Centrifugal wind turbine is a wind turbine that uses centrifugal force (depending on rotational speed and outer diameter) to do work to increase the pressure of the air by axial inlet and radial air. Centrifugal wind turbine is a wind turbine that uses centrifugal force (depending on rotational speed and outer diameter) to do work to increase the pressure of the air by axial inlet and radial air.
Centrifugal fan wind turbine can be divided into forward tilting wind turbine, radial wind turbine and backward tilting wind turbine according to blade angle.
According to the blade angle of the impeller , the centrifugal impeller can be divided into three types , namely a forward tilting wind wheel , a radial wind wheel and a rear tilting wind wheel .
According to the impeller structure, the impeller can be divided into two types: multi-wing impeller and shunt wheel.
According to motor installation requirements can be divided into outer rotor impeller and inner rotor impeller.
The forward tilting impeller is also known as the forward impeller when the outlet angle of the impeller is greater than 90 degrees. In general, from the radial section of the wind turbine, the angle between the outer side of the blade and the tangent of the turning direction of the point of the blade is obtuse angle, which is the forward tilting wind wheel.
The backward tilting impeller refers to the backward tilting impeller, also known as the backward impeller, when the outlet angle of the impeller is less than 90 degrees. Generally speaking, from the radial section of the wind turbine, the angle between the outer extension of the blade and the reverse tangent of the turning direction of the blade at this point is sharp angle, which is the backward tilting wind wheel.
Generally speaking, the impeller angle of the forward impeller is >90, and then the installation angle of the impeller blade is <90.
The blades of the multi-wing impeller are more than those of the wind turbine, which are more than 30 blades, and are distributed uniformly on the outer side of the upper and lower plate of the impeller. The upper and lower plate edges of the impeller are generally the same.
The outer rotor impeller is the impeller which is mounted on the motor housing. The impeller is fitted with a motor which does not rotate the shaft and the casing rotates. For example, the ceiling fan is the outer rotor motor.http://www.jnblower.com/
