惯性密封是指利用密封腔内旋转的液体在牵连惯性力的作用下处于相对平衡状态这一流体静力学特性,使液体的自由面高度和密封腔保持相对静止,或在一定范围波动,但不从密封腔流出造成泄漏的密封。惯性密封属于流体动力密封的范畴,是无接触密封。因此这种密封最大的特点是具有相当长的使用寿命,在泵的使用过程中,可不对密封进行更换和修理,这是机械密封、填料密 Inertial sealing refers to the use of the liquid in the sealed cavity under the influence of the inertial force implicated in a relatively balanced state of the hydrostatic nature of the free surface height of the liquid and sealed chamber remain relatively static or fluctuate within a certain range but not A seal that leaks out of the seal chamber. Inertia seal is the category of hydrodynamic seals, is a non-contact seal. Therefore, the biggest feature of this seal is a very long life, in the process of using the pump, the seal can not be replaced and repaired, which is a mechanical seal, packing
