Rapid shutter door is through the rapid shutter door frequency converter and drop, shorten the material and the pedestrian's entrance and exit time and design of automation equipment, in foreign factories have been popular, and the domestic rapid shutter door industry started late, all aspects of technology and supporting is not very perfect. In order to improve the quality of products and ensure the safety of the factory, rapid rolling door production and application will be an inevitable trend.

Quick shutter door fault and maintenance method:

1. Loud noise

Fast door running noise, the main reason may be fast shutter door inverter overheating.

Treatment: check whether the installation space of the quick door inverter is ventilated and whether the cooling fan at the bottom is running normally.

2. Stop lifting

Shutter door suspended operation, the main possibility is circuit disconnection or capacitance damage.

Repair method: check the circuit is normal, replace the running capacitor and overheat protector.

Falling out of control

Fast shutter doors can not rely on their own weight normal slide, the main reason for the chain stuck or manual rod deformation.

Treatment: add lubricating oil to the ring chain, replace the manual rod, etc.

In order to ensure the normal operation of the rapid shutter door, reduce the fault, should strengthen the maintenance mechanism, regular maintenance, to prevent accidents. A good way to prevent the temporary interruption of the fast door is equipped with a special frequency converter for the fast shutter door, through a variety of software and hardware protection measures to ensure the normal operation of the fast door.
