Electric rolling shutters are very common in today’s society, and they are widely used in interior and exterior doors of buildings. Because of its small space, safety and practicality, it is deeply loved by the public. But how much do you know about it? Today, let Bedi Motor popularize the knowledge about electric rolling gates, and tell you about the maintenance of electric rolling gates, motors and faults.
Common faults and maintenance of electric rolling gate motors
1) The motor does not move or the speed is slow. This fault is generally caused by circuit breakage, motor burnout, stop button not reset, limit switch action, and large load.
Solution: check the circuit and connect it; replace the burnt motor; replace the button or press it several times repeatedly; move the limit switch slider to separate it from the micro switch contact, and adjust the position of the micro switch; check the mechanical part Whether there is jamming, if there is, eliminate the jamming and clear the obstacles.
2) The location and cause of the failure of the control failure: the contact of the relay (contactor) is stuck, the travel micro switch is invalid or the contact piece is deformed, the set screw of the slider is loose, and the screw of the backing board is loose, which makes the backing board shift, causing the The slider or nut cannot move with the screw rod rolling, the limiter transmission gear is damaged, and the up and down keys of the button are stuck.
Solution: Replace the relay (contactor); replace the micro switch or contact piece; tighten the slider screw and reset the backing plate; replace the limiter transmission gear; replace the button.
3) The hand zipper does not move. The cause of the fault: the ring chain blocks the cross groove; the pawl does not come out of the ratchet;
Solution: Straighten out the ring chain; adjust the relative position of the pawl and the pressure chain frame; replace or smooth the pin.
4) The motor vibrates or makes a lot of noise. Causes of the fault: the brake disc is unbalanced or cracked; the brake disc is not fastened; the bearing loses oil or fails; the gear meshes not smoothly, loses oil or is seriously worn;
Solution: Replace the brake disc or re-adjust the balance; tighten the brake disc nut; replace the bearing; repair the gear at the output end of the motor shaft, smooth or replace it; check the motor, and replace it if it is damaged.
Motor structure of electric rolling gate
1) Main controller: It is the commander of the automatic door. It issues corresponding instructions through a large-scale integrated block with an internal command program to direct the work of the motor or electric lock system; Amplitude and other parameters.
2) Power motor: Provide the active power for opening and closing the door, and control the door leaf to accelerate and decelerate.
3) Induction detector: responsible for collecting external signals, just like our eyes, when a moving object enters its working range, it will send a pulse signal to the main controller.
4) Door spreader running wheel system: used to hang the movable door leaf, and drive the door leaf to run under the power traction at the same time.
5) Door leaf travel track: Just like the rails of a train, the spreader wheel system that binds the door leaf makes it travel in a specific direction.
Maintenance knowledge of electric rolling shutter doors
1. During the use of the electric rolling door, try to keep the controller and voltage stable. It is forbidden to install it in a very humid environment. In addition, do not open the remote control at will. If you find that there are wires winding or knotting on the door, you should deal with it in time. . Pay attention to whether the channel is blocked, which hinders the door body from descending, and if any abnormal response occurs, immediately stop the motor operation.
2. It is necessary to check the switch of the up and down travel of the electric shutter door regularly, and add lubricating oil to the travel controller to maintain normal and good operation. The rolling shutter door is in an appropriate position when it is opened or closed, and the electric rolling shutter door is strictly prevented from being pushed to the top or bottom or reversed during the inspection process. If there is an emergency, stop the rotation immediately and cut off the power supply.
3. It is best for the operator to regularly check the manual switch and manual lifting decoration of the electric rolling shutter door to prevent the electric rolling shutter door from malfunctioning in an emergency or causing unnecessary safety accidents.
4. Keep the track running smoothly, clean the track of the electric rolling door in time, keep the interior clean, add lubricant to the rolling door motor and transmission chain, check the components in the control box and the switch control box, fasten the wiring ports, fasten screws, etc. , Clean the dust and dirt inside the control box, on the surface and on the buttons to prevent the buttons from getting stuck and not rebounding.
Optional installation of electric rolling shutter door
Curtain specification
Generally, small single garage doors (within width 3m and height within 2.5m) use 55 or 77 curtains, and large double garage doors use 77 curtains.
System matching
The rolling garage door reel generally uses a round tube with a diameter of 80mm, and the size of the end seat varies according to the size of the door. It is determined whether a cover is required based on the usage.
Purchase method
First, whether the electric rolling door supports manual function, the manual function should be convenient and fast. When the power is off, turn the clutch 90 degrees, and you can push it to run.
Second, the electric rolling shutter door cannot have the phenomenon of inertial sliding, and must have the function of double-sided automatic locking.
Third, in order to improve the smooth operation of the electric rolling shutter door, it is necessary to increase the pulling force, so our factory adopts the production and installation technology of 8-wheel front and rear drive and continuous row of gears.
Fourth, observe whether the structure of the electric rolling door is precise, the degree of lubrication is good or bad, and the heat dissipation of a good electric rolling door is relatively good. It adopts full gear rotation, no chain, no belt, and thus enhances the overall life of the rolling door movement.
Installation method
First, draw a line at the opening of the door frame to be installed. Indicate the size, and then ask the staff to design a suitable electric rolling door. It is worth noting here that the height of the frame is a little higher than the height of the door leaf.
Second, first fix the door frame of the electric rolling shutter door. Here, the fixing plate at the lower part of the door frame must be removed first. (Note: Grooves should be reserved on the ground on both sides of the opening. After the calibration is qualified, fix the wooden wedge, and the iron feet of the door frame and the embedded iron plate parts should be welded firmly. Use cement mortar or fine stone concrete with a strength of not less than 10MPa to firmly plug it. Can.)
Third, install the main door leaf of the electric rolling shutter door leaf. It is necessary to ensure that the electric rolling shutter door is integrated with the wall, and the sealing performance must be done well, and then the opening and the wall are painted. After the painting is completed, the door gap should be even and smooth, and the electric rolling door should be free and easy to open, and there must be no excessive tightness, looseness or rebound.
