1.1KW1.5KWExdIIBT4防爆璧式崗位式風機
一、采用BT35防爆軸流風機,需在出風口中連接管道時,必須考慮與管道連接方式,以減少通風機的動壓在接管段因擴散
而造成的損失。
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.當管道 直徑與通風機桶相等時,管道的擴散損失可忽略不計(如圖1);
2.當 ≤1.5時而管道長度小于管內徑5~8倍時,可不加擴散器(如圖2);
3.當1.5≤ <2.5時,管道與通風機應安裝如圖所示型式之擴散器(如圖3);
4.當 >2.5時,管道與通風機應安裝如圖所示型式之擴散器(如圖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.nd 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).
