What to do if the security door of the cell unit is very loud when it is closed

Can drip oil on the hinge.

Regular maintenance will reduce wear and tear to avoid sound, of course, many advanced door axes are installed between the upper and lower hinges, and nylon pads are installed. There is no sound, and it is recommended to refill the oil regularly and lubricate it.

The squeak when the door is opened and closed is generally caused by rust on the hinge, you can smear some lubricating oil on the hinge of the anti-theft door, usually if there is regular maintenance, there will be no problems, in addition, it may be caused by loose adhesive strips, hinges, etc., and the hinge needs to be reinstalled to solve.

The landlord's question is a bit general, does this sound refer to the sound of the door closing or the hinge (hinge) part of the door?! I'll talk about both.

The first case: the closing sound is generally loud, mainly due to the choice of locks and the problem of the door closer.

1.If the door of your cell is electrically locked, the sound will be relatively loud, normal, because iron meets iron, no sound is impossible. If you want to solve it, you can replace it with an electromagnetic lock, which basically avoids the noise of iron hitting iron, but the cost is slightly higher.

2.It is also possible that the closing speed of the door closer has not been adjusted, so that the door closer will close heavily with the unit door, and the sound must be loud. The closing speed can be adjusted by the screws on the door closer arm, so that the door can be closed as slowly as possible, in which case the noise will be reduced.

The second situation: there is a problem with a part of the door body and the part connected to the hinge, or the door leaf sags, or the hinge is not concentricity. If the door is newly installed, then find the installer to debug it, generally the hinge there will be a sound, zirconium oil can be temporarily relieved, but the symptom is not the root cause, the main thing is to install the door frame to the horizontal and vertical position, and then adjust the hinge screws, debug the gap of the door, to ensure that the door body is positive, so that there will be no fan and frame rubbing sound and hinge sound.

I can think of that, I hope it will be useful to the landlord, if it is in Beijing, the door products that have passed the warranty period need to be repaired, you can contact me (hee-hee, not free of charge, a small advertisement, do not report) If the warranty period has not passed, then hurry up to the property to complain.

Pay attention to the anti-rust lubrication of hinges and hinges. Otherwise, there will be rust and abnormal noise. The hinge lacks anti-rust lubrication, which affects the appearance, squeaks and affects the rest.

Macalon and other well-known hinge brands use tiger head hotolube or Kruber hinge grease, colorless and transparent, good adhesion and good durability. There is a 130-gram tube package in the leopard, which is also suitable for sliding door slides, etc. Apply grease directly to the hinge and it will slowly penetrate into the hinge.

The maintenance interval is four to six months.

It is not advisable to use lubricating oil or ordinary butter, which is easy to lose or freeze at low temperature, and will volatilize harmful odors. Vegetable oil quickly rancid, develops odors and loses its lubricating effect.

Keep the security door open...
