Jiangsu Steel Cord widespread use of centrifugal fans for sewage odor, gas purification, acid corrosive gas pump drainage. The maximum operating temperature is 80 ℃, Jiangsu Steel Cord centrifugal fan casing, inlet bell, impellers are pure glass, steel, completely changed the production process of traditional glass-lined carbon steel. Enclosures and metal framework forming the connecting bolts coated with the overall approach, completely solve the bolt damage due to corrosion caused by the phenomenon. Fans with double base, without dismantling bolt, easy to maintain fan. Fan shaft seals do special seal treatment to prevent leakage of poisonous gases. Safety requirements: structural strength, low vibration and RSR 1. ANSYS stress rotor dynamic analysis performed whole crew, and strengthen security. (Other domestic manufacturers have not done this) 2. impeller balancing line with ISO1940 specifications of 2.5MM \ S grade. 3. After the fan assembly in accordance with AMCA 210-85 test, in line with ISO2372 specifications of the unit vibration 4.5MM \ S grade. (GB is 6.3MM \ S grade) A. shell molding process as a whole, increasing the strength of the casing (outer membrane design, appearance look better) B. entrance bell shape using speakers to enhance the smooth flow field, reduce noise and damage the inlet bell C. the impeller and the gap is less than 5mm, reduce performance loss, and is a line contact, can reduce the crystals attached to the inlet bell. (Mostly domestic fan over 5MM) high performance high efficiency, low noise and low vibration top margin fan, buy the rest assured
