دلایل خرابی آسانسور چیست؟
Various reasons can cause the elevator to break down. To prevent some of these breakdowns, it is enough to pay attention to the elevator standard and take periodic elevator services seriously. Some of the most important reasons for elevator failure are:
Carrying cargo with a non-carrying elevator
Using the elevator more than its nominal capacity
Unauthorized high speed setting for the elevator
The lamp and the elevator fan are too bright
Frequent power outages
Pushing the elevator chassis button too much
Excessive wetting of the elevator cabin
Hitting the elevator door and chassis
Jumping in the elevator car or creating any momentum in the car
Not performing periodic services
According to the above, the reasons for the failure of the elevator can be summarized in three cases: power failure, technical failure, and improper use of the elevator. In the case of improper use of the elevator, it is possible to prevent the damage of the elevator by taking measures such as respecting the capacity of the elevator, not carrying furniture and carrying heavy loads, and also not jumping in the cabin, etc. In the case of technical defects, it can also be avoided with regular periodic services.
چرا آسانسور خراب میشود؟
The things that cause the elevator to fail are as follows:
بالا رفتن دما
In the normal state when the cooling system or elevator ventilation is working properly, its temperature is between 5 and 40 degrees Celsius. But if the cooling system fails, the temperature of the elevator may reach 100 degrees Celsius. This increase in temperature can cause malfunction of the elevator.
روغن آلوده
If the elevator oil is contaminated, the operation of the elevator will be disrupted. For example, if there is bronze in the gear oil, this bronze will wear the crown of the gear.
گرد و غبار
If air from outside the building is used to air condition and cool the elevator, a lot of dust may enter the elevator. The entry of dust interferes with the contacts of the elevator control system. Also, dust sitting on the equipment causes their temperature to rise.
رطوبت
In addition to dust, outside air can also cause moisture to enter the elevator. Moisture can cause some equipment to corrode and rust, resulting in the failure of the elevator. To solve this problem, it is enough to install the cooling system in a way that prevents moisture or dust from entering the elevator.
ساییدگی چرخ فلکه
If the tension of the tow wire is not adjusted, the carousel may wear out. Periodic services can prevent this problem from occurring.
عملکرد بد یاتاقان
If there is vibration in the motor, it may interfere with the performance of the bearing. If a frequency drive is placed on top of this current, the failure of the elevator will be prevented, and while the noise of the elevator will be reduced, its safety will also be guaranteed.
مصرف بالای انرژی
Old elevators generally consume a lot of energy. This problem can be solved by upgrading the elevator system. Because new elevator systems consume up to 75% less energy. Also, new elevators are faster and safer.
آسانسور خراب به چه مشکلاتی برمیخورد؟
A broken elevator can cause many problems. Some of these problems are:
Frequent power outages: In high-traffic buildings where the elevator is used a lot, if the elevator is heavily used, the electricity may fluctuate and change the voltage and the elevator motor may not work well.
Fire and electrocution: wear and tear of the elevator's power supply system, wrong closing of the power supply system and electrical connections can cause electric shock or electrical connection and fire in the elevator.
Sudden stop: Electrical and electronic problems and defects can cause the elevator to stop suddenly. This problem can be prevented to a great extent by performing continuous services.
Long waiting time: broken elevator relays or old elevators cause this problem. You can easily reduce the waiting time by half by replacing the mechanical relay control system with a microprocessor control system.
Floor door not opening: The reason for this could be that the handle of the floor lock is too far from the door opener bow and the bow cannot push the lock back.
Circuit failure when starting the engine: Engine burning or short circuit in the capacitor can lead to the circuit failure when starting the engine. To fix the failure of the elevator in such a situation, the motor or capacitor can be changed.
Failure to turn on the circuit and no current passing through the circuit: the cause of this failure of the elevator can be the disconnection of a part of the electronic circuit. For troubleshooting, all electronic circuits such as connection wires, connections, switches, two plugs and sockets must be checked first with an ammeter, and after identifying the part that has a problem, it must be repaired.
Increasing the temperature of the engine: if the engine is half-burned, the electric current it receives will increase. In the main and auxiliary windings, it is possible to connect the ring or connect the coil to the coil. As a result, the electric current path is shortened and the engine temperature rises.
Loud motor noise when starting without the lift moving: If the centrifugal switch is broken or the main or auxiliary windings are broken, the lift motor will make a loud noise when starting without moving. To fix this problem of the elevator, the centrifugal switch can be replaced or the winding can be fixed.
Stuck in the elevator: Stuck in the elevator can have many reasons; including the visual failure of the elevator, the elevator cabin coming out of the guide rail, the elevator gearbox jamming, the gathering of steel wire on the elevator cabin, etc.
