　　From the perspective of building ventilation system construction, some materials need to be used and installed after air duct treatment. In the process of building acceptance, it also has a great advantage. The characteristics of ventilation effect are updated, and it is noted that at present, the construction technology advantage of the building is more and more obvious, which can be grasped in a new way. Therefore, for this kind of processing technology, it can reach the most perfect standard. Pay attention to the approval of pipeline technology.

　　在通風系統(tǒng)中輸送氣體的管道被稱為風管，它將系統(tǒng)中的各種設備或部件連接成一個整體。為了提高系統(tǒng)的經(jīng)濟性，山東地區(qū)風道內的氣流速度應合理選擇，管道應短而直。風管通常由表面光滑的材料制成，如:薄鋼板、PVC板，有時也用混凝土、磚等材料制成。

　　The pipe conveying gas in the ventilation system is called the air pipe, which connects various equipment or components in the system into a whole. In order to improve the economy of the system, the air velocity in the air duct of Shandong area should be reasonably selected, and the pipeline should be short and straight. Air ducts are usually made of smooth surface materials, such as steel sheet, PVC plate, and sometimes concrete, brick and other materials.

　　作為業(yè)內知名的環(huán)境治理綜合解決方案提供商，在流域治理方面擁有國內外的技術和豐富的運營經(jīng)驗。根據(jù)周圍環(huán)境和生態(tài)湖泊水質特點，山東通風管道及業(yè)主的發(fā)展規(guī)劃，制定了完整的生態(tài)系統(tǒng)建設規(guī)劃，對湖泊水質進行控制和修復。施工團隊憑借豐富的操作經(jīng)驗和嚴格的施工規(guī)范，僅用一個月時間完成了生態(tài)系統(tǒng)主體的施工，并順利通過了初步驗收。目前，湖內及周邊排水區(qū)域水質得到有效改善，山東通風管道服務得到業(yè)主及當?shù)鼐用竦囊恢抡J可。

　　As a well-known comprehensive solution provider of environmental governance in the industry, it has leading professional technology and rich operation experience at home and abroad in Watershed Governance. According to the characteristics of surrounding environment and ecological lake water quality, the development plan of Shandong ventilation pipeline and the owner, a complete ecological system construction plan has been formulated to control and repair the lake water quality. With rich operation experience and strict construction specifications, the construction team completed the construction of the main body of the ecosystem in only one month and successfully passed the preliminary acceptance. At present, the water quality in the lake and surrounding drainage areas has been effectively improved, and the ventilation pipeline service in Shandong Province has been unanimously recognized by the owners and local residents.

　　供氣管道和回氣管道的質量要求存在較大差異。一般來說，供氣管道一般密封良好，山東通風管道材料也很好(一般使用專用鐵管)，與回氣管道不同。干墻、實木、中空塑料板等常用在回風管道中。一般情況下，回風管道存在一定的漏風現(xiàn)象。在管道清洗中，管道泄漏自然會導致吸力顯著降低，這將極大地影響管道清洗的質量。因此，對供氣、回風管道的混合清洗不僅會導致對回風管道的清洗不干凈，還會導致對供氣、回風管道的清洗不干凈。

　　The quality requirements of gas supply pipeline and return pipeline are quite different. Generally speaking, the gas supply pipeline is generally well sealed, and the material of Shandong ventilation pipeline is also very good (special iron pipe is generally used), which is different from the return pipeline. Dry wall, solid wood, hollow plastic board, etc. are often used in return air duct. In general, there is a certain air leakage in the return air pipe. In pipeline cleaning, pipeline leakage will naturally lead to a significant reduction in suction, which will greatly affect the quality of pipeline cleaning. Therefore, the mixed cleaning of air supply and return pipes will not only lead to unclean cleaning of return pipes, but also lead to unclean cleaning of air supply and return pipes.
