Antimony Impregnated Carbon Ring Seal Rings For Nitrogen Operation Condition


Features:


ZC carbon manufactures and sells kinds dimensions of impregnated carbon graphite seal rings,which meets details with operation condition in carbon ring seal system.


The carbon ring seal is mostly a non-contact seal that is a floating ring seal gas. Its sealing principle is to form a gas film between the floating ring and the sleeve by the sealing gas, which generates a throttling and depressurization, and prevents the high-pressure side gas from flowing to the low-pressure side. In operation, the force of the floating ring is similar to that of the bearing. The difference is that for the bearing, the shaft floats and the bearing bush is fixed. The oil film of the shaft rotates to produce the oil film buoyancy to lift the shaft. For the floating ring, The weight of the floating ring is small, and the air film generated in the floating ring and the shaft gap when the shaft rotates can lift the floating ring, and the shaft is relatively fixed. According to the bearing oil film principle, if the floating ring and the shaft are completely concentric, the buoyancy of the air film will not occur. For example, when the floating ring and the shaft are eccentric, the buoyancy of the air film will occur when the shaft rotates, and the buoyancy causes the floating ring to float and the eccentricity is reduced. small. When reduced to a certain extent, the buoyancy generated is exactly equal to the weight of the floating ring, achieving dynamic balance. Since the floating ring is very light, the eccentricity of the dynamic balance is small, that is, the floating ring is automatically kept concentric with the shaft, which is an advantage of the floating ring seal. Under normal working conditions, the floating ring and the shaft (or bushing) are basically in non-contact state, and a circular small groove is formed in the inner surface of each carbon ring. When the gas passes through the small groove, a gas vortex is formed here to block the medium gas, thereby achieving the sealing purpose. , so the floating ring seal can be used on the rotating shaft seal under higher parameters.
