After the assembly of the centrifugal fan, the roots fan needs to be spray-painted, mainly to improve its cleanliness and anticorrosive performance. Therefore, once the painting effect is not good, it will cause certain effects on the fan, such as shortening its service life, easy to be corroded, and speeding up the damage of various parts. Therefore, when spray painting, special attention must be paid to avoid poor paint quality.
1. Before spraying the centrifugal fan, it must be handled in place, which specifically involves degreasing and decontamination. At the same time, it is necessary to confirm that the welding and the surface of the parts are smooth. No appearance defects are allowed. Good surface packaging.
2. Of course, the cleanliness of the environment is also important for the paint quality of the fan. Therefore, the dust on the ground and surrounding objects must be cleaned; the pressure of the air pump should be adjusted to not less than 4MPa, and the spraying device and objects should not exceed 30cm.
3. The paint used for centrifugal fan spraying must be matched according to a certain proportion in advance. Basically, it is necessary to ensure that the viscosity of the paint meets the technical requirements and that there are no quality defects such as leakage spray, bubbles, orange peel, etc. after spray painting is completed. After the fan finishes the rust-proof paint twice and finishes the paint twice, it is ensured that the appearance of the fan is bright, smooth, and has good adhesion, which meets the technical requirements.
4. Due to the hidden safety hazards in the production process of the motor wheels, V-belts and other moving parts of the centrifugal fan, it should be sprayed with eye-catching paint. The dried or naturally dried machine is riveted with a label and a product nameplate to ensure that the riveting is firm, not subject to vibration and deformation, and consistent with the product.
Therefore, a centrifugal fan can run normally, and it can not be used for a long time without problems in all aspects, such as painting, installation, operation, and post-maintenance. Long-lasting, stable, and safe to use.
Jin Blower Group-the main uses of mine fans:
Mine explosion-proof withdrawable main ventilator can be applied to the ventilation of coal mines and metal mines, chemical mines, tunnels, and civil air defense projects. Mine flameproof local ventilator is mainly used in mines and other industrial sectors to transport gas, coal dust and flammable gas.

The noise during the operation of the anticorrosive fan gradually increases, which will not only affect the workers in the factory, but also the surrounding environment. Fujian Roots fan is a type of environmental pollution and Jiangxi Roots fan. . So what are the reasons and solutions for increasing fan noise? Let's take a look:
1. Check if the motor frequency is correct
Adjust the corresponding frequency operation.
2. Check if the motor wiring method is correct
Adjust the correct wiring method.
3. Check whether the bearing is damaged
The operating specifications for replacing the motor bearings are based on work standards.
4. Check whether the anti-corrosion fan sucks the foreign object and whether the air pipe is blocked.
Clean foreign objects and clean the air duct.
5. Detect the disturbance of air flow, the resonance caused by the impact, the resonance phenomenon of reflection
Add a muffler to the duct and isolate the noise or add a soundproof box to the fan
6. Check whether the anti-corrosion fan bearing is damaged
Replace the fan bearing. The replacement method is based on the fan bearing replacement work standard.
7. Check if the duct is noisy, if there is a co-vibration duct, if the wall is too thin
Add support to the duct or add acoustic insulation to the duct.
8. Check if the fan running direction is correct
Adjust the fan running direction.
9. Check if the fan belt is loose and making noise
Replace the belt and adjust the tightness of the belt.
