Description

Technical Field

[0001] The utility model relates to the technical field of accumulators, in particular to a diaphragm accumulator with adjustable volume. Background Art

[0002] The accumulator is an energy storage device in the hydraulic and pneumatic system. It converts the energy in the system into compression energy or potential energy and stores it at the appropriate time. When the system needs it, it converts the compression energy or potential energy into hydraulic or air pressure energy and releases it to replenish the system. When the system pressure increases instantly, it can absorb this part of the energy to ensure the normal pressure of the entire system. Hydraulic oil is an incompressible liquid, so it is impossible to accumulate pressure energy using hydraulic oil. It is necessary to rely on other media to convert and accumulate pressure energy. For example, the diaphragm-type gas-filled accumulator developed using the compressible properties of gas is a device for accumulating hydraulic oil.
