永磁同步直驱电机在挤出吹塑机中的应用

Application of Permanent Magnet Synchronous Direct Drive Motor in the Extrusion Blowing Machine

针对饮料瓶高密度聚乙烯(High Density Polyethylene,HDPE)挤出吹塑机挤出电机存在的效率较低、维护频繁等问题,某大型食品饮料公司机电研发部门研制出一款低速大扭矩的永磁同步直驱电机,可以去除原有的皮带与减速箱,采用永磁同步电机直接带动挤出螺杆的方式运行。实际应用表明,永磁同步电机采用水冷方式冷却,可以在高温情况下稳定运行,满足生产需求,同时具有无须保养、无须润滑油等优点。该项目节能效果明显,节能率达到17.1%,具有较高的经济价值,能显著减少设备振动和油污污染,降低饮料生产车间的噪声,改善车间的卫生环境和工人的工作环境,减少减速箱等零部件故障的发生。

In view of the beverage bottle High Density Polyethylene(HDPE)extrusion blowing machine extrusion motor low efficiency,frequent maintenance,a large food and beverage company mechanical and electrical research and development department developed a low speed large torque of permanent magnet synchronous direct drive motor,which can remove the original belt and reduction gearbox,and use the permanent magnet synchronous motor to directly drive the extrusion screw.The practical application shows that the permanent magnet synchronous motor is water-cooled,which can run stably at high temperature to meet the production demand,and also has the advantages of no maintenance and no lubricating oil.The project has obvious energy saving effect,the energy saving rate is 17.1%,which has great economic value,can significantly reduce the equipment vibration and oil pollution,reduce the noise of the beverage production workshop,improve the sanitary environment of the workshop and the working environment of workers,and reduce the failure of reducer and other parts.
