一、机械密封原理简单的机械密封如图一所示,它是由动环(随轴一起旋转并能做轴向运动)、静环、压紧元件(弹簧)和密封元件(密封圈)等组成。动环靠密封腔中液体的压力和压紧元件的压力使其端面贴合在静环的端面上,形成微小的轴向间隙而达到密封的目的。两密封环端 First, the principle of mechanical seal Simple mechanical seal shown in Figure 1, it is by the moving ring (with the axis rotation and can do axial movement), static ring, pressing components (springs) and sealing elements (seals), etc. composition. The moving ring is sealed by the pressure of the liquid in the sealing cavity and the pressure of the pressing element so that the end face of the moving ring is stuck on the end face of the stationary ring to form a tiny axial clearance.
