At present, there are many kinds of huge industrial ceiling fans on the market, from the number of fan blades to the fan shape, and the motor brands are complex. As an end user, how to choose high-quality products from these products? To measure the use value of a huge industrial ceiling fan, it mainly depends on its safety and performance. Among them, the performance level is mainly related to the fan's air volume, wind speed, speed, wind pressure, etc. These are the four key points for purchasing large industrial ceiling fans.
The wind speed is the air flow speed at the outlet of the fan, and the unit is generally m/s. The wind speed is one of the important performance indicators of huge industrial ceiling fans. Only the speed value of a certain position cannot fully reflect the performance of the fan. The wind speed may vary greatly in different locations, and the average value is difficult to calculate. The wind speed of the large industrial ceiling fan of Jiangsu Gaxiao Environmental Technology Co., Ltd is comparable to the natural breeze that is the most comfortable for the body. The wind speed mainly depends on the shape, area, height and speed of the fan blade. The influence of the shape design, area and height of the fan blade is more complicated. The faster the fan speed, the faster the wind speed is obvious common sense.
Air volume is the volume of air passing through the section of the fan's air outlet (or air inlet) per unit time. The unit is generally cfm (cubic feet per minute), or cmm (cubic meters per minute). Air volume is the overall measurement index of the performance of large industrial ceiling fans. It is not limited by size, structure, or method, nor is it limited to DC brushless fans. It can be applied to any air diversion equipment. Air volume = average wind speed* wind area. It can be seen that the air volume of the fan basically depends on the wind speed and the size of the wind area.
The speed is the number of revolutions of industrial ceiling fan blades in unit time. The unit is generally rpm, that is, revolution per minute. Rotation speed is one of the fundamental determinants of fan performance indicators. Speed is the easiest parameter to measure for fans. High speed is the source of various "violent" fans and the source of loud noise. The speed basically depends on the performance of the motor used in the industrial ceiling fan. To determine the physical specifications and structure of the fan, all performances are determined by the speed. Rotation speed can affect wind speed, air volume, wind pressure, noise, power, and even service life. The higher the speed, the stronger the performance of the fan, that is, the faster the wind speed, the greater the air volume, and the greater the wind pressure; at the same time, the higher the speed, friction and vibration If there is too much noise, the life of lossy equipment such as bearings will be short; the increase in speed and the increase in power consumption of the motor are also inevitable.
The wind pressure is the pressure difference between the air outlet and the air inlet of a large industrial ceiling fan. The unit is generally mm (cm). Due to the high suspension space of the large industrial ceiling fan, the wind pressure is not an important indicator of the large industrial ceiling fan. Reference indicators for special environmental conditions. Wind pressure is an important indicator to measure the "power" of a fan. If the air volume is compared to the swing power of a weapon, then the wind pressure is the sharpness of the weapon. The wind pressure mainly depends on the shape, area, height and speed of the fan blades. The influence of the first three is more complicated, but the relationship with the speed is simple and direct-the faster the speed, the greater the wind pressure.
