Industrial Fans and Blowers from Henan Xianrun: The difference between the axial fans and centrifugal fans

Centrifugal fans and axial fans except that:
1, centrifugal fan to pull air flow tube change media, but does not change the axial fan air flow pipe medium;
2, the former air volume and pressure are large, the former air volume and pressure are very low;
3, the former installation is more complex, which is relatively simple to install;
4, the former motor and fan is typically connected by a shaft, which is generally in the fan motor;
5, see the former Chang An air conditioning unit installed in the inlet and outlet of the boiler drum, induced draft fan, and so on, which is often installed in the duct which, or the front end of the outlet duct; centrifugal fan is a little big head wind. The axial fan is strong wind and small head. Centrifugal fans single typhoon amount is difficult to do so much and axial fans 1, both of which function Purpose: To overcome the resistance to fluid flow, the fluid must have a certain amount of pressure energy. Fans (and pump) is the fluid pressure can produce fluid machine.
2, the function definition:
① When the high-speed centrifugal impeller rotating by inertial force generated by the impeller can increase the pressure of the fluid. Often used in a relatively small flow rate, the pressure can be relatively larger occasions.
② by the axial-flow type impeller rotating at high speed, the lift generated by the impeller can increase the pressure of the fluid. Generally used in a relatively large flow rate, the pressure can be relatively smaller occasions.
