  通风除尘系统的排风罩、集尘器、风机等主要设备与通风管道连接。为确保通风除尘系统安全有效运行,应做好以下检查工作:
  The main equipment of the ventilation and dust removal system, such as the exhaust hood, dust collector and fan, are connected with the ventilation pipeline. In order to ensure the safe and effective operation of ventilation and dust removal system, the following inspection work should be done well:
  1. 外表面的磨损、腐蚀、凹陷等情况
  1. Wear, corrosion and depression on the outer surface
  目视检查管道外表面状态,重点观察管道支路、管径变化、转弯等流量变化情况。排气管的支管从与排风罩的连接处到合流处进行检查;沿流向检查主管道。确保没有例外:
  Visual inspection of the external surface of the pipeline, focusing on the observation of pipeline branches, pipe diameter changes, turning and other flow changes. The branch pipe of the exhaust pipe is inspected from the connection with the exhaust hood to the confluence; the main pipe is inspected along the flow direction. Ensure that there are no exceptions:
  (一)磨损、腐蚀、凹陷等可能造成漏气的损害;
  (1) Wear, corrosion, depression, etc. may cause air leakage damage;
  (二)可能引起腐蚀的油漆损坏;
  (2) Paint damage that may cause corrosion;
  (3)可能存在增加风阻或积尘的变形。
  (3) There may be deformations that increase wind resistance or dust deposition.
  2. 阀状态
  2. Valve status
  (1)检查流量调节阀的开启和固定状态,确保阀门能够固定在开启处,使设备性能良好。
  (1) Check the opening and fixing state of the flow control valve to ensure that the valve can be fixed at the opening, so that the equipment performance is good.
  (2)对于带开关阀的管路系统,应分别打开或关闭排气罩连接线,并启动局部排气装置。当管道正常打开时,烟被吸入排气罩;当管道关闭时,烟不会被吸入排气罩。
  (2) For pipeline systems with on-off valves, the connection lines of exhaust hood should be opened or closed separately, and the local exhaust devices should be started. When the pipe opens normally, smoke is sucked into the exhaust hood; when the pipe closes, smoke is not sucked into the exhaust hood.

  3.连接位置状态
  3. Connection position status
  (1)检查法兰连接螺栓、螺母和垫圈,确保无损坏、丢失或密封性不均匀。
  (1) Check flange bolts, nuts and gaskets to ensure no damage, loss or uneven sealing.
  (2)启动本机排烟装置,检查与排烟机的连接,确保烟气不被吸入或吹走。
  (2) Start the smoke exhaust device of the machine, check the connection with the smoke exhaust machine, and ensure that the smoke is not sucked into or blown away.
  (3)如果(2)检查不可能,则应听管道连接,以确保没有进气口或泄漏。
  (3) If (2) inspection is not possible, the pipeline connection should be listened to to to ensure that there is no intake or leakage.
  (4)的检验(2)或(3)不能进行,空速管和微压计是用来检测管道的静压通过管道上的孔,以确保之间没有显著差异在管道静压值和设计值。
  (4) Inspection (2) or (3) cannot be carried out. Airspeed tubes and micromanometers are used to detect the static pressure of pipelines passing through the holes in the pipeline to ensure that there is no significant difference between the static pressure values of pipelines and the design values.
  4. 检查孔状态
  4. Check hole status
  (1)检查检查孔部位,确保无损伤、腐蚀、剥落等。
  (1) Check the location of the inspection hole to ensure no damage, corrosion, peeling, etc.
  (2)检查检查孔的开闭状态,确保开关灵活,密封性能好。
  (2) Check the opening and closing state of the inspection hole to ensure that the switch is flexible and the sealing performance is good.
  (3)检查带烟雾发生器的密封垫区域,确保没有烟雾被吸入或吹走。
  (3) Check the sealing area with the smoke generator to ensure that no smoke is inhaled or blown away.
