The ventilation duct equipment is made of stainless steel, which can improve the service life of the equipment, make cleaning convenient and simple, and is conducive to rapid work. The main thing is that the technical parameters such as air volume and speed of the equipment need to meet the application requirements and regulations of the entire project. If the conditions are slightly better, the warehouse can choose equipment ventilation ducts, which not only solves the problem but also better improves the warehouse environment and is more conducive to material storage. You can also choose equipment ventilation fan or equipment ventilation electric fan, but it should be noted that the fan installed at the ventilation outlet is turned off after work.

如果長時間旋轉(zhuǎn)，轉(zhuǎn)軸過熱會引起火災(zāi)，造成倉庫重大事故。常用的塑料通風(fēng)管采用硬聚氯乙烯塑料板。由于其良好的化學(xué)穩(wěn)定性，常用于運(yùn)輸腐蝕性氣體。加工硬聚氯乙烯風(fēng)管及附件時，與金屬板風(fēng)管在展開劃線方面相同，其他方面差別很大。通風(fēng)管道設(shè)備結(jié)束后，板與板的連接采用熱風(fēng)塑料焊接，風(fēng)管縱縫應(yīng)交鍺設(shè)置，組裝焊接時可考慮圓形風(fēng)管。

If rotated for a long time, overheating of the shaft can cause a fire and cause a major accident in the warehouse. The commonly used plastic ventilation pipes use rigid polyvinyl chloride plastic sheets. Because of its good chemical stability, it is often used to transport corrosive gases. When processing hard polyvinyl chloride air ducts and accessories, they are the same in terms of unfolding and marking as metal sheet air ducts, but there are significant differences in other aspects. After the completion of ventilation duct equipment, hot air plastic welding shall be adopted for the connection between plates, and the longitudinal seam of air duct shall be set with germanium. Circular air duct can be considered during assembly and welding.

通風(fēng)管道的應(yīng)用可以使良好的通風(fēng)，促進(jìn)室內(nèi)空氣循環(huán)，控制氣流速度，什么是通風(fēng)，即排出室內(nèi)或關(guān)閉空間中渾濁的空氣，凈化工廠產(chǎn)生的所有有害物質(zhì)后排出室外，然后將新鮮空氣送入室內(nèi)稀釋空氣中的有害物質(zhì)，滿足人們對空氣的需求。通風(fēng)管道用于無塵車間的凈化，用于制藥或食品無菌車間的空調(diào)處理系統(tǒng)，電子廠和制造業(yè)的凈化;也可用于安裝在空調(diào)中，如大型購物場所、一些豪華辦公樓層和酒店;在工業(yè)生產(chǎn)中，可用于清潔灰塵、清除油煙等排氣設(shè)備、煤礦礦井通風(fēng)系統(tǒng)和煤氣系統(tǒng)。

The application of ventilation ducts can promote good ventilation, promote indoor air circulation, control airflow speed, and what is ventilation? It refers to the removal of turbid air from indoor or closed spaces, purification of all harmful substances generated by the factory, and then discharge them outdoors. Fresh air is then sent into the indoor air to dilute the harmful substances, meeting people's air needs. Ventilation ducts are used for purification in dust-free workshops, air conditioning systems in pharmaceutical or food aseptic workshops, purification in electronic factories and manufacturing industries; It can also be installed in air conditioning, such as large shopping venues, some luxury office floors, and hotels; In industrial production, it can be used for cleaning dust, removing oil fumes and other exhaust equipment, coal mine ventilation systems, and gas systems.
