Efficient diagonal flow fan mixed flow fan

Efficient diagonal flow fanSlant flow fan, also known asMixed flow fan,It is betweenaxial flow fanandcentrifugal fanThe impeller of the diagonal flow fan allows the air to undergo both centrifugal and axial movementsaxialMotion, the movement of air inside the shell combines two forms of motion: axial flow and centrifugal flow.

The mixed flow fan combines the characteristics of axial flow and centrifugal fans, and is used in situations where the wind pressure and flow rate are neither too high nor too low.

Design a mixed flow fan using the meridian acceleration method and the "quasi three element" flow theory. The fan adopts a conical wheel structure, twisted wing blades, and an inlet with a collector or curved muffler.

purpose

The diagonal flow fan can be used for general ventilation and air exchange under the following conditions:

1. Application site: As an indoor ventilation system for general factories and buildings, it can be used as both an input gas and an exhaust gas.

2. Types of gas transported: air and other non flammable gases, harmless to human body and non corrosive to steel.

3. Impurities in gas: Viscous substances are not allowed in the gas, and the dust and hard particles contained should not exceed 150mg/m3.

4. According to the special needs of users, magnetic motor transmission can also be designed to achieve stepless variable speed and variable air volume structure.

5. Gas temperature: not exceeding 80 ℃.

Efficient diagonal flow fanIt is a type of fan with a specific speed and pressure head between centrifugal fans and axial fans. In a diagonal flow fan, the flow direction of gas in the impeller is at a certain angle to the axis, therefore, the flow of gas has strong three-dimensional characteristics. The diagonal flow fan not only has the characteristics of high pressure coefficient and large operating range of centrifugal fans, but also has the characteristics of high flow coefficient and high efficiency of axial flow fans.
