The following aspects should be paid attention to when starting ventilation equipment:

　　1、啟動前應將風機進口調理風門嚴禁關閉，避免操作錯誤，帶負載啟動;

　　1. Before start-up, the inlet air conditioning valve of the fan should be strictly closed to avoid misoperation and start with load.

　　2、電流表指示恢復到空載電流后，可調理風門開度在恰當的位置;

　　2. After the ammeter indication is restored to the no-load current, the adjustable throttle opening is in the proper position.

　　3、啟動時因啟動風機后疾速停機，判別風機能否有異常現象，如發現風機有異常果斷中止運用，檢查掃除毛病前方能正常啟動;

　　3. When starting, the blower stops quickly after starting, so as to judge whether the blower can have abnormal phenomena. If the blower is found to have abnormal and decisive discontinuation of operation, check that the blower can start normally before cleaning up the defect.

　　4、檢查軸承的光滑油位能否正常、冷卻水管供水狀況、聯軸器能否完好、檢修孔門能否封鎖;

　　4. Check whether the lubricating oil level of the bearing is normal, the water supply condition of the cooling water pipe, whether the coupling is in good condition, whether the repair hole door can be blocked;

　　5 、留意啟動的時間以及空載電流能否正常;

　　5. Pay attention to the start-up time and whether the no-load current is normal.

　　6、通風設備運轉檢查有沒有異常;

　　6. Ventilation equipment operation inspection is abnormal;

　　7、為防止新裝置的風機裝置時沒清算潔凈風機內部的雜質，啟動風機后疾速停機，判別風機能否有異常現象，如發現風機有異常果斷中止運用，檢查掃除毛病前方能正常啟動。

　　7. In order to prevent the impurities in the clean fan from being cleared when the fan device of the new device is installed, it is necessary to stop the fan quickly after starting the fan, and to judge whether the fan can have abnormal phenomena. If the fan is found to have abnormal and decisive discontinuation of operation, it is necessary to check the normal start-up before cleaning the fault.

　　通風管道進程的5大關鍵所在：

　　Five key points in the process of ventilation pipeline are as follows:

　　風管：采用金屬、非金屬薄板或其他資料制造而成，用于空氣流通的管道。

　　Air duct: A pipe made of metal, non-metal sheet or other materials for air circulation.

　　風道：采用混凝土、磚等建筑資料砌筑而成，用于空氣流通的通道。

　　Wind Channel: It is made of concrete, brick and other building materials and is used for air passage.

　　通風工程：送風、排風、除塵、氣力保送以及防、排煙系統工程的統稱。

　　Ventilation engineering: general name of supply air, exhaust air, dust removal, pneumatic delivery and smoke prevention and exhaust system engineering.

　　咬口：金屬薄板邊緣彎曲成一定外形，用于互相固定銜接的結構。

　　Bite: The edges of metal sheets are bent to form a certain shape, which is used to fix and connect each other.

　　空調工程：空氣調理、空氣凈化與干凈空調系統的總稱。

　　Air conditioning engineering: general term for air conditioning, air purification and clean air conditioning systems.
