Elevator Speed Limiter
Elevator speed limiter
Elevator speed limiter is an important safety device in elevator
system, which is used to monitor the speed of elevator operation
and trigger emergency braking when overspeed, so as to protect the
safety of passengers and equipment.
Elevator speed limiter is generally composed of the following main
parts:
Speed Limiter mechanism (Governor mechanism): speed limiter
mechanism is the core component to control the operation of speed
limiter. It is usually composed of the main body of speed limiter,
detection wheel, Cable (wire rope) and its connecting device, etc.
The speed limiter mechanism is connected with the elevator car
through the cable, and corresponding control is carried out
according to the speed change of the elevator.
Speed limiting rope (Governor rope): The speed limiting rope is the
wire rope connecting the speed limiting mechanism and the elevator
car. It transmits relevant information to the speed limiter
mechanism by monitoring the rope speed during the movement of the
elevator, so as to judge whether the elevator is running normally.
Speed sensor (Speed sensor): the Speed sensor is used to detect the
running Speed of the elevator in real time. It usually adopts
magnetic or photoelectric sensing technology, which can accurately
measure the speed of the elevator and transmit data to the speed
limiter mechanism.
When the running speed of the elevator exceeds the set safe speed
limit, the speed limiter mechanism will automatically trigger the
emergency braking device to stop or slow down the elevator. In this
way, accidents caused by elevator overspeed can be avoided and the
safety of passengers and equipment can be ensured.
