Solar water heating system units installed in the top of the roof, when the crew working vibration noise generated by the downstairs of the household living environment.
The vibration noise of solar energy unit is mainly composed of unit, water pump and piping. Due to the mechanical vibration generated by mechanical moving parts such as motor and wind wheel, and the vibration of driving motor, under the radiation impact load, Is excited to produce vibration, known as the structure of the excitation effect. Also referred to as excitation structural noise or solid noise, along the building structure down transmission. Therefore, the vibration of the solar unit noise control program should first consider the mechanical low-frequency damping integrated measures.
Because the vibration of the solar energy unit is low-frequency transmission, the conventional installation method is only with the rubber pad or a single spring shock absorber, it is difficult to meet the indoor noise standard requirements. This is because the elastic modulus of the rubber pad is too small, and the stiffness of the spring shock absorber is too low for low-frequency vibration isolation effect is poor.
Vibration isolation system for the design of solar energy units should follow two technical points, one must use low-frequency isolation vibration isolation system, the unit should use the following natural frequency vibration isolators to achieve higher isolation efficiency; Increase the number of vibration isolation units so that each vibration isolation unit by the minimum interference; Third, the vibration isolation unit should have the appropriate damping to control the device's own amplitude.
In the treatment of vibration and noise, our experience is the second vibration isolation method, because after a vibration isolation, the resonant region after the transmission rate decay rate of 12dB / octave, after the second isolation, the resonant region Transmission rate curve decay rate of 24dB / octave. So the second vibration isolation can achieve higher vibration isolation efficiency. In order to get as much noise reduction effect, we use two-stage non-standard damping system, which can achieve very low natural frequency.
At the same time, because the solar water heating system units are installed in the outdoor, and ultraviolet and rain for some of the shock absorption material will have decomposition and corrosion, so for the shock absorption platform needs special UV and rain structure design.
