A Vibration Buffer Mechanism for Accumulator

Abstract

The invention relates to the technical field of energy saving and environmental protection, and discloses a vibration buffer mechanism of an accumulator, which includes a housing, an air vent is opened in the middle of the upper end of the housing, and a liquid opening is opened in the middle of the lower end of the housing. A mushroom-shaped valve is movably installed on the lower end of the inner cavity of the housing, a first air bag is movably installed on the upper end of the inner cavity of the housing, and a second air bag is movably connected to the inner wall of the lower end of the inner cavity of the housing. In the present invention, the multi-bag energy storage mechanism is arranged so that the movable cylinder drives the ejector rod to move inwardly by filling the gas storage chamber with gas, so that the middle part of the second air bag is moved closer to the middle part of the inner cavity of the housing, so that by setting two The airbags cooperate with each other under the action of gas pressure, thereby slowing down the impact of the second airbag and the first airbag on the two due to mass difference, temperature change and gas pressure calculation error during normal operation, ensuring the working life of the accumulator.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to a vibration buffering mechanism of an accumulator. Background technique [0002] The accumulator is an energy storage device in the hydraulic 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 pressure. or air pressure and other energy, and resupply the system. When the instantaneous pressure of the system increases, it can absorb this part of the energy to ensure the normal pressure of the entire system. The type of accumulator is divided into airbag type, There are many kinds of spring type and diaphragm type. Among them, the airbag type accumulator has the advantages of small inertia, sensitive response, inflation and sealing, and easy installation and maintenanc...
