High Efficient Compressor
High Efficient Compressor: Inverter Centrifugal of Two-stage Compression Semi-hermetic Magnetic Leviation.
Efficient Pneumatic Design
Pneumatic Efficiency of Compressor Improvement:
Equipped with full-fow high-efficiency pneumatic simulation optimization technology to control the flow field.
High-efficiency Closed Impeller:
Equipped with 3-Dimensinal closed impeller to ensure the accuracy of
pneumatic analysis through repeated comparison and correction between CFD analysis and sample unit testing results.
Power Consumption Reduction:
Equipped with 2-stage compression and vapor injection technology, the economizer can achieve adaptive intermediate supplementary cooling. In cooperation with optimized intermediate air intake and pneumatic design to achieve 6% energy reduction compared to single-stage compression.
Anti-Surge Design
Dual compressors operation system design and euippment of switching technology leads to stable refrigerant level and good system condition of Hi-Magi AP Series.
Heat exchange at ultra low approximation temp design leads to lower risk of surge even during unit fouling.
Magnetic Levitation Bearing
Low consumption:
The magnetic levitation bearing is composed of one set of radial and axial magnetic bearings at both ends and position sensors in the middle, with a power consumption as low as 0.3 kW.
No friction:
The rotating shaft operates in suspension, with no direct contact with the bearings, eliminating mechanical friction losses.
Zero Degradation:
Oil-free design during unit operation eliminates the impact of lubricating oil on energy efficiency and ensures the long-term operation performance without degradation.
Precise Bearing Control System
Dynamic Monitoring Frequency > 10000 Times / S:
The Bearing Controller MBC actively controls the rotor position with a frequency of over 10000 Times / S. Micron-level high-precision position sensors monitor the rotor position to ensure precise suspension and rotation.
Shaft Imbalance Monitoring:
Vibration compensation function actively monitors the imbalance of the rotor. High damping characteristics can withstand instantaneous high load changes.
Power Off Protection System
Power Off Protection Process:
Equipped with self-generating motor,high-strength backup bearings and dual emergency power protection system, the motor of Hi-Magi AP Series can achieve auto-switching to generator mode and ensure continuous power supply of magnetic bearings to keep the rotor staying in a normal leviation state.
High-Strength Backup Bearing:
Hi-Magi AP Series units are equipped with one set of high-strength backup bearings at both the front and rear of the motor, which can absorb the impact of the motor shaft during a sudden power outage, protecting the magnetic levitation bearing, sensors, and other components from damage.
