What's the function of the sealing ring?

Answer:

Basic concepts of mechanical sealsThe mechanical seal is defined by at least a pair of end faces perpendicular to the axis of rotation of the fluid pressure and the elasticity of compensation organizations (or force) the role of the device and auxiliary seal with maintaining relative sliding postmerger and constitutes to prevent fluid leakage. The auxiliary seal of the compensating ring is metal bellows, and is called bellows mechanical seal.
Mechanical seal work should pay attention to the problem1, installation notesA, take great care to avoid installation errors in installation(1) to tighten the gland should be aligned in the coupling bolts should be uniform, to prevent the end cap oblique, with feeler check, the error is less than 0.05 mm.(2) clearance check the gland and the shaft or shaft diameter (i.e. concentricity), around to evenly, not more than 0.01 mm check with the feeler the tolerance.B, spring compression amount should be carried out according to regulations, not allowed to have too large or too small phenomenon, requiring 2 millimeters of error. Excessive assembly increases the face to face pressure, and the other speeds end wear. Too little will cause less pressure than sealing.C, the ring should be installed to ensure flexible movement on the axis, the moving ring pressure to the spring, it should automatically bounce back.
Composition of mechanical sealMechanical seals are mainly composed of the following four components. 1. Main seals: moving ring and stationary ring. 2. Auxiliary sealing parts: sealing ring. 3, pressing parts: spring, push ring. 4, transmission parts: play skip and key or fixed screw.
