Understanding and Addressing Elevator Vibration Issues

As society advances, elevators play an increasingly vital role in our daily lives. However, encountering vibrations during elevator operation can be unsettling and potentially hazardous. Let’s delve into the causes and solutions to this common issue:

1. Product Quality Influences:
- Defective Bearings: Timely replacement of faulty bearings is crucial to eliminate periodic vibration excitation.
- Vibration-absorbing Rubber: Ensuring uniform support of the host base by replacing deformed rubber can prevent periodic shaking.
- Rope Head Combination Springs: Optimal stiffness matching load capacity is necessary for effective vibration damping.

2. Installation Challenges:
- Guide Rail Installation: Proper verticality, spacing, and alignment of guide rails, along with tightening of expansion screws, are essential to prevent vibration.
- Car Assembly: Correct alignment of the car bottom, center of gravity, and traction sheave rope groove is vital to avoid swinging and vibration.
- Heavy Frame Distortion: Correction of distortions in the counterweight frame and proper installation of counterweight plates and compensation chains are necessary.

3. Debugging Techniques:
- Guide Shoe Clearance: Adjusting clearance and parallelism properly is crucial to prevent jitter.
- Wire Rope Tension: Ensuring even tension of wire ropes prevents wear and synchronizes operation.
- Electrical Adjustment: Proper adjustment of torque, acceleration curve, and feedback reduces vibration during starting, stopping, and operation.

Moreover, external factors like changes in elevator weight due to decoration can also impact its balance coefficient, affecting operational comfort. Regular inspection and maintenance are key to promptly addressing these issues and ensuring safe, comfortable elevator operation.
