摘　　要：以基于二级的双头短幅外摆线型螺杆泵为研究对象,对腔室内压力形成以及举升压力和排量等举升性能进行分析。结果表明:与双头短幅内摆线型螺杆泵相比,双头短幅外摆线型螺杆泵的举升压力和排量均降低30%左右;油田用双头短幅内摆线型螺杆泵可以有效提高工作效率,节省时间,而双头短幅外摆线型螺杆泵生产和检修成本低,适用于产量低的浅井。Taking two-stage double-thread short-amplitude internal cycloidal screw pump as the research object,the chamber pressure formation and lifting performance such as lifting pressure and displacement were analyzed.The results showed that,compared with the double-thread short-amplitude internal cycloidal screw pump,the lifting pressure and displacement of external cycloidal pump were reduced by about 30%.Therefore,the external cycloidal screw pump was more suitable for applications in the shallow wells with low production due to its low production and maintenance cost,while use of the internal cycloidal screw pump in oil field could improve work efficiency and save time effectively.
