Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. How to use the roof ventilation fan: Speaking of natural ventilation roof fan Steel plant, you have to talk about its advantages. From the perspective of professional speaking, there are three advantages of roof fans, let's look at the specific. One is the smooth operation and long life: Turn the small inertia, high dynamic smooth precision, smooth operation, and the performance requirements are higher than the industry standard for natural ventilation fan factory, to ensure that the kind of fan at the leading position in the peer. The second is the wide range of applications: This fan can be used according to requirements made into explosion proof, for flammable, explosive and corrosive gases with forced ventilation occasions. In other words, almost all occasions can be applied very versatile. The third is a high efficiency, low noise: the use of advanced CAD software, designed by the multi-objective optimization. There are several more specific models, by changing the speed, angle and leaf-type methods, the expansion of the range of performance parameters to meet the needs of different conditions of use, to the fan with the system area with, in order to facilitate energy saving and noise reduction. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Project location without power ventilators should be installed near the roof line, positioning, waterproof substrate rests on the roof, and side edges of the substrate tilt metal plate embedded in the gap under the roof of the Rio 50 ~ 100mm (backplane follow Alice fold 10 ~ 20mm) on the pliers. Cutting the hole to the hole waterproof substrate as a model, draw the outline of the hole plant roof natural ventilation plant, and then complete the hole in the roof cutter cutting. And trim polished edges. With a sharp blade to cut cotton insulation shaped by the meter, after removing part of the insulation cotton, cotton insulation and then aluminum foil insulation between the steel and cotton stuffed. Stick waterproof clay with natural ventilation without power manufacturers, the waterproof silicone, waterproof clay paste with water at the junction Cham board and roof cover. Complete both sides of the top of the peak, labeled waterproof clay belt, and in between the plug and the color plates marked with waterproof silicone, torn cardboard top. Fixed waterproof substrate, with at least 10 self-tapping screws or pop rivets waterproof board is attached to the roof. Installing variable angle tube neck, will change the angle of the neck is mounted on a substrate, the rotation angle of the neck becomes rotatable portion, opposite 90 degree angle adjustment through a level, so that the level of variable angle above the neck. The vertical displacement of the rotation angle of the neck after the adjustment is completed with crayons scribe mark and become part of the angle between the neck and the substrate. The four support arms card turbine head into the reserve in the trench, and then four aluminum pop rivets or screws fixed to the turbine head variable angle tube neck. At least four blind rivets with the fan mounted on the floor, check the screw is solid rivets. Retesting turbine head rotation is smooth and sometimes due to the transport or installation process, the turbine head and squeezed slightly deformed. Slightly adjusted by hand. The last four weeks in the plug marked with waterproof silicone and substrate, no power hood installation is complete.
