“Transformer room is disturbing people. Where is the noise?” On the morning of December 5, Bellking’s team walked into the Mingyue Binhe Huating Community. The corridor was quiet. When the property management staff opened the transformer door, a constant buzz came from the pavement. Through the field investigation, it is determined that the source of noise is the low-frequency noise generated when the transformer is running. The ambient noise in the transformer room has been above 70 decibels. As long as the power supply has noise, it is non-stop day and night. After the coordination and communication of various departments, the matrix anti vibration mounts of Bellking Company was finally selected for noise control. The rectification site was as shown in the figure below. The transformer room facilities were completely reformed and rectified in place.
BK-MT matrix shock absorber _ characteristics
1. The spring surface is treated with ED and baking paint, which has excellent anti-rust ability and has passed ASTMB-117 and 8886 salt spray test.
2, spring heat treatment and stress elimination, good anti-fatigue performance.
3, the spring diameter is greater than 0.8 times of the pressure to the rated disturbance height, the maximum pressure in the spring compression is greater than 50% of the rated disturbance.
4, internal use of seismic stopper device, high safety performance.
5, internal design damping structure effectively avoid resonance phenomenon.
6, the full specifications are made of impact resistant corrosion resistant material shell closed combination.
7, the spring arrangement using Hermite matrix, after loading the spring in the best working state, improve the efficiency of vibration reduction and service life.
8, easy installation, save time.
9. Matrix shock absorber for transformer.
