[Professional elevator shaft sound attenuation scheme].
In today's high-rise buildings, elevators have become an essential means of transportation. However, there will be a certain amount of noise during the operation of the elevator, especially in the elevator shaft, and the noise problem is particularly prominent. In order to solve this problem, the professional elevator shaft sound attenuation scheme came into being. This article will introduce the relevant knowledge of professional elevator shaft sound reduction solutions to help you understand how to reduce the noise problem during elevator operation.
First, the generation of elevator noise.
The noise of the elevator is mainly in the following aspects:
1.Noise generated by the main engine, control cabinet and other equipment in the elevator machine room;
2.The sound of friction between the elevator car and the guide rail;
3.The sound of friction between the elevator wire rope and the traction pulley;
4.The sound of the impact during the opening and closing of the elevator door, etc.
Second, professional elevator shaft silencing scheme.
In view of the above noise, the professional elevator shaft silencing scheme can start from the following aspects:
1.For the noise generated by the equipment in the equipment room, a shock-absorbing pad can be laid under the equipment to reduce the noise generated by vibration. At the same time, the computer room is soundproofed, such as installing soundproof doors and windows, wall soundproofing and other measures to effectively reduce the transmission of noise.
2.In view of the friction sound between the car and the guide rail, guide rail materials with a small friction coefficient, such as stainless steel guide rail, powder metallurgy guide rail, etc., can be used to reduce the noise caused by friction. At the same time, the guide rails are lubricated and maintained regularly to reduce friction sound.
3.In view of the friction sound between the wire rope and the traction pulley, the traction pulley material with high wear resistance, such as ceramic traction pulley, polymer material traction pulley, etc., can be used to prolong the service life of the traction pulley, reduce the number of replacements, and reduce the noise caused by the replacement of the traction pulley. At the same time, regularly check the wear and tear of the wire rope and replace the damaged wire rope in time to reduce the noise caused by the wire rope problem.
4.In view of the impact sound in the process of opening and closing the elevator door, shock absorbers and other buffer devices can be added in the process of opening and closing the elevator door to reduce the impact sound between the door panel and the door frame. At the same time, the installation of the elevator door is accurately controlled to ensure that the gap between the door panel and the door frame is uniform, so as to reduce the noise caused by the uneven gap.
3. Precautions for construction.
When implementing the professional elevator shaft silencing scheme, the following points need to be noted:
1.When carrying out sound insulation treatment, it is necessary to ensure that the flame retardant performance of the sound insulation material meets the requirements of relevant national standards to ensure public safety.
2.When replacing the traction wheel and wire rope, it is necessary to ensure that the performance and quality of the new material meet the design requirements to ensure the stability and safety of the elevator operation.
3.When laying the shock-absorbing pad under the equipment in the computer room, it is necessary to ensure that the shock-absorbing pad is firmly fixed to avoid potential safety hazards caused by loosening.
4.When installing new elevator door panels, it is necessary to ensure that the gap between the door panel and the door frame is uniform to avoid potential safety hazards caused by uneven clearance.
5.When carrying out elevator maintenance, it is necessary to regularly check the operation status and wear of various equipment, and find and deal with potential safety hazards in time.
Fourth, summary. 
The professional elevator shaft sound reduction scheme can effectively reduce the noise problem during the operation of the elevator and improve the comfort of the living and office environment. When implementing the sound reduction scheme, it is necessary to pay attention to the details of all aspects to ensure the quality and safety of the implementation of the scheme. At the same time, for different noises**, different treatment measures should be taken to achieve the best sound reduction effect. I hope this article can help you understand the relevant knowledge of professional elevator shaft sound attenuation scheme, and bring convenience and comfort to everyone's life and work.
