Preparation of this project. Objective to study how to distill nitrogen cooling process of ultra Analysis of causes of leakage of cylinder cover, offering solutions.The operation is We study the theory related to leakage of cylinder cover, including
.The theory of monitoring compared with screw lid opening cylinder, screw design theory analysis of buckling of the tank. Graph theory the relationship between screw with gasket sheet. The theory of tension screw used in the bowl. From the book, both domestic and abroad.And the experienced when the theory according to, we analyze equipment parts. Each piece according to the theory, and the data is a form of computation the
.Compared with the real parts used in the experiment. To find the corresponding data used to analyze the cause of the leakage of the tank. The problem of leakage in each case.Due to excessive force screw gasket stress value can bear. The gasket is twisted deformation makes the cylinder cover not closed the leak. And caused by screw used in the bowl is small. The force from the bowl is not enough.The gasket sheet and cylinder cover at the bend body, gap. When the pressure inside the tank, there are the more the force that is used to press the lid tank. The leakage screw
.After that, the proposed solutions and design new pail lid: use a flange surface lift. Increase the thickness of the cylinder cover more than 7.24 mm, change size screws is M12 by force used in the competition, must not exceed 23900 Newton were สกรูอย่างน้อย 35. To prevent leakage of cylinder cover in the production process of liquid nitrogen. And it can be used in making further development project in the future!
