How to extend the axial flow fan to use the main riveting weldment splicing

Release Time：2021-07-20

The emergence of axial flow fan equipment has brought hope to many industries. In recent years, the market sales of axial flow fan equipment have been good and have been praised by customers. However, some users still do not know how to extend the service life of axial flow fans. Let me show you how to extend the service life of axial flow fans.
1. Be familiar with and understand the operating instructions of the axial flow fan. You can refer to the operating instructions to understand the operating process and related requirements. During the operation, try to follow the procedures and requirements.
2. The axial flow fan strengthens the inspection of the performance of the axial flow fan equipment, and adopts a combination of regular inspection and random inspection to check whether the performance is normal. After an abnormality occurs, it should be eliminated to avoid running with faults.
3, axial fan installation to be stable and reliable, if not sure, can also coordinate the manufacturer designated technical personnel responsible.
4. Do a good job in the maintenance of axial flow fans, clean the outside frequently, and reduce the impact of impurities on equipment performance.
How to make the safe operation of the axial flow fan depends entirely on whether everyone often and correctly maintains the axial flow fan and carries out maintenance, and should pay attention to the occurrence of any failure. If the equipment is not used for a long time, then it is necessary to immediately cut off all the power supplies on the equipment, and put the equipment itself in a ventilated and dry place to prevent rust caused by long-term non-use of the machine.
The riveted welding parts of the ventilator are allowed to be spliced without affecting the performance and appearance quality, but the following provisions shall be met:.
1. Centrifugal fan impeller, impeller wheel disc and wheel cover allow the number of splicing blocks shall not exceed the specific range of axial flow fan, out of the flat wheel cover, the rest of the wheel cover is generally radial splicing.
2. Psychological fan air inlet, impeller diameter is greater than or equal to 400mm A, B type air inlet allows an annular joint near the tangent point of the ring surface and cone surface, C type air inlet allows an elliptical joint near the tangent point, E type air inlet allows an axial joint.
3. The number of splicing blocks allowed for the adjusting door of the centrifugal fan, the cylinder plate and flange ring of the adjusting door are limited to a certain extent, and the joints should avoid the equal dividing holes in Yuanzhou.
