If the correct installation method is not paid attention to during the processing and installation of ventilation pipes, the consequences will be more serious. Therefore, it is very important to study the correct operation process during installation. The five key points of Shandong ventilation pipe processing and installation are explained in detail.
(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 device network.
(2) Before connecting the air duct with the dust remover equipment and the heating equipment, the prefabricated components and installation shall be carried out according to the engineering drawings of the specific mapping project after the installation of the equipment.
(3) During the installation of the air duct, the air inlet and outlet should be provided with the hole edge at the time of prefabricated components of the air duct. If the air outlet needs to be opened on the air duct after installation, its connection should be tight.
(4) When transporting steam containing condensed water or large moisture content, its horizontal pipeline should be set with a gradient and connected with a drainage pipe at the bottom. During installation, the bottom of the air duct is not suitable for vertical joints, and the joints at the bottom shall 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 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.
The above is all about the five key points for the processing and installation of ventilation ducts. Thank you for your patience. Friends in need can come to our company http://www.jnqsg.com consulting service
