Advantages of capsule accumulator

Advantages of skin capacitor:

Small inertia, sensitive reaction, suitable for pulse elimination.Is it oil?Gas, oil?Gases do not mix (if not break);

Easy maintenance, less ancillary equipment, easy installation, easy to inflate.

Disadvantages: the service life of leather bags usually cannot reach the service life of (piston type) seal, and the quality of leather bags of different brands is quite different;

There are many factors that lead to the rupture of the leather bag, including the difference in the quality life of the leather bag itself, improper operation of the leather bag assembly, improper operation of the spare air, calculation error of the prepressure, large temperature variation in xiangshan hydraulic accumulator factory (large seasonal temperature difference), long-term transverse vibration and shaking, fluid corrosion;Inertia impact of small solid impurities in the medium, etc.

When the skin ruptures, the accumulator may suddenly fail.A large amount of gas mixing in an instant or a short time may result in a system accident.

Skin bags should not be made too large, or the life of skin bags will be affected. ASME standard is generally 60 liters at most, and most of Europe is 50 liters.

The working pressure is not too high, the domestic (3 times or smaller safety factor) is generally 31.5 Mpa, the expansion bag accumulator (4 times safety factor) is 51.8 Mpa;

Due to the design and processing quality, when yuyao hydraulic accumulator factory released oil quickly, the fungus valve of many brands of capsule accumulator closed ahead of time, resulting in a sudden partial fault of the accumulator.

The leather bag is made of rubber, and its strength is not high, so it cannot withstand great pressure fluctuation (note the compression ratio of the leather bag).Therefore, the skin accumulator is not suitable for series cylinder or cylinder group.
