Shandong Grid Group Co

Greed Mixed Flow Fan Manufacturer
Performance Selection
The performance of the fan is within the highest efficiency range. The performance is divided into five characteristics according to the flow rate. When selecting, the performance of the qualified fan shall be within the rated range. The total pressure value under flow rate does not exceed. The performance selection table is the performance under the standard state. The standard state is atmospheric pressure, relative temperature, air state. 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. It has good aerodynamic performance after dynamic balance calibration and overspeed test. The casing adopts a circular shape and is connected with an air collector with a silencer function to form a whole. The outlet is equipped with a guide plate for good air flow distribution and pressure stability.
Features of Series Mixed Flow Fans
The fan mechanism is compact, easy to install and reliable to operate. The fan is smaller than the axial flow type under the same air volume and pressure. It can be directly connected to the air duct for horizontal installation or vertical installation. It is easy to operate and use. Features
Low Noise The fan casing is specially designed to greatly reduce outflow noise. Under the operating conditions of unit air volume and unit air pressure, the specific sound level can be reduced and a higher fan pressure can be obtained at a lower speed. 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 application This series of products is divided into single-speed and double-speed models. According to different usage occasions, the installation angle of the fan can be changed, the number of blades and the rotation speed can be changed to meet the usage requirements.
