In industrial production, coating fans are one of the commonly used equipment. The selection of coating fans is of great significance for the smooth progress of the production process and the performance of the equipment. So, what are the main parameters for the selection of coating fans?Below we will elaborate on the following aspects.
Air volume
Air volume is one of the most important parameters in the selection of coating fans. Air volume refers to the amount of air that passes through the painted fan per unit of time, usually measured in cubic meter hours or cubic foot minutes. When selecting a coating fan, it is necessary to determine the required air volume according to the actual needs of the coating line. For example, the required air volume needs to be determined based on factors such as the length, width, and height of the paint line, as well as how the paint is sprayed, the number of spray guns, and so on. In practice, calculations are generally made based on empirical formulas or simulations to determine the optimal air volume.
Wind pressure
Air pressure is another important parameter in the selection of coating fans. Wind pressure refers to the ability of a painted fan to do work on air, usually measured in Pascal (PA). When selecting a coating fan, it is necessary to determine the required air pressure based on factors such as the environmental conditions at the coating site, the length of the pipe and the degree of bending. Generally speaking, if the pipe length is long or the degree of bending is large, you need to choose a coating fan with higher air pressure. If the air pressure is insufficient, it may lead to insufficient air flow, which will affect the spraying effect of the paint;If the wind pressure is too high, it may cause excessive noise and increase energy consumption.
Power
Power is another important parameter to consider in the selection of painted fans. Power refers to the ability of a painted fan to do work on air per unit of time, usually measured in kilowatts (kW). When selecting a painted fan, it is necessary to determine the required power according to the actual needs. Generally speaking, if the workpiece to be coated is large or the amount of paint to be sprayed is large, it is necessary to choose a coating fan with higher power.
Rotational speed
Rotational speed is another important parameter to consider in the selection of painted fans. The rotational speed refers to the number of revolutions per minute of the coating fan, usually in rpm minutes (r min). When choosing a painted fan, it is necessary to determine the required speed according to the actual needs. In general, if you need to increase the air flow or increase the spraying efficiency, you can choose a painting fan with a higher rotational speed. However, it should be noted that if the speed is too high, it may cause problems such as excessive noise or bearing wear.
Noise
Noise is an important factor to consider in the selection of painted fans. Noise refers to the sound produced during the operation of the painted fan, usually measured in decibels (dB). When choosing a painted fan, it is necessary to determine the noise level that can be tolerated according to the actual needs. In general, if you need to reduce the impact of noise on the surrounding environment, you can choose a painting fan with low noise.
