系统特点

　　1.直接测量转子内物料重量，计量精度不受料仓内物料属性、气流和物料流动特性的影响，计量准确。

       1. It directly measures material weight inside the rotor, whose metering accuracy is accurate and will not be  influenced by material property, air flow and material flow properties.

　　2.轴承密封预判技术及转子悬挂式结构,保证了使用寿命，5年内基本无易损件。

       2. Its bearing sealing prejudging technology and rotor suspended construction can ensure a long service life; within 5 years, there will be hardly any wearing parts.

　　3.重载可调式悬挂结构，称重灵敏度高，并能实时调节。

       3. It's of heavy duty adjustable suspension structure, with high weighing sensitivity whose real-time regulation is possible. 

　　4.实行了预期控制技术，任何时刻的转子负荷及其所处角位移存储在控制系统中，在物料卸出前，由系统的设定流量值和负荷计算出卸料时的角速度，控制变频调速电机的速率，实现定量喂料，技术先进，喂料稳定。

       4. It adopts the predictive control technology, which saves in the control system the rotor load and its angular displacement at any time. Before the material is discharged, the angular speed during material discharging is calculated on the basis of the system set flow rate and rotor load. In controlling the speed of frequency variable motor, we can realize the quantitative feeding. The technology is advanced, with stable feeding. 

　　5.结构简洁，全密封设计，内部仅有一个低速运行的转子在转动，操作简便，运行可靠，无泄漏。

       5. It's of simple structure and full-sealing design. Inside, there's only a low speed rotor running, with easy      operation, reliable running and no leaking.

　　6.采用轮辐式转子，物料自由下落工作方式，转子旋转过程中物料的波动和填充率的变化较小，喂料均匀，不串料。

       6. It adopts spoke rotor, and the material freely falls during system running. During the rotor rotation, the  material fluctuation and filling rate variation are small; the material feeding is uniform and stable.

　　7.针对特定的工艺及物料特性，采用不同的预给料装置,实现预给料+预期控制技术，双环控制，技术先进，保证了喂料连续稳定，计量精度高。

       7. According to the special process and the material properties, we adopt different pre-feeding device and implement pre-feeding+ predictive control technology (double loop control), ensuring continuous and stable feeding with high metering accuracy.

　　8.独特的长寿命设计，使用寿命长，故障率低，维护简单。

       8. With special design of long service life, the system has a long service life, a low default rate and easy maintenance.
