Noise phenomenon of high temperature fan
Noise is a sound that can easily cause annoyance or harm to human health, so it is difficult for people to accept this sound, however, high-temperature fans in use for a period of time, some users find that the fan will often appear noise phenomenon, in order to our work efficiency, we need to quickly solve the fan noise problem, to effectively ensure the use of the fan.
A. What is the harm of noise
The noise generated by the operation of high-temperature fans is more complex, it is a variety of different frequencies of sound from the irregular chaotic combination, not only affect the organization and management of production, but also seriously damage the physical and mental health of employees so that the work efficiency is low.
Second, the noise treatment how to carry out
1、Installation of anechoic devices Fan in high-speed rotation will produce strong aerodynamic noise, in order to stop the sound spread outward while not obstructing the airflow through the fan airflow channel installation of anechoic devices, so that the fan's aerodynamic noise yi to control.
2、Installation of sound insulation device Sound insulation is a common technical measure in noise control engineering, the use of various panels and components of the wall as a shield or the use of maintenance structures, the noise control within a certain range, so that the noise is blocked in the transmission and can not pass smoothly, so as to achieve the purpose of reducing noise.
3、Use of sound-absorbing materials In the wall or ceiling decorated with sound-absorbing materials, sound-absorbing structures or hanging sound-absorbing panels in the space, the sound-absorbing body mixed sound will be absorbed. In the acoustic noise reduction methods sound-absorbing materials are important, and need to choose reasonable materials according to the field noise source analysis.
The above is the solution on high-temperature fan noise, in strict accordance with the above methods, specific problems specific solutions, to fundamentally eliminate the noise phenomenon, to protect people's physical and mental health at the same time, to enhance the efficiency of the use of fans.
Fan as a common factory equipment, for friends working in the factory will not feel unfamiliar, in fact, the fan because of the frequent and continuous work, so it is easy to have some damage, usually for the fan must do a good job related to maintenance work to
Low noise centrifugal fan selection needs to pay attention to which points? As the fan get the wrong model specifications will jeopardize the normal application. The key performance parameters of the fan are output power, air volume and working pressure.
Before installation, all parts of the fan should be thoroughly checked. Whether the machine is complete, whether the direction of rotation of the impeller and the casing is consistent, whether the connection of each ministry is tight, whether there is damage to the impeller, spindle, bearings and other major parts, whether the transmission group is flexible and so on. If problems are found, they should be repaired and adjusted immediately.
