Product technology analysis and advantages of LZ250 centrifugal blower

As a new generation of fluid conveying equipment, LZ250 low-energy air suspension high-speed centrifugal blower takes 100% pure oil-free (Oa-Free) technology as the core breakthrough, replaces the traditional lubrication system with air suspension bearings, completely eliminates the risk of oil pollution, and achieves zero maintenance costs. Its core components include a ternary flow theory impeller made of aerospace aluminum AL7075 precision casting, which is processed by a five-axis CNC machining center with a pneumatic efficiency of up to 85%, with an ultra-high-speed permanent magnet synchronous motor (efficiency > 95%) and an intelligent frequency conversion system, which supports stepless speed regulation in the pressure range of 20kPa-120kPa, and the power transmission efficiency reaches 100%. Compared with the traditional roots blower, the energy consumption is reduced by 30%-50%, and the annual power saving of a single equipment can reach hundreds of thousands of kWh, which is suitable for high-energy consumption scenarios such as coal delivery at the kiln head of cement plants, sewage treatment and aeration.

Taking the Tianshui Sinoma cement project as an example, the energy saving rate of 8 equipment after replacement reached 43.7%, and the annual carbon emission reduction exceeded 1,000 tons. In addition, the equipment adopts an integrated compact design, integrates impeller, motor, inverter and intelligent control system, supports PLC to automatically adjust air volume and pressure, and has safety functions such as anti-surge and overload protection, which greatly reduces the operating threshold.
