Introduction of Jiangsu Weigu Fluid: How to judge the quality of a magnetic suspension blower?

To judge the quality of magnetic levitation blower, we can start from the following aspects:

In terms of performance parameters

Air volume and air pressure: the air volume shall meet the requirements of gas delivery in production process, and the air pressure shall be able to overcome the resistance of pipeline system and ensure the smooth gas delivery. For example, in the aeration process of sewage treatment, it is necessary to accurately calculate the required air volume and air pressure according to the size, water depth and oxygen demand of the aeration tank. If the air volume and air pressure of the fan are insufficient, it will lead to insufficient aeration and affect the sewage treatment effect.

Energy-saving: High-efficiency and energy-saving magnetic levitation blower can effectively reduce energy consumption costs. You can check its energy efficiency curve, understand the efficiency performance under different working conditions, and choose the model with high efficiency in actual operating conditions. Generally speaking, magnetic levitation blower saves about 30% energy compared with traditional blower, and the products with remarkable energy saving effect have better quality.

Speed stability: A stable speed can ensure the stability of gas supply and pressure, thus ensuring the stability of the production process. Through the measurement of professional speed measuring instrument, the quality of magnetic suspension blower with small speed fluctuation is better under different loads and running time.

Mechanical structure and material aspects

Magnetic bearing: Magnetic bearing is the core component, and its quality affects the performance and life of the fan. High-quality magnetic bearing should have high precision, high bearing capacity, good stability and reliability, which can realize stable suspension and high-speed rotation of the rotor without contact friction and reduce energy loss and mechanical wear.

Impeller: The material and manufacturing process of impeller determine its strength, corrosion resistance and aerodynamic performance. The impeller made of high-strength forged aluminum or titanium alloy has strong deformation resistance, and is precisely machined by a five-axis CNC machining center, which can ensure good dynamic balance and aerodynamic efficiency and make the fan run more smoothly and efficiently.

Motor: Magnetic suspension blower with high-speed and high-power permanent magnet synchronous motor has the characteristics of small volume, light weight, high power density and high rotation speed, and its conversion efficiency is high, which can provide strong power for the fan and run stably and reliably.

Control system aspect

Frequency conversion speed regulation system: The advanced frequency conversion speed regulation system can accurately adjust the speed of the fan according to the actual demand, realize the flexible adjustment of air volume and wind pressure, and further improve the energy-saving effect and operation stability. The measured frequency (output work/input work) of the inverter should be high, such as more than 98%, indicating that its speed regulation performance and energy conversion efficiency are good.

Intelligent control function: The magnetic levitation blower with perfect intelligent control function can realize real-time monitoring, fault diagnosis, alarm protection, etc. of operating parameters, and can also communicate with the upper computer or other control systems to realize remote monitoring and automatic management, which is convenient for operation and maintenance and improves the intelligent level of production.

In terms of operational performance

Noise level: The magnetic suspension blower should run smoothly and quietly, and the noise is usually about 80-85 decibels. Excessive noise may be caused by parts wear, imbalance, airflow disorder and other reasons, which will affect the working environment and people's health, and also reflect the problems of the overall quality and assembly accuracy of the fan.

Vibration: Because of the magnetic bearing technology, the high-quality magnetic suspension blower has no contact between the rotating parts and the mechanical system, no mechanical friction, stable operation and minimal vibration. Through vibration sensor or instrument detection, the vibration value is within the allowable range, and the smaller the better. Excessive vibration will accelerate the wear of parts, reduce the service life of equipment, and even affect production safety.

Reliability and stability

Brand and word of mouth: Choose magnetic levitation blowers with well-known brands and good market reputation. Usually, these products have been tested by the market for a long time, and their quality and performance are more guaranteed. You can refer to other users' evaluation, cases and industry recognition to evaluate brand reliability.

Quality certification: The products have passed the authoritative certifications such as ISO9001 international quality management system certification and EU CE certification, indicating that they meet international standards and requirements in production management, quality control and safety performance, and the quality is relatively more reliable.

After-sales service: Good after-sales service is an important factor to ensure the long-term stable operation of equipment. A high-quality supplier should have a professional after-sales team, which can respond to customers' needs in time and provide technical support, maintenance and spare parts supply, so as to ensure that the equipment can quickly resume normal operation in case of failure.

Appearance and technology

Appearance quality: The overall appearance should be free from obvious defects, deformation, corrosion and other problems, with good surface treatment, uniform and smooth paint, firm connection of all parts, no looseness, leakage and other phenomena, reflecting the manufacturer's production technology and quality control level.

Assembly technology: High-quality magnetic levitation blower has high assembly precision, reasonable fit clearance between components, neat and standardized line connection and good sealing of pipeline interface, which can reflect the quality and reliability of products from details.
