使用 Applications
一、采用BT35防爆轴流风机,需在出风口中连接管道时,必须考虑与管道连接方式,以减少通风机的动压在接管段因扩散
而造成的损失。
When connecting the pipes to the outlet of the BT35 explosion-proof axial flow fan, take account of the connection wayto reduce the losswhich caused by dynamic pressure of ventilator in the a connected pipe.
1.当管道 直径与通风机桶相等时,管道的扩散损失可忽略不计(如图1);
2.当 ≤1.5时而管道长度小于管内径5~8倍时,可不加扩散器(如图2);
3.当1.5≤ <2.5时,管道与通风机应安装如图所示型式之扩散器(如图3);
4.当 >2.5时,管道与通风机应安装如图所示型式之扩散器(如图4)。
1.When the diameter of the pipe is equal to that of ventilator barrel, the lossof diffusion in pipecan be omitted(As shown in fig 1);
2.When ≤1.5and the pipe is 5~8 times shorter than the internal pipediameter,the diffuser can be unset(As shown in fig 2);
3.When 1.5≤ <2.5,the diffuser as shown in the diagram shall be fittedto the pipeand ventilator (As shown in fig 3);
4.When >2.5,the diffuser as shown in the diagram shall be fitted to thepipe andventilator (As shown in fig 4).
