Elevator noise is a common noise in residential areas. When the elevator is running, the noise value is too high. It seriously exceeded the national standard and had a bad impact on the daily life of the surrounding residents. The elevator sound insulation treatment scheme can effectively solve the problem of elevator noise. After treatment, it is less than 45 dB during the day and no more than 35 dB at night. Comply with relevant national noise emission standards and achieve the effect satisfactory to residents.

Elevator sound insulation treatment scheme 1. Noise source The mechanical noise caused by the traction machine in the elevator machine room during operation is mostly medium and low frequency noise. As well as rail friction noise and cabinet vibration noise are noise sources. 2. Damping platform Installing a damping platform under the elevator host can not only isolate the transmission structure of low-frequency noise, but also reduce the transmission rate of noise, vibration of elevator host and holding brake noise, so as to solve the problem of low-frequency noise caused by elevator vibration. 3. Elastic support Use elastic supports to change the solid connection and reduce the noise and noise transmission caused by track friction. 4. Inorganic fiber spraying The use of inorganic fiber spraying in the hoistway can not only improve the sound insulation effect of the hoistway, but also reduce the noise generated by the elevator hoistway as a whole.
