movable rotor pump for viscosity liquid (chocolate pump) 1″ Sanitary Lobe Pump with butter-like rotary lobes
Rotary pumps are used in a variety of industries including, pulp and paper, chemical, food, beverage, pharmaceutical, and biotechnology. They are popular in these diverse industries because they offer superb sanitary qualities, high efficiency, reliability, corrosion resistance, and good clean-in-place and sterilize-in-place (CIP/SIP) characteristics.
These pumps offer a variety of lobe options including single, bi-wing, tri-rotary (shown), and multi-rotary. Rotary lobe pumps are non-contacting and have large pumping chambers, allowing them to handle solids such as cherries or olives without damage. They are also used to handle slurries, pastes, yogurt, cream, milk, shampoo and a wide variety of other liquids. If wetted, rotary pump offer self-priming performance. A gentle pumping action minimizes product degradation. Rotary pump also offer reversible flows and can operate dry for long periods of time. Flow is relatively independent of changes in process pressure, so output is constant 和 continuous. 1″ Sanitary Lobe Pump with butter-like rotary lobes

How Rotary Pumps Work – movable rotor pump for viscosity liquid
Rotary pumps are similar to external gear pumps in operation in that fluid flows around the interior of the casing. Unlike external gear pumps, however, the rotarys do not make contact. Rotary contact is prevented by external timing gears located in the gearbox. Pump shaft support bearings are located in the gearbox, and since the bearings are out of the pumped liquid, pressure is limited by bearing location and shaft deflection.

1. As the rotarys come out of mesh, they create expanding volume on the inlet side of the pump. Liquid flows into the cavity and is trapped by the rotarys as they rotate.
2. Liquid travels around the interior of the casing in the pockets between the rotarys and the casing — it does not pass between the rotarys.
3. Finally, the meshing of the rotarys forces liquid through the outlet port under pressure.

Rotary Pump Usage and Applications — movable rotor pump for viscosity liquid
Rotary pumps are frequently used in food applications because rotary pumps handle solids without damaging the product. Particle size pumped can be much larger in rotary pumps than in other sanitary pumps. Since the rotarys do not make contact, and clearances are not as close as in other pumps, this design handles low viscosity liquids with diminished performance. Loading characteristics are not as good as other designs, and suction ability is low. High-viscosity liquids require reduced speeds to achieve satisfactory performance. Reductions of 25% of rated speed and lower are common with high-viscosity liquids.
Common rotary lobe pump applications include, but are not limited to:
- Polymers
- Paper coatings
- Soaps and surfactants
- Paints and dyes
- Rubber and adhesives
- Pharmaceuticals

如何检查真空泵
真空泵是一种从一定空间抽取气体分子并维持部分真空的机器。它的主要功能是在规定的范围内产生相对真空。如果您的真空泵工作不正常，可能需要维修。请继续阅读，了解更多关于真空泵的类型以及如何检查它们的信息。
工业真空泵原理
工业真空泵用于需要真空的工业流程中。这些泵旨在产生、增强和维持真空。了解不同类型的工业真空技术。您可以先阅读有关最常见工业真空泵类型的介绍。这些泵可用于从清洁到制造等各种工业流程。
无论采用何种技术制造这些泵，其基本工作原理都相同。泵的转速和流量决定了其容量和适用性。更快的流量可以最大限度地缩短机器排空所需的时间。另一个需要考虑的重要因素是所需的真空类型。
液环真空泵是一种利用液环形成密封的工业泵。这种泵最适合高蒸汽负荷和高液体夹带的应用场合。液环真空泵可分为两类：液环真空泵和涡旋真空泵。
工业真空泵的工作原理是从腔室中抽取气体分子。由此产生的局部真空允许物质流过空隙。随着更多分子被抽取，腔室内的压力降低，释放出的能量可用于各种不同的用途。
工业真空泵最常见的用途是为电灯供电。在这些灯具中，真空泵抽出气体，使灯泡发光。真空产生的能量也用于飞机，为仪器提供动力。除了为工业吸尘器供电外，它们还应用于各种其他领域。
高性能工业真空系统需要使用能够承受极端压力的特定材料。这意味着这些系统中使用的材料必须经过严格的检验。此外，在安全放入真空腔之前，这些材料必须不含任何有机碎屑和其他污染物。
真空泵的类型
真空泵种类繁多。选择哪种真空泵取决于其用途和所需达到的真空度。真空泵主要分为三类：粗真空或低真空、高真空和超高真空。它们各自具有不同程度的稀缺性。压力越高，每立方厘米的分子数就越少。这反过来又提高了真空质量。
真空泵是真空系统运行的关键部件。根据工作压力范围，真空泵可分为三大类。这些真空泵具有不同的特性和技术，使其适用于特定的应用。针对特定应用选择合适的真空泵取决于所需的真空度和预算。
真空泵广泛应用于各种工业和科研过程中。其主要功能是从密封空间中抽取气体分子，从而形成部分真空。真空泵种类繁多，包括旋转活塞式真空泵、液环式真空泵和涡旋式真空泵。此外，还有涡轮分子泵也被广泛应用。
干式真空泵比湿式真空泵更昂贵。湿式真空泵使用油作为润滑液。根据应用的不同，会使用不同类型的油。一些湿式泵还具有附加功能，例如污染物过滤。然而，湿式系统的一个主要缺点是油与流体直接接触。为了避免这种情况，通常会使用油分离器。
真空泵有多种类型。最基本的类型是容积式泵。它的工作原理是膨胀腔室并排出气体分子。进气阀将流体吸入腔室，而排气阀在腔室达到最大膨胀时打开。这个循环每秒重复数次。容积式泵常用于多级真空系统中。 
真空泵的维护
定期维护对于确保真空泵的长期有效运行至关重要。定期更换泵油是保证泵正常运转的有效方法之一。泵油可能会受到冷凝蒸汽的污染。为避免此问题，在施加真空前，请关闭进气阀 20 至 30 分钟。此外，安装进气冷阱以保护泵免受腐蚀性蒸汽的侵害也十分重要。
延长真空泵使用寿命的另一种方法是定期清除泵内的溶剂。此步骤可减少内部腐蚀，防止泵过早失效。维护时，务必断开真空泵的电源。清洁后，将其存放在干燥安全的地方。泵的处置也应符合当地法规。
真空泵可能需要频繁更换润滑油，尤其是在湿化学领域。通常建议每使用3000小时更换一次润滑油，但有些泵需要更频繁地更换。定期清洁润滑油也很重要，因为脏污或变色的润滑油会影响泵的性能。
真空泵通常配备现场观察窗，方便用户目视检查油位。干净的油呈透明状，而脏油则颜色较深。定期更换机油至关重要，因为这有助于发现各种潜在问题。真空泵性能变化或出现异常噪音也是故障的明显征兆。
更换机油后，应使用软布和温和的脱脂剂彻底清洁真空泵。更换机油只需不到十分钟，就能延长设备的使用寿命。此外，还应使用布或抹布擦拭泵的外部。
泵必须保持良好的通风，以避免内部腐蚀。如果可能，请将泵放置在远离高温设备或房间的地方。过热会降低油的粘度，导致泵过早失效。此外，过热还会导致其他昂贵的科研设备过载运行。高温还会导致橡胶部件开裂和漏油。 
真空泵出现损坏迹象
真空泵故障会导致多种汽车问题，包括油耗增加、刹车失灵、底盘漏油以及空调失灵。如果出现上述任何问题，请联系维修技师检查车辆的真空泵。您也可以检查空调和刹车踏板是否工作正常。
水泵发出巨大噪音也可能是故障的征兆。这些噪音通常是由特定部件老化和磨损造成的。如果是这种情况，可能需要更换隔膜、阀板或密封件。但是，如果噪音来自轴承或其他部位，则可能需要更全面的维修。此外，灰尘和其他污染物也可能进入泵腔，从而降低水泵的性能。
如果真空泵无法启动，可能是保险丝熔断或电源/电压问题。其他常见原因包括入口处的流量限制或安装不当。此外，真空泵本身可能损坏，或者电容器质量不佳。真空泵是否漏油并不总是容易判断，但变速箱油腻可能是真空泵故障的征兆。
真空泵泄漏时，汽车发动机运转时也会发出嘶嘶声。如果听到这种声音，请检查软管和连接处，确保没有泄漏。真空泄漏可能表明真空泵故障，因此需要尽快更换。
检查末端压力很简单，但压力表也可以作为参考指标。您还可以通过运行一个简单的程序来检查泵的振动情况。过度振动可能很细微，但却会对您的工艺流程产生重大影响。如果您发现泵振动过大，应立即联系专业人员。
真空泵性能不佳会给公司带来诸多问题。一台性能差的真空泵不仅会浪费材料，还会损坏您的设备和声誉。
