عربNowadays, many people have modified some domestic elevators in their homes in order to have different decoration and design effects in small apartment homes. However, after the home elevators have been used for a long time, there will be some situations, and the more common ones are abnormal noises. The reason, then what is the reason for the abnormal noise of the home elevator?
The home elevator did not slow down and turned off, the door quickly closed and there was a knocking sound. Reason: The speed limit cannot be reduced when the door is closed. The shop closing speed limit was eliminated and it could not be opened. Turn off the speed reduction resistor has been burned out or the middle ring is in poor contact with the heating wire.
The home elevator did not slow down. There was a crash. Reason: When the door is open, it is impossible to limit the speed of opening and closing the door. The speed limit of opening and closing the door is removed and cannot be opened. When the door is opened, the speed reducing resistor has been burned out or the middle ring is in poor contact with the heating wire.
After common failures of home elevators occur, they should be carefully disassembled, cleaned, and accurately measured according to the relevant technical standards. The common failures should be clarified based on the inspections, and maintenance or replacement should be carried out based on the wear and damage of the equipment. After maintenance or replacement of home elevator components, they must be carefully adjusted and adjusted before they can be delivered to use.
During the operation period of the home elevator, some tightening screws were loosened or loosened due to vibration, which caused some components, especially fitness sports components, to work abnormally, causing the home elevator to be destroyed. Because of the imbalance of the home elevator balance index, or the severe tremor or leveling precision of the car, the relatively serious load is very poor. The speed of the home elevator cannot be controlled, and even the top or bottom end, resulting in elevator speed limiter-safety The clamps moved and the home elevator stopped.
Elevators are large-scale comprehensive equipment that integrates electromechanics. In order to ensure their safety and reliability, elevators have set up preventive measures from many aspects, such as electrical safety equipment and mechanical safety equipment. The elevator itself has at least three protection measures:
First, there is a buffer under the elevator to avoid injury to people when the elevator falls strongly;
The second is equipped with safety gear, when the elevator wire rope breaks or the elevator falls out of control, it will clamp the elevator guide rails at both ends to make emergency braking;
The third is the speed limiter. When the elevator exceeds the planned extra speed of the elevator, it will be linked with the safety gear, and the safety switch of the speed limiter will be activated.
Each elevator equipment needs to be tested by the inspection department for its safety and performance to ensure the safe operation of the elevator.
