对密封环齿面角度为３０°、４５°、６０°的六组试件进行了转速对密封耐压能力影响的实验研究．实验结果表明，对于每边轴套磁极上具有一道密封环的结构，在零转速时，可提供１６０～１８５ｋＰａ的耐压能力；在旋转轴圆周速度为２７ｍ／ｓ时，可提供１２０～１５０ｋＰａ的耐压能力．在齿面角度为３０°、旋转轴圆周速度为４２ｍ／ｓ时，可提供９０ｋＰａ的耐压能力．三种齿面角度的铁磁流体密封试件相比较，６０°时的静、动密封的耐压能力最高．并且分析了旋转轴动密封耐压能力随着转速的增加而下降的原因
The experimental study on the effect of rotational speed on the seal withstanding pressure was carried out on the six groups of specimens whose seal ring flank angles were 30 °, 45 ° and 60 °. The experimental results show that the structure with a sealing ring on the pole of each sleeve can provide a pressure resistance of 160 ~ 185kPa at zero speed and 120 ~ 150kPa at a rotational speed of 27m / s Pressure capacity. When the tooth flank angle is 30 ° and the peripheral speed of the rotating shaft is 42 m / s, the pressure resistance of 90 kPa can be provided. Compared with the ferromagnetic fluid seal specimens with three flank angles, the static and dynamic seals at 60 ° have the highest pressure capacity. The reasons why the pressure resistance of the rotating shaft is decreased with the increase of the rotating speed are analyzed
