The methods of reducing noise during the operation of low-speed elevator compensation chain can be started from multiple aspects such as design, material selection, installation adjustment and maintenance.
A well-designed low-speed elevator compensation chain structure, such as wrapping metal chains with elastic materials such as plastic or rubber, can effectively reduce the friction and collision sound between chains. At the same time, by improving the arrangement of the chains and adding buffer devices, the noise generation can also be reduced.
When selecting materials for low-speed elevator compensation chain, low-noise, wear-resistant and corrosion-resistant materials should be given priority. For example, the all-plastic low-speed elevator compensation chain is an ideal choice for reducing noise because of its round cable-shaped PVC or rubber structure, good elasticity and low noise.
The installation position and angle of the low-speed elevator compensation chain have a great influence on its operating noise. During installation, ensure that the low-speed elevator compensation chain is parallel to the car sill to avoid over-tightening or over-loosening. At the same time, the installation status of the low-speed elevator compensation chain and its surrounding components should be regularly checked and adjusted to ensure that they are in the best working condition.
Installing noise reduction devices in the elevator shaft, such as sound insulation boards and sound insulation cotton, can effectively absorb and isolate the noise generated by the operation of the low-speed elevator compensation chain. In addition, shock pads or springs can be installed at the fixed points of the low-speed elevator compensation chain to reduce the spread of vibration and noise.
Regularly lubricating and cleaning the low-speed elevator compensation chain can reduce friction and noise between chains. When lubricating, suitable materials and methods should be selected to avoid lubricants from polluting the chain and the surrounding environment.
For low-speed elevator compensation chain parts that are severely worn, such as chains and chain links, they should be replaced in time. Avoiding the use of severely worn parts to continue operation can not only reduce noise, but also improve the safety and stability of the elevator.
Comprehensive noise reduction measures can also be considered, such as optimizing the elevator shaft structure, strengthening the shaft sound insulation, and adjusting the elevator running speed. These measures can work together to reduce the noise generated by the operation of the low-speed elevator compensation chain.
