In this way, it will increase the use cycle of the equipment, and the cleaning is simple and simple, which is conducive to the rapid operation. The important point is that the technical parameters such as the air volume, rotation speed, and so on of the equipment reach the requirements of all engineering applications and regulations.

假設條件略微好一點倉庫無妨挑選設備通風管道，不只無妨處理問題，還能改進倉庫環境，更利于物質的貯存。也無妨挑選設備換氣扇或許設備通風電風機，但需注重，通風口裝的風機在下班的時辰關掉，假設光轉動，轉軸過熱起火會導致火災，構成倉庫嚴峻事件。

Assume that the warehouse with slightly better conditions is not only conducive to selecting equipment ventilation pipes, but also to improving the warehouse environment and material storage. It is also no harm to select the equipment ventilator or the equipment ventilation electric fan, but it should be noted that the ventilator installed at the vent is turned off at the time of work. Assuming that the light rotates, the shaft overheats and catches fire, which will lead to a serious event in the warehouse.

常用的塑料通風管道是用硬聚氯乙烯塑料板加工而成。因為它具有較好的化學安穩性，常用來運送有侵蝕性的氣體。硬聚氯乙烯風管及附件進行加工時，與金屬板風管在翻開劃線方面是相同的，其余方面有很大的差異。通風管道設備結束往后，板與板的聯接選用熱風塑料焊接，風管的縱縫應交鍺配備，圓形風管可在組配焊接時研究。

The commonly used plastic ventilation pipe is made of rigid polyvinyl chloride plastic sheet. Because of its good chemical stability, it is often used to transport corrosive gases. Unplasticized polyvinyl chloride air duct and accessories are processed in the same way as metal sheet air duct in terms of opening and scribing, while there are great differences in other aspects. After the completion of the ventilation duct equipment, the connection between the plate and the plate shall be welded with hot-air plastic. The longitudinal seam of the air duct shall be equipped with germanium. The round air duct can be studied during assembly and welding.

通風管道工程平常選用手藝施工，不需求特意的加工設備，因此通風管道工程適宜于家用空調如此的小場所施工。選用復合伙料現場制造巨細通、彎頭號配件也非常簡略，因此施工速度快，且對施工職員的需求也相對下落。

The ventilation duct works are usually constructed by craft, and do not require special processing equipment. Therefore, the ventilation duct works are suitable for construction in such small places as domestic air conditioners. It is also very simple to use composite materials to manufacture large and small fittings and elbow fittings on site, so the construction speed is fast, and the demand for construction staff is relatively low.

其他，通風管道對設備精度的需求也相對較低，這又能夠前進風管的設備速度。通風管道工程界說無妨闡明為：送風、排風、除塵、氣力運送和防、排煙體系工程的總稱。

In addition, the demand for equipment accuracy of ventilation duct is relatively low, which can advance the equipment speed of air duct. The definition of ventilation pipeline engineering is clearly defined as the general term of air supply, exhaust, dust removal, pneumatic transportation and smoke control and exhaust system engineering.
