With the rapid development of industries such as kerosene chemical and metal smelting, the use of explosion-proof positive pressure cabinets in system control is becoming increasingly widespread.

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 interact with explosive gases on site

Encountering mixed substances can lead to explosions and chaos, directly endangering the property and life safety of users.

1. The product shell is formed by welding steel plates or stainless steel, and the surface is subjected to high-speed shot blasting and powder electrostatic spraying, resulting in a beautiful appearance;

2. The explosion-proof positive pressure cabinet consists of two parts: the cabinet body and the positive pressure blowing control system device. The air source of the explosion-proof positive pressure cabinet enters the cabinet through the positive pressure blowing control device

When the body is blown and reaches the safe air pressure requirement, the positive pressure blowing control device will output a signal alarm when the low pressure alarm is triggered, and if necessary, the power supply of the positive pressure cabinet will be cut off.

3. Under the control of the positive pressure control system, the positive pressure cabinet is filled with protective gas, and the pressure inside the positive pressure chamber is higher than the pressure outside the positive pressure chamber, forming a safe micro positive pressure

The small environment prevents flammable and hazardous gases from entering the positive pressure chamber, ensuring the safe operation of ordinary instruments and electrical components inside. Automatic control system

The system mainly completes high-end functions such as ventilation, air replenishment, automatic release of ultra-high pressure, low pressure alarm, and low pressure interlock power-off.

It can be produced according to the electrical schematic provided by the user, and the product can be equipped with detection instruments, analysis instruments, display instruments, low-voltage electrical appliances, frequency converters, etc

Soft starters or computer control systems can serve as central signal processing systems and central control systems.

Application scope of explosion-proof positive pressure cabinet:

1. Zone 0, Zone 1, Zone 2.

2、　ⅡA、ⅡB、ⅡC。

3. Temperature groups T1 to T6.

4. Indoor and outdoor (IP55)

5. Flammable dust environment zones 20, 21, 22

6. Suitable for explosive hazardous environments such as petroleum and petrochemical, chemical, brewing, painting, textile, printing and dyeing;
