Verfahren und Vorrichtung zur verschleiß- und leckage-kontrollierten volumetrischen Dosierung einer fließfähigen Komponente

摘要

In a process for the wear- and leakage-monitored volumetric dosing of a fluid component, the metered volume flow is monitored both volumetrically and gravimetrically by continual measurement and storage of the volume flow resulting from the dosing action, the associated pressure and where appropriate the prevailing temperature; the volume change delta V brought about by the pre-compression, and thus the specific compressibility of the component given by formula, is measured at each metering cycle, stored and compared to a corresponding pressure- and temperature-dependent reference value. In the event of a fault being reported, inspections are carried out on all components liable to wear and leaks. Also described is a device for carrying out the process.
