①正在隧道风机发动事先，应审查叶轮径向间隙能否匀称，叶片装置立场能否分歧，并确保隧道风机外部和左近没有异物。隧道风机设有防罩子，隧道风机封闭前必需将防罩子装上，并看其叶轮运行位置与壳子上的标记能否分歧。

① Before starting the tunnel fan, check whether the radial clearance of the impeller is symmetrical and whether the position of the blade device is different, and ensure that there are no foreign matters outside and near the tunnel fan. The tunnel fan is equipped with an anti cover. Before the tunnel fan is closed, the anti cover must be installed to see whether the running position of the impeller is different from the mark on the shell.

②隧道风机应正在规则的工况区内运转，偏偏离运转区会使直流电耗费增大，以至延长隧道风机运用寿数。

② The tunnel fan should be operating in the regular working condition area. Being away from the operating area will increase the DC power consumption and prolong the service life of the tunnel fan.

③运转时如收回异样声响，应予即时停机，审查有否正在弹道内有其硬质杂品碰撞隧道风机叶轮，或者弹道骤然没有测阻塞，或者弹道螺帽松动。

③ In case of abnormal sound during operation, it shall be shut down immediately to review whether there are hard sundries colliding with the tunnel fan impeller in the trajectory, or the trajectory is suddenly not blocked, or the ballistic nut is loose.

④隧道风机在启动前应该准备什么?双速隧道风机试工时，应先起动低速，并审查缭绕位置能否准确;起动高速时必需待隧道风机运动后再起，以防高速反向缭绕，惹起电门跳闸及发电机受损。试工今人数没有少于两人，一人掌握电源，一人视察隧道风机运行状况，发觉异样景象即时停机审查;率先审查缭绕位置能否准确;隧道风机进程中，应审查各相运行直流电能否失调、直流电能否超越额外直流电;若有没有畸形景象，应中止审查。

④ What should be prepared before the tunnel fan is started? During the commissioning of two speed tunnel fan, start the low speed first and check whether the winding position is accurate; When starting the high-speed, it must wait until the tunnel fan moves, so as to prevent the high-speed reverse winding, causing switch tripping and generator damage. There are no less than two people in the trial work today. One person controls the power supply, and the other person inspects the operation of the tunnel fan. If he finds something strange, he will stop the machine for review immediately; Take the lead in reviewing whether the winding position is accurate; During the process of tunnel fan, check whether the DC power of each phase can be out of balance and whether the DC power can exceed the additional DC power; If there is no deformity, the review shall be suspended.

⑤陕西隧道风机 答应全压起动或者降压起动，但应留意，全压起动时的直流电为5~7倍的额外直流电，降压起动转距与电压平方成反比，当电网定量有余时，应采纳降压起动。

⑤ Shaanxi tunnel fan allows full voltage starting or step-down starting, but it should be noted that the DC during full voltage starting is 5 ~ 7 times of additional DC, and the step-down starting torque is inversely proportional to the square of voltage. Step-down starting should be adopted when the power grid has enough quantitative surplus.

⑥若运转直流电超越其额外直流电，应审查供应隧道风机的电压能否畸形。隧道风机到达畸形转速时，应检测陕西隧道风机各相输出直流电能否畸形，隧道风机的运转直流电没有能超越其额外直流电。

⑥ If the operating DC exceeds its additional DC, the voltage supplied to the tunnel fan shall be reviewed for abnormalities. When the tunnel fan reaches the abnormal speed, check whether the DC output of each phase of Shaanxi tunnel fan is abnormal, and the operating DC of tunnel fan can not exceed its additional DC.
