Upgrading of smoke exhaust fan of a global aluminum giant

Upgrading of smoke exhaust fan of a global aluminum giant

Project Background A global aluminum giant has a full industrial chain covering bauxite mining to aluminum electrolysis and aluminum processing, with an annual aluminum production of up to 3.88 million tons and an annual alumina production of about 5.13 million tons. Recently, the company has been facing a series of challenges such as old smoke exhaust fan equipment, unstable operation and high energy consumption. After a comprehensive evaluation and strict screening, it finally decided to adopt SIMO's fan products to upgrade and improve efficiency. The Solution 1.Scientific Design We use CFD simulation and analysis technology to accurately simulate and analyze key parameters such as airflow distribution, speed and pressure inside the fan, and “customize” a high-efficiency pneumatic model for the customer. The fan is characterized by high operating efficiency, stable performance curve and wide high efficiency zone, which greatly improves the overall performance of the fan. 2.Precision Manufacturing In the manufacturing process, we adopt laser cutting technology to realize accurate computerized layout and material placement, ensuring high precision of the fan's external dimensions and small deformation. In order to further improve the performance of the fan, we carry out aerodynamic optimization of the flow channel, making the airflow in the flow channel more smoothly. At the same time, the noise elimination treatment of the spiral tongue, combined with the design of sound insulation cladding layer, effectively reduce the noise level of the fan. 3.Strong Core Drive For the specific working conditions of this project, we designed and launched a high-strength shaft, whose first-order critical speed is more than 1.4 times the working speed, which effectively reduces the axial loss. In addition, we also adopt a high-efficiency collector with a reasonable profile design, which can realize uniform convergence and diffusion of airflow and reduce gas flow loss. Through the optimized cooperation with the impeller clearance, the overall efficiency of the fan is further improved. After a series of optimized design, to ensure that the fan equipment for high-efficiency operation, tested, the fan operating efficiency of up to 85% or more. With the continuous innovation of our technology, the design and performance of high-efficiency centrifugal fans are still improving, and will also meet more customer needs. “China SIMO, Drumming for the Future”! SIMO Fans will continue to uphold the concept of high-quality products and the spirit of service to create greater value for customers and promote the sustainable development of the aluminum industry and related industries. We look forward to working with our global customers to create a brighter future!

Installation Precautions of High Pressure centrifugal Fan

Installation Precautions of High Pressure centrifugal Fan

Installation Precautions of High Pressure centrifugal Fan Centrifugal fan industry have great potential development. The manufacture of centrifugal fan continuous to improve and innovate in the production technical aspect. In recently years, a big step forward in automation to increase efficiency and competitiveness. However it faces the opportunities but also accompanied by great challenges at the same time. Nowadays, infrastructure, factories, residential industries have higher demands or requirements on fans industry. Before high pressure centrifugal fan working, some installation questions should be paid more attention. Those questions affect the centrifugal fan work. Today, some common questions will be showed, hope to help you in installation centrifugal fan. 1. After high pressure fan is installed, slide the impeller by using hand or lever to ensure whether there are too tight or collision phenomenon; have interfere with the rotation of the materials. The commissioning only can be carried out under normal condition. The exposed parts of high pressure air actuator should be shielded. For example, when high pressure air inlet duct is not connected also need to acquire fence or other mounting device.   2. Preferably gum rubber cushion to bear the weight of high pressure air especially is essential for high-power high-pressure fan. 3. For some requirement for noise, mufflers can be installed to reduce noise. Mufflers should be installed at the inlet pipe or the end of the air duct.   4. When using silencer cotton to reduce the noise, please take note of the distance of high pressure fan and tank; high pressure air ventilation and cooling;using gum rubber cushion to bear the weight of the high-pressure turbine.   5. The high pressure air distribution control box must match the corresponding high-pressure fan.   6. High pressure air must terminal by a qualified electrician wiring.Wiring must be correct and reliable especially the numbering terminal on wiring electrical control box must correspondence with the numbering of high pressure air terminal. Grounding must be reliable and it is not a substitute for ground access to zero.   7. High pressure air inlet and outlet pipe connections, hose connections should be used to isolate vibration.

Will the size of the centrifugal fan affect the work efficiency of the machine?

Will the size of the centrifugal fan affect the work efficiency of the machine?

[SIMO Blower:Industry knowledge] Will the size of the centrifugal fan affect the work efficiency of the machine?  Centrifugal fans can be widely used, especially in daily life or industry. Besides, centrifugal fans have some advantages such as  easy installation, simple operation and easy maintenance. Thus it can  be applied in many fields. There are various types of centrifugal fans, for examples low pressure centrifugal fans, carbon steel, stainless steel centrifugal fan, blower and induced draft fan boiler centrifugal fan.  How to improve work efficiency by using centrifugal fans is always concerned by everyone. Now, SIMO Blower is going to explain in detail how to improve efficiency of centrifugal fan elements.   Centrifugal fans is one of the types of fans, but its power is higher. This is most probably due to the centrifugal impeller fan. Fan impeller is the core component for centrifugal fans function. Many people believe that fan efficiency depends on the impeller high speed. Yes, there is a direct relationship between the efficiency of the fan and its speed.  Impeller can be adjusted itself in order to achieve energy-saving by using same energy supplied at the same time. There are two ways for centrifugal fan impeller to improve work efficiency which are from diameter of impeller and inclination of the impeller. If the diameter of the impeller is relatively large, and of course  this centrifugal fan models is large . Then the power efficiency will enhanced. This proved that the main reason for the high efficiency blowers are larger in size.   Next is the inclination of the impeller. If the degree of inclination is relatively small, then the power will be relatively small. Conversely, if degree of inclination is large, the centrifugal fan power becomes large. However, the inclination angle is within a certain range as the inclination of the impeller could not reach 90º. The maximum only can up to an inner acute angle. Otherwise, this centrifugal fan life will be deducted.So, if want to increase the efficiency of centrifugal fan by using the same electric current , the only aspect is to improve the fan’s impeller.
