(2)风道装置时,进、出风日宜在风道预制时开出洞口,如需在装置结束的风道上现开风口,其接口处应严密。
(2) air duct device, into and out of the hole should be opened in the air duct prefabrication, for in the end of the air duct device in air, the interface should be tight.
(3)对运送易燃、易爆气体的钢板风道,在风道衔接法兰处应装置跨接线,并与静电接地网衔接。
(3) for flammable and explosive gas, the steel plate air duct should be connected in the connection flange at the connecting flange of the wind tunnel and connected with the electrostatic grounding grid.

(4) when the double hanger bracket is in position in the air duct, the horizontal load should be ensured, the hanger does not change, and the double hanger is subjected to uniform force.
(5)当运送含凝结水或含湿量较大的气体时,其水平管道宜设有斜度,并在低点处接排水管。装置时风道底部不宜呈现纵向接缝,对底部有接缝处应进行密封处理。
(5) when transporting a gas containing condensed water or a large amount of moisture, the horizontal pipe is inclined to be inclined and the drainage pipe is placed at the low point. The longitudinal joint should not be presented at the bottom of the air duct, and the seams at the bottom should be sealed.
(6)当水平风道高度在2m以上时,装置人员应系安全带。脚手架或移动式支架上的跳板应固定好,跳板宽度应契合安全标准,在脚手架上的装置人员宜携东西袋,避免东西或电钻等物坠落伤人。
(6) when the height of the horizontal air duct is above 2m, the installation staff should be a seat belt. The springboard on scaffold or mobile bracket should be fixed. The springboard width should conform to the safety standard. The personnel on scaffolding devices should carry things and bags to avoid falling objects or electric drills and hurting people.

(7)当风管与风机衔接时,应在进出风口处加软接头,其软接头的断面尺寸应与风机进出风口一致。软管接头一般可选用帆布、人造革等资料,软管长度不宜小于200,松紧度应适宜,柔性软管可缓冲风机的振荡。
(7) when the wind pipe is connected with the fan, the soft joint should be added at the inlet and outlet. The section size of the soft joint should be the same as the fan inlet and outlet. Canvas, artificial leather and so on, the hose length should not be less than 200, the tightness should be suitable, flexible hose can buffer the oscillation of the fan.
