      Working principle of fire exhaust fan :



      Smoke prevention facilities are generally linked with fire alarm systems. When the control center's control console (cabinet) is in an automatic state, after a fire alarm occurs, the smoke prevention system will be linked, and the mechanical pressurized air blower will automatically start. The smoke-proof staircases with natural smoke-exhausting conditions, the front room of the fire-fighting elevator room, or the combined front room are pressurized to prevent the inflow of smoke; at the same time, the fire-proof valve of the corresponding smoke-proof zone is automatically opened, and the mechanical exhaust fan The thick smoke is discharged to the smoke exhaust pipe or shaft through the smoke exhaust port. When the temperature reaches 280 ° C, the smoke exhaust wind will automatically stop.

      When it cannot be started automatically, it can also be started remotely in the fire control center, or directly start the positive pressure blower and exhaust fan at the fan room site.



      After the centrifugal fan is assembled, the centrifugal fan 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 prepared in a certain proportion in advance. Jiangsu centrifugal fan factory basically guarantees 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 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.




      Natural smoke exhaust facilities can not achieve the purpose of smoke exhaust

      Natural smoke exhaust is an economical, simple, easy-to-operate, and convenient way to maintain and manage smoke. However, because some projects are not designed according to specifications during the design and construction process, natural exhaust facilities are often not equipped with exhaust The effects of smoke are mainly analyzed in the following aspects:

      1. The setting position of the natural smoke exhaust window is improper. Considering the effect of natural smoke exhaust, smoke exhaust windows should be installed as close to the upper part of the wall as possible. Guangdong centrifugal fans are currently not installed in the upper part of the wall, Yunnan centrifugal fans, but the lower part, away from the ceiling and ceiling. The large distance is not conducive to natural smoke exhaust.

      2. The window area of the natural smoke exhaust window cannot meet the specifications. The national standard "Code for Fire Protection Design of High-Rise Civil Buildings" clearly specifies the window opening area where natural smoke exhaust is used, but some designers have not calculated it carefully according to the requirements of the code, or calculated the area of fixed windows in the area of smoke exhaust windows. Within this, the smoke exhaust window area of some projects could not meet the specifications, which directly affected the smoke exhaust effect.

      3. The structure of the natural smoke exhaust window is unreasonable. Some smoke exhaust windows are made into non-openable fixed windows, some upper windows are made into fixed windows, and openable smoke exhaust windows are arranged in the lower part of the windows, which seriously affects the smoke exhaust function.

      4. The smoke exhaust window with high installation height lacks an operating mechanism that is convenient for opening. According to the requirements of the specification, the smoke exhaust window should have a device that is easy to open, but some installation heights are high, and the exhaust operation windows that are difficult to open are not equipped with an opening operation device, which is unfavorable for fire smoke opening.
