Description

Technical Field

[0001] The utility model relates to the technical field of accumulators, in particular to an adjustable accumulator. 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 right 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.

[0003] The utility model patent with publication (announcement) number: CN217381058U solves the problem that the existing accumulator has no compensation function and is prone to air leakage after long-term use, resulting in a decrease in internal air pressure and a weakened energy storage effect, requiring re-inflation, which is time-consuming and labor-intensive. The utility model patent adopts a rotating screw to control the movement of the air-tight part in the compensation cylinder. When the air-tight part compresses the gas in the compensation cylinder and moves it toward the upper shell side, the air pressure in the accumulator can be increased. It can play a compensatory role when air leakage occurs for a long time, ensure the energy storage effect, and extend the service life of the accumulator. However, in actual use, the rotating screw is not locked. When the operator accidentally touches the rotating screw, the air-tight part will move, thereby changing the air pressure in the upper shell, making it impossible to perform accurate compensation. In addition, the device cannot accurately reflect the air pressure in the outer shell, which makes it inconvenient for the operator to accurately compensate for the air pressure in the upper shell.
