SHAFT SEAL ASSEMBLY, ESPECIALLY FOR HIGH-PRESSURE TURBOCOMPRESSORS |
摘要 |
A turbocompressor shaft seal, especially for a high-pressure turbocompressor, has each of its gas-side and atmosphere-side slide rings biased toward a rotor ring of the shaft and associated with blocking-liquid compartments which are interconnected by an annular passage around the rotor ring. The compartments are connected in a closed circulation path with a circulating pump and a cooler and leakage liquid is returned by a feed pump to the liquid circulation with the aid of a pressure transformer biased on one side by the gas pressure to be sealed and an adjustable spring force and, on the other side, by the pressure of the blocking liquid.
