What are the technical parameters of the high-pressure centrifugal fan?

2020-07-15

The impeller is a forward curved blade. The peripheral speed of the outer edge of the impeller diffuser does not exceed 140m/s. After the impeller is formed, the static and dynamic balance are corrected, the air performance is excellent, the efficiency is high, and the operation is stable and reliable. The air inlet of the high-pressure centrifugal blower is made into a convergent streamlined overall structure, installed on the side of the fan; the cross-section parallel to the axial direction is a curved shape, which can make the gas enter the impeller smoothly with less loss.


Advantages: Compared with similar fans at home and abroad, it has the advantages of high efficiency, low noise, flat performance curve, and wide efficient area.

Material: stainless steel, iron, etc.; matters needing attention: the transportation medium generally does not exceed 50°C (not exceed 80°C), and the dust and hard particles contained in the medium are not more than 150mg/m2.


Before choosing a high-pressure centrifugal fan, you should understand the production and product quality of domestic high-pressure centrifugal fans, such as the types and specifications of the high-pressure centrifugal fans produced, the special uses of various products, the development and promotion of new products, etc., and full consideration should be given to them Environmental protection requirements, in order to choose the best use of fans. According to the different physical and chemical properties of the gas transported by the high-pressure centrifugal fan, choose high-pressure centrifugal fans for different purposes. If you transport corrosive gases, you should choose anti-corrosion high-pressure centrifugal fans.


The selection of high pressure fan needs to be carried out in the following two steps:

The turbine fan needs to determine what function of the high-pressure fan is used on site, whether it is suction or blowing, and find the pressure-flow curve corresponding to the high-pressure fan; if you read the wrong curve, sometimes the selected product cannot be used;


According to the calculated pressure and flow, find the operating curve above the operating point corresponding to the pressure and flow on the graph; then select the type of high-pressure fan based on the operating curve.
