192-236 m³/min Oil-free bearing-levitation centrifugal blower - the great substitute for Roots blower

Introduction

As a key equipment of the sewage treatment plant, the blower plays an important role in supplying oxygen to the activated sludge system during production. It is an important equipment to maintain the normal growth and reproduction of the activated sludge, and also the main energy consumption equipment of the sewage treatment plant.

Composition

The magnetic suspension centrifugal blower is mainly composed of high-speed variable frequency motor, magnetic bearing, impeller, frequency converter.The impeller shaft adopts magnetic bearing, no mechanical friction, and the speed can be as high as 33000rpm.

Magnetic bearings are equipped with backup batteries for power-off protection, monitoring sensor for monitoring the alignment state of bearing in real time, and automatically compensating the alignment and balance of rotor.

Operation

On/off and adjustment range:

It is convenient to start and stop the magnetic suspension centrifugal blower. The air volume at the outlet is adjusted by the frequency converter, and the adjustment range of the magnetic suspension blower for SV is 45-100%, which can meet the air volume demand of water quantity and quality change, without frequent machine start and stop.

Output air quality:

The output air of Maglev blower is oil-free air, which is conducive to the growth of microorganisms in activated sludge system.

Operation in hot season:

The cooling and ventilation system of magnetic suspension centrifugal blower is designed reasonably, and it can still run normally at 35-37 ℃ in summer.

Machine installation:

The magnetic suspension blower occupies a small area, does not need the foundation embedded parts, is installed quickly, and the operation noise is not more than 85 dB.

Features and advantages

• Energy saving and high efficiency: because the magnetic bearing is adopted, it has no contact, no friction, no lubrication, and is not easy to cause contact and mechanical loss, and does not need speed adjustment. At the same time, the speed of the blower can be adjusted according to the working conditions, which can save more electric energy for users. The most important thing is that it can realize the change of pressure and flow by adjusting the speed according to the change of external factors. Compared with the traditional blower, it can save 30% energy, and the effect of energy saving and emission reduction is significant.
• Low noise: the magnetic suspension blower adopts the magnetic suspension bearing technology, which has no mechanical friction at all. There is no noise generated by the mechanical friction of the traditional blower. All the noise comes from the air flow, and the noise is no more than 85dB
• Convenient installation: the overall structure of the maglev blower belongs to the box structure, which adopts the self balance technology and active vibration reduction design to minimize the vibration of the body. Therefore, the installation of the equipment does not need to be based on the general horizontal ground. At the same time, the four foundation of the equipment itself can be adjusted horizontally, further relaxing the installation conditions. After landing, the equipment can be started and used after connection management, which is very convenient.
• Integrated Structure: the imported filter, cooling system, full-automatic anti surge system, power failure and fault protection system of the fan have achieved a unified integrated design, and users do not need to purchase other components separately. At the same time, the Chinese touch screen of the fan is displayed in real time. Operators can adjust their own operation procedures according to the observation screen, so as to reduce the occurrence of safety accidents caused by improper operation, which is simple and convenient.
• High cooling efficiency: the cooling system of the fan adopts the combination of air cooling and self circulating water cooling, so as to achieve the best cooling efficiency, avoid the damage caused by motor heating, extend the service life of the motor, and improve the stability of the equipment.
• Remote control: the fan adopts PLC + GPRS control technology. It not only realizes the overall central control of the fan operation, but also realizes the remote control of the whole process of the fan operation. Once the fan fails, it can immediately find out and make corresponding measures for remote maintenance and debugging. At the same time, it also has the functions of storage, memory and remote acquisition control
• Maintenance free: integrated design, skid mounted structure, one key start stop. Daily operation, no mechanical maintenance, no need to replace the lubricant and mechanical parts, just replace the filter
