安装extrex6熔体泵使非织造布专家不仅可以满足高质量 要求，而且可以更经济地生产无纺布产品。 齿轮泵使热塑性 聚合物的加工效率大大提高。 新型MAAG齿轮泵extrex6的低压缩齿轮装置在市场上是 独一无二的，特别是允许在高压和低剪切应力下进行输送、 增压和计量应用。 在生产非织造布的特定情况下，这意味着 比流量较之于其他泵的解决方案要高出10％，而驱动轴密封 件的耐磨性和密封能力则提高了25％。 密封件的冷却面积是 传统泵设计的两倍。 熔体通过泵的温度升高降低了40％，并 且熔体泵输出时的脉动最小。 实现了节能12％。 几乎无需维护的设计带来了高有效性和低运行成本。其 他方面的优势还有： 齿轮泵的总体的可靠性、高精度下长期 运行所带来的好处，从而在任何时候都保证着南海南新无纺 布生产线的工艺稳定性。 MAAG集团已经在中国市场上经营了多年，拥有自己的 分支机构和工厂，尽管目前经济形势艰难，但MAAG集团在 挤出设备熔体泵领域的发展仍有望成为创纪录的一年。 仅在 2020年第一季度，MAAG集团在中国的挤出设备熔体泵的销 量就超过了2019年全年。这些泵主要用于生产非织造布和其 他医疗产品。 MAAG集团的extrex产品组合在应用领域、泵送物料和 附件方面具有很高的灵活性。 所有组件均在内部制造，因此 可以满足最高质量要求。 MAAG集团的全球售后服务团队分 布在全球超过18个地点，保证了合格和快速的本地支持。 I n its production of bonded fabrics (nonwovens) for face masks, Chinese manufacturer Nanhai Nanxin Wufangbu is re- lying on a MAAG Groups extrex6 pressure booster melt pump: “We believe Maag offers the best pump solution for nonwoven applications. The Maag pump installed on our nonwovens line has achieved high output and excellent consistency in 24/7 operations. Our expectations as to the reliability and accuracy of the pump have been exceeded, and it has significantly en- hanced the process stability of the line.” The installation of the extrex6 allows the fabric specialist not MAAG Group Aspstr. 12, 8154 Oberglatt, Switzerland www.maag.com only to meet high quality demands, but also to produce the material more economically. The gear pump makes the proces- sing of thermoplastic polymers much more efficient. The low compression gearing of the new MAAG gear pump extrex6 is unique in the market and in particular allows trans- fer, pressure-boosting and dosing applications at high pressure and with low shear stress. In the specific case of the production of nonwovens, this means a 10% higher specific flow volume relative to other pump solutions and 25% better wear resis- tance and sealing capability of the drive shaft seal. The cooling surface of the seal is double that of conventional pump de- signs. The temperature rise through the pump is 40% less, and the pulsations at the melt pump discharge are minimized. The energy saving is 12%. Other advantages in terms of high availability and low operat- ing cost result from the virtually maintenance-free design. In addition to the general reliability of the gear pump, its high accuracy delivers benefits in long-term operation, guaranteeing the process stability of the Nanhai Nanxin Wufangbu produc- tion line at all times. MAAG Group has been operating on the Chinese market for a number of years with its own branch offices and plants, and is heading for a record year in the extrusion pump sector despite the current difficult economic climate. In first quarter 2020 alone, MAAG Group sold more extrusion pumps in China than in the entire year 2019. These will mostly be used for the pro- duction of nonwovens and other medical products. The extrex product portfolio of the MAAG Group offers high flexibility in terms of application, pump materials and accesso- ries. All components are manufactured in-house, and so meet the highest quality demands. The global After Sales Team of the MAAG Group with more than 18 locations worldwide guarantees a qualified and fast local support. 50 工艺 Extrusion Asia Edition 1/2020 www.smart-extrusion.com News about relevant products and events Detailed reviews of various smart technologies Case studies from processors English, German, Russian and Chinese Video clips demonstrating smart equipment in live action Latest magazines available for reading and downloading Weekly e-mail newsletters
