Embodiment
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0024] Such as figure 1 As shown, a pressure-reducing hydraulic accumulator is characterized in that it includes a cylinder barrel 1, a cylinder piston 2, a cylinder head 7, an oil cylinder barrel 4, an oil cylinder piston 6 and an oil cylinder piston rod 5. The cylinder barrel 1 and the oil cylinder barrel 4 are fixed together by connecting bolts 3 . The oil cylinder piston 6 and the oil cylinder piston rod 5 are integrally formed. The oil cylinder piston rod 5 passes through the cylinder head 7 and connects with the cylinder piston 2. The cylinder piston 2 isolates the cylinder barrel 1 into a h...

The invention provides a pressurization and volume reduction hydraulic energy accumulator. The pressurization and volume reduction hydraulic energy accumulator comprises an air cylinder barrel, an air cylinder piston, a cylinder cover, an oil cylinder barrel, an oil cylinder piston and an oil cylinder piston rod, wherein the oil cylinder piston and the oil cylinder piston rod are integrally formed; the oil cylinder piston rod penetrates through the cylinder cover to be connected with the cylinder piston; the cylinder piston divides the cylinder into a high-pressure air cavity and a first oil cavity, the high-pressure air cavity is filled with high-pressure gas, the oil cylinder piston divides the oil cylinder barrel into an air cavity and a second oil cavity; an air inflation hole is formed in one end, far away from the cylinder cover, of the air cylinder barrel, one end, away from the cylinder cover, of the oil cylinder barrel is provided with an oil port, the oil port is connected with an external oil way, and an air outlet hole is formed in the side wall of one end, close to the cylinder cover, of the oil cylinder barrel, so that an atmospheric cavity communicates with the outside atmosphere. A central hole is formed in the middle of the oil cylinder piston rod and the oil cylinder piston, a radial hole is formed in the side wall of one end of the oil cylinder piston rod located in the first oil cavity, and the radial hole communicates with the central hole and the second oil cavity. According to the pressurizing and volume-reducing hydraulic energy accumulator, the energy storage density is improved by the double-oil-cavity oil storage separated by the two pistons, and the occupied space of the energy accumulator is reduced.
Description
technical field [0001] The invention relates to the field of hydraulic transmission and control, in particular to a pressure-increasing and volume-reducing hydraulic accumulator. Background technique [0002] A hydraulic accumulator is an energy storage device in a hydraulic pneumatic system. It converts the energy in the system into compression energy or potential energy at an appropriate time and stores it. When the system needs it, it converts the compression energy or potential energy into hydraulic or pneumatic energy and releases it to replenish the system. When the pressure of the system increases instantaneously, it can absorb this part of the energy to ensure the normal pressure of the whole system. [0003] Accumulators can be divided into heavy hammer type, spring type and gas loaded type according to the loading method. [0004] The hammer type accumulator has simple structure, stable pressure, large volume, bulky, large motion inertia, insensitive response, ea...
