液下泵新型导轴承的研究

Study on the Stuffing PTFE of Wet Pit pump

通过对填充聚四氟乙烯导轴承的研究,得出了轴径与导轴承壁厚、运转间隙、最小冷却水量之间的关系曲线,以及填充聚四氟乙烯导轴承的设计方法,验证了采用此方法设计出的导轴承,具有较长的使用寿命。

With the studies about the stuffing PTFE, the variable curves between the shaft diameter andthe wall thickness of guiding bearing, the running clearance and the minimum of cooling water are obtainedas well as the design method of stuffing PTFE. It’s proved that the life of guiding bearing is rather longerdesigned according to the method.
