Common faults and maintenance precautions for automatic doors

Automatic doorAs a new type of product, it is very convenient to use and is widely used in life and work. But when there is a problem or damage to the automatic door, it also brings considerable trouble to the owners. Therefore, it is also very important to understand the maintenance methods of automatic doors. Now we summarize the common faults and maintenance methods of automatic doors

Common faults of automatic doors mainly include the following aspects:

1. The automatic door speed is too slow when the door leaf is opened and closed: This may be due to the controller speed adjustment being too slow, abnormal voltage, the belt may be too loose, the stop wheel may rub against the track, or the movable door leaf may be in contact with the floor It is caused by friction or friction with the guide rail or fixed door leaf. The maintenance method is to lubricate all operating parts of the automatic door, adjust the belt tightness or controller, and finally check and adjust the voltage.

2. The automatic door keeps opening and closing: This may be due to a moving object in the sensing range, the door switch hitting an obstacle, or the radar sensor failing. caused by other reasons. The maintenance method is to first check whether there are obstacles or moving objects within the automatic door sensing range, and clean them in time, Pay special attention Yes, some automatic doors are equippedAnti-pinch function Its working principle is composed of a pair of infrared beams. If blocked, the door cannot be opened. If not, check to see if the test sensor is working properly. If not, replace it.

3. The door leaf shakes when the automatic door is running:

span>This may be due to obstacles or wear on the underground guide rails or swing stops, moving hoists and railsCaused by wear or obstruction. Maintenance is to remove obstructions and replace worn parts.

4. The automatic door leaf cannot be opened:This may be caused by sensor failure, belt detachment, wire connector loosening (short circuit), controller burnt out, motor overheating or foreign matter stuck. The maintenance method is to check whether there are foreign objects in sequence, and check the voltage, sensor, controller, belt, wire connector and other components

Automatic Door maintenance precautions When performing automatic door maintenance, matters need to be paid attention to:

1. Safety first: When performing automatic door maintenance, you must pay attention to safety. First, cut off the power supply to avoid electric shock accidents. Secondly, wear protective gloves and goggles to avoid injuries to hands and eyes. If you climb high, you must be supervised by specialized personnel.

2. Inspection before maintenance: Before repairing the automatic door, it is necessary to conduct a comprehensive inspection of the automatic door to find out the cause and location of the fault. At the same time, check all parts of the automatic door to ensure that there is no looseness or damage.

3. Maintenance operations: When performing automatic door When servicing, follow the steps in the operation manual to avoid improper operations that may lead to larger failures. At the same time, professional tools and equipment should be used to ensure the quality and effectiveness of repairs.

4. Fault finding: Compare the circuit schematic diagram and wiring diagram, after analyzing the working principle of the electric door and forming a suspicious fault point in the maintenance idea, find its corresponding location, use instruments and meters to test, and compare the measured data Compare with normal data, then analyze and gradually narrow down the fault scope, and finally find out the fault point.

5. Troubleshooting: Found After the fault point, reasonable maintenance measures should be taken based on the characteristics of the failed component or other abnormal conditions. For example, for desoldering or weak soldering, it can be re-soldered; for component failure, qualified components of the same model and specifications should be replaced; for short-circuit faults, the cause of the short-circuit should be found and eliminated accordingly.

6. Restore debugging:Replace element After the device is installed, the electric door is often more or less fully or partially debugged.

Automatic door repair Recommendations For automatic door repairs, here are some suggestions:

1. Regular maintenance: Regularly maintain and maintain the automatic door, including cleaning the oil and dust inside the track, checking the wear and tear of various parts of the automatic door, and checking The tightness of the belt, etc.

2. Professional maintenance: If you do it yourself If you don’t know much about automatic door maintenance, it is recommended that you find a professional to perform repairs.

3. Choose a high-quality brand:Choose A good quality automatic door brand can reduce the occurrence of failures.

4. Sign an after-sales service contract:A good full-service automatic door installation and after-sales service contract should be reached between the automatic manufacturer and the automatic door installer or automatic door owner before installation to avoid the automatic door from being in disrepair for a long time.
