- How to judge whether a centrifugal fan is good or bad
- 1.Whether the centrifugal fan performance meets the standard static pressure exhaust volume and meets the standard performance can achieve the air supply volume required by the specific system;
- 2.How high is the efficiency of the centrifugal fan? High efficiency of the fan saves electricity. High efficiency of the fan saves electricity;
- 3.How high is the vibration value at the position of the rolling bearing? Fan bearings with high vibration values are easily damaged, while bearings with low vibration values have a long service life;
- 4.What is the operating noise? Noise is air pollution, harms working mood, and also consumes energy;
- 5.Have you considered the convenience of maintenance? Centrifugal fans are equipment that require regular maintenance, and the oil supply holes, exhaust holes, inspection ports, and rolling bearings should be easily disassembled;
- 6.Generally speaking, you can know the advantages and disadvantages of a centrifugal fan by looking at its appearance. If you keep improving the position, centrifugal fans are generally very good.
Which type of centrifugal fan is the most efficient?
- Impeller centrifugal fans have stronger wind power. Impeller centrifugal fans are divided into two types: forward curved blade type and rear curved blade type.
- The front curved blade centrifugal fan is suitable for transporting high-speed airflow (i.e. small wind resistance), which can improve operating efficiency; the rear curved blade centrifugal fan is suitable for transporting high pressure, high temperature, high humidity, high viscosity, high dust gas and corrosion sexual gas because its structure is stronger.

What are the three types of centrifugal fans?
- Centrifugal fans are divided into three types: static pressure centrifugal fans, dynamic pressure centrifugal fans and diagonal flow centrifugal fans.
- 1.Static pressure centrifugal fan
- Static pressure centrifugal fans are suitable for occasions requiring larger air volume and lower wind pressure, such as ventilation and air conditioning and refrigeration. Their transmission pressure (static pressure) generally does not exceed 2000Pa. Static pressure centrifugal fans can be divided into forward curved plate centrifugal fans, back curved plate centrifugal fans, right angle centrifugal fans and medium pressure centrifugal fans.The front curved plate centrifugal fan has a set of aluminum curved plates in front of the impeller, which allows the gas entering the impeller to flow to the blades, improving energy utilization and achieving higher static pressure and efficiency. The rear curved plate centrifugal fan has a set of aluminum curved plates behind the impeller to better utilize gas energy and improve efficiency. The right-angle centrifugal fan has a wind direction curve of 90 degrees and has high static pressure. It is suitable for air conditioning supply and exhaust systems. Medium-pressure centrifugal fans are suitable for larger gas flows and pressures, and can meet higher system efficiency.
- 2.Dynamic pressure centrifugal fan
- The transmission pressure (static pressure) of dynamic pressure centrifugal fans is usually above 2000Pa, and is suitable for occasions that require higher wind pressure or require long-distance gas transportation, such as industrial production lines, processes, smelting, etc. Dynamic pressure centrifugal fans can be divided into two types: single suction type and double suction type. The single-suction dynamic pressure centrifugal fan has a shorter suction section and is suitable for transporting gases with less dust, such as fresh air supply and return systems. The double-suction dynamic pressure centrifugal fan has a longer suction section and is suitable for conveying dust-containing gas or where both ends need to be connected to pipes.
- 3.Oblique flow centrifugal fan
- The oblique flow centrifugal fan is a new type of centrifugal fan, suitable for large-scale air supply or exhaust situations. Its air volume can reach 600000m³/h and its static pressure can reach 750Pa. The advantages of this type of fan are high efficiency, low noise, large air volume, small and lightweight, and are generally widely used in industrial environments such as metallurgical industry, buildings, and petrochemical industries.
