The material conveying fan pneumatic conveying system uses the positive-pressure airflow generated by a Roots blower as the conveying power, continuously transporting materials supplied from the lower material source to the subsequent storage chambers. The warehouse is equipped with a dust removal device located at the top of the warehouse, which can separate the gas containing the materials being conveyed into the warehouse.
The material conveying fan pneumatic conveying system uses the positive-pressure airflow generated by a Roots blower as the conveying power, continuously transporting materials supplied from the lower material source to the subsequent storage chamber. The warehouse is equipped with a dust removal device located at the top of the warehouse, which can separate the gas containing the transported materials.
When the system is running, start. Material conveying fan A high-pressure column of air is generated. This high-pressure air column creates a negative pressure inside the Venturi jet pump, instantly drawing the material supplied by the rotary feeder into the nozzle of the Venturi jet injector. The material is then transported via a water-carrying pipeline to the storage warehouse. Subsequently, a warehouse-top vacuum cleaner installed on the roof of the warehouse separates the material from the transport air stream. The remaining air stream is promptly exhausted outdoors, preventing excessive dust accumulation at the site.
The material conveying fan adjusts the flow rate by varying its rotational speed while keeping the valve and damper openings constant. Essentially, this method saves energy by reducing fluid动力. This control approach can fundamentally eliminate the widespread phenomenon of "overpowering a small load"—a common source of energy waste in fans and pumps caused by improper equipment selection or changes in load. It also removes the throttling resistance imposed by dampers, ensuring that fans and pumps always operate at their optimal performance conditions.
Material conveying fan The performance advantages are as follows:
1. Ultra-quiet and silent: The motor operates directly, and an integrated needle mechanism has been added to achieve a silent effect.
2. High reliability and stable pressure. Excellent operational balance performance, with high mechanical precision. The components of the working section have undergone highly precise balancing design, testing, and adjustments, resulting in extremely low vibration levels. The unit complies with the IP55 protection rating, and its Class F motor boasts high efficiency with virtually no failures. An axial sealing test is conducted between the motor and the blower to prevent foreign objects from entering. Furthermore, to ensure optimal performance, each material-handling blower undergoes rigorous testing before leaving the factory.
3. Energy-saving and environmentally friendly: The material handling fan is made from ADC12 material, representing a breakthrough over the traditional casting iron process. Its impeller features characteristics such as contact-free operation with other components, no need for lubrication, no oil contamination, and boasts attributes of “high precision, high quality, and lightweight.” This product boasts high technological content, energy efficiency, low carbon emissions, and superior quality.
4. Easy to install. Compact in size and lightweight, with a specially designed shock-absorbing bracket that significantly reduces vibrations generated during fan operation.
5. Wide range of applications. Material conveying fan A 50/60Hz wide-band motor can be used simultaneously, and different voltage specifications can be selected according to customer requirements. The material conveying fans are available in both high-capacity and high-pressure series, offering customers greater flexibility when making their selection.
6. Maintenance is simple. Apart from the impeller, the material-handling fan has no other moving parts. The impeller is directly connected to the motor, gears, and belt drive, ensuring high reliability and virtually eliminating maintenance requirements, thereby significantly reducing operational and maintenance costs.
