Shanghai Dongfeng Pump and Valve Factory is committed to the production and research of fire pipeline seismic support and water pipe support and hanger. It has rich experience in the industry and is worthy of user trust. The noise analysis and treatment of cooling tower pump unit are conventional cooling tower noise sources, mainly wind noise of top exhaust fan and water spray noise of lower layer
Other main sound sources include: fan noise, reducer noise, motor noise, cooling tower piping and valve body noise, cooling pump noise, and noise radiated from casing vibration
The main sound sources are wind noise and water spray noise, which mainly spread outward from the air inlet belt at the bottom and the top of the cooling tower to affect the environment. Therefore, according to its propagation characteristics, the following methods can be taken to control: 1. Install exhaust silencers on the outer edge of the cooling tower top; 2. Install sound barrier in the direction of the cooling tower facing the noise control point; 3. Install a flexible net or anechoic pad on the water receiving tray at the bottom of the cooling tower to reduce the sound of falling water; 4. Install the electric butterfly valve of the cooling tower at the air inlet of the cooling tower; 5. For some projects with high requirements, measures such as damping butterfly valve, electric butterfly valve and cement valve pedestal will also be taken
Shanghai Dongfeng Pump Valve Factory is committed to industrial noise analysis and control, and has produced damping butterfly valve electric butterfly valve, hanging butterfly valve electric butterfly valve, pump electric butterfly valve, etc. Many years of industry experience, welcome to call for consultation
What happened to the leakage of keel electric butterfly valve? If the keel electric butterfly valve leaks oil, it is undoubtedly a very dangerous thing for the electric butterfly valve
