說到檢查鍍鋅風管漏風量這個常識，咱們大家要有個意識就是這是關聯到全部鍍鋅風管是否更有效的被利用的要害性因素。所以說咱們一定要對其進行良好的測試后再對其進行利用。特別須要留神到的是咱們在丈量該鍍鋅風管的漏風量的時候在晚上進行，保障四處環境較暗，將100W帶維護罩的低壓照明燈置于風管內側或外側，沿檢測部位與接縫作緩慢挪動，在另一側進行察看，當發明有光芒射出，則說明查到明顯漏風部位，并作好記錄。
Speaking of the common sense of checking the air leakage rate of galvanized air ducts, we should first be aware that this is a crucial factor related to whether all galvanized air ducts can be used more effectively. So we must test it well before using it. It is particularly important to note that we measure the air leakage of the galvanized air duct at night to ensure that the environment around is dark. Place the 100W low-voltage lighting lamp with maintenance cover on the inside or outside of the air duct, move slowly along the detection part and joint, and observe on the other side. If there is light emitting, it means that the obvious air leakage part is found and recorded.
鍍鋅風管市場上按材質個別分為三類：鍍鋅鍍鋅風管、不銹鋼鍍鋅風管以及復合鍍鋅風管。其中，不銹鋼風管品質較好，實用性強，但高。
The galvanized air duct market is divided into three categories by material: galvanized air duct, stainless steel galvanized air duct and composite galvanized air duct. Among them, the stainless steel air duct has good quality and strong practicability, but its price is high.
市場暢廣的鍍鋅風管是鍍鋅板的。鍍鋅板鍍鋅風管，基本是不銹鋼鍍鋅風管的特點，然而只有不銹鋼風管的三分之二甚更低。復合鍍鋅風管個別利用在外界環境較為個別，對風管請求不太高的場合。
The galvanized air duct with smooth market is made of galvanized sheet. Galvanized sheet galvanized air duct is basically the feature of stainless steel galvanized air duct, but the price is only two-thirds of that of stainless steel air duct or even lower. Composite galvanized air duct is used individually in the external environment where the requirements for air duct are not high.
鍍鋅風管在很多排風體系中都有利用。競賽大廳的空調送風管為雙層保溫型圓形鍍鋅風管1400mm及1600mm,共計12條，送風方法采取126個630mm球形噴口從四處向館內送風，對此采取了鍍鋅風管整體吊裝技巧。
Galvanized air duct is used in many exhaust systems. The air conditioning air supply pipes in the competition hall are 1400mm and 1600mm double insulated circular galvanized air pipes, totaling 12. The air supply method is to use 126 630mm spherical nozzles to supply air from four places to the hall. For this, the overall hoisting technique of galvanized air pipes is adopted.
