通風管道體系作業(yè)噪音—般來源

來源:http://m.heblc.com/     發(fā)布時間:2022-01-10  

風管的顫動。因為風管材料是鍍鋅板或者是金屬材料,在施工時要嚴峻按照施工檜驗標準選擇鋼板厚度和施工工藝,比如風管制作差錯、平直度、風管加固.電扇前后盡量都有5米以上的長度。假定可以增加彎頭數(shù)目也可以下降噪音,風口加裝過濾網(wǎng),噪音操控作用也很好。
Vibration of air duct. Because the air duct material is galvanized sheet or metal material, the steel plate thickness and construction process shall be selected strictly according to the construction inspection standard, such as air duct fabrication error, flatness and air duct reinforcement The front and back of the electric fan shall be more than 5m long as possible. Assuming that the number of elbows can be increased and the noise can be reduced, the air outlet is equipped with a filter screen, and the noise control function is also very good.
風機的動靜。處理方法我們一般可裝消聲器處理
Dynamic and static of fan. Treatment method we can generally install muffler for treatment
風管zhong風的沖突聲。一般在規(guī)劃階段就要考慮噪聲的問題,規(guī)劃操控好管內(nèi)風速,防止風聲嘯叫
Duct zhongthe clash sound of the wind. Generally, the noise problem should be considered in the planning stage, and the wind speed in the pipe should be planned and controlled to prevent wind howling

1操控出風、回風間隔,防止空氣對流時自激表象和小循環(huán)空間。
1. Control the air outlet and return intervals to prevent self-excited appearance and small circulation space during air convection.
2、螺旋風管風機葉輪體系動平衡校調(diào)合理正常正負不大于5絲的高低。
2. The dynamic balance adjustment of spiral duct fan impeller system is reasonable, and the positive and negative are not greater than 5 wires.
3、軟接頭設備標準,防止軟接帆布松垮發(fā)生風阻而形成風噪。
3. Flexible joint equipment standard to prevent wind resistance and wind noise caused by loose flexible joint canvas.
4、懸掛選用趁便繃簧避震專職的連接器,減輕作業(yè)時因扭力發(fā)生的跳動或共頻。
4. The suspension adopts the full-time connector of tension spring shock absorber to reduce the runout or common frequency caused by torque during operation.
5、螺旋風管風道轉角盡量削減
5. The air duct corner of spiral duct shall be reduced as much as possible
