Technical requirements for loading and unloading of centrifugal fans

The centrifugal fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. The equipment has two sides. Its technology is divided into two types: feeding and unloading. However, when the upper and lower materials are divided, there are certain technical requirements.

1. Cut the material according to the size, material and other conditions required by the drawing, so that the size of the centrifugal fan blanking meets the requirements of the drawing.

2. The material of the raw material shall meet the technical standards, and there shall be no hardening after oxygen cutting.

3. The machining allowance of the centrifugal fan parts shall not exceed 3~5mm (total machining amount).

4. Clean up the residue.

5. The deformation after oxygen cutting should be corrected after completion.

6. The rust treatment on the surface of the centrifugal fan is clean, the surface is smooth, and there should be no appearance problems such as high point deformation.
