奶制品厂的问题的过程最后固定后25年!!

美国最大的甜炼乳生产商就在威斯康星州。然而,成功带来挑战。这个主要的乳品生产公司已经处理了一个讨厌的申请超过25年!!

甜炼乳他们尝试了多种策略来,but were still running into problems towards the end of the milk manufacturing process.牛奶和糖的混合物,the primary ingredients in sweetened condensed milk,need to be pumped together from two separate flash coolers.As easy as it sounds on paper,该申请有一些严格的要求。

  • 泵送牛奶和糖的范围从1500到5000厘泊的混合物
  • Pumping 40 GPM,在真空下从两个分开的容器中拉出(24)“28”)
  • 必须保持150磅/秒,同时保持工作温度在70~120°之间
  • CIP在50 GPM拉动2-26在20 psi的容器真空
    • 当使用6%的苛性碱和3%的硝酸时。

One of the owners of the company shared the application's long and challenging history.

“当我们委托蒸发器25年前,we had rotary lobe pumps in this pumping application.The metal-to-metal surfaces wore rapidly.We then switched to sinusoidal pumps.We tried many different elastomers,but never got good pump life.我们在零件上花了很多钱,而且因为泵不能CIP,我们不得不用手洗海豹。

然后我们切换到渐进式空腔泵。我们有良好的定子寿命,but had the same problem with metal-to-metal U-joint wear.We would lose about ½"金属在四个月内,需要更换转子,U形接头,插销和插入轴。

然后,移动到一个不同类型的螺杆泵,we struggled with various failures of the booted sleeve over the U-joint.一旦失败,联合快速失败。

Up until the point that we introduced the NETZSCH progressing cavity pumps,我们可能花了50万美元000处理这种泵应用——包括损失整批的甜炼乳。”“

经过多年的奋斗,公司达到了耐驰一解。他们决定了尼莫®螺杆泵一个灵活的轴会很适合这项工作。专利技术的柔性杆设计无缝隙和死角,这是一个很好的选择,用于食品和饮料的生产。

耐驰尼莫井泵热弹性杆的设计有许多好处如消除免受机械损伤或腐蚀与防护润滑的需要。正因为如此,没有产品污染的风险。The dairy plant was very excited about this because equipment and product reliability is important in the process industry.

乳品厂泵一旦他们收到两耐驰尼莫®泵,他们立即安装。对这两个进行中的空腔泵进行了试验,运行24/7没有维修或性能问题。经过几个月的不间断服务,一个泵被换出来进行检查。The stator and other critical components of the pump were inspected,但没有发现问题或异常磨损。

最后,这个乳制品厂在改建后能节省大量的时间和金钱。The process no longer suffers from long periods of unexpected downtime,允许更好的生产。Plant engineers were so impressed with the performance of the pumps that they're looking to add more NETZSCH pumps in other areas of the business.

这名顾客花了25年的时间才终于解决了他们的问题。If you have a pesky pump problem,别等了!!联系我们现在,我们希望帮助您的进程更有效地运行。

Problem pumps?找出是什么导致了重复的失败,把它修好。
