Microcirculation type mechanical seal control method

The invention relates to the field of mechanical sealing, in particular to a microcirculation type mechanical sealing control method which comprises the following steps: S1, forming a flowing groove in a working surface of a static non-compensation ring; and S2, according to the required end face specific pressure pc, media with different viscosities are introduced into the flowing groove, and the liquid film back pressure coefficient lambda is changed. The dynamic performance of the mechanical seal can be adjusted according to different working conditions. 本发明涉及机械密封领域，具体是一种微循环式机械密封控制方法，包括如下步骤：包括如下步骤：S1、在静止式非补偿环的工作面开设流动槽；S2、根据需要的端面比压pc，向流动槽内通入不同粘度的介质，改变液膜反压系数λ。本发明针对工况的不同可对机械密封进行动态性能调整。
