Hello everyone, Lin Fei to answer the above questions, roof fan vertical installation diagram, roof fan installation diagram many people do not know, now let's take a look!

What is a roof ventilator? In fact, the roof ventilator is divided into many categories according to the air volume and pressure, and the installation of the roof ventilator will have different installation points according to these differences. The following is a brief introduction for you according to some precautions in the installation and use of the roof ventilator.

3. It adopts advanced CAD software and adopts multi-objective optimization design. There are eight kinds of fans in the DWT- series, with 12 fans and 2 fans. By changing the speed, angle and blade profile, expanding the range of performance parameters to meet the needs of different working conditions, configure fans and systems to achieve energy saving and noise reduction. Stable operation, long service life, small moment of inertia, high accuracy of dynamic stability, stable operation, various performance indicators of the enterprise modern standards are higher than the fan industry standards, ensuring the leading position of the fan in the industry. It has a wide range of application, and the fan can be made into an explosion-proof type according to the use requirements, which is suitable for the forced exhaust of flammable, explosive and corrosive gases; after repeated testing by the provincial and municipal technical supervision bureaus, users can rest assured to use.

4. the foundation of the roof ventilator should be higher than the roof, the surface should be flat, prevent water leakage, and pre-embedded anchor bolts. A layer of 5mm rubber plate is placed between the fan base and the foundation to reduce vibration, and the anchor bolts should be equipped with spring washers to prevent loosening in use. The diameter of the roof ventilator outlet can only be larger, not smaller. Finally, an anti-insect net should be installed at the exit and a rain cap should be added when the exit is on the upper side. If it snows and freezes in winter, it must be started frequently to prevent heavy snow from blocking the fan outlet. Connect the flexible hose (flexible material, non-flammable) to the roof ventilator pipe, the length is not less than 200mm, and the pipe diameter is the same as the inlet and outlet size of the roof fan. In order to ensure that the hose will not deform during the operation of the system, the tightness of the hose should be moderate. For the canvas hose installed at the suction end of the roof ventilator, it can be slightly tightened to prevent the roof ventilator from being sucked up during operation and reduce the cross-sectional size of the canvas hose.

5. The roof ventilator is installed on the roof for ventilation. Due to the particularity of the installation and use environment, the material and structure of the fan have its particularity. The roof ventilator is equipped with a device to prevent air backflow after shutdown, because the fan rotates at a high speed under the action of hot pressure, resulting in a great increase in the wind speed in the fan tube. Fan reversal is very disadvantageous to motor start-up and may be damaged due to excessive start-up current. The design of roof ventilator should have reliable rain-proof, snow-proof and sand-proof performance. Snow and sand are not like rain, because when the outdoor wind speed reaches a certain intensity, snow and sand will enter the fan not only from the upper part, but also from the lower part.

6. Today's article introduces the main points of installation and use of roof ventilator for you. I hope it will be helpful to you. Roof ventilator is an efficient mechanical device for gas compression and transportation, which relies on mechanical energy to discharge gas.
