220V 380V Industrial Exhaust Fans , Outlet Flange Radial Centrifugal Fan

Single inlet centrifugal fan industrial exhaust fans forward centrifugal fan outlet flange radial centrifugal fan

We analyze the characteristics of double suction centrifugal fan and single suction centrifugal fan.

1, single suction centrifugal fan:

A. From the structure, the single-side intake ventilator can adopt the cantilever structure, and the transmission mode is more flexible.

B, due to the cantilever structure, the bearing requirements are high. When directly connected, the type of motor directly connected impeller should not be too large or connected with a coupling.

C, single inlet structure, according to different impeller design, can achieve higher pressure.

Using the high pressure, dust removal system, filtration system, all kinds of craft system...

The air inlet end can be directly added pipe.

2, double suction centrifugal fan:

A. The double-sided intake fan must have A shaft through the impeller. The shaft must be supported on the bearing seat on both sides, which has an impact on the air inlet. Due to the double inlet structure, a large air volume can be obtained.

B, air flows into the double suction impeller from both sides of the impeller, the bearing load on both sides is the same, which can basically eliminate the axial force on the impeller, and the wear situation of the two bearings is basically the same.

C, double suction centrifugal fan adopts double support structure, high operation reliability, safety and stability.

Because there are two air inlets, it is usually made into a fan box or machine room to wrap the whole fan.

From the structural characteristics of several aspects:

The single suction centrifugal fan has a wide range of use and is suitable for various parameter working conditions. It is a common centrifugal fan.

Because of the structure, the double suction centrifugal fan is mostly used in large air volume clean gas, commonly used in the air conditioning system.
