Embodiment Construction
[0032] The strain strengthening system of the present invention includes a current water inlet device, a booster device, a hydraulic power device, a cooling device and a measurement control device. The pressure medium of the system is water, and the supercharger 7 adopts oil-displacing water technology, and the power source is hydraulic oil. The system flow is shown in Figure 1.
[0033] First, the compressed water source is provided through the water inlet device, and the impurities and particles in the water are removed through the filter 2, so as to prevent damage to the supercharger 7 and hydraulic components and improve the service life of the system. The filtered pressure medium water is boosted and output by the water inlet pump 4 to provide water source for the supercharger 7 . The water inlet pump 4 is a centrifugal pump. When the output pressure reaches the rated pressure, although the water inlet pump 4 is working, there is no flow output. For example, the output f...

The invention provides a container strain strengthening system, which comprises a water inlet device, a pressure device, a hydraulic power unit, a cooling device and a measurement and control device, wherein the measurement and control device is used for controlling the operations of the water inlet device, the pressure device and the hydraulic power unit. The low-temperature container strain strengthening system can make the strain strengthening processing technique of an austenitic stainless steel low-temperature container not depend on experience and manual control of the test pressure, thereby the labor intensity is greatly reduced and the machining precision and the machining efficiency are improved. Moreover, the invention also provides the austenitic stainless steel low-temperature container prepared by the container strain strengthening system.
Description
technical field [0001] The invention relates to the field of design and manufacture of low-temperature pressure vessels, in particular to a strain strengthening system for low-temperature vessels and an austenitic stainless steel low-temperature vessel produced by using the system. Background technique [0002] The cryogenic containers used to store and transport liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas and other cryogenic media have a double-layer structure, and the inner container is used to store cryogenic media. Due to the low temperature of more than minus 100 degrees, the inner container is made of austenitic stainless steel. And the inner container has to bear a certain pressure, and the material thickness is relatively large. For the design and manufacture of austenitic stainless steel pressure vessels, the domestic standards are based on GB150 "Steel Pressure Vessels". Compared with similar international advanced products, the materials ...
