常规的抽油机主要是以基杆、游梁、曲柄以及连杆所组成的机构,而双驴头抽油机则是改进了常规四连杆机构抽油机的关键性技术,使之成为变参数的四杆机构抽油机,不仅冲程长、动载荷小、启动速度快、工作起来相对稳定,并且节能效果非常好,与同型号常规游梁式抽油机相比,在能源方面的消耗能够降低20%到30%左右。但是,双驴头抽油机现场使用过程中游梁断裂、支架晃动等方面的问题时常出现。因此,需要对双驴头抽油机主要部件的受力情况进行仔细的分析,在此基础上对后驴头和游梁之间相互联结的部分重新设计,之后根据各部件存在的问题采取有针对性的措施,从而有效的解决双驴头抽油机现场使用中出现的各种问题。
The conventional pumping unit is mainly composed of a base rod, a beam, a crank and a connecting rod, and the double donkey-head oil pumping unit is a key technique that improves the conventional four-bar mechanism pumping unit and makes it a Variable parameters of the four-rod pumping unit, not only the long stroke, dynamic load is small, fast start-up, work relatively stable, and energy-saving effect is very good, compared with the same type of conventional beam pumping unit, in terms of energy Consumption can be reduced by 20% to 30%. However, double donkeyhead pumping unit in the field of using beam breakage, scaffolding and other issues often appear. Therefore, it is necessary to carefully analyze the stress of the main components of Shuangtoutou pumping unit. Based on this, the reconnected parts of the post-donkey head and the hanger are redesigned. Afterwards, according to the existing problems of each component, Targeted measures, which effectively solve the dual donkey head pumping station in the field of use of various problems.
