Elevator safety equipment- speed governor
The elevator speed governor is one of the safety control components in the elevator safety protection system.
When the elevator is running for any reason, if the car is over speed-ed, and even the danger of falling, and all other safety protection devices are not working, the speed limiter and the safety gear are linked to cause the elevator car to stop. live. It is the safety protection device of the elevator. It monitors and controls the speed of the car at any time. When there is an over-speed condition, that is, 115% of the rated speed of the elevator, it can send a signal in time, and then generate a mechanical action to cut off the power supply circuit and brake the traction machine. If the elevator still cannot brake, the safety gear installed at the bottom of the car will force the car to stop. The speed limiter is the command sender and the safety gear is the performer. The combination of the two has emerged as a safe elevator.
The speed limiter safety clamp system is an indispensable safety device for the elevator. When the elevator is over-speed, the operation is out of control, or the suspension device is broken, the speed limiter safety clamp device quickly stops the elevator car on the guide rail and remains stationary. Avoid casualties and equipment damage.
