英国GRIMM格林进口凸轮转子泵概述：
进口凸轮转子泵又称胶体泵、凸轮泵、三叶泵、万用输送泵等，转子泵属于容积泵，输送流量可以较精确的控制也可方便地制成变量泵。此泵的转速很低，一般在200rpm至600rpm之间，被输送的物料被平稳地输出而其成份不会受到破坏。可用于输送粘度很高的物质也可以方便地制成输出压力较高的品种。根据客户管道连接方式的需要，可做成上进下出型转子泵，根据客户安装方式及生产的需要，可做成移动型转子泵，根据客户调节转速及流量的需要，可做成变频调速型转子泵。
转子泵依靠两同步反向转动的转子(齿数为2—4)在旋转过程中于进口处产生吸力(真空度)，从而吸入所要输送的物料。两转子将转子室分隔成几个小空间，并按a→b→c→d的次序运转。运转至位置a时，只有一室中充满介质；到位置b时，B室中封闭了部分介质；到位置C时，A室中也封闭了介质；到位置d时，A室B室与二室相通，介质即被输送至出料口。如此循环往复，介质(物料)即被源源不断输送出去。
转子泵采用联轴整体组装，使体积变小（长度可以减短100-250mm），减少占地面积，结构紧凑，外包不锈钢，镜面抛光，外形美观，档次高，避免原来涂膏刷漆的脱落。性能优化：采用联轴整体组装，减少弹性联轴器功率消耗，噪音及磨损更换而提高工作效率，得到了zui高的效率，zui小的内部滑动和更长的使用寿命。
不同形状的转子具有不同的效果，具体分为以下几大类：
一叶转子：适用于输送含有大颗粒物料的介质，对大颗粒物料的破碎率较低，但其脉动大，压力低，容积量小，很少使用。
二叶转子：适用于输送含有中小颗粒物料的介质，对中小颗粒物料的破碎率相对较低，略有脉动，容积量小于三叶转子。
三叶转子：通用的转子类型，容积量大于其他类型的转子，各种性能指标优于一叶，二叶转子，但其在输送物料的过程中对颗粒物料有一定的破碎率。
传动的选择：
1、电机＋定整比减速器：这样的传动方式简单，转子的转速恒定，也就是决定了流量的不可调性。
2、电机＋机械摩擦式无级变速器：这种变速器的变速靠手动调节来实现，其特点是安全可靠，扭距大，流量无极可调，缺点是非自动调节，较麻烦，调速在运转过程中进行，不得在停机状态下调速，其使用维护参照制造商的使用说明书。
3、变频电机＋变频器：这种方式可实现转速的自动调节，亦即实现了流量的无级调速。其优点是自动化程度高，低速扭距较大，缺点是变频器的价格较高，其使用维护参照制造商的使用说明书。

3、适合于就地CIP清洗与蒸汽消毒，完全符合美国FDA规范要求及医药级(GMP)规范要求。
4、特别适用于在输送过程中容易其泡沫以及输送高粘度、浓度及任何含颗粒的介质，经其输送的物料保持原有品质不变，不起任何理化反应。
5、采用外装动、静环式机械密封，可直接水冲洗，耐高压，不易磨损，无泄漏。
6、体积小，流量大，扬程压力高，适用长距离与高阻力定量输送。
7、泵的叶轮与传动齿轮分开，且在泵腔内各零配件之间保证一定的间隙，相互不接触，无磨损，低噪音，可靠性好，使用寿命长，节能降耗。
8、配置变频器后，可以随意调节流量，并可做一般计量泵使用。

10、结构紧凑，维护方便，几乎无易损件，运行成本低。
11、它不仅具有一般转子泵的的特点，并且在输送高粘度及内含较大颗粒的物料时，也具有一定的优势，对特别粘稠的物料也能够有效输送。经其输送的物料保持原有品质不变。

UK GRIMM Inlet cam rotor pump summary:
imported cam rotor pump, also known as colloid pumps, cam pumps, three leaf pumps, pumps and so on, the rotor pump is a displacement pump, the flow can be more accurate control, but also can be easily made variable pump. The speed of the pump is very low, generally between 200rpm to 600rpm, the transported material is smoothly output, and its components will not be damaged. The utility model can be used for conveying materials with high viscosity, and can also conveniently produce varieties with higher output pressure. According to the needs of customers pipe connection, can make progress under the rotor pump, according to the needs of customers installation and production, can be made into a mobile type rotor pump, according to the needs of customers and the speed of flow regulation, can be made into a variable speed rotary pump.
The rotor pump relies on two simultaneous, reverse rotating rotors (2 to 4 teeth) to generate suction (vacuum) at the inlet during the rotation so as to absorb the material to be conveyed. The two rotor divides the rotor chamber into a few small spaces and runs in the order of a, B, D, C. To the position of a running, only one room filled with medium; to position B, B encloses part of the medium; to the position of C, A in the room also closed to the media; the position of D, A room B chamber and the two chamber, the medium is transported to the discharge port. In this way, the medium (material) is transported continuously.
The rotor pump adopts the whole shaft assembly, so that smaller size (the length can be shortened 100-250mm), to reduce the area, compact structure, coated with stainless steel, mirror polished, beautiful appearance, high grade, avoid dropping original paste paint. Performance Optimization: the overall assembly of the axle reduces the power consumption, noise and wear and tear of the elastic couplings, improves efficiency, achieves the highest efficiency, minimum internal sliding and longer service life.
Rotors of different shapes have different effects, and are divided into the following categories:
Blade rotor: suitable for conveying medium containing large particles of material, the crushing rate of large particles of material is low, but its large fluctuations, low pressure, small volume, rarely used.
Two blade rotor: suitable for conveying medium and small particles of materials, the crushing rate of small and medium-sized materials is relatively low, slightly pulsating, less volume than the trefoil rotor.
Three blade rotor: General rotor type, the volume is greater than other types of rotor, various performance indicators better than a blade, two blade rotor, but in the process of conveying materials, the particle material has a certain rate of fragmentation.
Transmission options:
1.Motor + fixed ratio reducer: this way of transmission is simple, the rotor speed constant, that is to determine the flow of non adjustability.
2.Motor + mechanical friction CVT: the transmission speed by manual adjustment to achieve, it is safe and reliable, large torque, flow rate is adjustable, drawback of non automatic adjustment, more trouble, control in the process of operation, not in the shutdown state governor, referring to the use of maintenance the manufacturer's instructions.
3.Frequency conversion motor + frequency converter: this method can realize the automatic adjustment of speed, that is to realize the stepless speed regulation of flow. The utility model has the advantages of high degree of automation, low speed large torque converter, disadvantage is the higher prices, the use of maintenance according to the manufacturer's instructions.
