A method for manufacturing a chemical pressure vessel body

Abstract

The invention relates to a method for manufacturing a tank body of a chemical pressure vessel, comprising a mounting plate, a position adjusting device, a detection device, two locking devices and two centering devices, the upper end of the mounting plate is equipped with a position adjusting device, the position adjusting device The upper end is equipped with a monitoring device, the lower end of the position adjustment device is symmetrically installed with a locking device, and the inner side of the locking device is provided with a self-aligning device. The method for manufacturing a chemical pressure vessel tank body provided by the present invention can solve the problem of fixing and splicing the chemical pressure vessel first when manually manufacturing the chemical pressure vessel, and then welding it. The production process is cumbersome and the existing chemical pressure vessel manufacturing equipment first fixes and welds the chemical pressure vessel, and then inspects it after welding. The process of inspection after welding will easily lead to inconsistent concentricity of the manufactured chemical pressure vessel Accurate, it needs to be fixed and so on.

Description

Technical field [0001] The present invention relates to the manufacture of chemical containers, and is specifically a method for producing a chemical pressure vessel can. Background technique [0002] The pressure vessel is a closed container capable of withstanding pressure. The use of pressure vessels is extremely wide, and it has important status and role in many departments and scientific research in industrial, civilian, military. Among them, the most used in the chemical industry and the petrochemical industry. Pressure vessels in chemical and petrochemical leadership, mainly used for heat transfer, mass transfer, reaction, etc., as well as storage, transportation, gas or liquefied gas; there is also a wide range of applications in other industrial and civilian sectors, such as air compressor. Auxiliary machine (cooler, buffer, oil water separator, air storage tank, evaporator, liquid coolant storage tank, etc.) of various special compressors and refrigerant compressors. ...

AI Technical Summary

Problems solved by technology

[0004] (1) When chemical pressure vessels are manufactured by manual production, the chemical pressure vessels are usually fixed and spliced ​​manually first, and then the fixed and spliced ​​chemical pressure vessels are welded. After the welding is completed, the concentricity is tested. The single splicing, welding and testing process of pressure vessels is cumbersome, which reduces the production efficiency of chemical pressure vessels;

[0005] (2) When the existing chemical pressure vessel manufacturing equipment manufactures chemical pressure vessels, the existing chemical pressure vessel manufacturing equipment usually fixes and splices the chemical pressure vessels first, and then directly welds the fixed and spliced ​​chemical pressure vessels, and the welding is completed Then inspect it. The process of inspection after welding will easily lead to low concentricity accuracy of the finished chemical pressure vessel, which needs to be repaired, thereby reducing the production efficiency of chemical pressure vessels.
