Research Progress in the Bi-direction Non-contact Mechanical Seal Technology
摘要
Abstract
In some high parameter condition,the traditional contact mechanical seal worn badly,life is short,can not take long period run of the equipment requirements. Carry out non-contact mechanical seal especially bi-directional rotary non-contact mechanical seal research in favor of solving the problem. It was summarized of several typical bi-directional rotary non-contact seal reviews domestic and overseas. Using comparative analysis method,comparing related groove profile characteristics of each groove, It was gived that different operating conditions of the bi-directional rotary non-contact seal choosing principle: high pressure and high temperature, large size occasions appropriate chooses circular groove; Low speed occasions appropriate chooses tree groove; Grinding particles of tiny occasions appropriate chooses multi-pore face; High temperature occasion all can choose T-shape groove. Points out that consummating theory model and strengthening the backflow effect, improving the open stability and enhancing T groove steady-state operation temperature range are the development direction of bi-directional rotary non-contact seal technology.关键词
