Case study

2024-11-15

In a hydraulic circuit with multiple accumulators in parallel, if one bladder ruptures, will the volume of the other accumulators change?

Accumulators are interesting components in hydraulic systems, similar to capacitors in circuits and springs in mechanics. They are important energy storage components and can be used in hybrid power systems, shock absorbers, pressure stabilization systems (sometimes flow stabilization), and the simulation of impact through instantaneous energy release, among other clever applications.

Are pouch-type energy storage devices suitable for use with series-connected cylinders or cylinder groups?

1. Bellows typically have a shorter lifespan (compared to piston-type) and there is significant quality variation between brands; 2. Many factors contribute to shortened bellows lifespan and rupture, including inherent quality variations in the bellows themselves, improper operation during bellows assembly (such as failure to lubricate with fluid beforehand), improper pre-inflation procedures (such as failure to inflate slowly), pre-inflation pressure calculation errors, oil port flow rates approaching or exceeding 7 m/s, single reciprocation times approaching or less than 10 seconds when used for energy storage, bellows colliding with the check valve during operation, large temperature fluctuations (including large seasonal temperature differences), prolonged lateral vibration and shaking, fluid corrosion, inertial impact from small solid impurities in the medium, etc.;

How to use the accumulator inflation valve?

When using the hydraulic station for the first time, it needs to be inflated. The nitrogen pressure in the accumulator must fluctuate within a certain range. The inflation pressure is generally between 1/3 and 3/4 of the working pressure of the oil cylinder. In this way, the inflation pressure of the mill accumulator is 4-5 MPa. If the pressure is too high or too low, it will not be effective.
