stay Ventilation pipe construction In the process, if the correct construction method is not paid attention to, the consequences will be more serious. Therefore, it is very important to discuss the correct operation process in the construction process. about Ventilation duct Common problems during installation are briefly analyzed below.
The above is all the contents of the common problems during the installation of the ventilation duct. Thank you for your patience. Friends who need help can come to our company for consultation.
(1) For thick steel plate air duct transporting flammable, combustible and explosive vapor, jumper wire shall be installed at the connecting flange of air duct and connected with electrostatic induction grounding construction network.
(2) Before connecting the air duct with the dust remover equipment, heating equipment, etc., the prefabricated components and installation shall be carried out according to the engineering drawings of the detailed mapping project after the construction equipment is completed.
(3) When installing the air duct, the air inlet and air inlet should be provided with the hole edge at the time of prefabricated components of the air duct. If it is necessary to open the air outlet on the installed air duct, its connection should be tight.
(4) When transporting steam containing condensed water or high moisture content, its level pipe should be set with a gradient below and connected with a drainage pipe at the bottom point. When installing, the bottom of the air duct is not suitable for vertical joints, and the joints at the bottom should be sealed.
(5) When the ventilation duct is connected with the centrifugal fan, a soft joint shall be added at the fresh air inlet and outlet, and the cross section specification of the soft joint shall be consistent with the inlet and outlet of the centrifugal fan. The hose connector can generally use white canvas, artificial leather and other raw materials. The length of the plastic hose should not be less than 200, and the tightness should be appropriate. The soft plastic hose can buffer the vibration of the centrifugal fan.
