The external axial flow fan of the motor can be connected as a part of the pipeline between pipelines, suitable for conveying air below 60 ℃ and various harmless gases to the motor in chemical, papermaking, and other factories.

This type of fan is divided into 5 machine numbers according to its impeller diameter: No. 6, 7, 8, 9, 10, etc. There are two types of leaf numbers: 4 and 6. The blade installation angle can be made into four types: 15 °, 20 °, 25 °, 30 °, etc. The motor is installed on the upper part of the air duct, with an adjustable motor base plate supporting the motor and adjustable center distance. All are transported by V-belt. The bearing box is fixed inside the sealed protective cylinder of the air duct and isolated from the medium. This fan is generally made of welded steel. If it transports corrosive or flammable gases, requirements can be made at the time of ordering

1.Before installation, the fan should be carefully inspected for any damage or deformation. If there is any damage or deformation, it should be repaired properly before installation can proceed.

2.During installation, attention should be paid to checking for any looseness in the inferior parts, and the gap between the blades and the air duct should be even and not collide.

3.The weight of the connecting air duct should not be borne by the fan's duct, and additional support should be added during installation.

4.A collector must be installed at the air outlet of the fan, and a protective net must be installed.

5.The fan base must be naturally connected to the foundation plane, and the base must not be forcibly connected by knocking to prevent deformation. During installation, it should be calibrated

6.Stand on the main machine, add shims, maintain a horizontal position, and then tighten the foundation bolts.

7.After installation, it is necessary to conduct experiments and wait for normal operation before allowing formal use.

Maintenance

Users should do a good job in daily maintenance and upkeep of the fan to ensure its normal and safe use. It is recommended to pay attention to checking:

1Is the air flowing through the fan clean and dry, without impurities or excessive water vapor.

2When the fan is idle and reused, it must be checked whether the connecting parts are firm and reliable, whether the rotation is flexible, and tested before it can be officially used.

3Pay attention to whether there is any abnormal sound or increased vibration during the operation of the fan in daily life. If any abnormal situation is found, stop the machine for maintenance in a timely manner.

4Clean the dust and dirt on the fan blades in a timely manner.
