Fan management method
Fan noise reduction In addition to the air outlet noise considerations, according to the site conditions, the body noise of the fan and the solid-borne sound transmission of the oscillation should also be paid attention to.
Because the axial flow fan announces a lot of noise during operation, and the fan noise also progresses with the increase in air volume and pressure. Generally, there are several ways to deal with fan noise questions:
1) The noise of the casing and the motor can be treated by installing a sound insulation cover. The fan is placed in an independent fan sound insulation room, and the sound absorption and sound insulation processing is performed in the fan room.
2) The muffler is installed outside the fan exhaust port, and the built-in muffler inserts reduce the noise when passing through the muffler with special structure. The muffler is a useful way to lower the aerodynamic equipment's intake and exhaust radiation or to transfer noise along the pipe.
3) Silent shutters should be used as far as possible on the ground floor shutters.
4) The fan is suspended by a damper spring hanger damper.
Make targeted planning based on factors such as sound source objects, noise characteristics, noise reduction requirements, process conditions, and device orientation to ensure that outstanding noise reduction and noise reduction are achieved.
After the centrifugal fan is assembled, it needs to be spray-painted, mainly to improve its cleanliness and improve its anticorrosive performance. Therefore, once the spray painting effect is not good, it will cause a certain impact on the fan. The fan, for example, shortens its service life, is easily corroded, and speeds 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, the Anhui ventilator 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 its long-term use is inseparable from all aspects of its functions, such as painting, installation, operation, and later maintenance. Therefore, as long as all aspects of the fan are in place, Jiangxi fan , The fan can be used for a long time, stable and safe.
Jin Blower Group-the precautions for roof fan installation are as follows:
1. In order to avoid that the position of the fan motor power tube and the fan power connector are not on the same side, measures are taken:
a. Adopting the system installation, Jiangsu Fan Factory, install one pipe on the left and the right of the fan;
b. Specify the left and right entry requirements on the order requirements according to the site conditions when ordering;
c. Some fan terminals have been repositioned and remodeled.
2. The end of the motor power supply must have a waterproof bend. The metal hose is plastic-coated and the length does not exceed 80cm.
3. Fan installation should be performed after the civil foundation leveling is leveled or tiled.
4. A 40x4 grounded flat steel is embedded in the power pipe, and the flexible connection of the metal duct is ≥4mm2 flexible wire or copper braided tape to make the grounding bridge in time.
5. Install a rain cover at the fan mouth, and then install a protective cover (steel mesh).
