通風管道的材料比較多，比如鋼板風管、玻璃鋼通風管道、復合材料通風管道、塑料通風管道、不銹鋼通風管、單面彩鋼通風管等等。
There are many materials for ventilation pipes, such as steel plate ventilation pipes, glass fiber reinforced plastic ventilation pipes, composite material ventilation pipes, plastic ventilation pipes, stainless steel ventilation pipes, single-sided color steel ventilation pipes, etc.
按用途上來看，通風管可以分為工業排風通風管道、凈化系統通風管道、空調通風管道、瓦斯通風管道等等。
According to the use, the ventilation pipe can be divided into industrial exhaust ventilation pipe, purification system ventilation pipe, air conditioning ventilation pipe, gas ventilation pipe and so on.
通風管道尺寸的計算方法是：風管的橫截面積乘以風管的風速再乘以3600，計算出來的結構就是通風管道的尺寸了
The calculation method of ventilation duct size is: the cross-sectional area of the air duct times the wind speed of the air duct and then times 3600. The calculated structure is the size of the ventilation duct
風管的風速好不要超過15米每秒，好的風速就是8到12米每秒為好。
The wind speed of the air duct should not exceed 15 meters per second, and the good wind speed is 8 to 12 meters per second.
通風管道安裝時要注意安全，如裝修材料、尖角物品、小金屬配件猶其是釘子、廢置木板上是否有釘子、高空作業裝備的配置、穩固天花板工程打好膨脹螺絲，多打一點以防萬一等等問題
Pay attention to safety during the installation of ventilation pipes, such as decoration materials, sharp objects, small metal fittings (especially nails), whether there are nails on the waste wood, the configuration of high-altitude operation equipment, the fixing of ceiling works, the expansion screws, and the like
像是燃氣通風管道安裝、廚房通風管道安裝、消防通風管道安裝、空調通風管道安裝等方面大部分的都涉及高空作業。
For example, gas ventilation pipe installation, kitchen ventilation pipe installation, fire ventilation pipe installation, air conditioning ventilation pipe installation, etc. most of them involve aerial work.
通風管安裝主要涉及的領域有廠房通風、廚房排煙、醫院、寫字樓、酒店、商場、地下車庫等通風，換氣，排煙及污氣處理等環保設施。
The field of ventilation pipe installation mainly involves plant ventilation, kitchen smoke exhaust, hospital, office building, hotel, shopping mall, underground garage and other environmental protection facilities such as ventilation, ventilation, smoke exhaust and sewage gas treatment.
The above is the detailed introduction of the kitchen smoke exhaust hood of Jinan hotel. I hope it will help you. If you have any questions, please contact us. We will provide you with services in a professional manner http://www.xyphw.com
