Installation method of electric shutter door

The electric shutter door is mainly composed of end plate, reel, shutter door motor, transmission chain, guide rail, shutter and control box. It is widely used because of its beautiful appearance, complete functions, convenient control and manual operation in case of power failure. So what is the installation method of electric shutter doors?

Installation method of electric shutter door

1. Check whether the hole is consistent with the product size. The hole size of the fire shutter door can be calculated as 3M. When selecting molding, the width of the hole should not be greater than 5m, and the quotient of the hole should not be greater than 5m, and the position and quantity of embedded parts should be checked. Confirm the size of the hole of the door and its installation (when the inner, outer and middle entrances of the refined body are concrete, embedded parts should be set at the entrance, and then welded with the guide rail and bearing frame. 3 When the entrance of the wall is brick masonry. The expansion anchor bolt can be connected with the guide rail and the bearing frame through drilling.

2. Determine the horizontal and vertical lines for installation, and install them in turn according to the set size. The notch size should be accurate, consistent from top to bottom, and the corresponding notches should be in the same plane, and then welded with the embedded parts in the hole with connectors.

3. The door rolling machine must be installed according to the instructions.

4. The scroll and frame plate must be firmly installed on the concrete structure or embedded parts.

5. A central pillar should be installed in the middle of the wide door body, and there should be slideways on both sides. The installation of the center pillar must be vertical to the ground and firm, but it should be easy to disassemble and assemble. 6. The door leaf inserted into the slideway shall not be less than 30mm, and the width deviation of the door body in the soil shall be 3mm.

7. The water curtain system of fire shutter door is installed under preventive health care, and the nozzle inclination angle is 15.

8. After the installation, manually adjust the door for self-debugging, observe the up-and-down operation of the door body, and power on the door for debugging after it is normal.

9. Observe that the shutter, transmission system and door body should be opened and closed normally and smoothly at a speed of 3-7m/min.

10. Adjust the direction of the brake housing so that the circulating chain faces downwards; Adjust the chain tension, chain 6-10 mm; Adjust the one-way regulator and limiter.

1 1. When installing the drum, you should first find the size and keep the drum shaft in a horizontal position. Note that the distance between the guide rail and the guide rail should be consistent at both ends. Check after temporary fixation, adjust the roof and correct it, and then weld it with the embedded parts of the support by electric welding.

12. Clean, paint or embed the decorative surface of the guide rail wall, and clean up the site.

Common faults and treatment methods

1. The motor is stationary or the speed is low. The fault is generally caused by open circuit, motor burning, stop button not being reset, limit switch action, heavy load and other reasons.

Treatment method: check the line and connect it; Replace the burnt motor; Replace the button or press it several times repeatedly; Toggle the slider of the limit switch to make it separate from the contact of the microswitch, and adjust the position of the microswitch; Check whether the mechanical part is blocked. If yes, please remove the blockage and clear the obstacles.

2. Control the fault location and causes: the relay (contactor) contact is stuck, the travel microswitch fails or the contact piece is deformed, the fastening screw of the slider is loose, and the backup plate is displaced due to the looseness of the backup plate screw.

So that the slider or nut cannot move with the rotation of the wire, the transmission gear of the limiter is damaged, and the upper and lower keys of the button are stuck. Treatment method: replace the relay (contactor); Replace the microswitch or contact; Tighten the slider screw and reset the backboard; Replace the limiter drive gear; Replace the button.

3. Failure cause of hand-pulled zipper: the chain blocks the cross groove; The pawl cannot be separated from the ratchet wheel; The chain press frame is stuck.

Treatment method: straighten out the endless loop chain; Adjust that relative position of the pawl and the chain press frame; Replace or lubricate the pin shaft.

4. Causes of motor vibration or noise: unbalanced or broken brake disc; Brake disc is not fastened; Bearing oil loss or failure; Gear meshing is not smooth, oil loss or serious wear; Motor current sound or vibration.

Treatment: replace the brake disc or readjust the balance; Tighten the brake disc nut; Replace the bearing; Repair, lubricate or replace the gear at the output end of the motor shaft; Check the motor and replace it if it is damaged.

5. Check the supporting position deviation and screw tightness of the electric rolling shutter door, check the tightness of the belt, check the output of the motor controller to clean up the oil and dust in the main casing, check the wear and tear of all parts of the automatic electric door, check the width, speed and braking of the high-speed door, check whether the voltage parameters are normal, and replace the damaged parts. Car owners should also pay attention to the regular maintenance and maintenance of automatic doors. Due to the influence of installation quality and use environment, problems will inevitably occur in the use of automatic doors.

6. If the hidden troubles and minor faults of the electric rolling gate are not handled in time due to long-term lack of maintenance, the motor will run forward after getting a certain running current, and the power will be transferred to the synchronous belt, and then the synchronous belt will transfer the power to the spreader system to open the door leaf; After the door leaf is opened, the controller will make a judgment. If it is necessary to close the door, the motor will be informed to move in the opposite direction to close the door leaf. It will change from a minor fault to a major fault, which may eventually lead to the paralysis of the automatic electric door. When the induction detector detects someone entering, it sends a pulse signal to the main controller, and the main controller informs the motor to run after judgment, and at the same time monitors the number of revolutions of the motor to inform the motor to apply force at a certain time and enter a slow running.

7. Internal liquidity. You may also need to install electric rolling gates to close one or more indoor doors. Operators should always pay attention to the operation of telescopic doors to avoid accidents. Track should be cleaned frequently to avoid debris accumulation affecting operation.

8. Lubricate the driver at least once a year, and regularly lubricate the chain to check the wear and tear of all parts. Parts with serious wear should be repaired or replaced in time.
