How to Confirm Passenger Lift Rotary Encoder Failure Quickly

Passenger Lift-fujihd.net has not run smoothly when the maintenance costs of the trip a lot of effort to go a lot of detours eventually found to be due to the rotary encoder: 9 Several photoelectric sensor hole closure caused by dust after cleaning the fault eliminated.

An elevator carrying empty car safety gear linkage test after a governor appeared abnormal phenomenon, after the election elevator starter layer about 50mm stopped crawling, I think, since the elevator has a running condition, and no other obvious abnormalities phenomenon, then it is surely a rotary encoder is a problem. The last to find out why it really is a rotary encoder and the computer is connected to the phenomenon of virtual access.
In actual operation, the usual elevator, the elevator malfunction caused by the rotary encoder it is not a minority, it is also quite cumbersome checks, sometimes Although the investigation but still not reassuring.
So I will introduce to you a simple way to confirm rotary encoder failure, can be clearly seen from the drive regulating system diagram, it is was because the rotary encoder makes the computer a drive between an electric motor. Constitute a closed loop speed control system. This solid if there is a problem turn encoder feedback signal is not normal is bound to affect the normal operation of the motor.
If at this point we simply rotary encoder feedback disconnection - become open-loop control, motor if it is capable of running fast now normal state, then you can set the fault does have an elevator on a rotary encoder, or should at Zhu actively look for other aspects of fault. This is to confirm the rotary encoder faults.
Elevator industry maintenance personnel in their work often encounter a variety of phenomena, if careful investigation and analysis, good at summing improve, given the future work will provide a lot of shortcuts.

Elevator Intelligent to Be a Trend In the Future

Elevator made a great contribution in the development of mankind in the city. Original city can only be pie-style, but after the elevator invention, the city development to the high altitude, which greatly enhanced the city's functions, the liberation of the land. Therefore, the development of great significance elevator, it has changed the pattern of human development, changing the concept of urban development, planning, architecture and landscape, it has changed people's lives.

Entrepreneurs must study culture elevator, the elevator to become eco-friendly, humane, safe, no noise of ecological products. Some elevators have armrests, some no handrails, so how do humane, the elderly and children a sense of security it?

Among these, the enterprises should rely more on modern intelligence technology, such as information technology, networking technology. I read a piece of news, several children take the elevator went up 20 multi-building, this building was not completed, after which several children go get down. Police, parents, social masses looking for a couple of days did not find it, but fortunately the master site was later discovered. As in this case, the elevator can not be done intelligently? For example, if someone inside the elevator, more than half an hour, then you can not move automatic alarm. I think, smart technology is so advanced now should be able to do.

With the development of the city, the elevator intelligence has become a trend, with the higher repair modern commercial buildings, elevators and integration of networking technology will be the most major upgrade elevator intelligent direction. As long as people trapped elevator incident occurred, the entire system will immediately start the rescue mechanism graded responses.

Things in the elevator control, elevator fault message will be the first time via phone or network transmission to the elevator maintenance personnel. Such as maintenance staff did not dispose of within half an hour, lift maintenance supervisor, residential property company, territorial quality supervision departments elevator control room, are in turn receive alarm information. If the accident is still not been effectively addressed, the sensor will automatically transmit data up administrations level alarm.
