressure will cause volume changes in the hydraulic oil. The Bladder Accumulator can automatically compensate for the volume changes caused by leakage or thermal expansion to maintain the stability of the system pressure.
The storage and release of energy is achieved through the elastic deformation of the airbag, which is highly efficient and responsive; the airbag material is corrosion-resistant, wear-resistant, and has good sealing performance, ensuring the long-term stable operation of the accumulator; the structure is simple and maintenance is convenient, reducing maintenance costs and downtime; the pressure vessel is made of high-strength materials and is equipped with protective devices such as safety valves to ensure safety and reliability under high-pressure environments.
