Title:
OVERPRESSURE ENCAPSULATION SYSTEM FOR EXPLOSION PROTECTION, AND CORRESPONDING OPERATING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/084743
Kind Code:
A8
Abstract:
The invention relates to an overpressure encapsulation system for explosion protection, comprising the following: - a device (1), in particular a painting robot (1), - an overpressure-encapsulated device housing (2) comprising a housing outlet (6) for discharging gas out of the device housing (2), - a compressed air system (3, 4) for operating the device (1), said compressed air system (3, 4) being arranged within the device housing (2), - a sensor assembly (7, 8, 9) for measuring at least one fluid variable (Q, PI, PA), and - an analysis unit (11) which analyzes the fluid variable (Q, PI, PA) measured by the sensor assembly (7, 8, 9), in particular in order to detect a leakage of the device housing (2). According to the invention, when a leakage of the device housing (2) starts, the analysis unit (11) ascertains a remaining run time until a required maintenance operation or until a system failure on the basis of the measured fluid variable (Q, PI, PA) and/or detects a fault (14, 16) of the compressed air system (3, 4) on the basis of the measured fluid variable (Q, PI, PA). The invention further relates to a corresponding operating method.
