油管试压阀的设计与分析
摘要：
本课题油管试压装置设计。该产品应用于海上油田勘探和开采油田打井的快速钻井技术中。设计在原有试压装置的基础上，进行一些技术上的改进，通过机械电气控制将机械、液压、电气等技术融合在一起，使新装置在钻井效率、降低成本、简化工艺等方面有很好的发展，使其更具自动化和人性化。在这里，主要进行的是机械和电气控制系统的设计。
关键词：螺纹、套管、试压阀
Abstract:
The question for discuss—— the design of a equipment for the screw bushing’s pressurization and trial pressure, is a program of technique alteration in Hezhong corporation of south sea. The screw bushing which is mainly applied in the exploitation of flat roof on the sea, is a new product of this corporation in 2001. Based on the equipment which is now in use, the design make some technique alterations. It melt mechanism、fluid drive and electric in a pot with the help of mechanical and electric control. As a result, the new equipment is more automatic and is full of humanism than before. In here, the main tasks are the design of mechanism and electric control system.
Key words: screw、bushing、trial pressure 、mechatronics、automatization
第一章 系统方案的拟定.
1,螺纹套管的夹紧机构仍采用合众近海建设公司的作业现场的相同。虽然操作上有点不方便，但从经济上考虑，从产量方面考虑,从夹紧的可靠性考虑，采用现场设备，真正做到最大可能地利用原有设备。
2,拧紧机构采用液压马达带动旋转拨盘拨动螺纹堵头，将螺纹堵头旋进套管.采用的液压马达的扭矩很大，可达到23000Nm拧紧力,动力很大，能达到螺纹套管所要承受的扭矩负载，省去了一个庞大的传动系统,使机构简单紧凑。
3,因螺纹套管两头都要安装堵头，为节省时间，提高工作效率，堵头的旋进采用两边同时进行，即两边运动机构除旋转堵头不同外(一个为内螺纹,一个为外螺纹)，其余部分均可做的相同,从工艺方面考虑，不用采用两套不同的工艺，在制造时，应使两边的零部件具有互换性，从而简化工艺,提高系统的性价比。
4，系统的拧紧部份的传动链如下：电动机----液压泵-----液压马达-----联轴器-----旋转拨盘-----堵头。
5，整个系统的控制采用电气控制。
6，在此基础上，拟画螺纹套管试压装置原理图.
