Measuring leakage rate of slide ring seal - mixes leakage fluid in gaseous state with inert gas and measures concentration of leakage fluid in the mixt.

摘要

The leakage rate of a slide ring seal with two sealing rings or plates is measured by feeding the leakage fluid flow in gaseous state into a mixing chamber at atmos. pressure. The fluid is maintained in the gaseous state in the chamber and a quantity of inert gas, which can be mixed with the fluid, is introduced. The gaseous fluid and the inert gas are mixed and the concentration of the leakage fluid in the mixt. is measured in the mixing chamber, or in a measuring chamber connected to it. The leakage rate is determined from the measured concentration. ADVANTAGE - Improved measuring precision, with reduced inertia.
