Industrial fans, also named as industrial blower fans, are classified into one type of industrial blowers. The applications of industrial fans range from cooling the temperature in the working environments to assisting the collecting of oil mist and dust. In other words, industrial fans are used to maintain optimal condition of the manufacturing environments for the smooth operation of machine tools and the health of operators.
How can these fans that seem to have simple design make a difference in the environment of factories? During the process of metal cutting or other manufacturing techniques, chips and temperature control are always important issues. For the least influence occurring from friction, which is produced when the mechanism works, lubricants would be applied to the contact surface of each part. In addition, coolants are also used for lowering the heat generated on the working site.
If not properly dealt with, the leftover substance would cause serious pollution to the plant, which only makes bad effect for the machine tools and operators. Once the oil mist or dust is trapped on the machine tools where lubricant or coolant is applied, it would result in tool defection or shortening the life span of the machines. Besides, if these substances enter the bodies of the operators, it would cause harm to the operators’ respiratory system and skin.
In order to deal with these problems, it is recommended that every manufacturing plant should invest an industrial fan. Not only can the industrial fans help remain appropriate temperature, but they can also ensure the smooth operation of machine tools. Depending on the need of each factory, there are different types of industrial fans they can choose from, and we will discuss in more details in the following sections.
With the variation in the scale of each factory, the way they install the fans would be different accordingly. Some fans are mounted on the ceiling or wall, while others are movable units. In addition to the installing methods of the fans, these devices also differ in the operating principles they adopt for their works. To realize the different operating principles, these fans are designed as two main types, including centrifugal fans and axial fans.
Centrifugal fans utilize the centrifugal force to deliver high velocity air to the target, and this can be realized with the design of the structure. From the exterior, there are an inlet where the air is in and an outlet where the air is blown out. The structure of the interior produces centrifugal force and helps generate the high velocity air around the center of the fan. Therefore, the air delivering movement would be radial in the centrifugal fans.
Being the counterparts of the centrifugal fans, the delivering of air in the axial fans is in axial movement accordingly. Therefore, the axial fans are design with a cylindrical housing that transfers high velocity air axially with the blade and propeller. Comparing the centrifugal fans with the axial fans, one obvious difference is that the former are enclosed structure, while the latter are open structure, which may also lead to the different applications they are suitable for.
Similar to the standard type of fans, the basic ventilating function can also be realized with the industrial fans. They are helpful for ensuring the appropriate quality of atmosphere in the working environments. While due to the space specification, they cannot be substituted with the standard fans.
Most applications of machine tools require the consumption of electricity, which would generate high heat during operation. If the temperature of the machine tools keeps increasing, it may damage the machine parts, and thus result in the shortening of machine life. Industrial fans can be used to cool the components, which turn with high speed during operation, in order to maintain the appropriate temperature on the working site.
This function is usually in conjunction with the oil mist or dust collector, which collects and discards the oil mist or dust produced from the working site. With the assistance of industrial fans, they can smooth the collecting process, and make sure the environment is in the best condition.
In the process of precision machining on metal or wood working industry, not only the temperature but the humidity control should also be taken into serious consideration. That is, before the manufacturing process conducted on the workpieces, the fans are able to keep them dry, in order to eliminating the remaining moisture, which is not supposed to be left on the workpieces. Besides, after the products are made, these fans can also help remove the moisture produced as the coolant is applied from the products.
