Germany hydac The main types of accumulators are spring and inflatable. The function of accumulator (1) short term massive oil supply (2) system maintains 3. Emergency energy (4) relieved the impact pressure (5). Absorbing the pulsating pressure accumulator function is mainly divided into four categories: storing energy, absorbing hydraulic shock, eliminating pulse and recovering energy.

The first type: energy storage. This kind of function can be subdivided into: (1) auxiliary power source, reducing installed capacity; (2) compensating leakage; (3) compensating for thermal expansion; (4) making an emergency power source; and (5) forming a constant pressure oil source.

The second type: absorb hydraulic shock. The sudden change of the reversing valve and the sudden stop of the movement of the executive element will produce a pressure shock in the hydraulic system, causing the system pressure to rise rapidly in a short time, causing damage to the instruments, components and sealing devices, and causing vibration and noise. In order to ensure the absorption effect, the accumulator should be placed near the impact point, so accumulators can be well absorbed and buffered before the shock source is installed in the control valve or hydraulic cylinder.

The third category: eliminate pulse and reduce noise. For a hydraulic system using plunger pump and its number of plungers is less, the vibration of the system is caused by the periodic variation of pump flow. The accumulator can absorb the energy of fluctuating pressure and flow in a cycle of flow pulsation. Part of the oil with instantaneous flow rate higher than the average flow is absorbed by the accumulator, which is supplemented by the accumulator below the average flow volume, which absorbs the energy in the pulsation, reduces the pulsation, and reduces the damage to sensitive instruments and equipment.

The fourth category: energy recovery. Energy recovery by accumulator is a field that is studied more. Energy recovery can improve energy efficiency and is an important way to save energy. Because the accumulator can temporarily store energy, it can be used to recover various functions and position potential energy. The main researches in this area are as follows: 1. Recovering vehicle braking energy; second, recovering the potential energy of the mechanism arm of the engineering machinery; 3. Recovering the braking energy of the hydraulic excavator; 4. Recovering the gravity potential energy of the oil workover rig and the drill pipe; and recovering the downward gravity potential energy of the elevator. Germany hydac
