As the industry develops faster and faster, the application of turbine hard fast doors is getting more and more affirmation from everyone. Many factories, workshops, passages, storage doors and other places will use turbine hard fast doors. But as more and more places and people are used, more and more problems arise. In many cases, problems are caused by users who are not familiar with the operating procedures and irregular use, but the product has also experienced many failures during the growth of the service life. We will analyze the common faults and solutions of turbine hard fast doors today.

Turbine hard fast doors are connected in series with multi-joint movable doors. In a fixed slideway, the upper and lower doors rotate around the reel above the door. Safety configuration and sealing performance are particularly important.


(1) Troubleshoot the cause of the unstable door panel of the turbine hard fast door
1. The brake pads of the turbine hard fast door have oil stains. Clean with gasoline.
2. The compression spring force is reduced. Replace the spring.
3. The solenoid of the turbine hard fast door is not installed properly. re-install.

Use turbine hard fast door

(2) Troubleshoot the reason why the hand zipper of the turbine hard fast door cannot be pulled
1. The ring chain blocks the cross groove. Straighten out the chain.
2. The electromagnet fasteners are loose.


(3) Investigation of the cause of the failure of the self-weight drop of the turbine hard fast door
1. The manual pull rod of the turbine hard fast door is deformed. Replace the manual lever.
2. The gap between the manual pull rod and the washer is large. Reduce the gap.
3. The lubrication of the gearbox motor of the turbine hard fast door fails. Change the grease.


(4) Troubleshoot the reason why the motor of the turbine hard fast door does not start
1. The circuit of the turbine hard fast door is disconnected, check the wire.
2. The running capacitor of the turbine hard fast door is damaged. Replace the running capacitor.
3. The overheating protection fails. Replace the overheat protector.
4. The brake is stuck. Manually pull the chain a few times.
5. The normally closed contact of the limit switch of the turbine hard fast door does not work. Polish the contact or replace the limit switch.
6. The relay coil is broken or oxidized, stained, replace the relay or polish the contacts.
7. The continuous operation time of the turbine hard fast door is too long, and the thermal protection is disconnected. The temperature of the motor can be reduced.
8. The bridge rectifier is broken or the electromagnetic coil is broken, and the brake is stuck. Replace the bridge rectifier or the electromagnetic coil.


The above are the common faults and solutions of turbine hard fast doors. The application of turbine hard fast doors is wide. The turbine hard fast door is a kind of industrial equipment configuration facility with high speed, strong sealing, energy saving and environmental protection. There are many occasions to use turbine hard fast doors, such as factories, workshops, clean rooms, logistics channels, fast buffer rooms and so on.
