| 摘 要： | 螺旋密封是一种非接触型动力密封。它利用轴在旋转时的摩擦力对加工在密封套上或轴套上的螺旋槽内液体供给能量,产生泵送作用,使槽内液体的压力增高,以平衡机内被密封介质的压降,促使液体不断返回高压端,从而阻止泄漏,螺旋密封又称为螺纹密封。

| Abstract: | Helix seal is a non contact dynamic seal. It use the friction which produced in the shaft rotation supply energy to the liquid of sealing sleeve or spiral slot on the sleeve, and produces pumping effect, increase the slot liquid pressure, to balance the pressure drop within the machine, spur the liquid return to the h-high end, so as to prevent the leakage, helix seal also called spiral screw thread sealing. |
