摘　　要：为了对新研制的井下螺旋轴流式气液混输泵样机进行试验研究,建立了1套气液混输泵试验台架。整个试验台架由泵级部分、吸入部分、排出部分和数据采集部分组成。在给出试验样机基本结构和试验原理的基础上,阐述了样机的试验方法和步骤,通过试验得出样机在设计转速下输送纯水和含气体积分数为40%气液混输工况下的外特性曲线。前期的试验研究验证了新建立的井下气液混输泵试验台架和研制的井下螺旋轴流式气液混输泵样机均满足设计要求,同时也为下一步完善设计和今后样机的试验研究提供了依据。In order to carry out the experimental study on the newly developed downhole helical-axial gas-liquid pump, a new set of test stand for downhole gas-liquid pump is designed and established. The whole test stand is mainly made of pump stage part, intake part, discharge part and data acquisition part. On the basis of the fundamental structure and test principle of the test prototype, the test method and process are discussed. The exterior characteristic curve of the prototype is obtained through the test when transporting the pure water and the gas-liquid fluid with 40% of gas at the designed rotating speed. The test results at the early stage indicate that both the newly-established test stand and the developed downhole helical-axial gas-liquid pump can meet the design demand.
