通風設備啟動前應將風機進口調(diào)節(jié)風門嚴密關閉，以防誤操作，帶負載啟動。山東通風管道加工檢查軸承潤滑油位是否正常、冷卻水管供水情況、聯(lián)軸器是否完好、檢修孔門是否封閉。通風管道的特點：

　　Before the start of ventilation equipment, the fan inlet control air door should be closed tightly to prevent misoperation and start with load. Shandong ventilation pipe processing check lubrication oil level is normal, cooling water supply, the coupling is intact, whether the closed door maintenance. Characteristics of ventilation ducts:

　　1、不銹鋼板風管防腐蝕能力強，內(nèi)壁光滑，同等厚度的不銹鋼板風管的承壓能力和硬度均大于鍍鋅板風管。不銹鋼管的光潔度很好，易于清潔，外觀高檔。但造價也較高。

　　1, stainless steel plate wind pipe corrosion resistance is strong, the inner wall is smooth, the same thickness of stainless steel plate wind pipe pressure capacity and hardness are greater than galvanized pipe duct. Stainless steel tube has a good finish, easy to clean, high appearance. But the cost is also high.

　　2、鍍鋅鋼鈑風管是目前空調(diào)工程、通風排煙系統(tǒng)中應用傳統(tǒng)、廣泛的產(chǎn)品。鍍鋅鋼鈑風管內(nèi)壁光滑、阻力小、氣密性好、承壓強度高。鋼板風管現(xiàn)場制做方便，與土建工程配合緊密，能適合非常復雜的通風工程。鍍鋅鋼板風管造價比不銹鋼板風管要低，用途十分廣泛。目前鍍鋅鋼鈑風管廣泛應用于各種通風、空調(diào)系統(tǒng)中。

　　2, galvanized steel sheet wind pipe is the air conditioning, ventilation and smoke exhaust system in the application of the most traditional and most widely used products. Galvanized steel sheet air pipe inner wall is smooth, small resistance, good air tightness, high bearing strength. The steel pipe air duct is easy to be made on site, and closely matched with civil engineering, so it can be used in very complicated ventilation engineering. The cost of galvanized steel pipe is lower than that of stainless steel plate, so it is widely used. The galvanized steel sheet air pipe is widely used in all kinds of ventilation and air conditioning system.

　　通風風管分圓型和矩形兩種，可根據(jù)廣大用戶的不同需要生產(chǎn)各種型狀、各種規(guī)格型號的風管。

　　There are two kinds of ventilation ducts, round and rectangular, which can produce all kinds of pipes of various shapes and sizes according to the different needs of users.

　　3、制作方式：

　　3, the way of making:

　　制作角鋼(或角鐵)法蘭通風管道和共板法蘭通風管道。角鐵法蘭是傳統(tǒng)的制作方式，制作周期長，效率較低。一般適合小型廠房。

　　Make the angle (or angle) and air duct flange flange ventilation pipe. Angle iron flange is a traditional way of making, long production cycle, low efficiency. Generally suitable for small workshops.
