What are the types of explosion-proof? The explosion-proof type can generally be divided into flameproof type (D), increased safety type (E), intrinsically safe type (I), positive pressure type (P), oil-immersed type (O), sand-filled type (Q), and the transmitter is generally flameproof type and intrinsically safe type. Let’s talk about these two types in detail: 1. Flameproof type (D): When the equipment is in normal operation, the parts that can produce spark arc are placed in the flameproof shell, which can withstand the internal explosion pressure without damage, and can ensure that the internal flame gas can reduce the energy when propagating through the gap, which is not enough to ignite the gas outside the shell. 2. Intrinsically safe type (I): The internal circuit of the equipment cannot ignite the explosive mixture under the specified conditions, and the electric sparks and thermal effects generated under normal operation or fault conditions. Depending on the needs of the site, it is important to choose the right type of explosion protection!
