About elevator noise-Bolt elevator has something to say

Living in a bustling and noisy city, all kinds of noise will inevitably become an annoyance for people. Even the elevators that solve the problem of high-rise residents' travel will produce a certain amount of noise, which will affect the lives of residents. Are you also troubled by the noise of elevator operation?

Elevator noise conventional standard science

At present, there are mainly three types of standards related to elevator noise: one is the quality standard of the elevator itself, mainly including "Elevator Technical Conditions", "Safety Code for Elevator Manufacturing and Installation", etc.; the second is building standards, mainly including "Residential Design Code, "Civil Building Design Sound Insulation Code"; the third is environmental protection standards, mainly including "Sound Environmental Quality Standards" and so on. These three types of standards also have different regulations for the limit of elevator operation decibels: product standards stipulate that the sound of the main engine room should not be higher than 80 decibels, and the sound of the elevator car should not be higher than 55 decibels; the architectural design standard stipulates that the noise should not be higher than 50 decibels during the day. , No higher than 40 decibels at night; environmental protection standards stipulate that no higher than 40 decibels during the day and 30 decibels at night.

Regulatory standards

On October 1, 2008, the "Social Life Environment Noise Emission Standard" (22337-2008) and "Acoustic Environmental Quality Standard" (GB3096-2008) and other new standards were officially promulgated. Establish clear standards for the emission of indoor solid noise (low frequency noise). The noise of the elevator is indeed a headache. Because according to the original standard, elevator noise generally does not exceed the standard. Regardless of the complaints of the victims, the competent government departments cannot rely on them, so it is more difficult to deal with them. Now there are laws to follow, and victims can lodge complaints with government departments, and they will be resolved satisfactorily. The competent government departments are the special equipment management unit of the Technical Supervision Bureau and the complaint unit of the Environmental Protection Bureau. The special equipment management unit of the Technical Supervision Bureau is responsible for the issuance of the elevator operation license. If it fails to meet the standards, they will order the relevant unit to make rectification, if not, they will revoke the elevator operation license in accordance with laws and regulations;

Applicable standards

Domestic regulations on elevator noise standards have been made. “According to the new elevator noise standards established in 2003, the elevator noise value measured in the elevator machine room should be ≤80 decibels.” At present, most domestic brands of elevator noise can be controlled at 60 Within -75 decibels, it can meet domestic standards. Elevators affected by noise also include the mainstream "frequency-modulated and voltage-regulated elevators" and "machine-roomless elevators" that are currently mainstream in the market and the current "permanent magnet synchronous elevators" with very low noise. By taking appropriate measures to reduce vibration, absorbing and sound insulation, and reduce and block the influence of elevator low-frequency vibration through the declining design, the sound level of elevator noise A in the residential room can be less than 35 decibels.

Elevator noise solution

In terms of controlling elevator noise, Bolt Elevator uses a series of innovative sound insulation and noise reduction technologies to control the operating noise below 50 decibels. For example, in the electrical system, it adopts Japan imported Fuji contactor with better mute effect, which greatly reduces Noise trouble caused by elevator operation!
