理想塑料齿轮泵

本质上,齿轮泵是在挤出过程中或在化学工业塑料制造过程中输送塑料熔体和其它介质的简单装置,泵轴轮齿咬合紧密。仅由泵体、轴、轴承和轴封填料等少量关键部件构成。仔细观察会发现该系统要比看上去复杂得多。由于MAAG齿轮泵通常加工聚合物熔体,因此在相应受力下,必须清除和考虑长链分子的特性。这时对高温和剪切速率的反应非常重要。还必须考虑在熔体泵中的停留时间和停留时间分布。

塑料制造业在生产过程中要求最高效率,并要求轴承和加工中的聚合物熔体的温升尽可能低。组件之间的间隙越小,效率就越高。然而,这样会影响产品质量,也会影响齿轮泵在挤出过程中的功能。轴和轴承会有卡顿危险。

挤出齿轮泵的研究、开发和制造以及塑料生产加工的其他应用领域是MAAG公司历程的重要部分。在与全球客户数十年的合作中,积累下丰富的知识,在x6级熔体泵中得到了充分体现。如今,化学工业中用于挤出和塑料生产的齿轮泵被用于泵送各种聚合物。不断将新知识运用于熔体泵的开发和改进。

聚合物挤出用理想齿轮泵

良好的容积效率能够实现更低的泵送速度、更低的剪切速率、更低温度和停留时间紧密分布。提升以上属性优化泵送速度、提高聚合物质量、提高可靠性和延长使用寿命。同时,显著降低能耗。MAAG熔体泵和挤出泵都遵循了这一原则。

在塑料制造化学工业中,泵的几何形状对真空排气影响非常大,此时与齿轮泵直接相连的料槽内最低加料水平使停留时间缩短。这对于易降解聚合物的制造商来说特别具有吸引力,因为这意味着可以尽量减少挥发性复合物。特别是x6级齿轮泵实现了极低的 NPSHr(必需汽蚀余量)压力值,因此可以根据泵的尺寸加工高达 200000 Pas(0 剪切粘度)的聚合物熔体。

齿轮泵的工作压力对挤压产品质量有很大影响。压力越高,在泵下游使用的过滤器和换网器就越精细。高容积效率和低脉动确保聚合物品质如一,最终产品产出均匀。

MAAG齿轮泵和挤出泵

泵越小,就越有利于客户的工厂规划。经过优化,MAAG泵机可以在给定的安装空间实现工厂最高生产量。

能源、能源成本和能源消耗是工厂规划的重要领域。MAAG齿轮泵改善了能耗。

MAAG泵机可用于多种聚合物生产加工。高粘度和低粘度产品之间有很大的差异。加工低粘度聚合物时,泵压可以增加。

MAAG挤出泵和熔体泵使用寿命长。由于泵机效率高,x6级熔体泵的轴承温度更低,进一步延长泵的使用寿命,在轴和轴承之间还涂有更稳定的润滑膜。这使得泵机非常可靠。

在聚合物生产中,反应器最优出料方案非常重要。其中的关键是生产过程和其他过程中容器抽提的差异,前者要符合NPSH值(如PET)的标准要求,而后者必须将相连容器中所需的加料水平降至最低。MAAG为熔体抽提泵提供不同的泵体设计以满足不同的要求,从而始终能够在经济和技术上实现最优方案。

MAAG齿轮泵(熔体泵)的扭矩负载能力增强,提高了启动和运行期间的安全性,并有利于总体生产安全。
