Embodiment 1
[0183] In the embodiment of the present application, an aluminum alloy liner 100 for a high-pressure gas cylinder with a diameter of 420 mm, a length of 2.5 m, and a wall thickness of 4 mm is manufactured through the above-mentioned method for manufacturing an ultra-high pressure full-winding gas cylinder with an aluminum alloy liner with a one-end back cover. Among them, the rated pressure of the high-pressure gas cylinder is required to be 35Mpa, and the specific steps are as follows:
[0184] Step S1, integral reverse extrusion molding of the blank with the back cover;
[0185] The step S1: using the heating reverse extrusion process combined with the turning and boring process to prepare a seamless pipe consisting of a back cover and a straight section with one end open; specifically, the steps are as follows:
[0186] Aluminum ingot heating, preheating the aluminum ingot to be extruded to 200-400°C;
[0187] Mold heating, preheating both the extrusion outer mold and the ...

Abstract
The invention provides an ultrahigh-pressure full-winding gas cylinder with an aluminum alloy inner container sealed at one end and a manufacturing method of the ultrahigh-pressure full-winding gas cylinder. The ultrahigh-pressure full-winding gas cylinder with the aluminum alloy inner container sealed at one end comprises the aluminum alloy inner container, a composite material reinforcing layer and an external protection layer; the aluminum alloy inner container is of an integrated seamless structure with one end sealed and the other end closed to form an end socket and a bottle opening, the end socket and the sealed bottom are located at the two ends of a straight cylinder section correspondingly, and the bottle opening is located on the end socket; the length of the aluminum alloy inner container is smaller than 5 meters, the nominal outer diameter of the straight cylinder section is phi 406-phi 850 mm, and the rated pressure of the ultrahigh pressure gas cylinder is 30-90 Mpa; the outer side of the aluminum alloy inner container is coated with the composite material reinforcing layer, and the composite material reinforcing layer is formed by winding carbon fibers in a spiral and annular combined winding mode and curing the carbon fibers through resin; and the outer protection layer is coated on the outer side of the composite material reinforcing layer, and is formed by winding glass fibers in a spiral and annular combined winding mode and curing the glass fibers by using resin.
Description
technical field [0001] The present application relates to the technical field of high-pressure containers, in particular to an ultra-high pressure full-wound gas cylinder with an aluminum alloy liner sealed at one end and a manufacturing method thereof. Background technique [0002] With the rapid development and industrialization of hydrogen fuel cells and electric vehicles, the research and construction of hydrogen source technology and hydrogen energy infrastructure have attracted great attention from developed countries. Safe and economical hydrogen storage and transportation technology is the key to promote the practical and industrialization of hydrogen energy utilization. High-pressure hydrogen storage using ultra-high pressure gas cylinders with a pressure of 35-70MPa is the most commonly used and most direct way of hydrogen storage. High-pressure hydrogen storage can be used at room temperature, and the hydrogen can be released directly through the adjustment of th...
