Overview

The explosion-proof stainless steel positive pressure explosion-proof control cabinet in the sulfuric acid workshop is a type of positive pressure cabinet with explosion-proof performance. With the rapid development of industries such as kerosene chemical, metal smelting, and chemical pharmaceuticals, the use of explosion-proof positive pressure cabinets in system control is becoming increasingly widespread. How to accurately utilize positive pressure explosion-proof controllers in explosive gas injury scenarios. Due to the inability of electrical equipment deployment to prevent the generation of electric sparks or the formation of hot surfaces during incidents, once they come into contact with explosive gas mixtures on site, it can lead to the occurrence of explosions and chaos, directly endangering the property and safety of users.

Explosion proof stainless steel positive pressure explosion-proof control cabinet for the second worker in the sulfuric acid workshop

Product Introduction

When the air pressure exceeds 1000Pa, the pressure relief valve automatically opens the exhaust valve and adjusts the internal air pressure to ensure that the product is not deformed or damaged by the impact of high air pressure.

When the air pressure is below 50Pa, the automatic control system will automatically issue an alarm and output an alarm signal. The internal pressure needs to be adjusted, and when the air supply is successful, it will automatically return to normal. Otherwise, if necessary, the system can be set to automatically power off (according to the national standard, the low pressure alarm in Zone 1 needs to cut off the cabinet power supply, while the low pressure alarm in Zone 2 does not need to cut off the power supply).

3. Only when the cabinet pressure meets the specified pressure requirements, the positive pressure blowing control system will effectively ventilate the cabinet (7 times the free space of the cabinet needs to be replaced in Zone 1, and 5 times the free space of the cabinet needs to be replaced in Zone 2), and provide a signal to power the cabinet after effective ventilation is completed.

The working pressure inside the positive pressure cabinet is 50Pa ≤ P ≤ 1000.
