Selection points and methods of installation and maintenance
As a required device in the kitchen, many people often do not know how to choose when they choose it. Next, ventilation will help you to understand the selection points and daily life of smoke exhaust fan through this article.Maintenance method used.
In the process of buying a smoke exhaust fan, you can choose according to the following parameters, which are total power, speed, noise, motor, power, efficiency, full pressure, air volume, work temperature, etc. Generally, generalIn terms of smoke exhaust fan, it can be used normally in environments where the medium temperature is not higher than 80 ° C.
General smoke exhaust fan cannot be operated for a long time under higher temperature conditions, otherwise it will damage its internal components. Therefore, according to the specific environment, you can choose to require different smoke exhaust fan on different temperature.
As a tobacco exhaust fan that can be listed, it should be able to ensure that the medium can work continuously for more than half an hour when the conveying medium is about 280 degrees Celsius, and when the temperature of the medium can cool to the environment, it can still be normal.Run, so that when used in the kitchen, it can ensure that it can work normally and make the airflow in the environment more suitable.
Under the rated speed of the smoke exhaust fan, its pressure curve should be met with the giving curve given in the corresponding instructions in the regional smoke exhaust fan working in the kitchen.The deviation of the pressure generated is about 5%. Whether it is a shaft -flowing fans or a centrifugal fan, this regulation must be followed.
Generally speaking, in the case of the working conditions given in the manual, the limited value of its noise cannot exceed the relevant regulations.Among them, a centrifugal ventilator made from ordinary steel or a professional smoke discharge axis can be used with ordinary steel.
After installing a smoke exhaust fan, because it is under a harsh environment for a long time, it is necessary to regularly clean and maintain it.Because if it is covered with oil for a long time, it will cause the angle deformation to achieve the smoke exhaust effect we want, and even make the impeller lose balance to increase the vibration, thereby damaging the fan.
