Cast Iron Power Plant Fans Centrifugal Horizontal Sectional Multistage Impeller Blower

DINKONDA GLOBAL Power Plants Special D Series High-strength Gray Cast Iron Segmented Compression Centrifugal Horizontal Sectional Multi-stage Impeller Volute Structure Blower

Product Introduction
The D series multi-stage centrifugal blower is a multi-stage compression centrifugal blower equipment, which adopts a horizontally divided multi-stage volute structure and relies on multi-stage impellers to gradually pressurize the gas and output a constant pressure gas source. This model is designed specifically for industrial continuous gas supply conditions. The equipment operates smoothly without pulse, and the output gas is oil-free and pollution-free. It is suitable for the process requirements of multiple industries such as sewage treatment, power, chemical, metallurgy, etc. The whole machine is integrated with a base and assembled and debugged at the factory, greatly reducing the on-site installation workload. It is the preferred equipment for gas supply in large and medium-sized conditions.

Structural Composition
1. Spiral shell body: adopting high-strength gray cast iron segmented shell, horizontally divided structure, easy disassembly and maintenance; The flow channel has been optimized through CFD fluid simulation to reduce internal airflow losses and improve overall operational efficiency. The shell is equipped with dedicated inlet and outlet flange interfaces.

2. Rotor assembly: equipped with multi-stage high-strength centrifugal impellers, which have undergone five axis machining and G2.5 high-precision dynamic balance verification; The spindle is made of high-quality alloy steel and equipped with heavy-duty rolling bearings, which have sufficient bearing capacity and are suitable for long-term uninterrupted operation.

3. Transmission unit: Elastic coupling connects the motor and rotor shaft, buffers operational impact, and isolates vibration transmission; The motor and fan host are fixed as a whole on an integrated steel common base to ensure coaxiality accuracy.

4. Complete set of supporting components: can be matched with imported air filter mufflers, outlet check valves, pressure relief safety valves, flexible compensation joints, on-site temperature and vibration monitoring instruments and other complete accessories to achieve integrated supply.

Product Advantages
1. Wide range of gas supply conditions: the flow and pressure adaptation range is large, and the operating points can be adjusted according to process requirements. A single unit can cover a wide range of gas supply needs, and it also supports parallel expansion of multiple units.

2. Clean gas quality: The compression chamber and lubricating oil area are isolated from each other, and the transported air is free of oil mist and impurities, which can be directly used in production processes that require cleanliness of the gas source.

3. Long cycle stable operation: The rotor has high dynamic balance accuracy, low overall vibration amplitude, low bearing thermal load, supports 24-hour continuous operation throughout the year, and has a low failure rate.

4. Convenient maintenance: The shell is designed with a horizontal split, which allows for easy maintenance and replacement of internal impellers and bearings without the need to remove inlet and outlet pipelines, reducing downtime for maintenance.

5. Excellent noise reduction performance: Paired with imported soundproof filter components, it effectively suppresses intake noise, and the overall noise level of the machine is better than similar Roots blowers, improving the working environment in the factory area.

6. Compatible with multiple motor specifications: supports the selection of ordinary three-phase asynchronous motors, explosion-proof motors, etc., to meet the usage conditions in explosion-proof areas.
