Therefore, as a widely used product, the American Expo brand explosion-proof positive-pressure cabinet and its positive-pressure purging control system have already gained widespread recognition and high praise from customers.Explosion-proof Positive PressureStrengthCabinetProductintroduction

When the standard air pressure is less than 50Pa, the automatic control system automatically emits sound and export alarm signals. The internal working pressure needs to be adjusted. When the air supply is successful, it automatically recovers. Otherwise, if necessary, the system software power-off protection should be set (national standards require that low-pressure alarm in Zone 1 requires disconnecting the cabinet power supply, while low-pressure alarm in Zone 2 may not require power cutoff).。3. Only when the cabinet standard air pressure reaches the specified standard air pressure level, the positive pressure purging automatic control system will allow reasonable ventilation of the cabinet (Zone 1 requires replacement of 7 times the cabinet volume space, Zone 2 requires replacement of 5 times the cabinet volume space). When reasonable ventilation is completed, a signal is given to the cabinet power distribution.。4.Positive PressureStrengthCabinetCabinetItselfStructureDomestic的IndustryOperatingWin the BidStandardair pressureFor50Pa≤P≤1000Pa。Application Fields of Positive-Pressure Purge Automatic Control System for Explosion-Proof Positive-Pressure Cabinets

InvincibleSameCountry Or InvincibleArea，AccordingVariousSelfstandardizedAreaPlanExplosion Hazardous Area。In China, based on the frequency and duration of occurrence of explosive gas mixtures, explosive gas environments are divided into Zone 0, Zone 1, and Zone 2 (consistent with IEC international standardization). Zone 0: Environments where explosive gas mixtures occur continuously or for long periods. Zone 1: Environments where explosive gas mixtures may occur during normal operation; generally, explosion-proof cabinets are suitable for X model series positive-pressure purging automatic control systems or Y model series positive-pressure purging automatic control systems.Zone 2: Environments where explosive gas mixtures are unlikely to occur during normal operation, or if they do occur, they exist only for a short time; generally, explosion-proof cabinets are suitable for Z model series positive-pressure purging automatic control systems. Zone 0 typically exists in closed containers, storage tanks, and other internal gas spaces. In actual design, Zone 1 rarely exists, and most situations fall under Zone 2.
