With the continuous increase of service time, the processing of galvanized and welded ventilation pipes can greatly extend the service life of the air pipes. There will be a lot of impurities in the air pipes. These impurities will be stored in the pipes for a long time, which will accelerate the oil condensation during the work. The temperature is too high, which will cause damage to the air valves, hydraulic and other components, and have a great impact on the normal work.
The poor processing and sealing performance of galvanized ventilation ducts is a serious problem in the air duct installation project, which has a bad impact on the project acceptance. The amount of air leakage of galvanized ventilation ducts is too large, which will cause vibration noise, energy loss and affect the air quality after the ventilation system works. If it is used for waste gas treatment, it is very likely to present toxic gas leakage.
Analysis of the reasons for poor sealing of galvanized ventilation ducts: improper riveting method leads to poor riveting, and flange sealing gasket protrudes into the air duct; The amount of turning over is not enough, and the contact area between the sealing gasket and the flange is reduced, which affects the tightness between flanges; The four corners of the air duct flange are cracked or the four corners are not closely seamed; Flange connecting bolts are loose and not tight;
Measures and countermeasures for poor sealing of air duct processing: the flanging of air duct on the flange shall be checked for air duct prefabrication, which shall be flat and close to the flange, and the width shall not be less than 6mm. The cracks at the four corners of the flanging shall be caulked with sealant, and the four corners shall not show gaps to avoid air leakage. The device mainly checks whether the sealing gasket protrudes into the air duct, whether the connecting bolts are loose, whether the pipe connecting fittings such as elbows, reducers, square and round joints have light leaks, and poor sealing of the ventilation pipe is the primary indicator of the engineering device. Based on the above reasons, relevant countermeasures are proposed to reduce the appearance of quality problems and ensure the quality of the project.
在大型建筑物中，例如運動場館，空氣分配器通常用作空氣出口。 常用的空氣噴射器通風管道包括矩形通風孔和旋轉通風孔。 前者適用于風速不大且空氣分布要求均勻的零件。 后一種類型的風口能夠繞軸線恣意旋轉，而且能夠通過風口的導向葉片調理氣流出口的方向。 該空氣噴射器適用于非固定式本地供氣系統。
In large buildings, such as sports venues, air distributors are usually used as air outlets. Commonly used air ejector ventilation ducts include rectangular vents and rotary vents. The former is applicable to parts with small wind speed and uniform air distribution requirements. The latter type of tuyere can freely rotate around the axis, and can adjust the direction of the air flow outlet through the guide vane of the tuyere. The air injector is applicable to non fixed local air supply system.
