45-95 m³/min High-Efficient bearing-levitation centrifugal blower

Introduction

Maglev blower is a new type of blower, which uses the technology of Maglev bearing to eliminate friction completely and improve the mechanical performance of blower fundamentally. Compared with the traditional fans, maglev blower has the advantages of high efficiency, energy saving, low noise, convenient installation, structure integration, high cooling efficiency, low maintenance, convenient remote control, which can ensure the running stability of the sewage treatment plant and reduce the system replacement cost, so it is favored by many users and preferred by many contractors.

Blower is the common equipment of sewage treatment plant at present and the main energy consumption equipment. Traditional fans have disadvantages of high energy consumption and very loud noise, which not only increases the operating cost of sewage treatment plant, but also causes noise pollution around. While the magnetic suspension single-stage high-speed centrifugal blower has the advantages of high efficiency, less space demand, wide range of flow regulation, high level of automation, and now has been widely used.

Technical Principle

Magnetic suspension bearing, also known as electromagnetic bearing, replaces the traditional mechanical bearing through a kind of technology of magnetic force by levitating the rotor. The rotor of the magnetic bearing is ferromagnetic, which keeps relative balance and levitation under the action of gravity through the attraction of the upper and lower combined iron batteries; when the external force interferes, the rotor deviates from the original suspension center, and the displacement of the rotor relative to the balance center is detected by the sensor, and the electric state signal which is formed after being sampled by the signal A/ D is transmitted to the controller.

The high-speed computation device in the controller generates real-time control signals after pre-set control logic algorithm calculation, that makes the electromagnetic force on the electromagnet to compete with the external force, and makes the rotor return to the suspension center for continuous and stable operation. At the same time, the bearing accurately controls the rotor axis position with more than 10000 times signal acquisition per send and real-time correction, and the axis deviation is controlled within 10 μ m. With the self balancing technology, the vibration is much less than that of the traditional bearing.

Product feature

By using frequency conversion to adjust output parameters and non-contact rotation, it can effectively save energy and reduce operation and maintenance costs.The equipment is small in volume, light in weight and easy to install and operate. Low noise and no vibration during operation.
