通风管道的安装和制造
Installation and manufacturing of ventilation ducts
首先,通风管道的安装和制造要做好充分的准备。在安装过程中,还存在一些需要注意的问题。如下所示:
Firstly, adequate preparation should be made for the installation and
manufacturing of ventilation ducts. During the installation process,
there are still some issues that need to be noted. As follows:
1.检查设备是否符合要求,确保排气表面光滑。控制在2mm以内有误差。再次清扫管道,确保其外观干净。留出孔的位置和尺寸。在地面组装风管,可分段组装,用法兰螺栓紧固。螺帽应朝向同一个方向,放在支架上方,借助人工和绳索固定,调整风道的垂直度。
1. Check if the equipment meets the requirements and ensure that the
exhaust surface is smooth. There is an error in controlling within 2mm.
Clean the pipeline again to ensure its clean appearance. Set aside the
position and size of the holes. Assemble the air duct on the ground,
which can be assembled in sections and fastened with flange bolts. The
nut should face in the same direction and be placed above the bracket,
fixed with manual labor and ropes to adjust the verticality of the air
duct.
2.按要求固定,然后固定电线等。管道两端从滚筒上滚出,用铆钉紧固,可满足通风安装要求。
2. Fix as required, and then fix wires, etc. The two ends of the
pipeline are rolled out from the drum and fastened with rivets to meet
the ventilation installation requirements.
3.安装前,应进行以下检查。检查合格后,安装前应填写相关验收资料:风口表面应平整,风机各角应灵活,叶片或插板应平直,内叶片州苗木 保定电动门 保定空压机 化粪池模具 微型蠕动泵 保定强夯 收费岛模具间距应均匀,扩压器膨胀环与调速装置应同轴,轴向间距应均匀,叶片开合度应完整,防空封阀与冲击波的方向不应颠倒。
Before installation, the following checks should be carried out. After
passing the inspection, relevant acceptance materials should be filled
out before installation: the surface of the air outlet should be flat,
the corners of the fan should be flexible, the blades or insert plates
should be straight, the spacing between the inner blades should be
uniform, the expansion ring of the diffuser and the speed control device
should be coaxial, the axial spacing should be uniform, the opening and
closing of the blades should be complete, and the direction of the air
defense sealing valve and the shock wave should not be reversed.
