Magnetic levitation centrifugal fan

LeitzMagnetic levitation centrifugal fanThe key technologies include:

1. Ultra efficient permanent magnet synchronous motor

The motor efficiency reaches over 96%, compared to other motors, it has a small size, low power loss, compact anti heat structure, optimized high-speed rotation design, precise speed control, and provides surging power.

2. Magnetic levitation bearing technology

The magnetic levitation bearing system is the core system of the magnetic levitation blower. The motor rotor is fixed between two radial magnetic bearings and two axial magnetic bearings. The position of the rotor is detected by a position sensor, and the position signal is reflected in real time to the magnetic bearing controller. There is no contact between the shaft and the bearing, no need for lubricating oil, extremely low energy loss, high efficiency, and suitable for various working environments.

3. Three element flow turbine technology

Using the theory of ternary flow, the internal space of the impeller is infinitely divided, and a scientific fluid flow model is established for grid division and flow field calculation, ensuring that the safety angle, number of blades, and cross-sectional shape are reasonable and efficient. To avoid separation of blade flow, reduce flow loss, ensure unobstructed and uniform air flow, and guarantee flow and efficiency.

4. Smart Management System

LeitzMagnetic levitation centrifugal fanIn addition to the main control system, it is also equipped with a global wireless communication intelligent management service system, which uses intelligent hardware and software equipment to monitor parameters such as speed, temperature, pressure, flow rate, and power through wireless communication technology, achieving unmanned operation.

5. Other key technologies

Cooling technology: There are air-cooled or water-cooled models with good cooling effect;

Two stage compression technology: efficient matching of two-stage impellers, with a pressure of up to 150kPa;

Intelligent PLC control system: supports communication methods such as 485/dry contact/Ethernet;

Product advantages

1. Super energy-saving: Relying on energy-saving fan technology, the Ritz air suspension fan can save more than 30% energy compared to traditional fans and more than 5% energy compared to similar fans.

2. Ultra high efficiency: The ultra high efficiency permanent magnet synchronous motor is equipped with a ternary flow turbine, which achieves a comprehensive efficiency of up to 86% (traditional Roots blower efficiency is only 55-60%), and belongs to the national second level energy efficiency equipment product.

3. Environmentally friendly and low-noise: small size, light weight, no mechanical friction, no mechanical vibration, no oil pollution, noise below 85dB, traditional fan noise above 100dB.

4. Precision construction: direct transmission, active suspension, supports frequent start stop, UPS power supply provides power-off protection. Vector free variable frequency control is used to control the rotation of permanent magnet motors by adjusting the frequency, thereby controlling the flow rate of the blower to meet various working conditions. The intelligent control system can predict surge and achieve on-site control, and the equipment installed with GPRS system can achieve remote monitoring and data transmission.

5. Long lifespan: Integrated design, modular management, simple construction, small size, ensuring high efficiency, unmanned operation, maintenance free, under normal working conditions (supporting frequent start stop), the service life exceeds 25 years.

6. Carbon reduction and cost reduction: One 37kW wind turbine can save about 190000 kWh of electricity annually, save about 100000 yuan in electricity bills (recycling machine costs for one year), save about 23 tons of standard coal for power generation, and reduce carbon emissions by about 172 tons.
