China Elevator Lifts Factory share how to ensure that the acceleration (deceleration) that passengers are subject to is always within a safe range? 1. Under normal operating conditions. For elevators in normal operation, the maximum value of the starting and braking acceleration (deceleration) speed recommended by the national standard shall not exceed 1.50m / s2, and the average value shall not exceed 0.48m / s2 (when the rated speed is 1.0 ～ 2.0m / s) and 0.65m / s (when the rated speed is 2.0 ～ 2.5m / s). It should be noted that this value is not a safety limit, but a comfort limit. Such a small acceleration (deceleration) speed will not only cause any discomfort to passengers, but it will become an "up and down enjoyment" to take the elevator. 2. When the safety clamp stops. When the moving speed of the car exceeds 115% of the rated speed, the elevator speed limiter will act. It first uses a device that meets the requirements of safety contacts to cut off the power of the elevator traction machine to stop it. At the same time, the brake action of the traction machine gradually stops the traction machine and keeps it at rest; if the car is cut off after the power is turned off The speed of the car is not reduced, and the speed limiter will immediately pull the car safety gear (or counterweight safety gear, or other forms of upward overspeed protection device) to stop the car-counterweight system. In the whole process of the car from motion to rest, its average deceleration is less than gn. The above content is organized and shared by the China Passenger Elevator manufacturer, hoping to help those in need.
