How to control tunnel jet fan in operation?
There are many kinds of fans. As long as there is an environment that needs ventilation, there is a fan. Of course, according to the different environment, the fan used is also different. Take the jet fan for example, this fan is the fan for ventilation in the tunnel, which is used during tunnel construction. When we use this fan, we do not put it there and then turn on the switch and leave it alone. In the middle, we need to carry out a control. How to control the jet fan when it is running?
1. Control stage of electric control room
The catering, shielding and controlling components of environmental control facilities are fully installed in the electric control cabinet, and the jet fan can be controlled by clicking in the electric control cabinet, and the various forms of the jet fan can be displayed.
2. Vehicle control room control stage
We will be in electric control cabinet intelligent generator motor cover installation amount of jet fan form collected through high voltage network open to the computer control room balcony, and building facilities initiative in spare gateway to stop dual channel redundant communication, also can synthesize BAS spare set to compile a good master notice by high pressure jet fan gateway communication after indirect issued to the underlying infrastructure.

3. Vehicle control room control stage
In an emergency situation, a number of ports can also be indirectly arranged by telephone to implement echo environmental control in the form of the analysis of the backup disk of the car control room. The cover of electric effect is often linked with its mastery form, that is, there is control in the cover, and there is cover in the mastery. With the stagnation of industrial control skills, the form of the control and cover generator is breaking the contactor, thermal replacement or road jacker control and cover of the conservative form, the control core can be linked to two or more port environmental control facilities to participate in the condition of control. BAS fragmentary gateway can upload the indirect network communication of jet fan shape quantity to the master core, and can also send the notification to the bottom layer indirectly through the communication network.
4. Local control priority
The master knob box is being installed beside the jet fan. For the jet fan to stop mastering and show various forms, it is improper to repair and protect the general operation of the fan.
How to control jet fan in operation? In the use of jet fans, it is not only necessary to control, but also to carry out a protection. If there are external reasons that lead to the failure of the fan, it is also a loss.
