卧式高压釜快开装置设计

Design of quick-opening device of high pressure autoclave

设计了由快开机构、液压传动和电气控制系统组成的新型高压釜快开装置.首先,针对传统快开机构在结构设计上的缺陷,快开装置采用了新型结构设计方案,提高其可靠性和可维修性;其次,选用液压传动系统作为快开装置的动力源,并进行了液压系统设计与液压元件的选型;最后,设计了电气控制系统,采用可编程控制器控制以提高快开装置自动化水平,并制定了快开装置的工作流程,进行了程序的编写及调试.结果表明,该新型快开装置不仅能够平稳高效地实现高压釜端盖的开闭,易于后期维修保养,而且能较方便地实现远程控制,避免其操作人员受到安全威胁.

A new type of quick-opening device of high pressure autoclave which consists of the mechanism,the hydraulic transmission system and the electrical control system was designed.Firstly,for the imperfection of the structure design of the old ones,a new structure designing scheme was adopted to improve the reliability and maintainability.Secondly,hydraulic transmission was used as the power source of the quick opening device,and the design of hydraulic system and the selection of hydraulic components were accomplished.Then,the electrical control system controlled by programmable logic controller was designed to improve the degree of automation.Finally,the workflow of the quick-open ing device was established and the program was written and debugged.Results show that this new type of quick opening device can efficiently and smoothly realize the opening and closing of the end cover,and is easy to be maintained and repaired at later stage,moreover it can conveniently realize the remote control to ensure the life safety of the operators.
