The construction, maintenance and installation of ventilation pipes need to be carried out according to the technical requirements. Many people do not understand, these need to strictly abide by the operating specifications. Let's follow Xiao Bian.

通風管道需要嚴格遵守的操作規(guī)范：

The operation specification of ventilation pipe should be strictly observed:

高速運行時，風機和管道應安裝穩(wěn)定。嚴禁安裝在室外。該場地需要配備消防設備。啟動前進行檢查，確保通風機與管道的連接符合要求，運行平穩(wěn)，包括電流過載繼電器保護裝置在內(nèi)的電氣元件在啟動前已完成。

During high-speed operation, the fan and pipeline shall be installed stably. Installation outdoors is strictly prohibited. The site needs to be equipped with fire fighting equipment. Check before starting to ensure that the connection between the fan and the pipe meets the requirements and runs smoothly. The electrical components including the current overload relay protection device have been completed before starting.

風管接頭應嚴格。不同直徑的風管不得混用。其出風口應距工作面6-10米。該裝置不得妨礙行人和車輛通行。架空安裝時，支點和懸掛應牢固可靠。應注意防止隧 道工作面附近的管道爆 破。

The air duct joint shall be strictly sealed. Air ducts of different diameters shall not be mixed. The air outlet should be 6-10m away from the working face. The device shall not obstruct the passage of pedestrians and vehicles. During overhead installation, the fulcrum and suspension shall be firm and reliable. Attention should be paid to prevent pipe blasting near tunnel working face.

運行期間不允許進行維護，只能在從風道返回的空氣消失后進行。在運行過程中，當電機溫度上升到要求以上時，應停止電機冷 卻。

Maintenance is not allowed during operation, only after the return air from the air duct disappears. During operation, when the motor temperature rises above the requirements, the motor cooling should be stopped.
