Influence factor of pressure's variety is the ratio k|- of the total area of balance hole of impeller and the area of back joint ring's clearance d_1. If k≥2, the variety of pressure P in balance cavity is smoothness.
以3BA-6单级单吸离心泵为研究对象,通过对平衡腔内压力的定量分析得出:平衡腔内压力p的变化是实现浮动叶轮自动调节的关键技术之一,影响压力变化的主要因素是叶轮平衡孔总面积与后密封环间隙d_1的面积的比值k;当k≥2时,平衡腔内压力p变化平坦。
