Elevator ideas and methods of mechanical troubleshooting

2014/1/17 10:28:04

Elevator mainly by the mechanical structure, drag loop , electrical control components, thus the elevator malfunction is mainly mechanical failure and electrical failure. Therefore , when it encounters an error , we must first distinguish between a mechanical failure or electrical failure , and then determine which part belongs to which system failure , the last on which to find fault by which components or parts .
First, the basic reason for the elevator mechanical system failures and major components formed
1 loose connections
Elevator in the process of continuous operation, due to vibration, installation accuracy is not higher cause loose fasteners , mechanical components shifted relative degree of loss or loss of coordination , resulting in wear and tear , collision , resulting in damage to the elevator parts and cause malfunction .
2 Injured operation of natural wear and tear
Mechanical parts when in operation , will inevitably produce wear. Worn to a certain extent , is bound to affect the normal operation of lF . If not promptly replaced, it will lead to malfunction or even personal equipment accident . . Usually insist on an elevator for cleaning, lubrication, adjustment , inspection , we can guarantee the normal operation of the lift.
3 poor lubrication system
Good lubrication can reduce the friction between the parts and reduce wear and tear, but also can play cool , shock absorption, cushioning , rust and other effects , thus extending the life of the elevator . Lubrication system failure or improper lubrication , rotating parts are heat will cause the elevator burned ( axle ) or to scroll ( slide ) component damage , causing the elevator not functioning .
4 . Mechanical fatigue
Some parts of the elevator, for example, the traction rope , etc., are often subjected to bending stress , shearing, stretching , resulting in fatigue , making mechanical plastic deformation ( minus ) is small. When this component force exceeds its ultimate strength , fracture and cause malfunction occurs .
For these reasons, we must adhere to the timing of the elevator , regular maintenance. Once the elevator failure, maintenance personnel must immediately rushed to the scene , use the elevator , managers understand the failure occurred after listening carefully to their views. In this case, if the elevator can also run the application inspection speed elevators running up and down the operation several times by listening to sounds, smelling , touching hands and other means , to observe and analyze the mechanical and location determine the fault occurred.
Elevator mechanical failure manifested as vibration. Sound, heat , leakage, contamination , etc., it manifests itself loose reason , variable -tung , wear, deterioration , etc. . Elevator defective parts caused by the car 's transmission and suspension shake , shaking, trembling , and often emit different ignorant and screams .
Taian Hengtong Elevator is specialized in producing high-quality elevator parts manufacturers, parts manufacturers escalator , escalator parts manufacturers . Product quality and cheap is hot .
