Characteristics and Advantages-Technological Progress
Comparison with contact bearings - Maglev bearing enjoys many advantages
Performance
Traditional Contact bearing
Maglev bearing
Speed
<10,000 rpm
RPM Up to hundreds of thousands
Lubrication
The lubrication system is complex and bulky
No lubrication required,
the whole machine structure can be reduced by half.
Energy consumption
Contact abrasion, high energy consumption
< 1/10 of Contact bearing,
the whole machine can save more than 40% energy.
Temperature
The working temperature generally does not exceed 100 C.
It can work in high and low temperature environment
and could operated at 550 C for long time.
Life time
Less than 8 years, need to be disassembled and replaced
It has a life of more than 20 years
no need to be disassembled or maintained.
Stability
Unable to actively control, poor stability
can actively control & adjust the dynamic behavior of the rotor with high stability, real-time monitoring and high reliability.
Characteristics and Advantages-Economy
Taking the aerator for water treatment as an example, the Roots blower with traditional bearings is compared with the magnetic suspension blower with magnetic suspension bearings.
1. Maglev blower can save more than 40% energy than Roots blower.
2. The medium-sized sewage treatment plants with daily capacity of 50,000 tons adopt magnetic suspension blowers, which can save 1.5 million degrees of electricity per year.
3. In 2013, there were 3114 sewage treatment plants with daily treatment capacity of more than 5000 tons in cities and towns, which saved 3.849 billion yuan of electricity per year.
Characteristics and Advantages-Structural Advantages
Characteristics and Advantages-User Experience Advantages
Environmental protection and low noise
1. Running quietly, the noise at 1m of the whole machine is lower than that at 1m.80dB, no need to install additional sound insulation device.
2. Small vibration, almost no sense of equipment when running.Vibration reduces the requirement of equipment foundation.
3. Clean and tidy environment, clean equipment and upgrading work Environmental quality.
Intelligent control
1. LCD touch screen control, operating conditions at a glance, real-time display of process parameters.
2. It can be controlled remotely and adjusted by multi-equipment linkage, so as to achieve the best use efficiency.
3. Various control modes to meet different production control needs.
