| 摘 要： | 在3BA-6型单级单吸离心泵上,通过更换不同直径平衡孔叶轮的试验,测量了叶轮后密封出口压力、泵进口压力,得出了平衡腔内液体压力、泵进口压力与泵扬程的试验曲线。据此计算得到了平衡孔液体泄漏量特性曲线。在设计工况下,比较分析了当平衡孔直径不同时平衡孔液体泄漏量理论曲线与试验曲线。实测泵轴向力曲线表明依据平衡孔泄漏量特性曲线计算得到的轴向力曲线,可以满足工程计算需要。

| Abstract: | The test by changing different diameters of balanced hole in the 3BA-6 single grade single suction pump was made.The pressure of outlet of impeller rear sealing and the pressure of inlet in pump were measured.The test curves of the liquid pressure in balance cavum and the pump head,and the pressure of import of the pump and the pump head were both obtained.Thus the fluid leakage characteristic curves of balance cavum were obtained.The theoretical curves and the test curves of fluid leakage in balance cavum at the different diameters were compared and analyzed in design condition.After measured the axial force curves of pump,the result showed that axial force curves which obtained by calculating based on the fluid leakage characteristic curves of balance cavum could meet the engineering calculation need. |
