Noise, speaking everyone is familiar with the environment in which we currently general noise from random sources, such gallops off vehicles, aircraft whistle, it's noisy, and a variety of ambient noise sources. With the development of modern industry, environmental pollution has also occurred. Noise pollution is a kind of environmental pollution and has become a major hazard to human beings.
Seeking how to reduce noise pollution has become one of the problems that need to be solved in the development of production in all walks of life. In the field of wind turbines, the German Aizhen fan represented by Hangzhou Benmingwo Machinery Equipment Co., Ltd. perfectly guarantees the noise reduction through two unique pre-air intake grooves. This air tank has also become the patented technology of AERZEN and has become the current The industry's first patent to reduce the noise of the return pulse from the source.
Pre-air intake groove patent technology: When the gas enters from the air inlet, the main rotor rotates counterclockwise, which drives the rotor to rotate, forming a closed sealing ring. The internal pressure of the rotor impeller increases, and the external pressure of the rotor impeller is lower than the internal pressure. Under the condition of the air pressure principle, the high pressure will flow to the low pressure, and therefore, a recirculation pulse is formed, which impacts the rotor impeller to form a popping sound and generates noise. However, when there are two pre-intake slots designed by Aizhen in the cavity, when the rotor compresses the gas to form a high pressure, due to the existence of the pre-intake groove, the rotor impeller communicates inside and outside, and the pressure is in an equilibrium state, which is eliminated from the source. The return pulse eliminates the popping sound and reduces noise.
