1. Product Overview
Diaphragm accumulator is an energy storage device in hydraulic and pneumatic systems. Compared with similar products, the biggest feature of diaphragm accumulator is that it is easy to carry in weight, easy to install and promote, highly sensitive and effective, with a simple and easy to maintain structure, and has a significant effect on eliminating pulsation at low pressure. Therefore, it plays an important role in various industries. Diaphragm accumulator can generally be divided into two types: welded and threaded. The welded structure is simple and cost-effective; The threaded type can replace the diaphragm and improve the utilization rate of the accumulator.
2. Working principle
The main principle of diaphragm accumulator is to use Boyle's law, which states that the compressibility of gas is achieved through the compression of liquid for energy storage. At the beginning, the predetermined pressure gas is filled into the airtight isolation capsule in the accumulator, and the surrounding of the capsule is connected to the liquid and hydraulic circuit. The energy conversion method is as follows: when the pressure increases, the liquid compresses the gas, and the liquid enters the diaphragm accumulator to store energy; When the pressure drops, the compressed gas begins to expand, causing the liquid to flow towards the hydraulic circuit and release energy.

4. Structural dimensions
The main structure of a diaphragm accumulator is to tightly fasten two hemispheres and use a middle diaphragm to separate the gas and oil (usually nitrogen and oil) inside the hemispheres. Specifically, it is composed of a pressure resistant steel container, a diaphragm made of deformable flexible material (usually made of rubber), a closed seat, a closed seat, etc. The internal structure and external dimensions of the GXQ series diaphragm accumulator are shown in the following figure:

6. Precautions
① Before installation, it is necessary to check the surface for any damage and carefully read the user manual;
② During installation, it is important to pay attention to whether the nitrogen meter contains impurities;
③ After installation, it is necessary to debug the accumulator to see if there are any issues;
④ It should be noted that the backup airbag of the accumulator should be stored in a cool and dry place.
