Fan-Jin Blower (Recommended Business) -Zhejiang Fan:Tianjin fan , Tianjin blower , Tianjin fan
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, adopt the system installation, install one pipe on the left and right side 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 made of plastic, and the Hubei fan is less than 80cm in length.
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).
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 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. The fan should basically ensure that the viscosity of the paint meets the technical requirements and that there are no quality defects such as leaking spray, bubbles, orange peel, etc. after the 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 nameplate and a product nameplate. The Fujian ventilator guarantees that the riveting is firm, without vibration and deformation, and consistent with the product.
Therefore, a centrifugal fan can run normally. The Hunan fan can not be used for a long time without problems in all aspects, such as painting, installation, operation, and post-maintenance. , The fan can be used for a long time, stable and safe.
Solutions to fan noise
There are 4 ways to deal with the noise of the fan. When the fan used by the company feels noisy, there are 4 ways to deal with it:
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. "Mining Main Fan"
2) A muffler is installed outside the fan exhaust port, with a built-in muffler insert to reduce noise when passing through a specially constructed muffler. The muffler is a useful measure to reduce the radiation of the aerodynamic equipment's intake and exhaust ports or the transmission of noise along the pipe. "Mining energy-saving fan"
3) Silencer shutters should be used as much as possible on the ground shutters. "Counter-rotating fan"
4) The fan is suspended by a damper spring hanger damper.
