摘要
根据海底管道封堵器直角拐弯推进器的设计要求,对管道封堵器单向直角拐弯送进的方法、送进接头的通过性和居中性问题进行了深入研究。通过结构设计实现了管道封堵器的单向直角拐弯送进,采用特殊设计的导向座和对送进接头进行约束分析,确保封堵器和送进接头在封堵器送进过程中能够满足通过性要求;并因采用特殊设计的支撑导轮实现了接头在封堵器送进过程中的居中性要求。
According to the design demand of the right angle turning propeller of the subsea pipeline plugging device,the in-depth study of unidirectional right angle turning propelling method,the passing and centralizing of propelling sub is carried out.The unidirectional right angle turning propelling of the pipeline plugging device is realized by structural design.The passing demand of plugging device and propelling sub is ensured by using special guiding seat and performing the constraint analysis of propelling sub.In addition,the centralizing demand of the sub during the propelling of the plugging device is also realized by using special supporting guiding wheel.
