Tunnel jet fan
Tunnel Jet Fan (TVF)-This is a double reversible large and medium axial fan, which is usually located in the tunnel ventilation room on both sides of the subway station, and is used to distance the tunnel ventilation system software. The orientation of the cyclone is from the fan blades to the motor, and the gas is discharged directly from the subway station; the reverse is the big reversal.
Because of the urgency of time, the creator is not the authoritative expert in this field, but only does some simple work and looks forward to assisting the questioner. Based on the current information found by the creator, it will be necessary to check the condition of the fan interlocking shock absorber. Because the commissioning of the tunnel jet fan is very strict:
When the electric fan is turned on, the interlocked intake valve of the commissioning fan should be opened according to the commissioning regulations of the tunnel jet fan, and other relevant intake valves should be set to relative conditions. For the first start, just start the light-emitting mode from the local control cabinet. Press the power button of the switch, and then immediately press the end button to check whether the opening sound and vibration of the fan are normal. Press and hold the end button until the air pressure decreases, open the brake air chamber door to check the brake of the electric fan, and make sure that some abnormalities such as the rotation of the electric fan and no friction of the rolling bearings can be fully started. When the electric fan is fully started and exceeds all normal rates, check whether the vibration of the electric fan is normal, and whether the rolling bearing temperature, output power, working voltage and current of the tunnel jet fan motor are normal. If you find that the anesthesia electromechanical flow exceeds the rated voltage of the tunnel jet fan motor, the rolling bearing temperature rises, strong impact and vibration, immediately terminate and check to clear common faults. The anesthesia machine checks the rolling bearing temperature according to the gearbox and motor bearing temperature alarm system. Under normal circumstances, the ambient temperature of the motor cannot be increased by about 80 ° C, and the temperature of the rolling bearing cannot be increased by about 40 ° C. Wait for everything to work normally for 5 minutes. After no problem, debug again.
