The low -frequency noise of the water pump is not good at sleeping, and the mute water pump is changed to cure "troubles"

The Yangtze River Daily Da Wuhan Client News (Reporter Jin Wenbing Correspondent Yu Haitao) The basement water pumping room was running, and the residents upstairs could not sleep. By replacing the mute water pump, this tricky problem is solved. On the afternoon of June 28, a reporter from the Yangtze River Daily came to the Paris Spring Community in Hongshan Street, Hongshan District to visit the rectification of noise inspection inspection by the pump room.

Mr. Chen in Room 102, Unit 2 of the Community, has found inexplicable noise and vibration from the wall and the ground since he stayed in 2019, especially at night, this vibration is particularly strong. "The shock was panicked, and the elderly and children in the family couldn't stand it and couldn't sleep well.

He and other owners report to the property companies, communities, streets and other units. The matter was quickly found out: In the basement downstairs, there was a pump room with a water pump with 11 sets of frequency frequency water supply pumps to ensure the secondary water supply in the community. Due to the large power of the pump, a large vibration is generated and passed to the wall at runtime, which generates a resonance low -frequency noise, which interferes with some residents on the first floor above the pump room.

"The function of the water pump room is special and cannot be changed. So, how to solve this problem?" Yang Chun, the person in charge of the property managers in the community, said, "After receiving a complaint from residents, we tried multiple vibration reduction measures. For example , Wrap a thick sound insulation cotton for the water pipe water supply pipe of the pump room; install the sound insulation cushion to reduce the vibration of the wall when the water pump is running. "

Considering that the water pump room is a closed space, the property company also tried to open and expand the window in the wall of the pump room. I hope to "dissipate" some noise from the pump room, reduce the low -frequency noise of the pump room to pass through the wall to the residents upstairs to the residents upstairs. Essence However, these measures can only be cured, and the owners are still dissatisfied.

At the end of last year, the Hongshan Street Office and the Paris Spring Project Developer found that the market has a "mute water pump" -the integrated non -negative voltage frequency conversion water supply equipment, which has the characteristics of low noise and low energy consumption. As a result, I contacted 4 sets of water pumps and installed in February this year.

Subsequently, after the testing of a third -party testing agency, the measured noise value was 34-48 decibels in the home and one meter outside the house on the first floor of the pump room to meet the national standards. The environmental inspection case of this "water pump room noise disturb the people" has a good result recognized by multiple parties.

On June 28, Mr. Chen told reporters: "I also know that for this matter, everyone is doing their best, thank you very much!"
