Characteristics of Magnetic Suspension Centrifugal Blower

Author:


The main components of the magnetic Suspension Centrifugal Blower are high-efficiency centrifugal impeller, magnetic bearing, permanent magnet synchronous motor and special frequency converter.The magnetic Suspension Centrifugal Blower is an integrated design. Its high-speed motors, frequency converters, magnetic bearings and micro-processing control panels are all designed and integrated in one. The core technology of the magnetic Suspension Centrifugal Blower is magnetic bearing and permanent magnet motor technology.

(1) High-speed centrifugal impeller.The magnetic Suspension Centrifugal Blower impeller uses three-dimensional flow theory design and parameter optimization to maximize the efficiency of the impeller and a wide working area.Magnetic Suspension Centrifugal Blower is made of high strength wrought aluminum or titanium alloy with strong deformation resistance.Precision machining by CNC machining center, better corrosion protection.

(2) High-speed permanent magnet synchronous motor.Install permanent magnet on motor spindle to ensure spindle magnetism.The winding of the stator silicon steel sheet of the motor generates oscillating magnetic force, which keeps the rotation speed consistent with the oscillating magnetic field and synchronizes during operation.The permanent magnet motor uses magnetic bearing, which has the characteristics of no mechanical friction, low noise, low vibration and long service life. The maximum speed can reach 50000r/min.

(3) Magnetic bearing.The magnetic Suspension Centrifugal Blower is highly efficient, wear-free, maintenance-free, oil-free, and oil-free air because the shaft is suspended stably by means of a controlled electromagnetic suction and the shaft is free of any mechanical resistance during rotation.

(4) Intelligent motor control system.Magnetic Suspension Centrifugal Blower generally uses vector-free frequency conversion control to control the rotation of permanent magnet motor by adjusting the frequency, and then controls the flow of blower to meet various operating conditions.Intelligent control systems can predict surges and achieve local control, and equipment-mounted systems enable remote monitoring and data transmission.
