Shenhai Eksplodrezista
Trajtoj
1. Simila Funkcio kun Aldonita Sekureco: Eksplodrezistaj ventoliloj, kiel iliaj normaj ekvivalentoj, plenumi la samajn funkciojn. La ŝlosila diferenco kuŝas en ilia atesto por eksplodsekureco kiel ordonite de naciaj normoj. Ĉi tiuj ventoliloj estas specife ekipitaj per eksplod-rezistaj motoroj.
2. Materiala Kombinaĵo por Sekureco: La komponantoj de eksplodemaj ventoliloj, such as impellers and casings, are made from a combination of soft and hard materials. Tipe, a soft-hard pairing is used for rotating and stationary parts to prevent spark generation from friction or collision during malfunctions. Ofte, impeller blades and rivets are made of 2a01 hard aluminum, while casings are made from galvanized steel or fiberglass.
3. Reliable Performance Metrics: The performance indicators listed in the ventumilo kontraŭ eksplodo specifications represent the effective range, divided into five performance points based on airflow. Selection depends on the performance chart. Certified fire fans must maintain a total pressure value error within ±5% at the rated airflow. The performance selection table is based on standard conditions, unaffected by technical documents or order requirements.
Avantaĝoj
1. Stable and Quiet Operation: The fan’s bracket is welded from steel tubing and angle iron, while the blades are crafted from hot-rolled steel plates. Post-static balance calibration ensures smooth operation with minimal vibration and low noise.
2. Corrosion-Resistant Coating for Enhanced Durability: The casing is treated with epoxy anti-corrosive paint, and the motor is specially designed for corrosion resistance, making it suitable for transporting corrosive gases. The GB35-11 type explosion-proof axial flow fan is designed for brulema kaj eksplodemaj gasoj. Its impeller is made from aluminum alloy to prevent spark generation during operation, and the motor is of the flamrezista variety.
3. Robust and Aesthetic Guard: The guard is constructed from φ5/mm steel wire rope spot welding, ensuring both strength and aesthetic appeal.
4. Convenient and Stable Bracket: The bracket, made from high-frequency welded pipes, offers convenience and stability.
