Centrifugal compressor with suspend bearings

Centrifugal compressor with levitation bearing is an oil-free air compressor with high efficiency, energy saving and environmental protection. It adopts levitation bearing technology and high-speed permanent magnet synchronous motor integrated direct drive structure, and adopts two-stage compression + intercooler + three-dimensional flow impeller design. Compared with the traditional air compressor, the product does not need a speed increasing gear box, and can save more than 20% of energy; it does not need lubrication, and the output compressed air is 100% oil-free; it has low noise and low vibration; it is easy to install and maintenance-free. The centrifugal compressor realizes the suspension of the rotating shaft through a suspension bearing, and the permanent magnet synchronous motor generates a current with controllable frequency through a frequency converter, and the current is input into a motor stator to generate a rotating magnetic field to drive the rotating shaft to rotate at a high speed. The air is driven by the impeller rotating at a high speed to enter from the air inlet of the volute, becomes gas with a certain flow rate and pressure through the work done by the impeller and the guidance of the volute, is discharged from the air outlet of the volute, is cooled by the intercooler, enters the secondary impeller to be compressed again, and is discharged, thereby realizing the transformation from low-pressure gas to high-pressure gas. Bearing the manufacturing concept of harmonious coexistence of human and environment, the suspension bearing centrifugal compressor is the necessary equipment to achieve carbon neutralization, carbon peak, implement the new development concept and promote high-quality development. It is a more energy-saving and environmentally friendly high-tech product provided by our company for the market and society.

Gearbox-type high-speed centrifugal compressor

Advanced impeller profile, high efficiency, more energy saving. The impeller is designed by three-dimensional flow theory, and the high speed centrifugal compressor has high adiabatic efficiency. Wide range of flow adjustment, applicable to a variety of working conditions. The flow of the fan can be adjusted by frequency conversion, IGV of the inlet guide vane and OGV of the outlet adjustable diffuser, with a wide range of adjustment and high efficiency under non-rated conditions. The equipped anti-surge device can effectively prevent the compressor from surging. Diversity of transmission media. The compressor can transmit a variety of media, through the replacement of the impeller, volute, seal, etc., to meet the requirements of transmitting a variety of media. The fan is compact in structure and small in size. The compressor adopts an assembled integral structure, the compressor body is assembled on the shell of the gear speed increasing box, the lubricating oil system, the motor and the gear speed increasing box are compactly arranged on a common base, and the base is also used as an oil tank. After strict dynamic balance, the rotor has small vibration, high reliability and low overall noise. The moment of inertia of the rotor is small, the starting and stopping time of the unit is short, and a high-level oil tank and an energy accumulator are not needed. Compared with other types of fans with the same flow and pressure, it has the advantages of low energy consumption, light weight and small floor area. Advanced and reasonable fan structure, less wearing parts, easy installation, operation and maintenance. The bearing vibration, temperature rise, inlet and outlet pressure and temperature, anti-surge control, startup interlock protection, fault alarm, oil pressure and temperature control of the lubrication system, etc. of the complete machine are all controlled by the programmable logic controller, so that the operation of the complete machine can be monitored in real time. Less wearing parts and convenient daily maintenance. A series of monitoring and control, such as bearing vibration, temperature, inlet and outlet pressure, temperature, anti-surge control, startup and shutdown interlock protection, fault alarm, lubrication system oil pressure and oil temperature, are controlled by programmable logic controller, and transmitted to the "Zhangguyun" intelligent cloud platform in real time, so that users and project engineers can monitor the operation status of the equipment in real time.
