Quotation for radial fully open material conveying fan​

IRO modelRadial fully open material conveying fanDue to its use in conveying airflow with heavier particles, the impeller needs to have certain wear resistance, and its structural design is generally focused on heavy-duty design. this kind ofThe impeller does not have a front or rear disc, and the blades are purely radial. This type of impeller can prevent the material it transports from accumulating inside the impeller and causing it to lose dynamic balance. Although there are no front and rear disks, the blade design and reinforcement are of high-strength grade, with a wide range of operating parameter points to ensure stable and long-lasting operation.

The main structure of the fan

1. Impeller: Adopting a welded structure and an open impeller, its blades are made of wear-resistant alloy steel plates. After machining, they undergo dynamic and static balance correction, ensuring smooth operation.

2. Shell: Welded into a snail shaped whole shell with ordinary steel plates.

3. Air inlet: It is welded together with a reasonable conical integral and rectifier, and fixed to the casing with bolts.

4. Transmission group: using rolling bearings.

5. Bracket: Made of ordinary steel plates welded together and fixed to the casing with bolts.

Selection and Application of Fan Performance

1. The design and usage unit selects the fan number based on the required flow rate and total pressure, and the specific motor used must be checked from the performance and selected components.

2. The performance of each revolution in the performance and selection table is divided into eight performance points based on flow rate within the range of 90%. When ordering, the performance table can be used as the reference.

3. The qualified product performance of the fan factory is that the total pressure value does not exceed ± 5% at the rated flow rate.

4. Performance and selection are based on t=20 ℃, atmospheric pressure P=101325Pa, gas density 1.2kg/m3Calculation of air medium.
