Embodiment 1

[0065] Such as figure 1 As shown, the embodiment discloses an accumulator with external gas supply source capsules with fixed lateral telescopic deformation at both ends to store energy and oil level control. The inner surface is smooth, which is beneficial to processing. The outer surfaces of the two open ends of the capsule 6 all have spherical blocks, and several annular spherical bumps are also provided on the inclined surface near the spherical blocks.

[0066] The spherical body round piece at the opening end of the capsule 6 at the air inlet end is pressed and embedded in the notch of the ventilation assembly 4; the diameter of the capsule 6 is about half of the inner diameter of the canister 5, and its two ends are made with thicker ports, gradually moving towards the middle at a certain distance Thinning is beneficial to realize lateral deformation energy storage and improve the use efficiency of the bladder accumulator; a sealing ring and a retaining ring 3 are insta...

Embodiment 2

[0069] Such as figure 2 As shown, this embodiment discloses a bladder-type accumulator with openings at both ends of the capsule with an external air supply source, a cushion pad, which can be stretched and deformed horizontally and vertically to store energy and has oil level control. 5 capsules 6 at both ends; the inner surface of the capsule 6 is smooth, which is beneficial to processing, and the outer surfaces of the two open ends of the capsule 6 all have spherical body circles, and several annular spherical protrusions are also provided on the inclined surface near the spherical body circles.

[0070] The spherical body round block at the opening end of the air inlet capsule 6 is pressed and embedded in the notch of the ventilation assembly 4; It is thin, which is beneficial to realize lateral deformation energy storage and improve the use efficiency of the bladder accumulator; a sealing ring and a retaining ring 3 are installed on the outer peripheral surface of the ve...

Embodiment 3

[0073] Such as image 3 As shown, one end of the capsule with an external air supply source disclosed in this embodiment is open and the other end is closed. The hemispherical capsule accumulator with buffer energy, horizontal and vertical telescopic deformation, energy storage and oil level control includes an air intake end. Open capsule 3-1, the bottom of the capsule 3-1 at the other end is closed semi-spherical, and its inner surface is smooth, which is beneficial to processing.

[0074]The spherical body round block at the opening end of the air inlet capsule 3-1 is pressed and embedded in the notch of the ventilation assembly 4; The distance is thinned toward the middle, which is conducive to the realization of lateral deformation energy storage, and improves the use efficiency of the bladder accumulator; the outer circumferential surface of the ventilation assembly 4 is equipped with a sealing ring and a retaining ring 3; The nut 2 compresses the ventilation assembly 4...

Abstract

The invention provides a bladder type energy accumulator which is of five structures and has an external air source and an oil level control function. The energy accumulator can horizontally stretch or retreat to deform to store energy, can allow a bladder to be taken out integrally for in-situ replacement, can horizontally or vertically deform to store energy, or has a pull-rod fixed-capacity/variable-capacity control function. According to the operating principle, energy storage is realized through horizontal deformation of the bladder or through main horizontal deformation and auxiliary vertical deformation. According to the structure of the bladder, the diameter of the bladder is half that of a cylinder, the two ends of the bladder are fixed and are open, or one end of the bladder is closed, and the bladder becomes thinner gradually from the two ends to the middle. Oil and gas are separated by the bladder, gas is guided into the bladder, oil is injected outside the bladder, energyconversion is achieved by means of gas pressure changes caused by alternate changes of the volume of oil and the volume of gas, and thus, the purposes of energy storage and release are realized. An automatic alarm device is arranged for oil shortages. Inlet oil can be magnetically filtered. The bladder type energy accumulator has the advantages that the structure is simple, the manufacturing costis lower, machining, manufacturing and maintenance are convenient, and responding is more sensitive; and intelligent control can be achieved, and the bladder type energy accumulator is suitable for alarge-capacity energy storage and closed-loop hydraulic balance system.

Description

technical field [0001] This final draft involves a variety of capsule accumulators with external air sources, which are used in pneumatic, hydraulic, mechanical and other transmissions, and belong to the field of pneumatic, hydraulic, electromechanical, gas-liquid balance and energy saving. Background technique [0002] At present, in various production fields, there are occasions where a large number of lifting loads move, and a large number of hydraulic transmission and control are used in the project. Previously, in order to control the fast, stable and precise positioning of the lifting motion of large inertia objects, engineers and technicians thought of many ways in hydraulic control, and achieved satisfactory results. However, due to the different characteristics of loads, task purposes, process requirements and controls in use in various industries and equipment, the potential energy of each movement is not widely used in hydraulic systems that include lifting or swi...
