Title:
METHOD FOR PREVENTING AND RECOGNISING COOLANT DISCHARGES FROM COMPLEX HYDRAULIC SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2013/110265
Kind Code:
A3
Abstract:
The invention relates to a method for preventing and recognising coolant discharges from complex hydraulic systems. The aim of the invention is to configure such a method in such a way that said method in particular meets requirements for preventing/limiting the production of explosive atmospheres in working areas and for reducing measures previously customarily required for Ex zones. Said aim is achieved in that a circuit conveying coolant is divided into small volumes that have closing valves (1) and a safety valve (4), wherein a leak recognition diagnosis can be carried out by means of a pressure sensor (3) that can be integrated.
