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. How to control jet fan in operation?

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.

Problems in the use of tunnel fan.

Tunnel fans may generate high temperatures during use, so avoid touching the casing to prevent burns. The motor load current will change with the change of air pressure in the tunnel fan. The overload protection switch suitable for this type should be installed when wiring, and should be used under the condition of rated full load current to avoid motor burning.

The scope of application for continuous operation of tunnel fans should be used within the curve range and not exceed the scope of application. If close closing pressure is required during service, a relief valve should be installed in the line. When the pipe is closed, the pressure relief valve for regulating air in and out automatically opens, thus maintaining the service life of the fan. If the pipe is closed, the temperature of the fan will rise sharply, so continuous operation should be avoided, otherwise deformation or damage may occur.

When the air used is intermittent, the air valve switching mode should be used to operate. Before entering the tunnel fan, dust bag should be used to remove hard objects, dust bag powder, fiber and water droplets. If filters are installed in pipes, to avoid pressure and reduce losses, use large area filters and clean them regularly.

The inside and outside of the tunnel fan should be cleaned regularly to remove dust from the surface. If a large amount of dust is accumulated, its heat dissipation effect will be poor, which may lead to temperature rise, reduced air flow, increased vibration, resulting in failure. Bearings, oil seals and mufflers are consumables, so they have a certain life and need to be replaced regularly. There are blades, shells, metal mesh and so on. Need to be replaced regularly according to the use environment (mainly corrosive airflow, gas-liquid mixture, etc.).

If these possible problems of the tunnel fan can be known before use, they can be solved in time to ensure the normal operation of the tunnel fan in time.
