There will be some problems with the use of home elevators. When relevant, we need to understand related reasons. Then what are the reasons for the failure of home elevators? Next, China Home Elevator Factory will introduce relevant knowledge to everyone.
1. The elevator did not decelerate and closed, and the door closed quickly and made an impact sound.
Reason: The door deceleration limit cannot be reached when the door is closed. The door closing deceleration limit is broken and cannot be opened. Turn off the deceleration resistor has been burnt or the middle ring and the resistance wire are in poor contact.
2. The elevator does not slow down. There was a crash.
Reason: The door opening deceleration limit cannot be reached when the door is opened. The door opening deceleration limit is broken and cannot be opened. The door open deceleration resistor has been burned or the middle ring is in poor contact with the resistance wire.
3. The elevator is too slow to open or close the door.
Reason: The deceleration limit is turned on or off.
4. The elevator door cannot be opened, it can only be closed.
Reason: It may be that the limit of the door open terminal is disconnected and always open.
5. The door cannot be opened or closed
Reason: It may be that the total resistance of the door switch has been burned out.
