Siping DHF44 parameter DHF44 performance curve Dehui special fan

Models 9-19 and 9-26 series high pressure, commonly used in forging furnaces and high-pressure forced ventilation, are widely used for conveying air and other non self igniting, harmless to human health, and non corrosive gases to steel materials. Its body does not contain viscous substances, and the dust and hard particles it contains do not exceed 150mg/m ³. The gas temperature should not exceed 80 ℃.

The structure of the fan
№ 4-6.3 is mainly composed of impeller, casing, air inlet, bracket, etc; № 7-16 is mainly composed of impeller, casing, air inlet, transmission group, etc.
Impeller: There are 12 blades for the 9-19 type fan and 16 blades for the 9-26 type fan. All belong to the anterior curved leaf type. The peripheral velocity of the impeller diffuser shall not exceed 140m/s. After the impeller is formed, it undergoes static and dynamic leveling

Under the premise of high blast furnace rate and molten iron quality, compared with Roots blower, it has a significant energy-saving effect, reduces noise, facilitates equipment installation, lowers equipment costs, and facilitates maintenance. The 8-09 and 9-12 types of fans can not only be used as blast furnace blowers, but also as fans for various furnaces and forging furnaces. They are also suitable for conveying air and gases that are non corrosive, unnatural, and do not contain viscous objects. They can also be used for material transportation. The medium temperature is 80 ° C.

The impeller consists of 10 backward inclined circular arc blades, a curved front plate, and a rear plate. All are made of steel plates and have undergone dynamic and balance calibration, with good air performance and smooth operation.
