The invention discloses a connecting device for hydraulic energy accumulators. The connecting device comprises a horizontally-arranged energy accumulating pipe. One end of the energy accumulating pipe is sealed, and the other end of the energy accumulating pipe is provided with a pipeline flange disc connected with a hydraulic pipeline. The diameter of the energy accumulating pipe is larger than that of the hydraulic pipeline. The lower portion of the energy accumulating pipe is connected with a fixed base through supporting plates. The upper portion of a middle section of the energy accumulating pipe communicates with at least two vertical pipes. The top end of each vertical pipe is connected with a mushroom valve of the corresponding hydraulic energy accumulator. The hydraulic energy accumulators are connected to the upper portion of the middle section of the horizontally-arranged energy accumulating pipe. During energy accumulating, the impact of hydraulic oil enters the energy accumulators through the energy accumulating pipe, the hydraulic impact is reduced, vibration at the joints of the mushroom valves of the hydraulic energy accumulators is reduced, the thread loosening possibility is decreased, and a guarantee is provided for safe and continuous production.
Description
technical field [0001] The invention relates to the field of hydraulic machinery, in particular to a hydraulic accumulator connection device. Background technique [0002] The hydraulic accumulator is an energy storage device, which can store the hydraulic pressure in a pressure-resistant container, and release it to re-supply the system when the system needs it. When the system pressure increases instantaneously, it can absorb this part energy to ensure the normal pressure of the entire system. [0003] The hydraulic accumulator is an important device to maintain the pressure of the grinding roller and reduce the impact load of the hydraulic system in the equipment that is gradually pressurized by the action of the hydraulic cylinder, especially in the large-scale powder processing equipment, such as the hydraulic cylinder system of the vertical mill used in the cement processing industry. , a hydraulic cylinder is equipped with 2-4 hydraulic accumulators, and a powder pro...
