专注通风管道加工·排烟罩

　　通风控制系统可根据不同的情况采用不同的控制方式，如，单台通风设备定风量通风控制系统、多台通风设备变频控制系统、多台通风设备变频+变风量通风控制系统。

　　The ventilation control system according to different conditions by using different control methods, such as single ventilation control ventilation system, a control system of ventilation equipment, ventilation equipment of multiple frequency conversion and variable air volume control ventilation system.

　　对于一般的普通建筑，若室内排出的气体没有腐蚀性，通风管道可以采用镀锌钢板，对于产生有腐蚀性气体的实验室，风管应采用耐腐蚀材料的PVC风管或玻璃钢风管。

　　For ordinary buildings, if the gas discharged from the interior is not corrosive, ventilation pipe can be used for producing galvanized steel, corrosive gas laboratory, wind pipe should be made of corrosion resistant materials PVC duct or glass steel duct.

　　在一般的实验室通风工程，室内大多采用PVC风管、室外采用玻璃钢风管。对于室内层高不足的实验室或采用大型风管的实验室，一般采用矩形风管，以便与现场空间匹配，在满足风管要求的前提下，尽量减小风管占用空间。

　　In general laboratory ventilation engineering, most indoor use of PVC duct, outdoor glass fiber reinforced plastic pipe. The height is insufficient for the indoor laboratory or by large duct laboratory, generally use the rectangular duct, in order to match the scene space, to meet the requirements of the wind pipe under the premise, try to reduce wind pipe space.

　　圆形风管采用插件连接，矩形风管采用法兰方式连接，根据实际情况也可采用插件方式连接。

　　The round air pipe is connected by a plug-in unit, and the rectangular air pipe is connected by a flange, and the plug-in can be connected according to the actual situation.

　　风机主要有轴流风机、斜流风机、离心风机。轴流风机、斜流风机适用于风压小、管路短的通风系统，如，直接排窗外或墙外的通风系统，简称：直排;玻璃钢离心风机适用于管路长的通风系统，如，通过风管井或外墙接管排屋顶，简称：屋顶排放。

　　Main fans are axial fans, diagonal fans and centrifugal fans. Axial flow fan, oblique flow fan for air pressure is small, short pipeline ventilation system, such as, referred to as the ventilation system, discharged directly to the window or wall: straight row; glass steel centrifugal fan for ventilation system, such as long pipeline, through the air tube or the wall over the row to the roof, Jane said: roof emissions.

　　我们愿以佳的服务意识，迎接八方来客，诚恳与国内外各界朋友精诚合作，共创美好的前程。欢迎大家前来参观洽谈!

　　We would like to serve the eight guests with the best sense of service, and sincerely cooperate with friends from all walks of life at home and abroad for a better future. Welcome to visit and negotiate!
