为解决传统深水海底管道的清管问题,结合海底管道的清管原理,设计了一种新型的水下清管器发射装置,从而有效地避免了平台发射清管器所带来的清管器回收和管道停输等问题。对水下清管器发射装置进行了详细的结构设计,主要包括连接器、保护框架、发射主体结构、上部开合机构和阀门控制系统;介绍了水下发射清管的作业流程,论述了该装置相对于传统清管器发射装置具有的诸多优势;最后对发射装置的储球筒和卡爪连接法兰这两个关键部件进行了数值分析,其结果显示满足设计要求。该装置为深水清管作业提供了一种新的行之有效的方法。
In order to solve the pigging problem of traditional deep-sea submarine pipeline, a new underwater pig launching device is designed according to the pigging principle of submarine pipelines, so as to effectively avoid pigging pigs brought by platform launching pigs Recycling and pipeline shutdown and other issues. The detailed design of underwater launcher launcher is made, including the connector, the protective frame, the main structure of the launcher, the upper opening and closing mechanism and the valve control system. The working procedure of underwater launcher pigging is introduced. Compared with the traditional pig launcher, the device has many advantages. Finally, the numerical analysis of two key components of the launcher cylinder and the claw connecting flange has been shown to meet the design requirements. The device provides a new and effective method for deepwater pigging operations.
