    How to effectively extend the service life of negative pressure fans? Generally speaking, the service life of negative pressure fans can reach 10-15 years. How to achieve the expected results? Today, the Shanghai fan manufacturer -Huihong Fan Factory Xiaobian will give you tips on how to truly and effectively extend the life of negative pressure fans.

    Negative pressure fans are common workshop and plant ventilation equipment. There are many types of negative pressure fans on the market. Some of the negative pressure fans have a short service life after installation and use by on-site factories and enterprises. The result is very bleak. However, as our professional fan factory in Shanghai, the Huihong negative pressure fan we produce is generally used for 20 years without any problems, and properly maintained, it can always maintain the advantages of energy saving, high efficiency and large air volume. What if the service life of the negative pressure fan is effectively extended? Need to start with material selection and maintenance. Today, I will explain to you by the editor of the Shanghai fan manufacturer-Huihong Factory.

    Today, the focus is on how to choose this piece of negative pressure fan. We will explain about the maintenance and repair in the subsequent chapters.

    In terms of material selection: First of all, from the perspective of the material of the outer frame, the negative pressure fans on the market are mainly FRP glass fiber (glass fiber reinforced plastic), galvanized sheet, plastic steel and so on.

    The galvanized sheet negative pressure fan is made of galvanized iron sheet (commonly known as tinplate), the most common negative pressure fan in the market. Because of its affordable price, many negative pressure fans choose this material, but its service life is short;

    Plastic steel material, rarely used on the market at present; FRP glass fiber material, that is, fiber reinforced plastic, has the characteristics of light weight, high strength, good corrosion resistance, good insulation performance, low thermal conductivity and so on, so this kind of negative pressure fan High temperature resistance, acid and alkali resistance, light and stable, longer service life.

    Secondly, from the perspective of transmission methods, there are mainly two types: direct and belt. The direct negative pressure fan blade is directly installed on the motor, which reduces the power loss caused by the transmission. The fan of the same power, the direct air volume is about 10% larger than the belt type, and there is no noise caused by belt friction. However, after the belt-type negative pressure fan is used for a long time, the belt will loosen, and the air volume of the fan will obviously decrease after loosening.

    Finally, it depends on the blades. The material of the blades of the negative pressure fan is divided into aluminum alloy, stainless steel, aluminum alloy sanding, aluminum-magnesium alloy die-casting, nylon and iron, etc. Different materials are suitable for different places. Commonly used are aluminum alloy, stainless steel, aluminum alloy foundry blades. The aluminum-magnesium alloy die-casting blades have better high temperature resistance and are relatively stable and difficult to deform and break. Nylon and iron blades are mainly used in acid and alkali places, such as electroplating plants.

    To effectively extend the life of a negative pressure fan, the first thing you need is to choose a good material. As introduced by Xiaobian above, the FRP negative pressure fan can be used for a longer time to a certain extent, and it is indeed a product with excellent materials A foundation for extended service life.

    The material explanations above have been completed. I hope our explanations are exhaustive. In general, Xiaobian recommends FRP negative pressure fans, and the price of FRP negative pressure fans is not very high, about 1000-2500. It may meet the basic usage needs, so when you buy a negative pressure fan, you should know more and choose a good one.
