Shenhai à prova de explosão
O termo “a prova de explosão” para ventiladores de tambor refere-se ao seu design que isola componentes elétricos capazes de gerar faíscas, arcos, e temperaturas perigosas das misturas de gases explosivos circundantes durante a operação. Este design também garante que nenhuma faísca seja produzida quando situações especiais causarem atrito com a carcaça do ventilador, thus maintaining safe production practices.
Explosion-proof drum fans are generally categorized into two types: one with both the casing and the impeller made of aluminum alloy and powered by explosion-proof motors; and another where the casing is made of iron sheet or stainless steel with an aluminum alloy impeller, also powered by explosion-proof motors. The use of aluminum alloy in friction areas prevents ignition, fulfilling explosion-proof requirements.
Tipicamente, explosion-proof motors like BT4 and CT4 are used, with customization options available for high-temperature resistance, resistência à corrosão, and variable frequency. These drum fans are ideal for flammable and explosive environments, como gás natural transporte.
