| The working principle of a, explosion-proof is the closet 1. When air pressure is higher than 1000 pa, pressure release valve automatically open the exhaust valve, air pressure inside the automatic adjustment, ensure that products are not affected by high pressure impact deformation and damage. 2. When air pressure is lower than 50 pa, automatic control system automatically send alarm and alarm signal output, need to adjust the internal pressure, complementing the success, automatic back to normal, or set the system automatically power when necessary (gb regulation 1 area of low pressure alarm need to cut off the power supply cabinet put oneself in another|s position, 2 area of low pressure alarm can not cut off the power supply). 3. Only the cabinet put oneself in another|s position air pressure meet the specified requirements, the positive pressure blowing control system for effective ventilation cabinet put oneself in another|s position (1 area to seven times replacement cabinet put oneself in another|s free space, 2 area need to replace 5 times cabinet put oneself in another|s free space), when after the completion of the effective ventilation offer cabinet put oneself in another|s position sending signals. 4. Positive pressure ark cabinet put oneself in another|s position within the working pressure of 1000 pa pa 50 P or less or less. Second, the applicable scope of the explosion is the closet 1, for the dangerous sites with explosive air mixture: 0, 1 zone and 2 zone. 2, with explosive air mixture: Ⅱ, Ⅱ, Ⅱ C B A. 3, temperature category: T1 - T6. 4, indoor and outdoor (IP55) 5, combustible dust environment 20, 21, 22 6, the anti-corrosion class: WF1 7. Suitable for petroleum and petrochemical, chemical, textile, printing and dyeing, brewing, pharmaceutical, paint, military facilities and other dangerous explosive environment; Third, explosion-proof are the technical parameters of the closet Explosion-proof marks: ExpeIICT4; Rated voltage: AC220/380 v, non-standard voltage: 12 v / 24 v / 36 v / 127 v / 660 v. Main switch current: 10 a - 40 a; Protection grade: IP54 or IP55 / IP65 / IP66; Thread specification: DN15 - DN100 G4 / G1/2 - inch Lead in specification: diameter 6 mm - 80 mm; Lead wire specifications: 6 mm - 80 mm diameter; Introduction to elicit: top on out, down into the (can not restricted according to customer|s request)  Explosion-proof electrical control box quality certificate number: CNEx17.2985 |
