- 为了提高LNG装车橇装车环节的安全性,增强操作人员的安全意识,基于批量控制仪装车平台,利用自锁紧插销和行程开关等设备,运用DCS控制系统的信号检测技术对LNG装车橇鹤管归位锁紧装置进行总体设计及工程应用。该装置能够通过DCS控制系统的信号检测技术,实现对LNG装车橇鹤管归位锁紧装置的信号检测与反馈。应用结果表明:通过对LNG装车橇鹤管归位锁紧装置的设计,能够实现对鹤管归位状态的信号检测与反馈,操作流程得到了有效控制,大大减少了误操作和其它因素的干扰,有助于保障操作人员的安全。该装置在LNG装车站得到了安全应用,充分证明了该装置的安全性和实用性。本设计简单实用,满足防爆安全性能的相关要求,有助于推动操作流程的安全设计,降低因装车后鹤管不归位及其它因素带来的风险,提高LNG罐装现场运行的安全性,防止天然气泄漏。
In order to improve the safety of loading operation of skid-mounted LNG loading facility and strengthen the safety awareness of operating personnel, with the help of batch control instrument loading platform, used are such devices as automatic locking bolt and travel switch and applied is the signal detection technique of DCS control system to design a homing locking device for crane arm of skid-mounted LNG loading facility and applied is the device in actual loading operation. Actual application results show that the new homing locking device can implement signal detection and feedback of crane arm homing state, operation process can be effectively controlled, misoperation and interference of other factors can be reduced greatly, which can help to protect the safety of operating personnel. Effective application of this device at LNG loading stations has fully demonstrated its safety and practicability.
