On Aug 26th, the cracking furnace fans ordered by users in Kazakhstan were successfully delivered. There are 9 fans in this shipment, of which 6 fans are used for the gas generated by the pyrolysis furnace and conveyed under pressure. Inflammable and explosive gas, so there must be no leakage.

Centrifugal fans will wear due to long-term use during the application process. How to avoid the wear of centrifugal fans? First of all, we need to know that the wear of the centrifugal blower will be in many different positions, so different anti-wear measures need to be taken for them. At first, it’s necessary to do a good job on the blade surface. The common advantages of carburizing, plasma surfacing, spraying cemented carbide, and pasting ceramic sheets are to increase the hardness of the blade surface, which in turn improves the wear resistance of the blade to a certain extent.

Many customers are not clear about the rotation Angle when they choose the centrifugal fan. In order to choose it correctly, today we introduce how to distinguish the rotation Angle of the centrifugal fan. 

Impeller is the heart of centrifugal fan.  Different working conditions have different requirements for impeller forms of centrifugal fans.  According to the blade Angle of impeller outlet, it can be divided into three types: forward type, radial type and backward type.

Centrifugal fans can withstand the high temperature flue gas below 1000 degrees.   High temperature fan is a general name for a class of fans, suitable for conveying high temperature gas with slight corrosion, non-spontaneous combustion and working temperature below 1000℃. The dust content of medium should be less than 150mg/m3. It is widely used in chemical petroleum, metallurgical iron and steel, building materials, cement, environmental protection and other fields.

If you want the environment to achieve good ventilation effect, then centrifugal fan must be the first choice. After years of development, centrifugal fan has been deeply rooted in the hearts of people and is widely used in more and more industries and fields. 

Recently, a batch of centrifugal fans used in the biomass boiler system of a sugar plant in Pakistan have been sent to the port after strict inspections.

The impeller is the core component of the fan, which directly determines the overall performance, safety and reliability of the fan. Our company implements strict quality management throughout the whole process from raw materials entering the factory to finished products leaving the factory. The main process is as follows.

Explosion-proof centrifugal fan is a fan that can be used in flammable and explosive plants, and it does not produce sparks during operation. Mainly used in petrochemical and other industries that have explosion-proof requirements.
