专注通风管道加工·排烟罩

　　通风设备启动前应将风机进口调节风门严密关闭，以防误操作，带负载启动。山东通风管道加工检查轴承润滑油位是否正常、冷却水管供水情况、联轴器是否完好、检修孔门是否封闭。通风管道的特点：

　　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、不锈钢板风管防腐蚀能力强，内壁光滑，同等厚度的不锈钢板风管的承压能力和硬度均大于镀锌板风管。不锈钢管的光洁度很好，易于清洁，外观高档。但造价也较高。

　　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、镀锌钢钣风管是目前空调工程、通风排烟系统中应用传统、广泛的产品。镀锌钢钣风管内壁光滑、阻力小、气密性好、承压强度高。钢板风管现场制做方便，与土建工程配合紧密，能适合非常复杂的通风工程。镀锌钢板风管造价比不锈钢板风管要低，用途十分广泛。目前镀锌钢钣风管广泛应用于各种通风、空调系统中。

　　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.

　　通风风管分圆型和矩形两种，可根据广大用户的不同需要生产各种型状、各种规格型号的风管。

　　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:

　　制作角钢(或角铁)法兰通风管道和共板法兰通风管道。角铁法兰是传统的制作方式，制作周期长，效率较低。一般适合小型厂房。

　　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.
