What is the difference between flameproof and positive-pressure explosion-proof boxes?
Explosion-proof boxes are the most widely used power distribution equipment, with relatively comprehensive explosion-proof forms. The most common types are flameproof and positive-pressure explosion-proof boxes, which can almost meet all usage requirements. Most users do not understand the differences between flameproof and positive-pressure types. Here, Hualong explosion-proof box manufacturer introduces the flameproof type and positive-pressure type.

Oil and gas recovery treatment devices used in refineries and oil depots are in hazardous environments with flammable and explosive gases and must meet explosion-proof requirements. There are mainly four process methods for oil and gas recovery: absorption, adsorption, membrane separation, and condensation. VOCS analyzers are core devices, and VOCs cabinets and other non-explosion-proof.

According to the relevant provisions of the State Council's "Measures for the Administration of Production Licenses for Industrial Products", all enterprises, institutions, and individuals that produce and sell explosion-proof electrical products within the territory of the People's Republic of China, regardless of their nature or affiliation, must obtain a production license to qualify for producing such products. Without a production license, they are not permitted to produce them.

Positive-pressure explosion-proof station houses are widely used in areas such as onshore petroleum exploration and offshore platform petroleum exploration zones. These areas may contain explosive gases and fall under Zone 1 and Zone 2 of Class II explosion-proof classifications. Machinery and equipment operating here face hazardous working conditions, and instruments, meters, and oil and gas storage and transportation equipment require special process treatment and control.

The five major advantages of an explosion-proof positive-pressure cabinet: beautiful appearance and flexible structure, which can be designed according to actual conditions, such as upper-lower type, left-right type, or console type. Stable explosion-proof performance: from the explosion-proof principle, the flameproof type allows internal explosion but does not allow flame propagation; the positive-pressure type does not explode internally. Therefore, in the event of an explosion.

Explosion-proof types are divided into: flameproof, intrinsically safe, increased safety, positive-pressure, encapsulated, oil-immersed, sand-filled, and non-sparking types. This article mainly introduces the explosion-proof principles and characteristics of three common typical explosion-proof types: flameproof, intrinsically safe, and positive-pressure types. The explosion-proof principles, advantages, and disadvantages of flameproof, intrinsically safe, and positive-pressure types: flameproof.
