【摘要】：以往大型、中型绞车通常情况下主要都是有传动轴,猫头轴,中间轴和滚筒轴四根轴。在如今这个时代,石油钻机绞车的迅速发展,改变了以往基本型结构的制约出现大量新型绞车。但大多数绞车的冷却系统比较落后,冷却效率低,不能符合现场施工的要求,所以设计和制造新型的钻机绞车刹车冷却系统很有发展前景。本文论述了钻机绞车在石油钻机绞车上的国内外发展状况和内容,分析了课题研究的内容和意义。其次,针对7000米钻机绞车特性要求,对其控制策略进行了研究和探讨,进而决定采用相应的控制方式。再次,分析了7000米钻机绞车的自身结构、工作原理、绞车的工作特点、绞车的分类以及绞车的设计准则,接着,根据以上准则联系绞车自身的设计准则,提出绞车自身各部分及其刹车冷却系统的设计方案,并进行相应的理论设计计算。利用数值模拟方法对7000米钻机绞车刹车冷却系统进行数值模拟,采用雷诺时均方法,利用标准k-ε湍流模型,并结合标准壁面函数,对本文设计的绞车刹车冷却系统的冷却性能的进行模拟测试,最终得到结论本文设计的7000米钻机绞车刹车冷却系统,冷却性能良好,可以符合现场的作业需求。
[Abstract]:In the past, large and medium winch usually had four axes: drive shaft, cat head shaft, intermediate shaft and roller shaft. In this era, the rapid development of oil rig winch has changed the constraints of the previous basic structure, a large number of new winch. However, the cooling system of most winches is relatively backward and the cooling efficiency is low, which can not meet the requirements of field construction, so the design and manufacture of a new type of cooling system for drilling winch brake is very promising. This paper discusses the development and content of drilling winch at home and abroad, and analyzes the content and significance of the research. Secondly, according to the characteristic requirement of 7000 meter drill winch, the control strategy is studied and discussed, and the corresponding control mode is decided. Thirdly, the structure, working principle, working characteristics, classification of winch and design criterion of winch are analyzed. Then, according to the above criteria, the design criterion of winch itself is connected. The design scheme of the winch itself and its brake cooling system is put forward, and the corresponding theoretical design and calculation are carried out. The braking cooling system of 7000 meter rig winch was simulated by numerical simulation method. The Reynolds time average method, the standard k- 蔚 turbulence model and the standard wall function were used. The cooling performance of the winch brake cooling system designed in this paper is simulated and tested. Finally, the conclusion is drawn that the cooling performance of the brake cooling system of the 7000 meter drill winch designed in this paper is good and can meet the requirements of the field operation.
