蒸压釜快开门联锁装置强制检验的必要性

Necessity of Mandatory Inspection of Door Interlock Device in Autoclave

通过对在用蒸压釜齿啮式结构的快开门联锁装置(以下简称联锁装置)的技术现状和安全管理方面存在的问题进行研究分析,明确指出蒸压釜设计技术文件必须提供开启安全余压、啮合齿最小安全接触面积和最低啮合度计算资料和联锁装置安装试验技术要求,使制造、安装、使用、管理、检验、修理等环节中安全技术得到有效可靠运转;通过对联锁装置中本质安全认识和理解,进一步剖析泄气槽与密封锁紧机构原理及其本质安全作用,只有大力推行设备本质安全设计,才真正有效地控制得到当设备系统在发生故障或者操作者误操作、误判断时,不会造成安全事故的发生;只有对联锁装置实行强制检验,设备的安全运行才得到更有效的保障。

By analyzing the problems of current technical situation and security management of the toothlocked autoclave door interlock hereinafter referred to as interlocking device, it will point out explicitly that the design technical documents of reaction caldron in the aero concrete production must provide the pressure of open security, meshing tooth minimum safety contact area and the minimum degree of meshing calculation data and interlocking device installation test technical requirements. It can make the safety technology effective and reliable operation during manufacturing, installation, using, management, inspection and repairing. Through the intrinsically safe understanding of interlocking device, analyzing the principles of frustrated groove and seal lock mechanism and its effect on the intrinsically safe deeply, it is found that the design of intrinsically safe should be carried out to effectiveky control and avoid the safety accidents happening when the equipment system is failure, operator error operation or false judgment. Only mandatory inspection of interlock is implemented, the safe of equipment operation can be guarantee effectively.
