:>The performance of the mixed-flow fan is within the highest efficiency range. It is divided into five characteristics according to the flow rate. The selection shall be based on the performance table. The performance of the qualified fan shall not exceed % of the total pressure value at the rated flow rate. The performance selection table shows the performance under standard conditions, standard atmospheric pressure, relative temperature % air condition, and the fan installation method can be divided into vertical or horizontal.
: >Structural characteristics
: >The fan is mainly composed of impeller, casing, inlet collector, guide vane, motor and other components. The impeller is welded to the hub using a twisted flat plate with meridional acceleration characteristics. After dynamic balance verification and overspeed testing, it has good aerodynamic performance. The casing is round and is integrated with the air collector with silencer function. The outlet is equipped with a guide plate, which has good air flow distribution and stable pressure.
: >Features of series mixed flow fans
: >The fan has compact structure, easy installation and reliable operation: this fan is better than the axial flow type under the same air volume and pressure. It is small in size, can be directly connected to the air duct, and can be installed horizontally or vertically. It is easy to operate and use
: >Low noise: The casing of the fan is specially designed to greatly reduce the outflow noise. Under the working conditions of unit air volume and unit air pressure, the specific sound level can be reduced by B(), and at the same time, at a lower speed, a higher fan pressure can be obtained. In the air supply and exhaust systems of industrial and mining enterprises and high-end civil buildings, it can replace low-pressure centrifugal fans or high-pressure axial flow fans without requiring a large number of noise reduction measures.
: >Wide range of use: This series of products is divided into single-speed and double-speed models. According to different use occasions, the installation angle of the fan can be changed, the number of blades and the rotation speed can be changed to meet its use requirements. .
